TL;DR: The surface plasmon resonance peak in the UV-Vis absorption spectra shows maximum absorption at 422 nm and the emission peak at 470 nm have also been studied as mentioned in this paper, indicating that the particles are mostly spherical in shape and the sizes are within 18 nm.
Abstract: Silver nanoparticles have been synthesised by chemical reduction of silver nitrate solution by ethanol. The samples have been characterised by X-ray diffraction study. Transmission electron microscopy reveals the nanostructure of the particles produced. This study infers that the particles are mostly spherical in shape and the sizes are within 18 nm. The surface plasmon resonance peak in the UV-Vis absorption spectra shows maximum absorption at 422 nm. Fluorescence spectra of silver nanoparticles, which show an emission peak at 470 nm have also been studied.

TL;DR: In this article, a semi-empirical model is presented to compute the time variation of scour depth in an evolving scour hole at short abutments (abutment length/flow depth 1), namely the vertical wall, 45° wing wall, and semicircular, in uniform and nonuniform sediments under a clear water scour condition.
Abstract: A semiempirical model is presented to compute the time variation of scour depth in an evolving scour hole at short abutments (abutment length/flow depth 1), namely the vertical wall, 45° wing wall, and semicircular, in uniform and nonuniform sediments under a clear water scour condition. The methodology developed for computing the time variation of scour depth is based on the concept of the conservation of the mass of sediment, considering the primary vortex system as the main agent of scouring, and assuming a layer-by-layer scouring process. For an equilibrium scour hole, the characteristic parameters affecting the nondimensional equilibrium scour depth (scour depth/abutment length), identified based on the physical reasoning and dimensional analysis, are excess abutment Froude number, flow depth—abutment length ratio, and abutment length—sediment diameter ratio. Experiments were conducted for time variation and equi- librium scour depths at different sizes of vertical walls, 45° wing walls and semicircular abutments in uniform and nonuniform sediments under limiting clear water scour conditions (approaching flow velocity nearly equal to the critical velocity for bed sediments ). The present model corresponds closely with the data of time variation of scour depth in uniform and nonuniform sediments obtained from the present experiments and reported by different investigators.
