Reactions of ethanol on Ru(0001)

Surface reactions on metallic surfaces are important for applications as catalysis, fuel cells and capping layers for optics in extreme ultraviolet (EUV) lithography tools. For all these applications, insight in the mechanisms of adsorption and reactions of molecules on surfaces is critical for fundamental understanding, as well as for further development of new materials and processes for applications.

 

 

 

Electron attachment to a model peptide, N-methylformamide

Dissociative electron attachment (DEA) is an electron-induced fragmentation process, occurring at low energies (<15 eV), that is of interest to the fields of radiation chemistry, physics, radiation therapy, astrochemistry, and materials and surface science. N-methylformamide (HC(O)NHCH3, denoted as NMF), a simple amide containing the peptide linkage, mimics a possible scenario that could happen locally in peptides.

 

 

 

Challenges and prospects for developing CdS/CdTe substrate solar cells on Mo foils

Thin-film CdTe solar cells boast lab-scale efficiencies above 20% when designed in the 'superstrate configuration' whereby the transparent front electrode is deposited first, on a glass superstrate. By inverting the design so that the front electrode is deposited last (i.e. the 'substrate' configuration), the cells can be fabricated on lightweight, flexible metal foils, thereby widening the range of possible applications.

 

 

 

Chasing Stardust

The material density is remarkably variable in the space between the stars (the interstellar medium or ISM) with the densest regions consistent with good laboratory ultrahigh vacuum (UHV). Surprisingly, these dense regions are chemically the richest in space with more than 180 different types of molecules detected to date. However, detection of molecules does not tell us from where the molecules come or how important they might be! Astrochemistry addresses the first question while astrophysics tells us that certain small molecules, such as CO and H2O, are crucial for the formation of long-lived stars like our Sun.
