Funded PhD Project (Students Worldwide)
Many natural materials exhibit extraordinary properties. For example, butterfly wings are highly coloured despite not containing dye molecules and mollusc shells exhibit high fracture toughness despite being comprised of 95% of a brittle mineral. These properties are dictated by the spatial orientation of nanostructures that make up the materials over many length scales, hence the ability to control structural hierarchy when designing new materials is crucial to obtain outstanding properties. Our recent discovery of a Liquid crystal hydroglass (LCH) provides an exciting avenue to control the structural hierarchy and hence properties of soft materials. LCH is a biphasic soft material with flow programmable anisotropy that forms via phase separation in suspensions of charged colloidal rods upon increases in ionic strength.
This project aims to expand on the materials space for LCH materials in order to create viscoelastic materials with complex rheology as well as structural, mechanical and optical heterogeneity. The intended outcome is enabling the creation of anisotropic materials with shape-memory and shape-restoring features for the realization of artificial muscles, novel biomedical devices, soft robotics and morphing structures.
Only one studentship is available, but HDR student has a choice between two potential work streams:
Work stream 1 aims to develop thermo- and/or photo-responsive LCH materials by surface functionalising nanocrystalline cellulose (NCC) colloidal rods. The student will design and synthesise block copolymers that self-assemble to the surface of the nanocellulose and characterise their interfacial chemistry and phase behaviour.
Alternatively, Workstream 2 aims to explore and diversify the materials space for LCH materials and their rheological properties. This project will vary solution properties and matrix rheology/composition for NCC suspensions, as well as investigate the presence and properties of LCH phases in a diverse range of anisotropic charged colloids.
The project is part of an Australian Research Council Discovery Project involving collaboration between School of Chemical Engineering, Australian Institute for Bioengineering and Nanotechnology, Centre for Advanced Imaging, Centre for Microscopy and Microanalysis at the UQ, and the Australian Nuclear Science and Technology Organisation (ANSTO).
The successful candidate must commence by Research Quarter 1, 2021. It is thus preferable that applicants already reside in Australia due to current travel restrictions.

Nano-rectenna devices for Space applications
( Italian Institute of Technology |School in Science and Technology of Chemistry and Materials - Nanochemistry Curriculum | Genoa | ）
Supervisor：Dr R Proietti Zaccaria
Application Deadline：Monday, June 15, 2020
Funded PhD Project (Students Worldwide)
Tutor: Remo Proietti Zaccaria
Photovoltaic systems are one of the examples where extremely strong investments have lead to the realization of exceptional devices. Even though extremely successful, photovoltaic systems are not perfect as they suffer of some issues. For example, single layer Si crystal PV systems cannot provide an efficiency higher than ~34% due to the well known Shockley–Queisser limit and they strongly depend on the surrounding temperature. Here we shall work on a very different paradigm, where light is turned into electricity through completely different mechanisms which do not suffer from the aforementioned limit and are more robust in terms of temperature change. Specifically, the PhD work activity will address the experimental analysis of solar energy harvesting devices known as rectennas, by identifying the solutions capable of ameliorating the issues which presently limit rectennas from becoming viable devices for solar energy harvesting. In particular, a particular attention will be dedicated to the idea of employing this systems for Space related activities.
The activity will be run within the DELTA Lab of the Italian Institute of Technology in close collaboration with the Italian and European Space Agencies. The candidate will have access to a fully equipped opto-electric characterization lab, to a micro/nano fabrication facility and to a wide range of material characterizations instruments. Collaboration with theoreticians will be conducted on daily basis.
The candidates should have a background in physics, optics or material science. Importantly, candidates should be driven by strong interest in solving physics-related problems and strong work dedication. Work experience in the theoretical design of optical antennas will be positively considered.

Supervisor：Dr Andrea Erxleben
Application Deadline：Tuesday, September 01, 2020
Funded PhD Project (Students Worldwide)
Applications are invited for a fully funded PhD position( €18,500 per annum stipend plus €5,500 tuition fee)s in the pharmaceutical and medicinal chemistry group led by Dr Andrea Erxleben at the National University of Ireland, Galway. The position is funded through the Synthesis and Solid State Pharmaceutical Centre (SSPC), a collaboration of 9 Irish university institutions and 15 industry partners, funded by Science Foundation Ireland and the Irish pharmaceutical industry.
The PhD student will develop and study multi-component pharmaceutical materials with enhanced physicochemical properties. Poor physicochemical properties such as low chemical and physical stability, poor flow properties, poor compressibility or slow dissolution rates can have a severe impact on the shelf-life, manufacturability, bioavailability and therapeutic efficacy of a drug. Cocrystallization of a drug with a biologically inactive coformer has recently emerged as a strategy to optimize and fine-tune the physicochemical properties of a drug without making chemical changes to the drug molecule itself and a number of pharmaceutical cocrystals have entered the market in the past few years. Cocrystallization becomes an even more powerful approach when the inactive coformer is replaced with a second complementary drug and opens the door to new fixed dose combination formulations. In this project crystal engineering will be applied to design novel cocrystals of tuberculosis, malaria, antidiabetic and antihypertensive drugs. The student will be trained in the use of different analytical techniques including single crystal X-ray analysis, x-ray powder diffraction, scanning electron microscopy, differential scanning calorimetry and infrared- and near-infrared-spectroscopy.
To apply
Please send applications (cover letter, curriculum vitae, academic transcripts, names and contact details of two academic references) in pdf format to Dr Andrea Erxleben at andrea.erxleben@nuigalway.ie. The successful candidate will have an excellent academic record, is able to work independently and is highly motivated to participate in a dynamic research team.
