Volume 3, Issue 4 , 2018, , Pages 213-217

  The mechano-chemical technique was employed to synthesise cobalt and indium single and double doped as well as the undoped ZnO nanopowder samples. The X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS) results confirm that the prepared samples were of hexagonal wurzite form. A new peak ...  Read More

Volume 1, Issue 2 , 2016, , Pages 125-130

  We report herein exfoliation of WS2, which is one of the most promising but less investigated among 2D TMDs in binary mixture of diethyl ether (with boiling point=34.6°C) and water. The bulk WS2 powder was first ball milled in toluene for few minutes and at low rpm. Subsequently the powder was kept ...  Read More
