A colloidal brewing system has a transparent container assembly with a watertight bottom portion and an open top portion, the container assembly adapted to contain water. A removable lid electronic housing with two replaceable electrically charged silver rod members is disposed on a bottom portion of the lid member, the rod members extending substantially to near the bottom of the container assembly. A magnetic stir assembly substantially centers an interior bottom portion of the container assembly and to rotate, in the water, on a parallel plane to the bottom portion. A receiver and transmitter coil assembly are disposed within a base container assembly, the base container assembly designed to gravitationally support the watertight bottom portion of the transparent container assembly, the receiver coil and transmitter coil assembly inductively coupled to the magnetic stir assembly. The inventive concept has a rechargeable battery, a control panel, power port members, and handle member.

Methods for preparing highly stable concentrated dispersions of silver nanoparticles and described herein. Contemplated methods comprise combining a selected polysaccharidic dispersant with a selected non-reacting dispersant to yield concentrated silver dispersions with enhanced stability and lowered undesirable residual organics. Contemplated methods further comprise selecting an appropriate source of silver ions to reduce the ionic strength of the reaction medium and final silver dispersions.

The present invention relates to a combustion additive comprising a colloidal solution containing dispersed fine metal particles. The present invention also relates to a method for producing the colloid. More particularly the present teaching relates to a combustion additive having a colloid, wherein the colloid comprises metal particles providing in an alkaline aqueous solution, the metal particles being dispersed within that solution and having an average diameter in the range of 30 nm to 30 μm. The colloid can partly/fully substitute water of a water injection system or used as an air humidification component for combustion.

A process for producing doped nanoparticles, in particular for N-doped nanoparticles, includes a hydrothermal process using an organic nitrogen-containing compound or a mineral acid having at least one nitrogen atom. In particular, the photocatalytically active particles produced are characterized by a particularly high activity even in visible light.

Colloids comprising inorganic nanocrystals dispersed in a molten salt or a liquid metal are provided. The molten salt may comprise an ion which is a Lewis acid or a Lewis base in the presence of the inorganic nanocrystals. Solid composites formed from the colloids are also provided. Methods of using the colloids as media for inducing chemical transformations using the inorganic nanocrystals are also provided.

Methods and systems for manufacturing a mixed-metal part by preparing a mixed-metal sol-gel as a feed material and using an additive manufacturing technique to form the mixed-metal part from the mixed-metal sol-gel feed material.

The invention relates to an apparatus and methods for producing liquid colloids such as suspensions of nanoparticles, in which liquid feedstock materials are reacted on a reaction surface of a rotatable plate. The apparatus has a first plate (101) mounted for rotation about a rotation axis (102), the first plate (101) providing a reaction surface (103) having a concave portion; first (106) and second (107) inlet lines arranged to introduce respective first and second liquid feedstock materials to the reaction surface (103); and a collection unit (110) arranged to collect a reaction product formed from reaction of the liquid feedstock materials as a liquid colloid ejected from an outer edge of the plate (101).

The present invention relates to a nanocluster liquid dispersion where nanoclusters with a predetermined number of atoms are dispersed.

A ferrous modified selenium sol for inhibiting accumulation of cadmium and arsenic in rice and the preparation method and application thereof are disclosed. The method includes: dissolving an iron-containing compound and a selenium-containing compound into water; adding a reductant to the solution, and stirring until no more precipitation is generated, then adding carbonate, continuing to stir until no more precipitation is generated, and then filtering, taking the precipitation, and washing to obtain the precipitation of the selenium element and ferrous carbonate; adding an emulsifier to a citric acid buffer solution to obtain an emulsified citric acid buffer solution; adding the precipitation of the selenium element and ferrous carbonate to the emulsified citric acid buffer solution to obtain a sol system; and evaporating to concentrate the sol system, and adjusting the pH to 4.5-8.5 to obtain a ferrous modified selenium sol for inhibiting the accumulation of cadmium and arsenic in rice.
