The hydrogen compression that occurs in a metal hydride compressor is based on the chemical and thermal processes of absorption desorption into an intermetallic structure metals. concept presented this article centred use optimal alloy capable absorbing its at low temperature pressure. After such heated up, pressure will significantly increase, facilitates without it being direct contact with m...

Drives in belt conveyors are critical components of the conveyor system, susceptible to various factors that can cause disruptions and energy losses. In underground mining conditions, risk drive fires is particularly hazardous. Therefore, it necessary develop highly effective fire suppression systems. However, there no guidelines for designing such This study presents a methodology selecting ve...

Abstract As a promising energy storage device, the rechargeable Zinc-air fuel cells (ZAFCs) has attracted an increasing attention because of their high density, cost-effectiveness, non-toxic (in terms manufacturing materials cell as well products reactions), rich abundance zinc, compact system design, its environmental benignity. Rechargeable are investigated possible technology for fast respon...

Wet spinning was used to manufacture fibrous alginate hydrogel wound dressings. Samples manufactured using varied operating parameters (decreased air pressure and calcium concentration or increased nozzle diameter and alginate concentration) were compared with the control samples. The changes in the fiber size, Young's modulus, swelling ratio, fetal bovine serum (BSA) release efficacy, water va...
