Worldwide, hydrogen is gaining ground since it a promising alternative energy source to conventional fuels, which include fossil fuel. Thus, numerous techniques generate have been suggested. This literature review describes the challenges and obstacles identified through series of publications that target hydrolysis sodium borohydride. present several catalysts reactor systems for generation ga...

Aminoalkylalkoxysilane copolymers (co-AAAS) have the ability to simultaneously deacidify and strengthen paper documents. Nevertheless, despite enhancing tensile strength, they generally fail improve folding endurance of degraded groundwood pulp-rich papers. Focusing on that specific type papers, several ways overcome their lack reinforcement were investigated. Promoting polymerization AAAS usin...

In 1941 (1) the senior author entered the field of 16-substituted steroids with the view of preparing all of the three possible 16,17-epimers of natural estriol. Since that time two of these three epimers, 16-epiestriol (isoestriol-A) (2) and 17-epiestriol (3), have become available through our efforts and those of the Swiss investigators. In 1952 the present authors made an attempt to prepare ...

Aryl-substituted olefins react with t-butyl nitrite and sodium borohydride in the presence of iron(ii)phthalocyanine to give oximes in moderate to high yields.
