In this work, we present a novel structure of Graphene NanoRibbon Field-Effect Transistor (GNR FET) to reduce short channel effects. In this structure, two side metal gates with lower work-function than the main gate are used in a conventional double-gate (DG) GNR FET topology to provide virtual extensions to source/d…
Multiple oil spill disasters over the last few years have highlighted the challenges of effective oil–water separation. The separation of oil–water micro- and nano-emulsions (emulsions with dispersed droplet sizes in the micro- or nano-meter range) can be particularly difficult.1, 2 Shi et al.3 from the Chinese Academ…
Abstract This article begins with a description of the advantages and disadvantages of thermal spraying. It provides a discussion on the importance of substrate processing prior to coating and the role of undercutting in repair. The article reviews the steps for substrate preparation, namely, cleaning, roughening, mas…
We report the use of water extracts of two invertebrates, snail body and earthworm, as biocompatible reducing agents for the green synthesis of gold and silver nanoparticles. The reaction conditions were optimized by varying the extract concentration, gold ion or silver ion concentration, reaction time, and reaction t…
Sisal fibers (SFs) were pretreated by heat treatment (HT). The SFs were mixed with a biodegradable material, polylactide (PLA), and the composites were prepared by hot press molding. The effects of the HT temperature and time on the mechanical properties of the composites were investigated, and the HT mechanism was st…
We report a novel nanodevice using π-conjugated polymers and inorganic semiconductor dual composite P–N junctions single nanowire constructed by PEDOT–PbS–PPY (EPP) nanowire as a two-input OR gate. The nanodevices logic gate may show some key value in nanoelectronic components. A team led by Yuliang Li from Beijing, C…
The study aims at the targeted imaging using CdTe/ZnTe core shell QDs and delivery of paclitaxel (PTX) loaded fibrinogen coated yellow-QDs (PTX-fib-yellow-QDs) towards breast cancer cells via the alpha5Beta1-integrins. We developed fibrinogen coated different sized CdTe/ZnTe core shell quantum dots of 2-10 nm size, wh…
In order to better understand the electrochemical and mechanical characterizations under different cathodic protection potentials of mild steels, the electrochemical reaction feature in the cathodic potential region was studied by electrochemical methods, surface analysis techniques and microhardness tests. Electroche…
Very fast transient overvoltages (VFTO) may result in insulation failures inside or outside gas insulated switchgears (GIS), and most of them are caused by surface flashovers along insulating spacers according to operational experiences. For a good understanding of the discharge process produced by high voltage pulses…
The NCN-pincer Pd-complex-bound norvalines Boc-D/L-[PdCl(dpb)]Nva-OMe (1) were synthesized in multigram quantities. The molecular structure and absolute configuration of 1 were unequivocally determined by single-crystal X-ray structure analysis. The robustness of 1 under acidic/basic conditions provides a wide range o…
We fabricated α -Fe(100)/Nd 2 Fe 14 B(001) bilayer films with different thicknesses values of the α -Fe layer on MgO(100) substrates by using an ultra-high-vacuum (UHV) magnetron sputtering system. The exchange coupling constant at the heterointerfaces of α -Fe(100)/Nd 2 Fe 14 B(001) was evaluated by analyzing the mag…
The effect of plastic flow localization, which is significant for obtaining ultra-fine-grain metals by intense high-rate plastic straining, is studied numerically. Large-scale localization of plastic flow, which is determined by the geometry of the problem, as well as microscopic localization appearing due to instabil…
Thermoset-elastomer polyurethane (PU) nanocomposites were prepared using two types of tungsten disulphide (WS2) nanoparticles: inorganic fullerene-like (IF) and inorganic nanotubes (INT) through an in-situ polymerization process. The quality of dispersion was evaluated using scanning electron microscope (SEM) and the…
This paper presents a new nonlocal thickness-stretching sinusoidal shear deformation beam theory for the static and vibration of nanobeams. The present model incorporates the length scale parameter (nonlocal parameter) which can capture the small scale effect, and it accounts for both shear deformation and thickness s…
The iterative Boltzmann inversion (IBI) method is used to derive interaction potentials for coarse-grained (CG) systems by matching structural properties of a reference atomistic system. However, because it depends on such thermodynamic conditions as density and pressure of the reference system, the derived CG nonbond…
Hyriopsis cumingii (Lea, Unionidae), a freshwater bivalve species widely distributed in China and commercially exploited for freshwater pearl production, was chosen as the reference model to investigate the protein signature in the organic scaffold matching calcium carbonate crystallization mode. This study takes adva…

The inhibition effect of some pharmaceutical compounds, on copper corrosion in 2 M HNO3 at 30°C was investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrical frequency modulation (EFM) techniques as well as weight loss measurements. Tafel polarization studies have sho…
Abstract This article provides information on thermal spray coating features, which combine to determine the properties of a coating. These include the lamellar or layered splat structure, entrapped unmelted or resolidified particles, pores, oxide inclusions, grains, phases, cracks, and bond interfaces. The article de…
Thin films of bovine serum albumin (BSA) nanoparticles are fabricated via layer-by-layer assembly. The surface of BSA nanoparticles have two oppositely acting functional groups on the surface: amine (NH2) and carboxylate (COO(-)). The protonation and deprotonation of these functional groups at different pH vary the ch…
