Reconfigurable Systems - Towards Zero Waste

Assembly dynamics of advanced colloids

How can we control 3D assemblies of colloidal particles? Development of smart, reusable self-assembling colloids will be a critical aspect of future sustainable materials. Self-assemblies are already attracting interest for applications such as catalysis and photonic crystals, but the potential range of functionality and applications is near-limitless. This funded PhD project will use microfluidics to experimentally study the dynamics of assembly for interesting types of colloids, including small clusters of asymmetric Janus (or 'patchy') particles. The goal is to build fundamental understanding that will allow us to manipulate colloids, especially those (such as hydrogels, Pickering emulsions, and light-responsive vesicles) that are of interest to our colleagues in the MacDiarmid Institute.

Ideal candidate

We are looking for students with a strong Honours or Masters degree in physics, chemistry, engineering, or a related field. Experience with one or more of experimental physical chemistry, microfabrication, experimental fluid dynamics, or optics and image analysis would be beneficial.

Exploring electromechanical coupling in functionalised biological materials

This PhD project aims to further the understanding of electromechanical coupling in biological materials and to use that understanding to create sustainable energy harvesting devices.

First, this project will focus on amyloid protein/peptide assemblies with high, and known, ordering of the beta-sheet amyloid structure. The structure will be optimised for piezoelectric charge generation, and we will use computational modelling to understand the effective dipole moment in the materials.

Secondly, this project will also explore functionalisation of the amyloid fibres using either nanoparticles/clusters to enhance the piezoelectric output, or nanoparticles/clusters capable of 'reporting' on for example surface potential or charge. The aim of this would be to create a system where strain generated changes to charge/surface potential lead to a change in for example catalytic activity.

The work will include expression of functional amyloids in E-coli, material processing and characterisation and computational modelling, ensuring a diverse and rich research experience for the PhD candidate.

Ideal candidate

The ideal candidate will have an engineering or science degree in materials, chemistry, or biophysics, experience working with biological or soft materials, an interest in both experimental research and computational modelling and be able to work in an interdisciplinary team.

Enhancing the functionality and circularity of silicone vitrimers with a view towards commercial applications

Thermoset polymers, such as silicone, have excellent mechanical properties and resistance to solvent and heat, but are particularly challenging to recycle as they cannot be thermally processed and remoulded, as is possible with thermoplastics (eg polyethylene). We've recently developed chemistry to combine sulfides (S-S chains) with silicones (Si-O chains) via crosslinking by intercepting the curing process for commercial silicone. Incorporating dynamic S-S bonds with the ability to cleave and recombine creates a silicone vitrimer, a material which is now processable and repairable. The PhD project will build on this preliminary research with the goal of transferring the technology to other types of silicone at a scale beyond the bench, while simultaneously incorporating new functionality, testing the extra properties afforded by sulfur, exploring applications, and improving the circularity of silicone both through recycling and disassembly strategies.

Ideal candidate

We are looking for a candidate with a background in polymer synthesis and characterisation. Experience working with silicone and/or in polymer recycling is desirable.

Pickering emulsion-based strategies for compartmentalisation of polymer coacervates

This project will formulate and characterise emulsions that contain polymer coacervate compartments. When aqueous solutions of oppositely charged biopolymers are mixed together, the polymers can complex together into cell-like compartments that separate out from the water. Our research question is about how we can use emulsions stabilised by nanoparticles (called Pickering emulsions) to encapsulate and protect these compartments, so they can function like artificial cells. The project will investigate how to manipulate the compartment configurations in the emulsions and how to control encapsulation and reaction of ingredients within the compartments. This is an exciting opportunity to make real breakthroughs using microscopy and scattering techniques and tools that measure liquid flow to probe the structure and function of these new materials. The successful candidate will join the School of Food Technology and Natural Sciences on the Palmerston North campus of Massey University in New Zealand.

Ideal candidate

BSc Honours or MSc degree (or equivalent) in chemistry, materials science or similar. Knowledge and experience in colloidal and surface chemistry techniques is an advantage. We are seeking a highly motivated person with an excellent academic record, and able to work well in a team.

