This study aims to design and analyze the of a batch-type reactor optimize production gold nanoparticles on an industrial scale. The method used in this is computational analysis calculations, including stirring mass balance as initial calculations using Microsoft Excel application manually. calculation results show that designed specifications have volume 21.7335 ft3, cylinder height 13.4612 i...

This paper studies the UV-vis absorbance of colloidal gold nanoparticles at 400 nm and validates it as a method to determine Au(0) concentrations in colloidal gold solutions. The method is shown to be valid with restrictions depending on the investigated system. The uncertainty of the determined Au(0) concentration can be up to 30%. This deviation is the result of the combined influence of para...

About 25 years ago, when I became acquainted with the name Gustav Mie, I was unable to find an entry for him in such major encyclopedias as the Britannica or even in several listings of famous scientists [T. I. Williams, A Biographical Sketch of Scientists (Wiley, New York, 1967); J. Turkevich and L. Turkevich, Prominent Scientists of Continental Europe (Elsevier, New York, 1968)]. This puzzled...

Homodispersed 1.8 nm gold nanoparticles were obtained reproducibly in high yields using the classical Turkevich protocol at a high concentration in a continuous flow capillary reactor. The microfluidic reactor made from commercially available items permitted short mixing, heating and quenching times which are the key parameters of this synthesis.
