Ni-based catalysts supported on alumina derived from the pseudo-boehmite prepared by impregnation method were employed for catalytic dry reforming of methane reaction at temperature 550–750 °C. The effect calcination physicochemical properties such as Ni dispersion, reduction degree, nickel crystallite sizes, and metal–support interaction was investigated. characterization results show that inc...

Yellowstone Lake hydrothermal vent systems have been studied using ROV assets to better understand the chemical and mineralogical evolution of sublacustrine sediments through which hot spring fluids discharge lake floor. Here we focus on deposits/alteration coexisting fluid chemistry associated with Deep Hole floor, east Stevenson Island. Remote in its location, at 120 m below surface, this reg...
