Journal ArticleDOI
Nano-Cutting Fluid for Enhancement of Metal Cutting Performance
TL;DR: In this paper, a nano-cutting fluid is made by adding 1% Al2O3 nanoparticles to conventional cutting fluid and the wettability characteristic of this nano cutting fluid on a carbide tool tip is measured using the macroscopic contact angle method.
Journal ArticleDOI

TL;DR: In this article, an optically transparent metamaterial with broadband absorption is presented theoretically and demonstrated experimentally, which comprises of structures made of resistive films of indium-tinoxide and exhibits over 10 dB absorption in the frequency range of 6.06-14.66 GHz.
Journal ArticleDOI
Effect of carbonaceous reinforcements on the mechanical and tribological properties of friction stir processed Al6061 alloy
TL;DR: In this paper, carbonaceous particles (graphite, carbon nanotubes and graphene) are reinforced in order to assess their effect on mechanical and tribological properties of FSP Al6061.
Journal ArticleDOI
Aluminum Substituted Cobalt Ferrite (Co-Al-Fe) Nano Adsorbent for Arsenic Adsorption in Aqueous Systems and Detailed Redox Behavior Study with XPS.
TL;DR: Detailed XPS study of As 3d, Fe 2p, Co 2 p, and O 1s spectra has been reported in explaining the redox behavior and ligand exchange reactions in supporting arsenic adsorption mechanism.
Journal ArticleDOI
Rotational abrasive flow finishing (R-AFF) process and its effects on finished surface topography
TL;DR: In this article, rotational abrasive flow finishing (R-AFF) is used to finish complex internal and external geometries with the help of viscoelastic abrasive medium, while keeping in mind its low finish and material removal rates.
