Alternating surface oxide and hardened layers were fabricated by means of anodic plasma nitrocarburizing of low-carbon steel in aqueous ammonium chloride/carbamide solutions. The effect of electrolyte composition and treatment conditions on the phase characteristics, structure and properties of the surface layers was…
Nano∕micro-scale mechanical properties of multiferroic materials can be controlled by the external magnetic or electric field due to the coupling interaction. For the first time, a modularized multi-field nanoindentation apparatus for carrying out testing on materials in external magnetostatic∕electrostatic field is c…
A method for measuring the surface conductivity in porous electrodes was developed. The knowledge of surface conductivity is very important for simulation and optimization of the capacitive deionization of aqueous solutions, which is a new promising and economical method for water desalination. The surface conductivit…
Two complementary X-ray diffraction schemes with orthogonal diffraction vectors are proposed to study the structural state of ion-plasma coatings of the quasi-binary Ti-W-B system: one with a diffraction vector oriented parallel to the normal to the coating surface and the other with a diffraction vector oriented perp…
Review of results in anodic plasma electrolytic saturation of structural steels with nitrogen and carbon in the aqueous electrolytes containing ammonia chloride and required additional constituents is presented. Proposed nitrohardening technology of the medium-carbon steels includes the short-time nitrogen saturation…
This paper presents a comprehensive set of Simulink models, utilizing SimPowerSystems blockset to simulate various power quality events in distribution system. These models include distribution line fault, induction motor starting and transformer energizing models which are used to simulate various types of voltage sa…
The effects of adding Nano-Silica particles on the compressive strength and water permeability of concrete and its comparison with that of Micro-Silica were investigated in this work. The effect of combination of Nano- silica and Micro-silica were also studied in this work, which resulted in an increase in compressive…
Ovarian cancer is the fifth-leading cause of cancer-related deaths among women as a result of late diagnosis. For survival rates to improve, more sensitive and specific methods for earlier detection of ovarian cancer are needed. This study presents the development of rapid and specific one-step circulating tumor cell…
Linamarin-loaded poly (lactide-co-glycolide) (PLGA) nanoparticles (NPs) were prepared by the double emulsion solvent evaporation technique. The formulated PLGA (50:50) and PLGA (85:15) NPs were spherically shaped, having an average particle size < 190 nm, drug entrapment efficiency (50-52%) and zeta potentials ranging…
Flux switching machines (FSMs) that consist of all flux sources in the stator have been developed in recent years due to their advantages of single piece and robust rotor structure suitable for various speed applications. They can be categorized into three groups that are permanent magnet (PM) FSM, field excitation (F…
Sir, Peptic ulcer is an inflammation in the lining of the stomach or duodenum with Helicobacter pylori being the major cause.[1] The standard therapeutic measure is to eradicate the bacterial infection among them. One week “triple therapy” is recommended as the treatment of choice, consisting of a proton pump inhibito…
Cardiovascular disease is a major cause of morbidity and mortality throughout the world. Most cardiovascular diseases, such as ischemic heart disease and cardiomyopathy, are associated with loss of functional cardiomyocytes. Unfortunately, the heart has a limited regenerative capacity and is not able to replace these…
Si wafers of (100), (110) and (111) orientations were bombarded by gas cluster ion beam (GCIB) of 3000 Ar-atoms/cluster on average at a series of angles. Similar surface morphology ripples developed in different nanoscales. A simple scaling functional satisfactorily describe the roughness and wavelength of the ripple…
Abstract We have fabricated a back‐channel‐etched TFT using the CAAC‐IGZO film that we developed. As a factor of success in manufacturing stable back‐channel‐etched TFTs, it is considered that CAAC‐IGZO has a strong structure because of its crystallinity. For verification, we have compared the cohesive energy of c‐IGZ…
TiO2-TiN composite catalysts were prepared by oxidizing the TiN films in air at 350 °C. By adjusting the oxidation time to control the oxidation stage of TiN films, the optical band gap of the TiO2-TiN composites can be varied in a wide range from 1.68 eV to 3.23 eV. These composite films all showed red shift in photo…
Despite being a subject of intense research and exclusive attention over the past several decades, hydrogen in the weldments of high strength steels continues to seriously limit the performance of the components and confounds the quantitative component prognosis. More than 1500 studies in the literature have reported…
Polyhydroxyalkanoates (PHAs) are biological polyesters produced through microbial fermentation processes. They have attracted attention as an alternative source to petro-chemically derived plastics as they are biodegradable, renewable, biocompatible and environmentally friendly. However, a notable limitation for their…
We propose an ultrathin wide-band metamaterial absorber (MA) based on a Minkowski (MIK) fractal frequency selective surface and resistive film. This absorber consists of a periodic arrangement of dielectric substrates sandwiched with an MIK fractal loop structure electric resonator and a resistive film. The finite ele…
Multiple approaches have been devised and evaluated to computationally estimate binding free energies. Results using a recently developed Quantum Mechanics (QM)/Molecular Mechanics (MM) based Free Energy Perturbation (FEP) method suggest that this method has the potential to provide the most accurate estimation of bin…
Micro–nano patterns created directly over solid surfaces to combat microbial activity help in preventing hospital‐acquired infections. This Letter is focused on defining surface topologies by laser patterning over solid surfaces. Studies on designing surface topologies and bacterial culture have been carried out and t…
