The study of hydrophobicity in water–methanol and water–tert-butanol mixtures

Molecular dynamics simulations have been performed for water–methanol and water–tertiary butyl alcohol mixtures in the water rich region. Nonlinear heat capacity and viscosity behavior as functions of concentration has been examined at the molecular level. The collective modes leading to enhancement of potential energy fluctuation and as consequence to heat capacity maximum has been found and discussed.     

Creation of silicon nanocrystals using the laser ablation in liquid

The method for the formation of silicon nanoparticles by picosecond laser pulses is studied upon the surface irradiation of the single-crystal silicon in various liquids. The ablation products are investigated using the atomic-force microscopy and Raman spectroscopy. The experimental results indicate the crystal-line structure of nanoparticles and the dependence of their size on the ablation medium.
