Upconversion nanoparticles (UCNs) find application in nanomedicine as biolabels to identify cancer cells. In this work, Y2O3: Er3+/ Yb3+ and Gd2O3: Er3+/ Yb3+ systems were fabricated by combustion synthesis (CS) and sol-...

Silver nanowires were synthesized by a polyol method with a detailed control of synthesis conditions such as injection rate, concentration of copper (II) chloride, and silver nitrate to poly(vinylpyrrolidone) ratio. The ...

A facile method for the preparation of cobalt ferrite nanotubes by use of bacterial cellulose nanoribbons as a template is described. The proposed method relays on a simple coprecipitation operation, which is a technique...

The paper presents the results of the synthesis of 3D nanoparticles of Molybdenum Disulfide / Carbon by hydrothermal synthesis using as formation of micelles the tsetyl-3-methyl-ammonium cations. The elemental compositio...

A new methodology to design discrete-time multiple resonant controllers for single-phase uninterruptible power supply inverters is proposed in this study. This methodology is based on classical linear tools and consists ...
