An exemplary hydrogen production apparatus 100 according to the present invention includes a grinding unit 10 configured to grind a silicon chip or a silicon grinding scrap 1 to form silicon fine particles 2, and a hydrogen generator 70 configured to generate hydrogen by causing the silicon fine particles 2 to contact with as well as disperse in, or to contact with or dispersed in water or an aqueous solution. The hydrogen production apparatus 100 can achieve reliable production of a practically adequate amount of hydrogen from a start material of silicon chips or silicon grinding scraps that are ordinarily regarded as waste. The hydrogen production apparatus thus effectively utilizes the silicon chips or the silicon grinding scraps so as to contribute to environmental protection as well as to significant reduction in cost for production of hydrogen that is utilized as an energy source in the next generation.

Hydrogen being a clean, highly abundant and renewable fuel, is a promising alternative for conventional energy sources. Mostly, this hydrogen is stored in the form of hydrides. The existing methods for identification of material for hydrogen storage as expensive and time consuming. A method and system of identification of materials for hydrogen storage has been provided. The method provides a machine learning technique to predict the hydrogen storage capacity of materials, using only the compositional information of the compound. A random forest model used in the work was able to predict the gravimetric hydrogen storage capacities of intermetallic compounds. The method and system is also configured to predict the thermodynamic stability of the intermetallic compound.

The present invention provides a composition for prevention and/or improvement of encephalitis and/or meningitis. More specifically, the present invention provides a composition for prevention and/or improvement of encephalitis and/or meningitis and a symptom associated with the encephalitis and/or meningitis in a subject, comprising molecular hydrogen as an active ingredient.

A method for obtaining a mixture for producing H.sub.2, the mixture comprising a metal borohydride, Me(BH.sub.4).sub.n, a metal hydroxide, Me(OH).sub.n, and H.sub.2O, in which Me is a metal and n is the valance of the metal ion. The H.sub.2O is provided in ultrapure water, UPW, the UPW having an electrical conductance below 1 μS/cm. The method comprises dissolving the metal borohydride and the metal hydroxide in UPW to obtain the mixture for producing H.sub.2 comprising an amount of borohydride, BH.sub.4, groups of the metal borohydride in the range of 45 to 55% mol of the mixture, an amount of hydroxide, OH, groups of the metal hydroxide in the range of 2 to 5% mol of the mixture, and at least substantially UPW for the remainder of the mixture.

Dichlorosilane and trichlorosilane are dehydrogenated at elevated temperature in the presence of an ammonium or phosphonium salt as a catalyst, and a halogenated hydrocarbon or hydrogen halide. The method may be used to synthesize organochlorosilane.
