Portrait of Dr Claudia H. Swanson

Dr. Claudia Swanson joined the Faculty of Science and Engineering at the University of Chester in September 2015. After studying chemistry at the University of Technology Clausthal, she continued her studies in Material Science and received a MSc from the University of California, Santa Cruz in 2008. She then graduated with a PhD in Chemistry and Biochemistry from the University of California, Santa Cruz in 2009.

Qualifications

Diplom-Chemiker, PhD, Member of MRS and RSC.

Research

Claudia’s research is in material science, she has two main research topics related to material science and also has interest in several smaller projects which can be wide spread such as analytical food chemistry.

Layered Double Hydroxides

Her main research project consists of the synthesis and examination of Layered Double Hydroxides, LDHs. The class of clay-like materials has broad applications such as a catalyst for organic reactions, for anion exchange and adsorption, in pharmaceutics and as additive for functional polymers. LDHs are of great interest as a green catalyst, being heterogeneous, inexpensive, non-toxic and reusable.

One interesting aspect of LDHs is that the material shows exfoliation properties. In already successfully published work, she examined the LDH of the formula Zn2Al(OH)6(NO3)·2H2O for its ability to exfoliate and interact with the polymer polyester. More recent experiments are centred towards biodegradable polymers.

Another interesting aspect of Layered Double Hydroxides is their ability to perform anion exchange. This property is of great interest for capturing unwanted anions from solution such as brines. Claudia’s research examines the iodine absorption properties for later application of iodine in repository waste applications.

Sintering of Rock Salt

Sodium chloride has been extensively studied for its behaviour when being sintered. A new approach is the utilization of rock salt. In the sinter process, the salt is getting heated just below its melting point, where the atoms are already starting to reassemble with evaporation and deposition mechanism. Rock salt consists of impurities like calcium sulfate, which gives very interesting results from pure sodium chloride. The sinter experiments are performed in partnership with the Federal Institute of Material Research and Testing (BAM) in Berlin.
