Ethnobotanical studies were conducted among various tribes in different tribal districts of Orissa. It has been found that 6 plant species are used by the tribal people for preparation of Bakhar, which is generally used ...

We present our angle resolved photoelectron spectroscopy (ARPES) and density functional theory results on quaternary topological insulator (TI) BiSbTe1.25Se1.75 (BSTS) confirming the non- trivial topology of the surface ...

Understanding the energetics of electron transfer at the semiconductor interface is crucial for the development of solar harvesting technologies, including photovoltaics, photocatalysis, and solar fuel systems. However, ...

Nickel oxide in an Indian chromitiferous overburden was reduced with a CO-CO2-N-2 gas mixture and the effects of various operating parameters, such as roasting temperature, time and P-CO, Were studied. An extraction of ...

Recovery of metal value, especially from low-grade ores and overburden minerals using acidophilic bacteria through the process of bioleaching is an environmentally benign and commercially scalable biotechnology. In recent ...

Nickel losses have been observed from leach liquors obtained during extraction of metal values from ocean nodules using ammonium sulphite. Studies have been carried out to establish the reasons for such losses. Behaviour ...

A detailed study was made on cobalt losses during precipitation of manganese from the NH3-(NH4)(2)SO4-O-2 system. Various parameters were changed during this study: the concentration of ammonia and ammonium sulphate; oxygen ...

The study reports the effect of increasing pulp density on the bio-catalyzed leaching of metals from waste mobile phone printed circuit boards. Mixed microbial consortia of iron and sulfur-oxidizing microorganisms were ...

The unutilized iron ore fines (IOF, - 10 mm, 45% to < 60% Fe(T)) left at various mine sites during blasting and processing are rich in goethetic-hematite associated with high clay and considered a potential iron ore resource. ...
