This invention in one aspect relates to a method of synthesizing a self-assembled mixed-dimensional heterostructure including 2D metallic borophene and 1D semiconducting armchair-oriented graphene nanoribbons (aGNRs). The method includes depositing boron on a substrate to grow borophene thereon at a substrate temperature in an ultrahigh vacuum (UHV) chamber; sequentially depositing 4,4-dibromo-p-terphenyl on the borophene grown substrate at room temperature in the UHV chamber to form a composite structure; and controlling multi-step on-surface coupling reactions of the composite structure to self-assemble a borophene/graphene nanoribbon mixed-dimensional heterostructure. The borophene/aGNR lateral heterointerfaces are structurally and electronically abrupt, thus demonstrating atomically well-defined metal-semiconductor heterojunctions.

Described are gas storage medium and methods of storing source gases in the gas storage medium, particularly relating to using hydroxylated metal oxides or hydroxylated metalloid oxides as a storage medium for storing diborane.

The present disclosure relates to a method for processing a liquid by-product of sodium borohydride hydrolysis to obtain a borate compound, the method comprising the following steps: separating the liquid by-product by sedimentation, to obtain a borate-rich supernatant; drying the borate-rich supernatant under vacuum to obtain a solid composition comprising a borate compound. An aspect of the present disclosure relates composition obtainable by the disclosed method comprising at least 90% (w/w) of sodium boron hydroxide and its use as a source of borate in the production of sodium borohydride and/or hydrogen.

An apparatus includes a boiler configured to receive water, sodium hydroxide, and aluminum; a generator adjacent to the boiler and configured to generate electricity based on heat received from the boiler; a transformer electrically coupled with the generator; a hydrogen capture system coupled with the boiler and configured to capture hydrogen from the boiler; a carbon capture system coupled with the hydrogen capture system to produce hydrocarbons on-site; a nitrogen capture system coupled with the hydrogen capture system to produce ammonia on-site; and a boron 11 containment system coupled with the hydrogen capture system to produce hydrogen boron on-site.
