Rod-shaped copper (Cu, Cu2O) nano catalyst for the facile oxidation of methanol

Kalawati Saini; Pravin P. Ingole; Smriti Sharma Bhatia; Nutan Rani

Volume 9, Issue 1 , January 2018, , Pages 36-41


  Copper and copper oxide (Cu2O) nanoparticles (NPs) were synthesized by electrochemical route using 2.55 mM tri-sodium citrate (TSC) as a capping and reducing agent. Synthesis was conducted at 15 V and 373 K in the presence of pH 4.22 using a copper rod as a working electrode and a platinum wire as a ...  Read More

Yasaman Kolvandi; Mohammad Aghagholizadeh; Saeed Sheibani

Volume 8, Issue 1 , January 2017, , Pages 82-87


  In this paper, the possibility of production of Cu matrix nano-composite powder containing 10, 37 and 54 wt.% NiO using mechano-chemical reduction of different copper oxides (CuO and Cu2O) was studied. Structural evolutions were characterized by X-ray diffraction. Also, the microstructure was characterized ...  Read More

Mixed influence of copper and some f-block elements on thermoluminescence intensity of CaSO4: Dy, P phosphors  

J. A. Wani; N. S. Dhoble; S. J. Dhoble

Volume 5, Issue 1 , January 2014, , Pages 52-58


  Very little data on copper co-doped CaSO4: Dy and CaSO4: Dy, P phosphors seems to have been reported so far. In the present study the influence of copper and rare earths co-doping on thermoluminescence intensity of CaSO4: Dy, P phosphor has been investigated. Acid evaporation re-crystallization method ...  Read More
