Ultra-small CuO nanoparticles with tailored energy-band diagram synthesized by a hybrid plasma-liquid process

Ultra Wideband Monopole Antenna Excited by a Capacitive Coupling Feed with Double Band Notch Function

This paper presents the results of a new monopole antenna that exhibits 2.75-10.7 GHz performance. The proposed antenna consists of a radiating patch with notches excited by capacitive coupling feed. Also, the antenna’s truncated ground-plane incorporates a central notch. This modification significantly improves the antenna’s impedance bandwidth by 118% over an ultra-wideband frequency range. T...

Preparation of CuO nanoparticles by microwave irradiation

CuO nanoparticles with an average size of ca. 4 nm have been successfully prepared by microwave irradiation, using copper (II) acetate and sodium hydroxide as the starting materials and ethanol as the solvent. The CuO nanoparticles are characterized by using techniques such as X-ray powder diffraction, transmission electron microscopy, selected area electron diffraction, X-ray photoelectron spe...

A hybrid biofuel cell based on electrooxidation of glucose using ultra-small silicon nanoparticles.

The ultra-small silicon nanoparticle was shown to be an electrocatalyst for the electrooxidation of glucose. The oxidation appeared to be a first order reaction which involves the transfer of 1 electron. The oxidation potential showed a low onset of -0.4V vs. Ag/AgCl (-0.62 V vs. RHE). The particle was used as the anode catalyst of a prototype hybrid biofuel cell, which operated on glucose and ...
