SOAR stands for Sydney Outstanding Academic Researcher program.

Extracted from the announcement (link):

The first cohort of fellows of the University’s new Sydney Research Accelerator (SOAR) program has been announced.

In its first year, the program will enable 10 early-career and 10 mid-career researchers to further their research in important areas such as preventing melanoma, preparing us for the next global pandemic, building more powerful batteries for electric cars and helping those from disadvantaged backgrounds succeed in education.

As part of their two-year program, fellows are awarded $50,000 per year to support their research, innovation and development plans. They also benefit from a personalised program of research development support and structured mentoring.

Deputy Vice-Chancellor (Research) Professor Duncan Ivison said the program recognises and develops the University’s most talented researchers as part of the University’s 2016-20 unprecedented investment in research.

“Through SOAR, we will support up-and-coming research leaders to build momentum and increase the scale and impact of their research.”

“At the University of Sydney, we want to celebrate and nurture high-performing researchers to realise their full potential and SOAR is just one of the many new programs we are developing to do just that.”

Professor Ivison said the program would allow our best and most promising researchers more opportunity to fast-track their career development and position them as pioneers in new fields. It will help them build leadership skills and aid the development of new partnerships with industry and other leading academics around the world.

Dr Andrew Black, Director of Research Development and Collaboration, said the program received an overwhelming level of interest.

“The volume and calibre of the applicants was extremely high, which highlights the University’s ability to attract leading researchers across a variety of disciplines. With the demand and early success of the program, we hope to increase the number of fellowships offered in 2018.”

Highlighting the University’s commitment to gender equity, 50 percent of the fellowships were awarded to women.

Professor Marc Kamlah is visiting the lab

My former PhD advisor, Professor Marc Kamlah from Karlsruhe Institute of Technology (KIT) Germany, is visiting the lab for four weeks. Marc is the group leader and now acting as the head of Institute of Applied Materials – Mechanics of Materials and Biomechanics (IAM-WMB) where over 60 Scientists work experimentally and theoretically in the field of the mechanics of materials and bio-mechanics. More details about IAM-WMB via https://www.iam.kit.edu/wbm/index.php

He will attend later the International Workshop on Mechanics of Energy Materials (IWMEM 2016) at The University of Sydney.

Mr Oleg Birkholz is visiting the lab

Mr Oleg Birkholz from Karlsruhe Institute of Technology (KIT), Germany is visiting us at The University of Sydney. Oleg is working on the numerical aspects of modelling lithium-ion battery systems, via the discrete element method and resistor-capacity (RC) network. He will stay with us for two months and working on modelling electro-mechanical properties of granular energy systems.

Paper online, TAML

Liu, M., Jin, P., Xu, Z., Hanaor, D.A.H., Gan, Y., Chen, C.Q. (2016)  Two-dimensional modeling of the self-limiting oxidation in silicon and tungsten nanowires. Theoretical and Applied Mechanics Letters. in press. [DOI]

TAML2016

Abstract: Self-limiting oxidation of nanowires has been previously described as a reaction- or diffusion-controlled process. In this letter, the concept of finite reactive region is introduced into a diffusion-controlled model, based upon which a two-dimensional cylindrical kinetics model is developed for the oxidation of silicon nanowires and is extended for tungsten. In the model, diffusivity is affected by the expansive oxidation reaction induced stress. The dependency of the oxidation upon curvature and temperature is modeled. Good agreement between the model predictions and available experimental data is obtained. The developed model serves to quantify the oxidation in two-dimensional nanostructures and is expected to facilitate their fabrication via thermal oxidation techniques.

Keywords: Self-limiting oxidation; Finite reactive region; Kinetics model; Nanowires
