Chiral gemini surfactants containing stereogenic centers and two amphiphilic moieties, not only maintain the chiral properties, but also exhibit stronger aggregation properties,...

Membranes of cells are the physical barrier between the inside and outside of the cell. Transport and signaling is control by transport and signaling proteins but their ability...

Interface effects are attracting a renewed interest in recent years. It resides in the fact that when an interface is formed the break of symmetry gives rise to entirely new...

Plant-derived biosurfactants of the group of saponins offer an attractive alternative to synthetic surfactants because of their unique foaming and emulsifying properties...

The yeast Candida glabrata is becoming an increasing cause of infections. We have developed RNA interference tools that allow us to study the virulence and resistance mechanisms...

The gram-negative bacterial membrane is of extreme medical importance. Two of its major components are lipopolysaccharides (LPS's) and integral membrane proteins. Porins are...

Polyoxometallates (POM) are well defined transition metal clusters with a range of interesting catalytic, magnetic and optical properties. To make efficient use of these...

Oxidation of atmospheric aerosol can produce cloud condensation nuclei capable of changing the reflectivity and lifetime of clouds. The oxidation of organic film on atmospheric...

In a soft magnetic material the directions of the internal magnetic moments are easily changed by an external magnetic field while in a hard magnetic material they are not. In a...