Guiding hierarchical assemblies of spores to move cargo

Zoospore are motile spores that use a flagellum for locomotion in aqueous or moist environments. These spores are created by, amongst others, fungi and oomycetes to propagate themselves. Exhibiting electro- and chemotaxic sensing, these spores provide an interesting model for navigation and aggregation strategies. This project will make use of our existing electro- and chemotaxis microfluidic platforms to demonstrate reversible assembly of spores in 2D and 3D. For 3D assembly, new electrotactic devices will be developed based on 2-photon polymerisation 3D printing. The project will further adopt existing optical and magnetic control approaches for microparticle swarms, and related chemical attachment strategies to produce higher order assemblies. Assembled spore arrangements will either be directly used to demonstrate in-situ metal nanoparticle synthesis, followed by spore termination using Joule heating, or as a carrier by DNA-mediated attachment of functional micro-/nanoparticles. As part of the project the student will develop highly interdisciplinary skills, working at the interface between engineering, biology and chemistry, and will be exposed to state-of-the-art device fabrication, experimental design and characterisation techniques.

Ideal candidate

Background in applying microfluidic techniques to the study of microorganisms. Engineering candidates should have experience in the fabrication and use of lab-on-a-chip devices, and be keen to apply these to fungal/oomycete cells. Biologists would have prior experience with the culture and maintenance of fungal/oomycete microorganisms and would be interested in expanding their experimental technique to microfluidic platforms. Specialised training in either area will be provided.

Future Computing - Towards Low Energy Tech

Altermagnetism in low dimensional d-wave superconductors and chalcogenides

Altermagnetism is a newly discovered phase of magnetism distinct from ferromagnetism (where spins align parallel) and antiferromagnetism (where spins align antiparallel). In altermagnets, the magnetic moments are arranged in an antiparallel manner, but unlike conventional antiferromagnets, the arrangement is such that the magnetic sublattices are connected only by rotational symmetry. This property makes altermagnetism an intriguing area of research with potential applications in spintronics. We aim to gain a better understanding of the coupled order of several candidate materials and work towards device applications using superconductor/altermagnet heterostructures for energy-efficient switching and rectifying devices.

This project will investigate altermagnetism in d-wave superconductors (eg, La₂CuO₄) and chalcogenide (eg, MnTe) thin film samples. Strain engineering will be achieved by growing these films on lattice-mismatched substrates and buffer layers. We will also grow films on single crystals – eg, La₂CuO₄ on Bi₂Sr₂CaCu₂O_8+δ superconducting single crystals, and MnTe on FeSe_1-xTe_x superconducting single crystals. The project will also involve thin film deposition, ambient and high-pressure magnetisation measurements, and magneto-transport characterisation, performing photometric reflectivity measurements on a Bruker Vertex 80v interferometer and exploring altermagnetism using the concept of non-linear phonon interactions via ultrafast laser spectroscopy.

Ideal candidate

The ideal candidate we are looking for will possess knowledge and skills in thin film deposition (eg, magnetron sputtering or PLD) and will have a strong background in magnetism and/or superconductivity.

Molecular functionalisation of self-assembled neuromorphic devices

The aim in this project is to functionalise our self-assembled neuromorphic devices with particular molecules and to demonstrate brain-like computation. The project will most likely involve lab work (nanofabrication techniques, some chemistry, high speed electrical measurement techniques, implementation of the computational algorithms) but may include numerical modelling work. The overarching goal is essentially to demonstrate memristive behaviour in molecular systems and build it into our devices. The science challenge is to understand the way in which memory ("molecular synapses") affects the properties of the "spiking neurons" that already exist in our networks. The technical aim is to add memory to the devices so as to enable new computational capabilities. Papers describing the fabrication and neuromorphic properties of the devices can be found here.

Ferroelectric and multiferroic nitride thin films for future computing

Our research focuses on developing quantum materials with engineered interfaces to unlock new functionalities driven by spin and quantum effects. These materials hold the potential to revolutionize nanoelectronics beyond conventional silicon CMOS, enabling next-generation sensors, actuators, and energy-efficient computing technologies. By harnessing the unique properties of nitride perovskites, this project contributes to a broader effort in discovering materials that combine functional properties with practical manufacturability.

