The nanostructure, wear and corrosion performance of arc-evaporated CrBxNy nanocomposite coatings
(2009)
The composition, nanostructure, tribological and corrosion behaviour of reactive arc evaporated CrBxNy coatings have been studied and compared to CrN. The CrBxNy coatings were deposited on a commercial Oerlikon Balzers RCS ...
Nanostructure, mechanical and tribological properties of reactive magnetron sputtered TiCx coatings
(2008)
This study describes the correlation between microstructure, mechanical and tribological properties of TiCx coatings (with x being in the range of 0–1.4), deposited by reactive magnetron sputtering from a Ti target in ...
Deposition and nanotribological characterization of Sub-100-nm thick protective Ti-based coatings for miniature applications
(2011)
Ti-based protective thin films with thicknesses below 100 nm, intended for miniature applications were deposited using physical vapor deposition magnetron sputtering. X-ray diffraction (XRD), scanning electron microscopy, ...
Tribological properties of twin electron-beam evaporated Cr-N and Al-Cr-N coatings under laboratory sliding and drill experiments
(2008)
The tribological behavior of substoichiometric Cr-N and Al-Cr-N coatings prepared by twin electron-beam evaporation at 450°C was studied. Al-Cr-N coatings with Al to Cr ratios in the range of 1-8 (and nitrogen concentrations ...
Arc-produced short-length multi-walled carbon nanotubes as “millstones” for the preparation of graphene-like nanoplatelets
(2019)
Naturally short-length multi-walled Russian-doll-like carbon nanotubes derived by a catalyst-free arc-discharge method were used as nano-sized “cutters” to transform bulk graphitic sheets into thin/few-layered graphene-like ...
Nanostructured Fe-Ni Sulfide: A Multifunctional Material for Energy Generation and Storage
(2019)
Multifunctional materials for energy conversion and storage could act as a key solution for growing energy needs. In this study, we synthesized nanoflower-shaped iron-nickel sulfide (FeNiS) over a nickel foam (NF) substrate ...
Needle grass array of nanostructured nickel cobalt sulfide electrode for clean energy generation
(2018)
Significant efforts have been focused on the search of earth-abundant elements to solve growing energy issues and to provide bifunctional behavior for both hydrogen and oxygen evolution reaction. Mixed transition metals ...
Plasma-Derived Graphene-Based Materials for Water Purification and Energy Storage
(2019)
Several crucial problems, such as rapid population growth and extended demands for food, water and fuels, could lead to a severe lack of clean water and an energy crisis in the coming decade. Therefore, low-cost and ...
Phase Change with Density Variation and Cylindrical Symmetry: Application to Selective Laser Melting
(2019)
In this paper we introduce an analytical approach for predicting the melting radius during powder melting in selective laser melting (SLM) with minimum computation duration. The purpose of this work is to evaluate the ...
Theory-guided metal-decoration of nanoporous carbon for hydrogen storage applications
(2018)
The current paper presents a combined ab initio and experimental study of H2 adsorption on carbon. Adsorption energetics of a H2 molecule on pristine graphene were obtained for various molecule orientations, showing that ...
