Trosolwg

Cwblhaodd Dr Helen Chadwick ei Gradd Meistr mewn Cemeg ym Mhrifysgol Rhydychen yn 2008, a chwblhaodd ei Doethuriaeth mewn Cemeg Ffisegol yn 2012. Derbyniodd wobr ddoethurol EPSRC i barhau â’i gwaith ymchwil fel myfyriwr ôl-ddoethurol yn Rhydychen, cyn symud i’r EPFL yn y Swistir yn 2013 i gynnal arbrofion deinameg arwynebau nwy. Ar ddiwedd 2016, enillodd Dr Chadwick Gymrodoriaeth Symudedd Ôl-ddoethurol Uwch o’r Swiss National Science Foundation i dreulio dwy flynedd yn y grŵp Cemeg Damcaniaethol ym Mhrifysgol Leiden yn yr Iseldiroedd, gan gyflawni cyfrifiadau i gael darlun cliriach o’r arbrofion a wnaeth yn yr EPFL. Ymunodd Dr Chadwick â’r grŵp Deinameg Arwynebau ym Mhrifysgol Abertawe fel Swyddog Ymchwil (uwch ôl-ddoethurol) ym mis Chwefror 2019, a’i phrif ffocws yno yw datblygu dulliau dadansoddi a fydd yn cael eu defnyddio i ddehongli data a fesurir gan ddefnyddio’r ymyradur pelydrau moleciwlaidd unigryw sydd yn yr Adran Gemeg.

Ymchwil

Yn ddiweddar, mae’r grŵp Deinameg Arwynebau wedi datblygu techneg triniaeth fagnetig newydd sy’n ein galluogi i reoli cyflyrau taflunio troelliadau cylchdroadol a niwclear moleciwlau cyflwr sylfaenol. Mae ffocws fy ngwaith ymchwil ar ddatblygu’r dechneg hon er mwyn ateb cwestiynau sylfaenol nad oedd yn bosibl gyda dulliau o’r radd flaenaf blaenorol ar gyfer moleciwlau cyflwr sylfaenol, gan gynnwys.

Sut mae cyfeiriadedd cylchdroadol moleciwl (h.y. boed yn cylchdroi fel hofrennydd neu olwyndroi) yn effeithio ar ganlyniad y gwrthdrawiad â’r arwyneb?

A ellir rheoli cyfraddau ymateb drwy newid cyfeiriadedd cylchdroadol moleciwlau sydd yn y cyflwr nwy?

A all gwrthdrawiad unigol ag arwyneb arwain at naill ai fflip troelliad niwclear neu drawsnewidiad troelliad niwclear yn y moleciwl?

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, presentation and assignments) and by examination.
CH-241 Analytical Chemistry

This course will cover theory and applications of qualitative and quantitative analytical chemistry, with particular emphasis on quantitative chemical analysis. The students will learn about various processes and measurements involved in a chemical analysis, and about statistical analyses of the data acquired during such experiments. The topics related to both classic (e.g., titrations) and modern analytical techniques (e.g., spectroscopy, surface analysis) will be covered. 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 (a presentation, laboratory experiments, laboratory report and assignments) and by examination.
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.
