Dolenni Ymchwil

Trosolwg

Astudiodd GA ffiseg (BSc ac MSc Hebrew University, PhD - Prifysgol Caergrawnt) ac mae wedi treulio'r rhan fwyaf o'i yrfa yn cyflawni gwaith ymchwil ar y rhyngwyneb rhwng cemeg a ffiseg, gan astudio dynameg arwyneb a rhyngweithiadau arwyneb nwy.

Agwedd gyffredin ar waith ymchwil GA yw canolbwyntio ar gwestiynau ymchwil sy'n amhosibl eu hastudio gan ddefnyddio technoleg wyddonol sy'n bodoli, ond y gellir mynd i'r afael â nhw trwy ddylunio, adeiladu a chymhwyso technegau arbrofol newydd.

Mae uchafbwyntiau ymchwil penodol yng ngyrfa GA yn cynnwys y mesur delwedd 2D Fourier-ESR cyntaf [Phys. Rev. Lett. 84, 2973], datblygu dyfais MRI bychan [Patent UDA, 6,377,048], astudiaethau atsain sbiniau heliwm arloesol o fudiant arwyneb [Phys. Rev. Lett. 15, 156103 & Science 304, 1790], gwahanu moleciwlau dŵr ortho a para yn llwyddiannus [Science, 331, 319] a datblygu techneg newydd sy’n gallu rheoli a mesur cyflyrau cwantwm cylchdroadol moleciwlau cyflwr isaf [Nature Communications, 8, 15357 (2017), Nature Communications. 11, 3110 (2020).]

Uchafbwyntiau Gyrfa

Ymchwil

Rheoli cyflwr cwantwm cylchdroadol moleciwlau. Pan fydd moleciwl yn gwrthdaro ag arwyneb, mae sawl canlyniad gwahanol posibl. Yn benodol, gall wasgaru yn ôl i’r gwedd nwy, gall lynu wrth yr arwyneb a gall ddatgysylltu adeg y gwrthdrawiad. Mae deall y prosesau hyn yn gam hanfodol i ddeall cemeg arwyneb yn gyffredinol a chatalysis heterogenaidd yn arbennig. Un o’r nodweddion sy’n effeithio ar ganlyniad y gwrthdrawiad yw cyflwr taflunio cwantwm cylchdro y moleciwl (sy’n cyd-fynd â chyfeiriad plân cylchdroi y moleciwl mewn perthynas â’r arwyneb). Nid oedd modd rheoli na mesur y nodwedd gwantwm hon ar gyfer y rhan fwyaf o foleciwlau. Mae ein grŵp wedi datblygu techneg arbrofol newydd sy’n gallu rheoli a mesur cylchdro moleciwlau hydrogen cyflwr isaf, gan roi dealltwriaeth newydd o ryngweithiad moleciwlau gydag arwynebau [Nature Communications, 8, 15357 (2017), Nature Communications. 11, 3110 (2020).

Gwahanu H2O Ortho a Para. Mae moleciwlau dŵr yn bodoli fel dau sbin-isomer gwahanol, a’r gwahaniaeth rhyngddynt yw eu cyflwr sbin niwclear, sy’n debyg i’r achos adnabyddus o hydrogen moleciwlaidd ortho a para. Yn wahanol i hydrogen, roedd hi’n amhosibl gwahanu H2O Ortho a Para. O ganlyniad, prin yw’r wybodaeth sydd gennym ac nid oes cymwysiadau sy’n gallu ymelwa ar eu nodweddion ffisegol gwahanol. Trwy ddefnyddio dull gwahanu â magnetau, llwyddwyd i wahanu’r ddau, gan gynhyrchu paladr moleciwlaidd hynod bur o Ortho-H2O. Mae ein grŵp yn ceisio canfod cymwysiadau newydd sy’n defnyddio’r arloesedd technegol hwn.

CH-124 Structure and Bonding 2

Building on Structure and Bonding 1 (CH-123), this will extend the theoretical underpinning for atomic and molecular structure and will address more advanced examples from organic and inorganic chemistry as well as macroscopic systems. The content of this module will require knowledge developed in prior modules as well as independent reading outside scheduled sessions. The module will have a variety of formative assessment opportunities and summative assessments that include writing of technical reports, a presentation, quizzes, workshops, and an exam.
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-240 Computational and Theoretical Chemistry

The area of computational chemistry is of ever increasing importance in industry; from designer materials to prediction of likely drug targets, the falling cost of computational power is allowing the simulation of ever more complex molecular systems, lowering the cost of real-world research. This module will take the foundations of theoretical chemistry covered in Year One and further develop these in order to apply to in silico chemistry. Note: it is expected that material, techniques and skills covered in the course of this module will require understanding of any prior core module.
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.
CH-412 Advanced Integrated Topics in Chemistry Part 1

This module gives students the opportunity to explore options within Chemistry, giving opportunity to apply prior learning to advanced research topics and allowing students to pursue more specialised topics related to their research interests and aligned with the research areas represented within the Department. Study areas available will include advanced spectroscopic techniques, the application of instrumentation in chemistry, as well as more advanced synthetic pathways and a return to more integrated study of the traditional branches of organic/inorganic/physical chemistry. Classes will be supported with workshops which will help students gain a thorough understanding of the integrated nature of Chemistry at an advanced level. Where possible, topics will be taught using relevant examples from primary literature, encouraging students to evaluate and appraise a range of primary literature sources and locate appropriate new sources. The module is designed to be flexible to allow the content to vary with the research areas represented within the Department.
