Trosolwg

Mae fy mhrif ddiddordeb ymchwil mewn cemeg arwynebau, deunyddiau, polymerau, a choloidau a hefyd o ran datblygu a deall y gydberthynas rhwng y strwythurau a fabwysiadwyd gan wlychwyr/ gwlychwyr polymerig ar ryngwynebau a phriodweddau ffisegol y deunyddiau hyn mewn toddiannau. Bydd gan ddeunyddiau o'r fath ystod eang o ddefnyddiau ac fe'u defnyddir yn helaeth, o adferiad olew uwch (EOR) a fformwleiddiadau gofal personol i gyfryngau trosglwyddo cyffuriau.

Mae fy ngwaith presennol yn y Sefydliad Ymchwil Diogelwch Ynni (ESRI) yn canolbwyntio'n bennaf ar gemeg materol, ymarferoliad/synthesis nanoronynnau a microronynnau.

EGCM02 MSc Research Practice

This Masters-level course equips students with the knowledge and skills necessary to structure and write scientific papers and reports of journal quality. Students will prepare multiple reports, each focusing on specific aspects of drafting a publication. The course involves gathering research data, performing suitable data analysis, and utilising the results to write draft publications. Key components of the course include: 1) Laboratory-based work to collect data 2) Rigorous and appropriate data analysis 3) Manuscript preparation to present results effectively To ensure continuous learning and improvement, the course is structured with multiple smaller assignments leading up to a scientific report in the form of a draft publication. This incremental approach allows students to progressively refine their writing and skills over the duration of the course.
EGCM30 MSc Dissertation - Chemical Engineering

The EGCM30 research project is the major item of directed independent learning undertaken during the master¿s programme and will normally be carried out on a research topic proposed by a member of staff from the Faculty of Science & Engineering. Study for the dissertation, which may be based on practical, industrial, simulation or literature work, or any combination of these, is carried out over a period of about 12 weeks, with the dissertation submitted at the end of September.
EGDM01 Colloid and Interface Science

Students will gain an in-depth understanding of the properties of colloids and their importance in industry.
