Non-uniform flow structure behind a dusty gas shock wave with unsteady drag force
One of the important subjects of high-speed gasdynamics is the two phase flows of gaseous media loaded with small solid particles (dusty gases). The research field is directly linked to many important applicat...

The effect of an unsteady drag force on the structure of a non-equilibrium region behind a shock wave in a gas-particle mixture
For numerical analysis of shock wave propagation in gas-particle mixtures, drag coefficients of a sphere in steady flows are generally used. However, it is shown both experimentally and numerically that a shoc...

High-temperature ultrafast polariton parametric amplification in semiconductor microcavities
Cavity polaritons, the elementary optical excitations of semiconductor microcavities, may be understood as a superposition of excitons and cavity photons1. Owing to their composite nature, these bosonic particles...

Bifunctional copper catalysts. Part II. Stereoselective synthesis of (-)-menthol starting from (+)-citronellal
The one-step transformation of (+)-citronellal into (-)-menthol has been realised with yield ∼90% and stereoselectivity up to 80% under mild conditions in the presence of Cu/SiO2 by exploiting the presence of aci...
