Disclosed is a method of irradiating a composition having water and hydrogen-terminated nanodiamonds with light that generates water-solvated electrons from the nanodiamonds. The method can be used to degrade fluoroalkyl compounds such as perfluorooctane sulfonate.

Nanodiamond reduction photochemistry

Cyanophosphines other than P(CN)react with lithium dicyanamide to produce lithiated carbon phosphonitrides with mobile Liions.

Lithium conducting carbon phosphonitrides from substituted cyanophosphine

Carbon phosphonitride (CPN) including tricyanophosphine (P(CN)), its pre-polymer (CPN-PP), and/or solid CPN(CNP) can serve as a useful additive for thermoset resins, resulting in improved thermal and mechanical properties.

Carbon phosphonitride polymer additives

A method of preparing borosulfate materials avoids the need for fuming sulfuric acid, also known as oleum. Instead, B(OH)present in solution in concentrated sulfuric acid at 5% to 15% by weight is reacted with a cation source at 100-250° C. under dynamic vacuum while in connection with a receiving vessel comprising a desiccant and separate from the reaction vessel, thereby causing formation of a borosulfate material in the reaction vessel while eliminated water is collected in the receiving vessel.

Scalable method for preparing crystalline borosulfate materials

Deposition of Pt nanoparticles on UiO metal organic frameworks via solvothermal reduction is achieved by reducing Pt acetylacetonate (Pt(acac)) in a UiO-66 and N,N-dimethylformamide (DMF) mixture at, for example, 130° C. for 18 hrs. Modification of reaction temperature and time can control the size of the Pt nanoparticles.

Platinum nanoparticle deposition on a series of UiO metal-organic frameworks

A nanoparticle of a decomposition product of a transition metal aluminum hydride compound, a transition metal borohydride compound, or a transition metal gallium hydride compound. A process of: reacting a transition metal salt with an aluminum hydride compound, a borohydride compound, or a gallium hydride compound to produce one or more of the nanoparticles. The reaction occurs in solution while being sonicated at a temperature at which the metal hydride compound decomposes. A process of: reacting a nanoparticle with a compound containing at least two hydroxyl groups to form a coating having multi-dentate metal-alkoxides.

Substituted cyanophosphine additives for lithium conducting carbon phosphonitrides

Described herein is the preparation of carbon phosphonitride pre-polymers that are soluble in organic solvents and can be further thermoset into carbon phosphonitride extended solids (i.e. films, monoliths, etc.) with an approximate empirical formula of CNP.

Organic solvent processable carbon phosphonitride pre-polymers

Borosulfate salts of protic Br&#xf8;nsted bases, for example NH[B(SO)], can serve as proton conductors in electrochemical devices such as fuel cells, flow batteries, and electrolyzers.

Borosulfate proton conducting materials

A lithiated carbon phosphonitride material is made by, for example, reacting P(CN)with LiN(CN)in solution (for example, dimethoxyethane or pyridine), then drying the solution to obtain the product. The material is a thermoset that is stable to over 400&#xb0; C. and exhibits up to 10S&#xb7;cm2 of Liconductivity.

A transition metal amino borohydride material includes a first row transition metal in conjunction with an amine ligand and borohydride, in a condition of having been thermally treated to a temperature of at least 70&#xb0; C. and up to but not including 800&#xb0; C. An exemplary such material, Fe(DETA)(BH)having been heat treated at 300&#xb0; C., had good hydrogen storage characteristics.
