Underground hydrogen storage has been recognized as a key technology for storing enormous amounts of hydrogen, thus aiding in the industrial-scale application economy. However, underground is only poorly understood, which leads to high project risk. This research examined effect caprock availability and injection rate on recovery factor leakage address some fundamental questions related storage...

Doping with other elements is one of the efficient ways to modify the physical and chemical properties of TiO2 nanomaterials. In the present work, anatase TiO2 nanofilms doped with Al and V elements were fabricated through anodic oxidation of Ti6Al4V alloy and further annealing treatment. Hydrogen sensing behavior of the crystallized Ti-Al-V-O nanofilms at various working temperatures was inves...

Basella alba fruit with dark blue skin and deep red violet flesh is a potential source of natural colorant. This study was aimed to evaluate the total betacyanin content, total phenol and to analyse the antioxidant activity against DPPH radical, superoxide anions, hydroxyl radical, metal chelating, hydrogen peroxide, FRAP, ABTS and deoxyribose degradation in a dose dependend manner. Betacyanin ...

this paper is a preliminary communication of a study on removal and recovery of heavy metalsfrom industrial waste waters using electro-coagulation (ec) technique. the larger study envisages use of solarenergy for producing the d.c. current, and simple chemical methods of standard methods in chemistry like useof hydrochloric acid, hydrogen sulfide, collection of precipitate, incineration and get...

The hydrogen production rate in a microbial electrolysis cell (MEC) using a non-buffered saline catholyte (NaCl) can be optimized through proper control of the initial anolyte pH and catholyte NaCl concentration. The highest hydrogen yield of 3.3 0.4 mol H2/mole acetate and gas production rate of 2.2 0.2 m H2/m/d were achieved here with an initial anolyte pH 1⁄4 9 and catholyte NaCl concentrati...

Anaerobic bacteria were isolated from industrial wastewater and soil samples and tested for exoelectrogenic activity by current production in double chambered microbial fuel cell (MFC), which was further transitioned into a single chambered microbial electrolytic cell to test hydrogen production by electrohydrogenesis. Of all the cultures, the isolate from industrial water sample showed the max...