This PhD project will explore novel epitaxial nitride perovskite thin films as a platform for next-generation computing. By coupling their piezoelectric properties with the ferromagnetism and spin textures of rare-earth (RE) nitrides, these materials offer exciting new possibilities for energy-efficient computation. While oxide perovskites (ABO₃) have demonstrated significant potential in "oxide electronics," their integration into conventional semiconductor fabrication remains challenging. Recently, nitride perovskites (ABN₃), such as LaWN₃, have been successfully synthesised in thin-film form and are predicted to exhibit multiferroic properties. This project aims to develop new nitride ferroelectrics and multiferroics, integrating them with RE nitrides to pave the way for innovative computational paradigms.

Ideal candidate

The successful candidate should have a solid background in physics, materials science, or a related field. Experience with thin-film deposition, x-ray diffraction and/or crystallography, scanning probe microscopy, or electronic transport measurements is desirable. A keen interest in quantum materials and device physics will be advantageous.

Immobilised electrocatalysts for CO₂ reduction into commodity chemicals

Designer molecular catalysts will be made, characterised and immobilised – using our established covalent and spray/pyrolysis methods – before testing them as heterogeneous electrocatalysts for the CO₂ reduction reaction (CO₂RR), and hydrogen evolution reaction (HER). Recent data for an immobilised macrocyclic complex revealed robust CO₂RR resulting in up to 82% of the CO₂ being reduced to formate, and that the formate:acetate product ratio is dependent on the applied voltage. A key aim of this PhD project will be the further exploitation of these exciting systems. The candidate will gain a wide range of hands-on experience at both Otago and Canterbury Universities.

Fluidisation behaviour of metal organic frameworks

Fluidisation occurs when gas is flowed through a bed of powdered materials. This achieves fast rates of mass transfer (reactions or adsorption) and heat transfer (controlling reaction kinetics and equilibrium compositions). 'Faster' has massive advantages in process design and economics!

Metal-organic frameworks (MOFs) are coordination complexes with exceptionally high surface area to volume ratios and have been widely investigated for catalysis and gas separation applications. This PhD project will address the practical problems that confront using MOFs in fluidised processes, with the aim to lead to fundamental insights that unleash the power of MOFs for catalysis.

Ideal candidate

A chemistry or chemical and process engineering student interested in learning how to design and control catalytic processes, with a willingness to engage with both equipment design and operation, alongside understanding of reaction chemistry, and mathematical descriptions of fluidisation behaviour and catalysis processes.

Application of low frequency Raman spectroscopy to evaluation and design of new materials

We seek to adapt and improve low frequency Raman spectroscopy as an analytical technique. A key scientific advantage of low frequency Raman spectroscopy is the ability to detect order in systems. Having such techniques is nice but we need to understand how they work for different systems and how we can adapt the technique as required. A key focus here is engaging with existing projects and adding value to those with spectroscopic expertise and, where appropriate, modelling spectra. Key areas of interest are: metal-organic frameworks; organic and inorganic electronic systems - such as donor-acceptor materials - with a focus to catalysis; ionic liquids in porous media and fibres. There are a wide range of possible systems to investigate but the primary focus of this project would be the enhancement and development of our existing low frequency Raman systems.

Ideal candidate

Student with some spectroscopic background, possibly in optics. Some experience in calculations. An ability to work with other people to achieve project aims.

Plasma-assisted electrochemical ammonia synthesis

Ammonia (NH₃) is one of the world's most important industrial chemicals, widely used in the manufacture of fertilisers. Currently, ammonia is synthesised by the Haber-Bosch process which has a very large carbon footprint. Researchers are now seeking alternative and greener ways of synthesising ammonia. Recently, Dr. Ziyun Wang (University of Auckland) and I published the paper "Controlling the Reaction Pathways of Mixed NO_xH_y Reactants in Plasma-Electrochemical Ammonia Synthesis" in Journal of the American Chemical Society (J. Am. Chem. Soc. 2024, 146, 51, 35305–35312). In this work, we reported the successful development of a continuous flow plasma-electrochemical reactor system for the direct conversion of nitrogen from air into ammonia. In our system, nitrogen molecules are first converted into a mixture of NO_x species in the plasma reactor, which are then fed into an electrochemical reactor to convert the generated NO_x species into NH₃. Using a CuPd foam catalyst as the cathode catalyst in the electrolyser, a remarkable ammonia production rate of 81.2 mg h^–1 cm^–2 was achieved with excellent stability over 1000 h at an applied current of 2 A. This project will continue this exciting work, developing high-performance electrocatalysts for NO_x reduction to NH₃.

