Modules

CHY8423 : Research Challenges in Chemical Structure and Dynamics

Semesters
Semester 1 Credit Value: 10
ECTS Credits: 5.0

Aims

Contemporary physical chemistry makes important contributions to all areas of science. This module, which sets out to avoid mathematics, will highlight recent advances in four separate topics that each connect with important contemporary questions about chemical structure and dynamics; (A) Aerosols, (B) Astrochemistry, (C) Advanced Crystallography and (D) Time-Resolved Spectroscopy. Attention is given to modern aspects of the field and to the applications of research in these topics. Emphasis will be given to practical techniques without recourse to detailed mathematical approaches.

Aerosols (Section A) will play a significant role in the atmosphere, environment, combustion science and human health. This short course will discuss chemical and physical aerosol properties and key processes that affect their dynamics, kinetics and equilibrium state.

Astrochemistry (Section B) will explore the chemistry of the interstellar medium, interstellar clouds and circumstellar shells. The fundamental role of chemistry in the evolution of the universe will be discussed. The course examines both the physical chemistry that shapes the chemistry of the universe and the observational methods that allow its observation.

Advanced Crystallography (Section C) will discuss processes of crystal growth and the different methods used to obtain crystalline materials. This leads naturally to an advanced knowledge of the various analytical methods available to characterise crystalline materials. Attention will then be given to understanding some important relationships between the crystal structure of a solid and its physical or chemical properties. Examples of advanced materials will be used where the relationship between structure and function becomes evident.

Time-resolved Spectroscopy (Section D) will describe the experimental methods available for probing ultra-fast (femtosecond) chemical reactions and the motivations of these experiments. It will describe how researchers construct “molecular movies” that precisely follow the re-arrangement of molecular structures during chemical change. Such changes are understood and interpreted through quantum mechanics.

Teaching Rationale And Relationship

Students acquire knowledge and understanding through lectures and by the way of research articles available on the web. Handouts will provide additional knowledge. Students will undertake organised trips to research labs to see the various techniques in operation and will have opportunity to talk to specialists about these experimental protocols. Research articles will be discussed both formally and informally and used to illustrate the formal lectures. Students will be directed to key websites where additional information can be found in a more user-friendly manner than advanced textbooks.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The student will complete an essay on a subject they select from a list of topics relevant to the course. This task will require the student to read broadly around the topics explored during the course, draw connections to related themes and report on the outcomes of modern research. The second assessment task will require the student to give a presentation on a research topic whilst critically assess the achievements and constraints of different experimental approaches. The student will be marked on the depth of their knowledge and critical understanding of the subjects explored.

Study Abroad students may request to take their exam before the semester 1 exam period, in which case the format of the paper may differ from that shown in the MOF. Study Abroad students should contact the school to discuss this.
