Abstract--A modified International System of units, SI, based on simply specifying exact numeric values of seven physical constants, is described. This ?set of...
Exact analytical solutions are used to investigate the complex eigenfrequencies of tensioned beams with a viscous damper attached transversely near a support...
Exact analytical solutions are formulated for the complex eigenmodes of tensioned beams with an intermediate viscous damper. The problem is formulated using the...
Cobalt/gold (Co/Au) bimetallic nanoparticles are prepared by synthesizing Au via chemical reduction in the presence of pre-synthesized Co nanoparticles...
Alignment for tomography using a transmission electron microscopy frequently uses colloidal gold particles as fiducial reference marks. Typically, there is an...
