Corrosion behavior and characterization of plasma nitrided and borided AISI M2 steel [PDF]
Materials Research, 2014 This study investigates the corrosion behaviors of plasma nitrided (PN) and borided AISI M2 steels. The PN process was carried out in a dc-plasma system at a temperature of 923K for 6 h in a gas mixture of 80%N2-20%H2 under a constant pressure of 5 mbar.

Aggregation-Induced Fluorescence of Carbazole and o-Carborane Based Organic Fluorophore
Frontiers in Chemistry, 2019 Carbazole based fluorophores 9-butyl-3,6-bis-(phenylethynyl)-9H-carbazole (1) and 9-butyl-3,6-bis-(2-phenyl-o-carborane)-9H-carbazole (2) were synthesized via Sonogashira type cross-coupling reaction and followed by insertion with decaborane.

First Principles Simulations of Boron Diffusion in Graphite [PDF]
, 2007 Boron strongly modifies electronic and diffusion properties of graphite. We report the first ab initio study of boron interaction with the point defects in graphite, which includes structures, thermodynamics, and diffusion. A number of possible diffusion

Mechanical properties of atomically thin boron nitride and the role of interlayer interactions [PDF]
Nature Communications, 2017 Atomically thin boron nitride (BN) nanosheets are important two-dimensional nanomaterials with many unique properties distinct from those of graphene, but investigation into their mechanical properties remains incomplete. Here we report that high-quality

Defect-induced B4C electrodes for high energy density supercapacitor devices
Scientific Reports, 2021 Boron carbide powders were synthesized by mechanically activated annealing process using anhydrous boron oxide (B2O3) and varying carbon (C) sources such as graphite and activated carbon: The precursors were mechanically activated for different times in ...
