Borates: a survey of main trends concerning crystal-chemistry, polymorphism and dehydration process of alkaline and pseudo-alkaline borates

A circuit device which enables easy formation of a connection part that connects wiring layers to each other, and a manufacturing method thereof are provided. In a method for manufacturing a hybrid integrated circuit device of the present invention, a first resin film is formed so as to cover a first wiring layer. Thereafter, a first through-hole is formed, which penetrates the first resin film and exposes the first wiring layer from a bottom thereof. Next, a second resin film is formed so as to fill up the first through-hole. Moreover, a second through-hole is formed in the second resin film buried in the first through-hole, and a connection part is formed.

Circuit device and manufacturing method thereof

Complex chemical hydrides can be used to store and deliver hydrogen gas to fuel cells, and thus are one of several candidate materials to be used in storage systems for the hydrogen economy. These hydrides have high native hydrogen content, and hydrogen can be released via several chemical pathways. This review summarizes the extensive literature on the kinetic and thermodynamic properties of the various reactions of chemical hydrides, with an emphasis on hydrolysis. These properties are significant because they affect all aspects of system design, as well as the recovery and recycle of the byproducts. Hydrolysis of chemical hydrides takes place at relatively low temperatures and gives promising theoretical hydrogen storage efficiencies. Complications include metastable kinetic pathways as well as inefficient utilization of water in the byproducts.
