PCCP featured in Materials Today: Super fit enzymes

A PCCP paper on improving enzyme activity using nanoporous materials has featured in Materials Today this week.

The paper by Lung-Ching Sang and Marc-Olivier Coppens discusses how proteins adsorbed in nanoporous silica SBA-15 and propylated C3SBA-15 are perturbed to a different extent, leading to different enzymatic activity.

HOT article: Close-up on salt dissolving in water

Scientists from the UK and Italy have investigated what happens when salt dissolves in water. Using a computer simulation that follows the movement of the sodium and chloride molecules, the studies revealed that a complex multi-step process is triggered by the departure of chloride ions from the salt structure, with a well-defined intermediate state wherein departing ions are partially solvated but remain in contact with the crystal.

HOT article: Ionisation enhancement in ammonia

A team from the US has revealed the mechanism in which extreme ionisation of ammonia takes place. Ammonia’s ionisation properties play an important role in many applications ranging from planetary atmospheres to radiation chemistry and in the production of energetic materials.

Faraday Discussion 156: Tribology – call for oral abstracts

Faraday Discussion 156: Tribology
2 – 4 April 2012 
Southampton, UK

Deadline for Oral Abstracts: 3 June 2011 – submit now

Tribology is the essential science of all interacting surfaces in relative motion and affects our lives in many direct ways.

Tribology: FD156 will focus on advanced computational and experimental tribology, providing a forum for chemists, physicists, theoreticians, engineers and biomedical researchers within these themes:

  • Future lubricated systems 
  • Smart tribological surfaces 
  • Predictive modelling 
  • Biotribology       

Confirmed invited speakers:

  • Professor Duncan Dowson (Introductory) – University of Leeds, UK
  • Professor Nicholas Spencer (Closing) – ETH Zürich, Switzerland
  • Professor Jean-Michel Martin – Ecole Centrale De Lyon, France
  • Dr Ian Taylor – Shell Global Solutions, UK
  • Professor Jacob Klein – Weizmann Institute of Science, Israel
  • Dr Liliane Léger – NRS & Université Paris-Sud 11, France
  • Professor Pwt Evans – Cardiff University, UK
  • Professor Roland Larsson – Luleå University of Technology, Sweden
  • Professor John Fisher – University of Leeds, UK
  • Professor Greg Sawyer – University of Florida, USA

Faraday Discussions are a long-established series of meetings which provide a unique international platform for the exchange of views and newly acquired results in developing areas of physical chemistry, biophysical chemistry and chemical physics. The Discussion is a dynamic forum for developing and exchanging exciting new ideas, and both the papers and discussion will be published in a final printed volume.

We invite you to submit an abstract for an oral presentation by 3 June 2011. We do hope that this conference is of interest to you and that you will attend this exciting Faraday Discussion next year. 

Submit your oral abstract for Faraday Discussion 156: Tribology

Yuan Tseh Lee – EMRS Plenary Lecture

Yuan Tseh Lee, Nobel Prize Laureate and PCCP Honorary Board member, gave the first Plenary Lecture at the E-MRS today.

Professor Lee gave an inspiring lecture on the ‘Sustainable Development of Human Society.’

Yuan Tseh Lee

Professor Lee was the first Taiwanese to win the Nobel Prize – along with John Polanyi and Dudley R. Herschbach, they won the Nobel Prize in Chemistry in 1986 “for their contributions to the dynamics of chemical elementary processes.”
