Cr 2 O 3 was prepared using a simple hydrothermal procedure followed by annealing and then used as the electrode material in supercapacitors. The as-prepared Cr 2 O 3 exhibited good electrochemical performances. The maximum specific capacitances were 203F/g at 10mV/s and 130F/g at 1A/g. The Cr 2 O 3 also showed good cycle-life stability and a low resistance,...
A metal (Ag)/dielectric (AgI) hollow glass waveguide is a novel and flexible fiber for the delivery of high-power IR laser radiation. The surface roughness of the Ag films is one of the key factors that greatly influence the attenuation of the waveguides. In this paper, with the wet chemistry deposition, Ag thin films were successfully fabricated in silica capillaries, whose inner diameter was 0.53...
