Abstract: The present invention is directed to a flowable mixture including: a) a hydrated clay suspension and b) sulfur derived from elemental sulfur. Preferably, the flowable mixture includes elemental sulfur particles and a hydrated, absorbent clay, such as bentonite clay. The flowable mixture is preferably a liquid mixture for use as a fertilizer or fungicide.
Abstract: A conductive nanowire film based on a high aspect-ratio metal is disclosed. The nanowire film is produced by inducing metal reduction in a concentrated surfactant solution containing metal precursor ions, a surfactant and a reducing agent. The metal nanostructures demonstrate utility in a great variety of applications.

Abstract: Aqueous dispersion containing a metal oxide powder with a fine fraction and a coarse fraction, in which—the metal oxide powder is silicon dioxide, aluminum oxide, titanium dioxide, zirconium dioxide, cerium oxide or a mixed oxide of two or more of the aforementioned metal oxides,—the fine fraction is present in aggregated form and has a mean aggregate diameter in the dispersion of less than 200 nm,—the coarse fraction consists of particles with a mean diameter of 1 to 20 ?m, —the ratio of fine fraction to coarse fraction is 2:98 to 30:70, and—the content of metal oxide powder is 50 to 85 wt. %, referred to the total amount of the dispersion. The aqueous dispersion is produced by a process comprising the steps:—production of a fine fraction dispersion by dispersing the pulverulent fine fraction in water by means of an energy input of at least 200 KJ/m3?, and—introducing the coarse fraction in the form of a powder into the fine fraction dispersion under dispersing conditions at a low energy input.

Abstract: Methods for manufacturing nanomaterial dispersions, such as nanomaterial concentrates, and related nanotechnology are provided. The nanomaterial concentrates provided can be more cheaply stored and transported compared to non-concentrate nanomaterial forms.
Abstract: A doped-type metal sulfide phosphor nanoparticle dispersion, comprising a doped-type metal sulfide phosphor nanoparticle dispersed in a hydrophobic organic solvent, wherein the doped-type metal sulfide phosphor nanoparticle comprises a surface that is modified with a surface modifier, the surface modifier being a compound represented by formula [I]: HS-L-WFormula [I] wherein L represents a divalent linking group; and W represents COOM or NH2, in which M represents a hydrogen atom, an alkali metal atom, or NX4, in which X represents a hydrogen atom or an alkyl group.
Abstract: The invention relates to a metal sulfide dispersion used for electroplating nonconductors such as substrates used for the formation of a printed circuit board. A printed circuit board made using the dispersion could have metallized through-holes comprising electrodeposited copper on the walls of the holes with an adsorbed layer of metal sulfide particles between the circuit board base material and the copper on the walls of the through-holes. The metal sulfide is characterized by spherical particles having a mean diameter of less than 100 nanometers and a particle size distribution where less than 10 percent of the particles within the dispersion have a diameter twice that of the mean diameter of all particles within the dispersion.
