Novel combustion synthesis of carbon foam‑aluminum fluoride nanocomposite materials
(2018)
The facile, rapid and bulk production of composite materials consisting of carbon nanostructures doped with metal-based compounds has been a significant challenge for various research areas where such types of materials ...
Microstructure and nanomechanical properties of pulsed excimer laser deposited DLC:Ag films: Enhanced nanotribological response
(2017)
Diamond-like carbon:silver (DLC:Ag) thin films, with metal contents as high as 16.8 at.%, have been deposited on silicon substrates using pulsed excimer laser deposition
Fabrication, characterization and applications of novel nanoheater structures
(2013)
Nanoheaters are reactive nanostructures that can generate localized heat through controlled ignition. Besides the widely used nanofoil structure with multiple alternative Al-Ni layers, various new nanostructures have been ...
Solid-state synthesis of Mg 2Si via short-duration ball-milling and low-temperature annealing
(2013)
In this work, a short duration ball-milling of elemental Mg and Si followed by a thermal treatment is suggested in order to synthesize magnesium silicide via solid-state reaction. The formation of magnesium silicide was ...
Effect of silicon nitride/oxide on the structure and the thermal conductivity of CoSi nanocomposites
(2017)
In this work, the fabrication of nanocomposites with silicon nitride/oxide into the thermoelectric matrix of cobalt silicide is presented. The different concentrations of nano-Si3N4 were intentionally introduced by mechanical ...
Effect of Bi-doping and Mg-excess on the thermoelectric properties of Mg2Si materials
(2014)
In this work, Bi-doped magnesium silicide compounds were prepared by applying a combination of both, short-time ball milling and heating treatment. The effect of Mg excess was also studied, aiming towards further improvement ...
Few-step synthesis, thermal purification and structural characterization of porous boron nitride nanoplatelets
(2016)
Hexagonal boron nitride (h-BN) nanoplatelets with 99 wt.% purity, 900 to 2000 nm particle width, 30 to 90 nm particle thickness, 213 m2/g specific surface area (SSA), 66% micropore SSA and 0.85 nm average pore size were ...
Thermal and chemical stability of hexagonal boron nitride (h-BN) nanoplatelets
(2015)
High-temperature properties of boron nitride platelets (200-800 nm in width and 30-50 nm in thickness) were systematically evaluated through thermogravimetric analysis (TGA) in combination with differential scanning ...
Few-layer graphene-like flakes derived by plasma treatment: A potential material for hydrogen adsorption and storage
(2016)
A novel, one-step, wet-free, environmental friendly and high-yield method for producing few-layer graphene powders with large surface areas (up to 800 m2/g) and narrow nanopore sizes (0.7-0.8 nm) using plasma-induced ...
Structural features of ball-milled nanostructured K2Bi 8Se13 thermoelectric material
(2011)
In this work, K2Bi8Se13 material was ball-milled in order to develop nanostructures through the modification of structural features. Structural changes during ball-milling were followed by powder X-ray diffraction measurements, ...
