A new class of energetic nanoparticles, and a method to produce the same. The energetic nanoparticles are differentiated from other metallic energetic nanoparticles by their core-shell nanostructure including an intermediate boride layer that provides oxidation protection and acts as an active mass. An intermetallic reaction occurs between aluminum and nickel. Aluminum based nanoparticles were used for the examples, but the principle is applicable to other materials as well.

A negative electrode material for a lithium ion battery, in which a fine particle (A) containing an element selected from Si, Sn, Ge and In and a carbon particle (B) obtained by heat-treating a petroleum-based coke and/or a coal-based coke at a temperature of 2,500&#xb0; C. or more are connected through a chemical bond such as urethane bond, urea bond, siloxane bond and ester bond. Also disclosed are a negative electrode sheet obtained by coating a current collector with a paste containing the negative electrode material, a binder and a solvent, and then drying and pressure-forming the paste; and a lithium ion battery incorporating the negative electrode sheet.

A chromate-free, self-healing conversion coating solution for magnesium alloy substrates, composed of 10-20 wt. % Mg(NO)HO, 1-5 wt. % Al(NO)HO, and less than 1 wt. % of [VO]or VOdissolved in water. The corrosion resistance offered by the resulting coating is in several hundreds of hours in salt-spray testing. This prolonged corrosion protection is attributed to the creation of a unique structure and morphology of the conversion coating that serves as a barrier coating with self-healing properties. Hydroxoaluminates form the backbone of the barrier protection offered while the magnesium hydroxide domains facilitate the 'slow release' of vanadium compounds as self-healing moieties to defect sites, thus providing active corrosion protection.

Chemical conversion coating for protecting magnesium alloys from corrosion

Surface functionalized sorbent particles for vapor-phase mercury removal, especially in the presence of SOin, for example, flue gas. The sorbent surface is modified to increase the SOresistance of vapor-phase mercury sorbents. The mercury removal efficiency is immune to the presence of SO, which is not the case with conventional activated carbon as well as brominated activated carbons. The sorbent is based on carbon particles with a metal oxide coating on the surface. The thin metal oxide layer acts as an amenable surface to introduce functional groups. The metal oxide coated carbon was further modified with amine molecules, to increase its resistance towards SOpoisoning.

A new class of carbon-based sorbents for vapor-phase mercury removal is disclosed in this invention. The optimum structure of the sorbent particles, and a method to produce the sorbent, are described. The sorbent is based on carbon particles with a metal-oxide coating on the surface. The thin metal-oxide layer acts as a barrier for the adsorption of Air Entrainment Admixture (AEA), the component used to stabilize bubbles in cement), thereby enhancing its concrete friendliness. The metal-oxide is coated on the surface of carbon, using a solution-based method. The metal-oxide coated carbon was further modified with sulfur molecules, to increase its mercury removal capacity.

Environmentally benign sorbents for removing mercury from flue gas

A new class of sorbents for the removal of mercury from contaminated water. The optimum structure of the sorbent particles and a method to produce the same is described. The newly developed carbon-based particles are differentiated from other sorbent particles by their high accessible surface area and high affinity towards mercury ions that leads to faster and higher mercury adsorption. The sorbent is based on carbon particles with a metal-oxide coating on the surface. The metal-oxide is coated on the surface of carbon, using a solution-based method. The metal-oxide coated carbon was further modified with sulfur molecules, to increase its mercury removal capacity.

A method for producing nanostructured multi-component or doped oxide particles and the particles produced therein. The process includes the steps of (i) dissolving salts of cations, which are either dopants or components of the final oxide, in an organic solvent; (ii) adding a dispersion of nanoparticles of a single component oxide to the liquid solution; (iii) heating the liquid solution to facilitate diffusion of cations into the nanoparticles; (iv) separating the solids from the liquid solution; and (v) heat treating the solids either to form the desired crystal structure in case of multi-component oxide or to render the homogeneous distribution of dopant cation in the host oxide structure. The process produces nanocrystalline multi-component or doped oxide nanoparticles with a particle size of 5&#x2013;500 nm, more preferably 20&#x2013;100 nm; the collection of particles have an average secondary (or aggregate) particle size is in the range of 25&#x2013;2000 nm, preferably of less than 500 nm.
