Nanoparticulate gold film electrodes were prepared from oppositely charged gold nanoparticles (c.a. 6 nm diameter) by a layer-by-layer approach without application of linker molecules. This was done by alternative immersion of indium tin oxide plates

There is experimental evidence that in solutions of low ionic strength, charged nanoparticles (NPs) adsorbing onto an oppositely charged substrate cannot form dense monolayers due to the electrostatic repulsion. Here, we investigated the adsorption o

Deformable, spherical aggregates of metal nanoparticles connected by long-chain dithiol ligands self-assemble into nanostructured materials of macroscopic dimensions. These materials are plastic and moldable against arbitrarily shaped masters and can

Photoswelling of thin films of dichromated gelatin provides a basis for fabrication of multilevel surface reliefs via sequential UV illumination through different photomasks. The remarkable feature of this simple, benchtop technique is that by adjust

Carbanions of alkyl 2-phenylpropionates add to nitroarenes in positions para to the nitro group, the produced σ H adducts are oxidized by KMnO4 to form alkyl 2-phenyl-2-(4- nitroaryl)propionates whereas oxidation with dimethyldioxirane gives esters

Potassium and sodium salts of diphenylphosphine add to nitroarenes in the position ortho and para to the nitro group. Subsequent oxidation of σ H -adducts with potassium permanganate gave diphenyl(nitroaryl)phosphine oxides.

We present a new method to incorporate hydrophilic charged nanoparticles into the lyotropic liquid crystal (LLC) template. This method is based on the effect of the polymer-induced phase separation (PIPS) and consists of two steps. In the first step,

Electrostatic aggregation of oppositely charged silver and gold nanoparticles leads to the formation of core−shell clusters in which the shell is formed by the nanoparticles, which are in excess. Arguments based on Debye screening of interactions b
