Communicating Chemistry Innovation to the Public
Full text linkThe thesis of this study is that communicating research achievements is an important component of research and technology management in chemistry research. New chemical products and new synthetic and analytical chemical processes often have a broad and lasting socioeconomic and environmental impact. Besides differentiating chemistry from other basic sciences, this trait is reinforced by the sustainability challenge to make economic growth compatible with long-term well-being for all people and the environment. Following a succinct review of previous scholarly work on chemistry communication, we identify the key benefits provided to chemistry scholars by the effective communication of chemistry innovation to the public
Enhancing Enzyme Stability for Biotechnological Applications
Full text linkEnzymes are emerging as a central element of green chemistry due to their high selectivity, biodegradability, and biocompatibility. However, their application in biotechnology is often limited by their poor stability under non-native conditions. Such an instability eventually compromises their catalytic efficiency and economic viability. To date, no single solution exists to universally solve the challenge of enzyme stability. Herein, we summarized the main strategies that have been developed to address this challenge, including enzyme discovery, protein engineering, enzyme immobilization, and computational tools. Beyond stability, this account also highlights recent technologies to improve biocatalytic efficiency. All these approaches are illustrated by examples of our most recent research work. Ultimately, enhancing enzyme stability and activity will have a broad impact for biocatalytic processes in biomedicine, food processing, and chemical manufacturing, among other biotechnology areas

Advanced Wastewater Treatment by Ozonation for Abatement of Micropollutants from Municipal Wastewater Effluents
Full text linkMunicipal wastewater treatment plants are important contributors to the discharge of micropollutants to the aquatic environment. Therefore, in Switzerland it has been decided to treat the water at these point sources to reduce the discharge of micropollutants from municipal wastewater effluents. A team of scientists at Eawag has evaluated treatment options, which need to be readily available, easily applicable, and cheap. Based on a rigorous assessment, activated carbon-based processes and ozonation were selected. In this paper the focus is on ozonation, and the different aspects of its application are discussed, including kinetics and mechanisms for ozone reactions with micropollutants and matrix components, formation, and fate of transformation products in biological post-filtration and toxicological aspects. Finally, upgrading of ozonation is described including outreach of this approach to other countries
