High-speed stirring at elevated temperatures is shown to be effective in the symmetry-breaking process needed for the growth of the hard-to-synthesize silver nanorods from the polyol reduction of silver ions. This process competes with the facile formation of more symmetrical, spherical and cubic, nanoparticles. Once the seed is formed, further growth proceeds predominantly along the long axis,...

Consider two unit balls in a d-dimensional flat torus with edge length r, for d ≥ 2. The balls do not move by themselves but they are pushed by a Brownian motion. The balls never intersect—they reflect if they touch. It is proved that the joint distribution of the processes representing the centers of the balls converges to the distribution of two independent Brownian motions when r →∞, assumin...

By loading the reverberation chamber (RC) Rician fading can be generated. This paper shows K-factor is reduced by platform stirring. The platform stirring is also used to determine an average K-factor in the chamber, valid for an arbitrary fixed position of the antenna inside the chamber.

BACKGROUND This study aims to investigate the influence of different stirring time for synthesis of silver nanoparticles in glutathione (GSH) aqueous solution. The silver nanoparticles (Ag-NPs) were prepared by green synthesis method using GSH as reducing agent and stabilizer, under moderate temperature at different stirring times. Silver nitrate (AgNO3) was taken as the metal precursor while A...
