Arul Murugesan; Robert M Gengan

Volume 3, Issue 7 , 2018, , Pages 475-479

  A simple and efficient procedure for the preparation of boron nitride bound N-propyl triethylenetetramine sulfonic acid (BN-BPTETSA) by the reaction of boron nitride bound N-propyl triethylenetetramine (3-TETANP BN) with chlorosulfonic acid in chloroform is described. The boron nitride (BN) ...  Read More

Surface finish and subsurface damage distribution during diamond turning of silicon

Rohit Sharma; Neha Khatri; Vinod Mishra; Harry Garg; Vinod Karar

Volume 2, Issue 7 , 2017, , Pages 433-435

  Subsurface Damage (SSD), which is introduced to optical materials by diamond turning processes, affects the performance in optical, laser and infrared applications. For optical applications, SSD can be the source of component instability (e.g., surface stress) and flaw. The objective of the present study ...  Read More

Microscopic and spectroscopic evaluation of SPS sintered aluminium-graphene (Al-Gr) nanocomposites

Vipin Jain; Anil Kumar; Ajay Dhar

Volume 2, Issue 3 , 2017, , Pages 146-151

  Graphene possesses excellent properties such as, high Young’s modulus (1 TPa), high fracture strength (~125 GPa) and extreme thermal conductivity (~5000 W/m/K), therefore, can serve as an ideal reinforcement material for the metal based High Tech structural nanocomposites. In the present work, ...  Read More

Role of pH in the hydrothermal synthesis of phase pure alpha Bi2O3 nanoparticles and its structural characterization

M. Malligavathy; D. Pathinettam Padiyan

Volume 2, Issue 1 , 2017, , Pages 51-55

  Phase pure bismite nanoparticles were successfully prepared by means of hydrothermal method by varying the precursor solution pH from 10 to 13. The as-prepared nanoparticles were characterized by different techniques such as X-ray diffraction pattern (XRD), Raman spectroscopy, Scanning electron microscopy ...  Read More
