The search for and exploitation of efficient catalytic systems for selective conversion of furfural into various high value-added chemicals remains a huge challenge for green synthesis in the chemical industry. Here, novel Pt nanoparticles supported on bamboo shoot-derived porous heteroatom doped carbon materials were designed as highly active catalysts for controlled hydrogenation of furfural ...

The developed new variational method for measuring the permittivity ξ' and dielectric losses ξ'' of polar liquids is free from a number shortcomings. At which minimum amplitude reflected wave (ρ) or standing coefficient η takes place, value ηm at this liquid thickness based on layer in cell. A variant was considered assumption active initial resistance waveguide section with corresponding to η,...

Jasmonates, derivatives of jasmonic acid, are lipid-derived oxylipins with cyclopentanone ring, produced as a result dioxygenation mediated by lipoxygenases. The biosynthesis acid is catalysed series different enzymes, starting from lipoxygenase, allene oxide synthase, cyclase and 12-oxophytodienoic reductase to the final three rounds β-oxidation. Consequently, few metabolites known jasmonates ...
