About

Emrys Evans studied Chemistry at the University of Oxford (MChem 2012; DPhil 2016, supervised by Professor Christiane Timmel). His PhD project was on the photo and spin physics of light-induced radical pairs implicated in magnetoreception for animal navigation. Following this he worked with Professor Sir Richard Friend at the Cavendish Laboratory, University of Cambridge as a Research Associate (2016-2019) and Leverhulme Trust Early Career Fellow (2019-2020). At Cambridge he conducted research on organic semiconductors and radical materials for optoelectronics in collaboration with Professor Feng Li, Jilin University. In 2020 he was awarded a Royal Society University Research Fellowship to lead research at Swansea University on ‘Radical energy and spin control in organic electronics.’ In 2021 he was awarded a Dillwyn Medal for STEMM from the Learned Society of Wales in recognition of early career research excellence for his work in the field of optoelectronics. In 2022 he received a Swansea University Research & Innovation Rising Star award.

Career Highlights

Research

Radicals have unpaired electrons, leading to unusual chemistry and physics that could be used in next-generation organic electronics and molecular-based technologies. Emrys’s research explores novel functionality that arises from luminescence, magnetism and spin properties in these materials.

Taught Modules

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.
SC-M03 Processable Electronics

Since the 1970s, plastic electronics has expanded into a multitude of technologies and products incorporating flexible and transparent electronic circuits. Polymers or inks can be used as printable inks onto polymer-based substrates using various printing technologies, spin coating or vacuum deposition. Plastic electronics can use printed inks on plastic substrates, or it can consist of organic conductive polymers. Applications of plastic electronics will be discussed.
