Abstract: A holder of a portable electric device includes a main body formed integrally. The main body has an intermediate portion formed with a recessed wire-collecting portion, having one end provided with a holding portion having an outer wall disposed with a crevice and a wire-positioning hole bored under the crevice, and another end formed with a clamping portion having an outer wall cut with a clamping opening, a crevice, and a wire-positioning hole bored inside the crevice. Thus, the clamping opening can clamp the portable electric device and the holding portion can be fixed on a table top to have the portable electric device positioned obliquely at an appropriate angle for facilitating browsing and operating. Further, the wires of the portable electric device or of its peripheral products can be positioned in the wire-collecting holes and orderly wound on the wire-collecting portion.

Abstract: A wireless light indication and control device connected with a helmet is provided. The wireless light indication and control device includes a direction detector, a wireless transmitter, and at least one light element, wherein the direction detector senses a movement of the helmet to generate a turning signal, the wireless transmitter receives the turning signal and cooperates with a frequency hopping unit and a matching unit to generate a wireless signal, and the light element includes a wireless receiver for receiving the wireless signal.

Abstract: A process for preparing metal nanoparticles, comprising reacting suitable metal salts and anionic surfactant containing an anionic group of carboxylic group (COO−), sulfate group (SO42−) or sulfonate group (SO32−) as reducing agent in water under reflux at a temperature of 50-140° C., such that under the reducing power of said anionic surfactant itself, the metal salts can be effectively reduced into metal nanoparticles having a uniform particle size and that the reaction will be not too fast, no large microparticle will be formed, the yield will not be lowered, and the nanoparticle thus prepared can be dispersed stably in polar and non-polar solvent.

Abstract: A method of activating a non-conductive substrate for use in electroless deposition is proposed, in which an aqueous solution containing nanoparticles of noble metals and their alloys is used as an activation solution in an electroless plating process, so as to electrolessly deposit a conductive metal deposition on the substrate and into micrometer-sized trenches formed on the substrate. By using this method with provision of a solution of a copper or nickel salt, copper or nickel can be deposited on the non-conductive substrate, allowing high aspect-ratio trenches on the substrate to be filled with copper or nickel for subsequent use in fabrication of integrated circuit interconnection.
