Trosolwg

Astudiodd Emrys Evans Gemeg ym Mhrifysgol Rhydychen (cafodd MChem yn 2012 a DPhil yn 2016, dan oruchwyliaeth yr Athro Christiane Timmel). Roedd ei brosiect PhD ar destun ffiseg ffoto a throelli parau radicalaidd a ysgogir gan olau sy'n gysylltiedig â magnetodderbyn ar gyfer llywio anifeiliaid. Ar ôl hyn, bu'n gweithio gyda'r Athro Syr Richard Friend yn Labordy Cavendish, Prifysgol Caergrawnt fel Cydymaith Ymchwil (2016-2019) a Chymrawd Gyrfa Gynnar Ymddiriedolaeth Leverhulme (2019-2020). Yng Nghaergrawnt, cynhaliodd ymchwil ar led-ddargludyddion organig a deunyddiau radicalaidd ar gyfer optoelectroneg mewn cydweithrediad â'r Athro Feng Li, Prifysgol Jilin. Yn 2020, dyfarnwyd iddo Gymrodoriaeth Ymchwil Prifysgol gan y Gymdeithas Frenhinol i arwain ymchwil ym Mhrifysgol Abertawe ar 'Ynni radicalaidd a rheoli troelli mewn electroneg organig.' Yn 2021, dyfarnwyd Medal Dillwyn iddo am STEMM gan Gymdeithas Ddysgedig Cymru i gydnabod rhagoriaeth ymchwil gyrfa gynnar am ei waith ym maes optoelectroneg. Yn 2022 derbyniodd wobr Seren Ymchwil ac Arloesi'r Dyfodol gan Brifysgol Abertawe.

Uchafbwyntiau Gyrfa

Ymchwil

Mae gan radicaliaid electronau heb eu paru, gan arwain at gemeg a ffiseg anarferol y gellid eu defnyddio mewn electroneg organig a thechnolegau moleciwlaidd y genhedlaeth nesaf. Mae ymchwil Emrys yn archwilio swyddogaethau newydd sy'n deillio o ymoleuedd, magnetedd a phriodweddau troelli yn y deunyddiau hyn.

CH-127 Chemical Practice

This module will introduce students to the three broad employment areas for chemistry: research, teaching or industrial positions. The lecture portion will cover fundamental aspects of being a professional chemist including safety, report writing, project management, and teaching skills. Students will attend research seminars and workshops, industrial field trips, and supervise school pupils in the laboratory. Assessment will be by coursework and a written report.
CH-237 Further Physical Chemistry

This module will advance students¿ studies in Physical Chemistry. The module provides a more in-depth look at thermodynamics from both the classical and molecular viewpoints, the thermodynamics of mixing and chemical equilibrium. Electrochemistry is covered from a fundamental and applied view and serves is used to further discuss thermodynamics, non-ideal behaviour and equilibrium. A deeper look at kinetics is then included that builds on prior knowledge and highlights the importance of kinetics in chemical reactions and processes. The module will build on existing understanding, further developing mathematical skills to explore the material covered in this module. In the laboratory students will undertake more advanced investigative experiments to explore the physical concepts. Material, techniques and skills covered in the course of this module will build on and therefore require understanding of all prior modules. The module will be assessed by coursework (laboratory experiments, laboratory report and assignments) and by examination.
CH-342 Advanced Topics in Physical, Instrumental and Analytical Chemistry

This module completes the core aspects of Physical Chemistry for the undergraduate programme, applying existing understanding of thermodynamics and quantum mechanics to connect the quantum world with the observable world in Statistical Mechanics and relating quantum understanding to the application of light in chemical reactions. Laboratory experiments will be fully investigative, with students carrying out advanced `mini projects¿ to initiate and guide students in elementary research skills in preparation for their research projects. Material, techniques and skills covered in the course of this module will require understanding of prior modules.
CH-344 Chemistry Project

3rd year projects are the opportunity to bring all you've learnt during your degree together and apply that knowledge to solve a problem. In Swansea these projects can be embedded in active research groups across the colleges of science, engineering or medicine, allowing you to build a network and experience in your chosen specialism within the chemical sciences. These projects are your opportunity to demonstrate to employers that you have a full understanding of your course and are able to direct your own studies, manage an independent research project and effectively communicate your findings. This selection suggests an interest in a project embedded within a research group in engineering, focusing on materials chemistry or chemical engineering
CH-409 MChem Research Project

MChem projects are the defining feature of the integrated masters with a chance to contribute research work of potentially publishable standard to an active research group within the University. In Swansea these projects can be embedded in active research groups across the Faculty of Science and Engineering or the Faculty of Medicine, Health and Life Science, allowing you to build a network and experience in your chosen specialism within the chemical sciences. These projects are an excellent way of managing the transition on to your next destination after undergraduate study, whether that is a postgraduate research studentship or into employment. The skills developed in the MChem projects demonstrate the ability to successfully deliver all aspects of a 60 credit research project and on exit you will have demonstrated the academic equivalence and begun developing the other skills required for entry into professional development schemes leading to chartership. This selection suggests an interest in a project embedded within a research group in science, focusing on straight chemistry, or interacting and collaborating with another department such as bioscience, geography, physics, maths or computer science.
