A combination of immiscible molecules in the ligand shell of a gold nanoparticle (NP) has been shown to phase separate into a rippled structure; this phase separation can be used to direct the assembly of the NPs into chains. Here we demonstrate that only ...
The functionalization of nanoparticles is conditio sine qua non in studies of specific interaction with a biological target. Often, their biological functionality is achieved by covalent binding of bioactive molecules on a preexisting single surface coatin ...
The chemical and electrochemical promotion of highly dispersed nanofilm Rh catalysts (dispersion: about 10 %, film thickness: 40 nm) has been investigated for the first time. To this end Rh metal was sputter-deposited, either on a purely ionic conductor (8 ...
Using a density functional approach, we study structural and magnetic properties of small Fe-n clusters (nless than or equal to8) deposited on a MgO(100) substrate. Upon deposition, the clusters closely preserve their gas-phase structure. The magnetic mome ...
The :T-stacking of oxidized thiophene oligomers is investigated using extensive ab initio quantum chemistry methods. Dimers of singly charged oligothiophenes are unstable in the gas phase but can be stabilized as bound dications in the singlet state by a p ...
Recently we reported on the synthesis and characterization of a series of very weakly coordinating anions (WCA's) of type Al(OR)4- (R=poly or perfluorinated aliph. alkoxide). These anions produce "Pseudo Gas Phase Conditions" in the solid state that allo ...
A review. This review addresses the catalytic reactions performed in microstructured reactors, which are more and more recognized in recent years as a novel approach for chem. and chem. process industry. They are particularly suited for highly exothermic a ...
A review on isolated cationic and neutral homoat. heavier group 15 cages and clusters, charged or non-charged assemblies of two or more elemental atoms E (E = P, As, Sb, Bi) without stabilizing (bulky) ligands. It focuses on the recent developments in the ...
We have studied a model of a complex fluid consisting of particles interacting through a hard-core and short-range attractive potential of both Yukawa and square-well form. Using a hybrid method, including a self-consistent and quite accurate approximation ...
Many of the complex physical processes relevant for compositional multi-phase flow in porous media are well understood at the pore-scale level. In order to study CO2 storage in sub-surface formations, however, it is not feasible to perform simulations at t ...