Ideal candidate

The ideal candidate will be highly self-motivated, with previous experience in the design, characterisation and testing of electrocatalysts for processes such as NO_xRR, CO₂RR, ORR and/or HER, and a good track record of publishing in international peer reviewed journals.

MOF-derived electrocatalysts for carbon dioxide conversion

Carbon dioxide can be converted into value-added chemicals using electrochemistry. Ideally powered by renewable energy, this approach uses the electrochemical reduction of carbon dioxide at the surface of an electrocatalyst. The reaction rate and product selectivity depends on the properties of the electrocatalyst (and the chemical environment in which the reaction occurs).

This project will involve the synthesis of MOF materials, conversion of these materials into highly conductive layers, and then integration of these materials into carbon dioxide electrolysis flow cells. The three key aims of the PhD project are:

• Develop MOF-derived electrocatalysts for carbon dioxide reduction, through the direct growth of MOF layers on carbon felt gas-diffusion electrode surfaces followed by pyrolysis.
• Integrate the newly developed MOF-derived electrocatalysts into carbon dioxide electrolysis flow cells.
• Characterise and optimise the performance of MOF-derived electrocatalysts in electrolysis cells to enhance efficiency and selectivity.

Ideal candidate

The idea candidate will have a good university degree (1st or 2:1) in chemistry, physics, nanoscience or a related subject, be highly motivated and be able to work both independently and as part of a team. Full training will be given in all aspects of the project.

Thermally sprayed synthetic high-silica volcanic glass formation to study the critical phase reactivity of pozzolanic pumice in concrete

Modern concrete production relies on Portland cement, which has a significant CO₂ footprint (5%-8% of global greenhouse emissions). One of the most common methods to reduce the carbon footprint of concrete is by using Supplementary Cementitious Materials (SCMs), with significant research attention and industrial interest being paid to the application of natural pozzolans. Pumice is a volcanic glass produced during explosive eruptions and is abundant in New Zealand. It is a proven natural pozzolan with the capacity to harden into a cementitious material when used as a partial cement replacement in concrete.

The PhD student allocated to this work will be part of a wider team investigating New Zealand pumice as a partial cement replacement in New Zealand cements. As a naturally produced material, pumice has a complex elemental and phase composition, together with a marked variability in the amorphous-to-crystalline structure ratio. All of these variables potentially play a role in the degree to which pumice acts as a SCM. It is challenging to identify the critical variables defining the SCM response with natural pumice materials because there is no way to independently control them.

Chemical programming of mixed-matrix membranes for CO₂ capture

Carbon dioxide (CO₂) levels are causing a global environmental crisis. Mitigating this crisis will require new effective approaches to reducing CO₂ emissions. Mixed-matrix membranes (MMMs) present an attractive option for CO₂ capture. MMMs are made by incorporating a porous filler into a polymer matrix, and they combine the merits of both materials. However, these membranes suffer from several drawbacks, including limited precision in the discrimination of CO₂ from other gases and undesired void spaces due to incompatibilities between the filler and the matrix.

This PhD project will develop new mixed-matrix membranes by incorporating metal-organic framework (MOF) fillers into polymer matrices. The primary focus will be to systematically programme the properties of the MOF fillers to improve the interfacial compatibility and enhance the CO₂ separation performance. In addition to exploring the separation mechanisms at an atomic level, this project will generate new insights to inform the future design of the CO₂ capture membranes.

The PhD student will gain familiarity with a wide range of material synthesis techniques and characterisation methods including SEM, TGA/DSC, XRD, physisorption and more. They will also become experts in experimental and computational membrane analysis. The student will be enrolled at the Victoria University of Wellington under the supervision of Dr Ben Yin and Professor Shane Telfer, and is expected to spend time at Massey University in Palmerton North over the course of their PhD studies. The student will also collaborate with our key partner investigators from the wider MacDiarmid Institute and internationally.

Eligibility

The applicant should hold a 4-year BSc(Hons), MSc/MEng or equivalent degree in Chemical Engineering, Materials Science/Engineering, Chemistry or a related discipline. Previous laboratory experience in porous materials synthesis and membrane research will be advantageous. Candidates should satisfy the requirements for admission as a PhD candidate at Victoria University of Wellington.

