摘要:
A stably-dispersed composite of metal nanoparticles and inorganic clay and a method for producing the composite, in which interlayered charges of the clay are replaced with the metal ions, which are then reduced to metal particles by a reducing agent. The metal particles will not aggregate together and can be stably uniformly dispersed with particle sizes smaller than conventional metal nanoparticles, and therefore have better antibiotic effect, catalytic ability and other advantages. Antibacterials in a solvent containing 0.01 wt % or more of the metal nanoparticles and inorganic clay are prepared and confirmed to be effective.
摘要:
A plug fastening device applied to a socket-forming side having a first fixing portion is provided. The plug fastening device includes a fixing member and a binding member. The fixing member has at least one first coupling portion, and a second fixing portion for being fixed to the first fixing portion. The binding member is capable of binding an end of a plug, and has at least one second coupling portion for being coupled to the first coupling portion. As the binding member is applicable to all kinds of plugs with different specifications, the drawback in the prior art that the conventional plug fastening device cannot be universally used is overcome.
