The Bayer red mud generated from the alumina industry is a hazardous solid waste. In our team, a green calcification–carbonation process is proposed for its disposal. Red mud is treated with lime to convert the silicon phase in solution into hydrog

A one-step double emulsification protocol using sodium caseinate (SC) and xanthan gum (XG) mixture was developed for water-in-oil-in-water (W/O/W) double emulsions. Effect of pH on the stability of these emulsions has also been studied. The study of

Dimethyl ether (DME) is considered as a substitution of diesel oil. It can be used in diesel engines because of its high cetane number (> 55). The combustion process does not generate particle matter (PM) or sulphur oxides (SOx) pollutions. One of th

Direct synthesis of H2O2 from H2 and O2 can avoid the energy and environmental problems of current multi-step anthraquinone oxidation process by enabling high atom utilization and generating only a water by-product. However, the direct process suffer

Physical Review A
Charge transfer processes between weakly bound entities play an important role in various chemical and biological environments. In this combined experimental and theoretical work, we investigate the nature of charge-transfer processes in homogeneous
