Techniques are developed to determine the resistance per unit length and the electrical resistivity of vertically aligned carbon nanotubes (VA CNTs) using atomic force microscopy (AFM) and scanning tunneling microscopy (STM). These techniques are used to study the resistance of VA CNTs. The resistance of an individual…
Nowadays, flexible and transparent electronics are receiving much attention in industry and research groups. Aiming at a suitable device for this technology, we present a low-cost and low-temperature integration process for ZnO nanoparticle thin-film transistors using a spray coating technique. An inverted coplanar st…
We report the comparative study of the effect of interaction of nano-second and pico-second laser pulse incident on the solid copper target placed in ambient of air and magnetic field. Larger ablation depth ∼67 μm with clean crater profile is observed in the case of ps-laser pulses compared to ∼31 μm of ablation depth…
Abstract A tough double-network (DN) superabsorbent was synthesized by a two-step method using N , N -methylenebisacrylamide as a covalent cross-linker for one monomer [acrylic acid (AA)], Ca 2+ (CaCl 2 ) as an ionic cross-linker for the other monomer (sodium alginate [SA]) and ammonium peroxodisulfate as the redox in…
Al/Poly (methyl methacrylate) (PMMA)/p-Si organic Schottky devices were fabricated on a p-Si semiconductor wafer by spin coating of PMMA solution. Dielectric properties of the Al/ Poly (methyl methacrylate) (PMMA)/p-Si structure have been studied using temperature-dependent admittance-voltage (C/G-V) measurements at t…
Abstract A new μ‐oxo diiron(III) complex of the lithium salt of the pyridine‐based unsymmetrical ligand 3‐[(3‐{[bis(pyridin‐2‐ylmethyl)amino]methyl}‐2‐hydroxy‐5‐methylbenzyl)(pyridin‐2‐ylmethyl)amino]propanoate (LiDPCPMPP), [Fe2(μ‐O)(LiDPCPMPP)2](ClO4)2, has been synthesized and characterized. The ability of the compl…
AlGaN/GaN high electron-mobility transistors (HEMTs) with 5 nm AlN passivation by plasma enhanced atomic layer deposition (PEALD) were fabricated, covered by 50 nm SiN x which was grown by plasma enhanced chemical vapor deposition (PECVD). With PEALD AlN passivation, current collapse was suppressed more effectively an…
The counter diffusion method is a promising approach for the preparation of zeolitic imidazolate framework-8 (ZIF-8) membranes for propylene/propane separation. The effects of the reaction temperature on the structure and permeation properties of ZIF-8 membranes were evaluated to explore the mechanism of membrane form…
Abstract TiO2/CH3NH3PbI3-based photovoltaic devices were fabricated by a spin-coating method using a mixture solution of niobium(V) ethoxide, and the effects of niobium (Nb) addition to TiO2 layers were investigated. The lattice distance and energy gap of the TiO2 were almost same after Nb addition. The elemental mapp…
Propane steam reforming using a sliding discharge reactor was investigated under atmospheric pressure and low temperature (420 K). Non-thermal plasma steam reforming proceeded efficiently and hydrogen was formed as a main product (H2 concentration up to 50%). By-products (C2-hydrocarbons, methane, carbon dioxide) were…
An electron beam (EB) lithography method using inedible cellulose-based resist material derived from woody biomass has been successfully developed. This method allows the use of pure water in the development process instead of the conventionally used tetramethylammonium hydroxide and anisole. The inedible cellulose-ba…
The exploitation of nanoconfined conversion of Au- and Pt-containing binary nanocrystals for developing a controllable synthesis of surfactant-free AuPt nanocrystals with enhanced formic acid oxidation (FAO) activity is reported, which can be stably and evenly immobilized on various support materials to diversify and…
High resolution plasma transport simulations with the EMC3-EIRENE code have been performed to address the parallel plasma flow structure in the boundary of a poloidal divertor configuration with non-axisymmetric perturbations at DIII-D. Simulation results show that a checkerboard pattern of flows with alternating dire…
We implement the effects of disorder on a holographic p-wave superconductor by introducing a random chemical potential which defines the local energy of the charge carriers. Since there are various possibilities for the orientation of the vector order parameter, we explore the behavior of the condensate in the paralle…
The multi-wavelength tunable plasmonically induced transparency (PIT) phenomena in two-ring and three-ring systems at infrared range were theoretically and numerically investigated. In the two-ring system, changing the bias voltage of graphene ring or the separation between graphene rings would induce an off-to-on PIT…
This study aimed to examine the effectiveness of combined microwave-ultrasonic pasteurization system on Escherichia coli and vitamin C content in sour cherry juice (SCJ). Based on the findings, microwave output power, ultrasound power, and ultrasonic exposure time as well as the microwave-induced temperature were the…
We propose a scheme for the distillation of partially entangled two-photon Bell and three-photon W states using metamaterials. The distillation of partially entangled Bell states is achieved by using two metamaterials with polarization dependence, one of which is rotated by π/2 around the direction of propagation of t…
The thermal reactions of the heteronuclear oxide cluster [Ga2 MgO4 ](.+) with methane and water have been studied using state-of-the-art gas-phase experiments in conjunction with quantum-chemical calculations. The significant reactivity differences, favoring activation of the strong OH bond, can be ascribed to a prot…
The osseointegration capacity of bone-anchoring implants can be improved by the use of drugs that are administrated by an inbuilt drug delivery system. However, to attain superior control of drug delivery and to have the ability to administer drugs of varying size, including proteins, further material development of d…
Solvent-free N-allylation of chitosan with allyl bromide was performed under shear deformation in an extruder and the obtained chitosan derivatives were successfully used for the microfabrication of 3D structures by laser stereolithography.
