The disclosure relates to embodiments of an explosive formulation comprising a detonable mixture of an oxidizing agent such as carbon dioxide, and a material that decomposes the oxidizing agent exothermically (a reducing agent), and additives that increase the mixture's shock sensitivity. The formulations may be used in a method to produce diamonds or nano oxides or in other applications that use traditional explosives such as, but not limited to: ammonium nitrate and fuel oil combinations (ANFO), watergel explosives, emulsion explosives and RDX.

Disclosed is a cathode active material for a lithium secondary battery including a core containing lithium composite metal oxide, and a coating layer disposed on the core and including an amorphous phase, wherein the amorphous phase contains lithium oxide and boron oxide in a form of mixture.

A reaction method comprising combining a carbonyl-substituted arylboronic acid or ester and an α-effect amine in aqueous solution at a temperature between about −5 C to 55 C, and a pH between 2 and 8 to produce an adduct. A process is also provided comprising: contacting a composition having a boron atom bonded to a sp.sup.2 hybridized carbon, the boron having at least one labile substituent, conjugated with a cis-carbonyl, with an α-effect amine, in an aqueous medium for a time sufficient to form an adduct, which may proceed to further products.

The extraction system contains secondary amides and alkyl alcohols which are separately used as the extractants for extracting lithium and boron and consist of a single compound or a mixture of two or more compounds, and the total number of carbon atoms in their molecules are 12˜18 and 8˜20 respectively; the extraction system has a freezing point less than 0° C. With a volume ratio of an organic phase and a brine phase being 1˜10:1, at a brine density of 1.25˜1.38 g/cm.sup.3, at a brine pH value of 0˜7 and at a temperature of 0˜50° C., a single-stage or multi-stage countercurrent extraction and a stripping are conducted to obtain a water phase with a low magnesium-lithium ratio, which is subjected to concentration, impurity removal and preparation to get lithium chloride, lithium carbonate, lithium hydroxide and boric acid respectively. Water is used for stripping, greatly reducing the consumption of acid and base.

The present invention relates to the process of purification of boric acid by ion exchange method. Boric acid is dissolved in hot demineralized water. The hot solution is pressure-filtered. The hot saturated solution, which is purified from water-insoluble, is passed through a column containing strong cation exchange resin, followed by a column containing weak anion exchange resin at the same temperature and cooled afterwards. The crystals settling by cooling are separated from the mother liquor, the amount of aqueous solution within them is reduced and then dried. The waste solution formed during crystallization and filtrate formed after separation of crystals from aqueous solution are mixed and used in boric acid dissolving process. The developed method enables the reduction of sodium, sulfate, chloride and iron impurities of technical grade boric acid to less than 1 ppm and is more economic and environmental friendly than current methods.

Provided are an atomic layer sheet that contains boron and oxygen as framework elements, is networked by nonequilibrium couplings having boron-boron bonds, and has a molar ratio of oxygen to boron (oxygen/boron) of less than 1.5, a laminated sheet containing a plurality of such atomic layer sheets and metal ions between ones of the sheets, and a thermotropic liquid crystal and a lyotropic liquid crystal containing these.
