Abstract: A silver ink including silver particles and a protective agent containing at least one amine compound dispersed in a dispersion medium containing, as a main solvent, a solvent having a vapor pressure at 20° C. of 40 mmHg or less and a vapor pressure at 70° C. of 0.09 mmHg or more, in an amount of 80% or more on a mass basis relative to the total dispersion medium. The amine compound has a mass average molecular weight of 115 or less, and the total amount of the amine compound is 1 part by weight or more and 14 parts by weight or less per 100 parts by weight of the silver particles. The silver ink has a moisture content of 500 ppm or more and 50,000 ppm or less and enables a practical metal film to be formed even through calcination at a low temperature of 70° C. or less.

Abstract: The present invention provides an undercooling solidification method for preparing an amorphous or nanocrystalline soft magnetic alloy with high Fe content and the applicable amorphous or nanocrystalline alloy composition. The undercooling solidification is realized by glass purification combined with cyclical superheating or electromagnetic levitation melting. An undercooling solidification alloy is prepared into amorphous strips or powders through rapid quenching or atomization of melt, and can be prepared into a nanocrystalline alloy through heat treatment. The chemical formula of the applicable amorphous or nanocrystalline alloy is FeSiBM, wherein M is one or more of P, C, Nb, Mo, Zr, Hf, Mo, Y, Cu and Co. The amorphous or nanocrystalline alloy prepared by undercooling non-equilibrium solidification has the characteristics of high amorphous forming ability, high saturation magnetization and low coercive force.

Abstract: The present invention relates to novel gold nanocrystals and nanocrystal shape distributions that have surfaces that are substantially free from organic impurities or films. Specifically, the surfaces are “clean” relative to the surfaces of gold nanoparticles made using chemical reduction processes that require organic reductants and/or surfactants to grow gold nanoparticles from gold ions in solution.
The invention includes novel electrochemical manufacturing apparatuses and techniques for making the gold-based nanocrystals. The invention further includes pharmaceutical compositions thereof and the use of the gold nanocrystals or suspensions or colloids thereof for the treatment or prevention of diseases or conditions for which gold therapy is already known and more generally for conditions resulting from pathological cellular activation, such as inflammatory (including chronic inflammatory) conditions, autoimmune conditions, hypersensitivity reactions and/or cancerous diseases or conditions. In one embodiment, the condition is mediated by MIF (macrophage migration inhibiting factor).

Abstract: A powder recycling system includes a supply tank, a continuous loss-in-weight module, a pneumatic module, a transfer channel, a recycle module, and a refilling tank. The supply tank accommodates recycling powder. The continuous loss-in-weight module includes a storage tank receiving the recycling powder from the supply tank and a rotary output pipe connected to the storage tank to output the recycling powder. The continuous loss-in-weight module controls the mass flow rate of the output of the recycling powder according to the weight change of the storage tank. The pneumatic module enables the recycling powder to float and move in the transfer channel. The recycle module is connected to the transfer channel to receive the recycling powder, sieves the recycling powder, provides virgin powder, and mixes the virgin powder with the recycling powder. The refilling tank is connected to the recycle module to receive the recycling powder and the virgin powder.