Total value and tenure of scholarship

NZD$35,000 per annum (not taxed), plus all student fees for three (3) years.

How to apply

To apply, please send a CV and academic record to Dr Ben Yin, ben.yin@vuw.ac.nz, with “CO₂ capture membrane” in the subject line. A shortlist of qualified applicants will then be invited to make a formal application for PhD study at Victoria University of Wellington.

Materials science or chemical engineering for the development of novel controlled-release fertilisers and manufacturing processes

The New Materials and Technologies Development Research Team led by Professor James Johnston in the School of Chemical and Physical Sciences, Te Herenga Waka - Victoria University of Wellington, is seeking a highly motivated and dedicated PhD candidate in chemistry, materials science or chemical engineering (or similar), to contribute to our research programme on the development, characterisation, applications, and manufacture of new materials and products derived from our proprietary, nanostructured calcium silicate material, produced sustainability from geothermal resources. 

The successful candidate will be an integral part of a dynamic and multi-disciplinary research team working on the chemistry and process engineering, manufacturing methods, performance testing, and refinement of novel controlled-release fertilisers and other materials, that utilise the proprietary nanostructured calcium silicate (CaSil) material together with expertise and knowhow developed by the team.

This PhD project combines particular aspects of chemistry, engineering, and agriculture. It has the potential to contribute to more sustainable agricultural and horticultural farming practices. The overall aim of the research area is to develop, characterise, optimise and demonstrate the effectiveness of new and more efficient fertiliser products where the nutrient availability from the fertiliser matches plant demand more closely, thereby reducing the run-off of excess nutrients to surface waters and preventing pollution.

The PhD research project will involve further developing our understanding of the chemistry, characteristics and performance properties of these nanostructured calcium silicate based composite fertiliser materials, together with scaling the science and technology to pilot plant operation and production. Also on-farm trials of the composite fertilisers produced. The research will be guided by the propensity to upscale the science and engineering to commercial scale and the overall technical and economic feasibility.

The PhD candidate will utilise and build upon the substantial proprietary knowledge already developed by the team on the laboratory scale development and glasshouse demonstration of CaSil-based fertiliser products, together with our experience in scale-up, pilot plant operation and product performance testing.

Processing and characterisation of Ti-Fe alloys as H₂ storage materials from NZ feedstocks (2 PhD scholarships)

Green hydrogen will become a pivotal vector to carry and store renewable energy in a future net-zero carbon New Zealand. Ti-Fe alloys demonstrate high hydrogen uptake at ambient conditions and are an attractive candidate material for stationary bulk hydrogen storage applications. Nevertheless, several key issues require further investigation, such as surface activation, cycle stability, impurity tolerance, and supply volume of the metallic feedstocks.

Two PhD candidates will explore the production and processing of Ti-Fe alloys from New Zealand-sourced feedstocks using metallurgical and mechanochemical methods as part of collaborative research within the German-New Zealand Green Hydrogen alliance. The alloys prepared will be characterised by a range of methods (XRD, SEM/EDS, ICP-MS, XRF, DSC), and their hydrogen storage capacity and kinetics studied using custom ‘Sieverts apparatus’. Furthermore, the presence of common impurities within the Ti-Fe alloys will be systematically studied to better understand how locally-sourced feedstocks are likely to perform as hydrogen storage materials, including the effect of surface impurities on reactivity/diffusion characteristics.

Supervision and support for the project will be provided by staff at the University of Otago and University of Canterbury, New Zealand, and the Institute of Hydrogen Technology, Helmholtz-Zentrum Hereon, Germany. The students will be enrolled at the University of Otago, but it is expected that the candidates will spend time at both the New Zealand and German host institutions over the course of the PhD studies

Eligibility

The applicant needs a degree equivalent to the 4-year BSc (Honours) degree in New Zealand, with 1st class Honours, or an MSc or Postgraduate Diploma in Chemistry, Materials Science, Engineering, or equivalent. Practical experience with hydrogen materials, metallurgy, mechanochemistry and/or the characterisation techniques listed above will be advantageous. Māori and Pasifika students are particularly encouraged to apply. Candidates should satisfy the requirements for admission as a Ph.D. candidate at the University of Otago.

