Heteropolyacids and their salts comprise catalytic centers for the production of ethylene, one most important constituents in chemical industry. The paper emphasizes different synthesis routes hybrid materials consisting dodecatungstophosphoric acid silver salt (AgPW) ? zeolite—stepwise wet impregnation, silver-exchange zeolite, dry mixing precursors. Composite preparation procedures induced mi...

A novel bandage inspired by gecko feet might one day be used during emergencies and internal surgeries. The bandage uses a combination of nanofabricated structures, biodegradable materials and adhesive surface chemistry that allows adhesion onto even wet, moving tissue.

Recent advances regarding the synthetic chemistry of fluorinated aziridines and azetidines are presented in this chapter. These small heterocycles are of high importance both as building blocks for more complex structures and as active parts of medicinal chemistry-oriented compounds. Methods are presented according to the precursors used for the synthesis.

This review reports the implementation of novel nanostructured functional coatings by using different surface engineering techniques based on wet chemistry. In the first section, the theoretical fundaments of three techniques such as sol-gel process, layer-by-layer (LbL) assembly and electrospinning will be briefly described. In the second section, selected applications in different potential f...

The formation of a hydroxylated native oxide layer on Si(001) under wet conditions is studied by means of first principles molecular dynamics simulations. Water molecules are found to adsorb and dissociate on the oxidised surface leading to rupture of Si-O bonds and producing reactive sites for attack by dissolved dioxygen or hydrogen peroxide molecules. Tensile strain is found to enhance the d...
