We fabricated single-walled carbon nanotube (SWCNT) thin-films via the combination of inkjet printing and site-selective deposition based on the patterning of self-assembled monolayers (SAMs) through an optical lithography mask. Previously, we patterned SWCNT films by ultraviolet light irradiation onto SAMs through me…
The photoluminescence (PL) of intrinsic defects and Cr 3+ impurity centers in nanosized alumina (Al 2 O 3 ) crystals of various phase compositions (δ + θ and α phases) has been studied by the method of time-resolved spectroscopy with vacuum-ultraviolet (VUV) excitation at T = 7.5 and 295 K. It is established that the…
In the present work, mechanical behavior of novel sandwich composite panels based on 3D knitted spacer fabrics has been predicted using Finite Element Method (FEM). Composite panels were produced using three different types of spacer fabrics having different structural parameters. The sandwich panels were fabricated b…
A procedure for functionalization of the surface of multiwall carbon nanotubes, based on treatment of the nanofiller with a strong oxidant and 1-hexadecylamine and aimed to improve the compatibility of nanotubes with a polypropylene matrix, was examined. Variation of the mechanical and electrical properties of the com…
This work involves study the effect of tobacco smoking (cigarette, water-pipe smoking) yields on the corrosion of dental alloys (Co-Cr-Mo, Ni-Cr and T i-Al-V alloy) in artificial saliva with pH=4 and temperature of 37oC. This study was performed with electrochemical technique by using potentiostat to predict the poten…
Впервые исследована деградация пленок из поли(3-гидроксибутирата) и поли(3гидроксибутирата-со-3-гидроксивалерата) в солоноватоводном озере Шира на различных глубинах: 3, 9, 13 и 20 м, соответствующих горизонтам стратификации озера.Показано, что наиболее активно деградация пленок (снижение массы пленок и молекулярной м…
Abstract The aim of the aqueous electrokinetic experiments in the present study was to assess the relative contribution of the conducting polyindene (PIn) and inorganic colemanite components to the zeta (ζ) potentials of the composite particles, thus providing further insight into their surface composition in the disp…
As a preliminary step towards the design of carbon-nanotube-based nano-antennas, we investigate the resonant behavior of bundled carbon nanotubes in a monopole configuration. Simulation is performed using a 3D EM method to ensure comprehensive coverage of the various effects in the bundle. The necessary trade-offs bet…
Abstract Hybrid cords of two different polyamide yarns, poly(p-phenylene terephthalamide; aramid) and poly(hexamethylene adipamide; nylon 6.6) have been investigated. Aramid is a high-tenacity, high-modulus, low-elongation, and thermally stable yarn material. Nylon 6.6 is a high-elongation, low-modulus, high-fatigue-r…
We report a 500nm graphene field-effect transistor operating at the Dirac point for frequency doubling with maximum output power of −23dBm and a record bandwidth of 3GHz, 2× higher than the state-of-the-art. The experimental device exceeds its ftand fmaxby about 50%. Contact resistance degrades the performance of the…
In this paper, the oriented M-type barium ferrite (BaM) thick films with different thicknesses are prepared by tape casting. It is found that the crystallographic alignment degree ( f ), the pore and the squareness ratio ( M r / M s ) are not affected by the thickness of the film. XRD and SEM results show that the thi…
We describe solution-processed sintered nanocrystal solar cells. As the absorber layer, thin-films of CdTe nanocrystals were deposited using a layer-by-layer spin coating process. For Schottky barrier solar cells (ITO/CdTe/Ca/Al), an efficiency of 3.0±0.3% with Voc= 0.53±0.03 V, Jsc= 13.2±0.2 mA/cm2, and FF=43.1±4.2%…
Metal foam has many excellent properties, such as light weight, incombustibility, good thermal insulation, sound absorption, energy absorption, and environmental friendliness. It has two types of macrostructure, a closed-cell foam with sealed pores and an open-cell foam with open pores. The open-cell foam has a comple…
Abstract We propose a new electrode design with different aligned direction for the fringe‐field switching (FFS) mode which can reduce the color difference and gamma shift by using the conventional multi‐domain operation. The LC direction suit a set of perpendicular electrode in the pixel with homogeneous alignment. B…
The effects of glycerol content in modified polyvinyl alcohol-tapioca starch were investigated. A series of plasticized polyvinyl alcohol (PPVA) and TS blends were prepared. Prior to compounding process, PVA was plasticized with 15-40 phr glycerol as well as addition of calcium stearate (CaS) and phosphoric acid. Blen…
The preparation of interconnected mesoporous carbon monoliths (MCMs) derived from phenolic resin/ethylene glycol mixtures based on polymerization-induced phase separation have been investigated for fabrication of complex-shape SiC ceramics. The effect of the ethylene glycol content, curing catalyst and the curing temp…
The IR reflectance spectra of the cubic noncentrosymmetric ferrimagnet Cu2OSeO3 (TC ≈ 60 K) were investigated in the temperature range 10–80 K. Detailed analysis of the symmetry and composition of vibrational modes was conducted on the basis of Raman scattering data and data obtained in this investigation. 68 out of 6…
Hydrophilic cotton fabrics were exposed by low-pressure DC glow discharge plasma in argon atmosphere. The influence of different operating parameters such as treatment time, discharge potential, and operating pressure on the chemical and physical properties of the cotton fabrics is studied. Surface analysis and charac…
Wear resistance surface coatings of different compositions of Alumina–Titania composites (Alumina–3%Titania, Alumina–13%Titania, and Alumina–40% Titania) coatings were made on the components of power looms (gun rod, cylindrical rod, nose cylinder, nose, paddle wheel, and paddle wheel pin) and solid lubricant surface c…
This paper describes a model-based control design for a solid oxide fuel cell and gas turbine (SOFC/GT) combined cycle system. One-step ahead predictive control is formulated to (1) meet the power demand effectively, (2) handle the multiple constraints of the hybrid system, and (3) minimize the fuel consumption. An SO…