Total value and tenure of scholarship

The PhD scholarship will include tuition fees and a stipend of $30,000 p.a. (tax-free) for three years.

How to apply

To apply, please send your full CV, including academic record, research experience, and the names and contact details of two referees, to: Associate Professor Nigel Lucas, nigel.lucas@otago.ac.nz, and Associate Professor Alex Yip alex.yip@canterbury.ac.nz, with “Hydrogen storage materials PhD” in the subject line.

Design, synthesis and advanced characterisation of electrocatalysts for the oxygen evolution reaction in anion exchange membrane electrolysers

This programme aims to develop above state-of-the-art anode materials for the anion exchange membrane electrolyser (AEMEL) technology using low-cost and abundant materials. Currently, the anode overpotential makes up the majority part of the inefficiencies of an AEMEL system. By developing more efficient anode materials a significant increase in the efficiency of hydrogen production using AEMEL technology is possible. This in turn will help accelerate the formation of a green hydrogen economy and thus support the Governmental climate change goals in Germany and New Zealand.

This programme has 3 PhD projects available. These include:

Project 1: In-situ characterisation of anode materials operating under oxygen evolution conditions.

This project will include:

• Developing synchrotron based x-ray methods (x-ray absorption spectroscopy and x-ray diffraction) to characterise anodes during oxygen evolution
• In-situ Raman spectroscopy of anodes during oxygen evolution
• Voltametric and impedance analysis of electrocatalytic oxygen evolution electrodes

Project 1 is based at University of Canterbury, Christchurch, NZ, under the supervision of Professor Aaron Marshall.

Project 2: Tomographic analysis of gas evolving electrodes.

This project will include:

• Use of synchrotron x-ray tomography on porous and gas evolving electrodes
• Use of MRI for characterising porous and gas evolving electrodes
• Understanding of role of porous structures during gas evolution

Project 2 is based at University of Canterbury, Christchurch, NZ, under the supervision of Professors Daniel Holland and Aaron Marshall.

Project 3: Scanning Electrochemical Microscopy of gas evolving electrodes.

This project will include:

• Use of Scanning Electrochemical Cell Microscopy of novel electrocatalytic electrodes
• Mapping electrocatalytic activity at sub-micron scales
• Apply scanning probe methods to characterise electrocatalytic composites

Hydrogen generation with sustainable resources – a combined molecular, computational and engineering approach

There are three PhD positions available in Chemistry at the University of Otago two positions in synthetic inorganic chemistry and one in spectroscopy of inorganic systems. The supervisors are Professor James Crowley and Professor Keith Gordon.

Hydrogen is an important fuel source and commodity chemical used in a wide range of industrial processes. Unfortunately, almost all the hydrogen produced currently is obtained from the steam reforming process which is both energy intensive and generates carbon dioxide as a by-product. There are already several photocatalytic systems, including bimetallic metal complexes that can efficiently generate hydrogen in this way. However, the current technologies use Noble metals which are expensive and rare. We will use earth abundant transition metals such as iron, cobalt and copper by re-designing the photocatalytic systems. This project is a Marsden funded project involving researchers in Jena, Germany (Profs Kupfer, Shilitto and Weigand) and Nottingham, UK (Prof George) The project may involve visits to collaborators in Germany and the UK.

Kindly contact either jcrowley@chemistry.otago.ac.nz or keith.gordon@otago.ac.nz with any questions.

Eligibility

The projects involve the synthesis of new metal complexes and their study using spectroscopy and computational chemistry. Two of the researchers will focus more on synthesis with the third undertaking computational studies and spectroscopic measurements including transient spectroscopy. Some overlap of expertise and interest is welcome. Experience in any of these areas is useful.

Total value and tenure of scholarship

The scholarship provides a non-taxed stipend of NZD$35,000 per annum plus the PhD tuition fee for three years.

How to apply

As part of your application package, kindly include:

• CV (including 2-3 referee information)
• Cover Letter (this may include: a description of why you want to undertake a PhD; how your previous experiences have prepared you for the research project that you are applying for; what your passions are within or outside of academia)

Applications should be sent to jcrowley@chemistry.otago.ac.nz or keith.gordon@otago.ac.nz and will be accepted beginning February 2024 until the positions are filled.
