ABSTRACT Dichlorocarbene modified graphene oxide (GO-CCl 2 ) was prepared via a facile hydrothermal method by using GO as the substrate material. The morphology and chemical compositions of the as-prepared material were characterized by Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, thermogravime…
Abstract In the study of materials on electron probe devices in the field of action of the electron beam, a contaminating hydrocarbon film is formed, which affects the experimental results. In this paper, we have studied the influence of a contamination film on carbon-film-coated dielectrics on the intensity of cathod…
Two-dimensional layered materials (TDLMs), such as tin sulfide (SnS2), have attracted significant attention due to their vast potential applications in the fields of electronics, optoelectronics, energy conversion, and storage. Tin monosulfide (SnS) is an intrinsic p-type semiconductor in the family of TDLMs. Further…
Abstract An eco-friendly method to synthesis silver nanoparticles using aquatic fungus Saprolegnia parasitica was investigated in current study. The formation of the silver nanoparticles (AgNPs) was initially confirmed by the UV-Visible Spectroscopy. As well as using FT-IR, SEM, and EDX. UV Visible analysis showed a s…
Type 2 diabetes mellitus (T2DM) is characterized by insulin resistance (IR). T2DM is correlated with obesity and most T2DM medications have been developed for enhancing insulin sensitivity. Silk protein fibroin (SPF) from spiders has been suggested as an attractive biomaterial for medical purposes. We generated transg…
Abstract The purpose of this study was to determine the characteristics of leather using vegetable tanning ingredients from the bark of Acacia mangium Willd. Tanning agent ingredients are provided in the form of bark powder and extract. The first phase of the preparation of the bark into powder and the second stage is…
Metrology is an essential aspect of nanomanufacturing. Increasingly, nanoscale three-dimensional features are demanded for advanced applications, increasing the demands on metrology. New fabrication techniques such as roll-to-roll (R2R) processes are being developed for manufacturing large-area nanotechnology products…
Mn-Zn cores are widely used in high-frequency, high-power power electronics applications. In order to manage with kilowatt and even higher power ratings, large cores are required. In this issue the magnetic cores themself are affected by inherent physical parameters, and thus their performances are limited and additio…
When designing inductive components for switched-mode power supplies, the influence of magnetic history on hysteresis loss is customarily assumed to be negligible in steady-state. This, however, does not apply for excitations comprising major and minor loops. This paper demonstrates the significant effects of magnetic…
We present a metasurface that is spacetime-modulated to perform spatial multiplexing. This metasurface is made of a 2D array of patches on a grounded substrate that operates as a mirror with two phase reflection states provided by connecting or disconnecting the patches to the ground with integrated diodes controlled…
Abstract Background: Due to their unique properties, zinc oxide nanoparticles (ZnO NPs) gained a broad utilization in nano-based industries and medicine, which may expose human to increased levels of NPs. Zinc oxide (ZnO) is one of the most commonly utilized material in diverse industrial fields such as dyes, additive…
Abstract— The paper deals with the effect of the electrolyte composition on the protective properties of the PEO-coating on the Zr–1Nb zirconium alloy. To assess the functional properties of the coatings and their topography and microstructure, elemental and phase contents are studied and electrochemical and accelerat…
Abstract An original method of obtaining hydrophobic surfaces from blends of immiscible polymers by creating porosity through removing one of the components of the blend is considered. Polymethylpentene and polyisobutylene are used as polymers. The first polymer, which is crystallizable, is the basis for the creation…
The process of film formation including the initial treatment of thin layers of cellulose solutions in N-methylmorpholine N-oxide with isobutanol followed by washing with water is investigated in detail, and the structural and morphological features of the obtained films are examined. The phase state of the N-methylmo…
Abstract Globally, buildings are responsible for about 45% of energy consumption, 40% of atmospheric emission, 30% of water usage and 30% of waste generation, yielding negative environmental impacts which drove intensive research to achieve a sustainable built environment. Architects are primarily responsible and bear…
Introduction: Dendrimers are highly branched, stable polymeric nanoparticles with functional groups capable of binding other molecules and may increase delivery of chemicals into skin. Materials and Methods: We examined the skin penetration of generation 3 (G3) to generation 6 (G6) polyamidoamine (PAMAM) amine-termina…
BACKGROUND: Lung cancer is one of the most common malignant tumors in human beings, and cisplatin is a widely used chemotherapy drug, but its clinical application is limited because of its dose-dependent toxicity and drug resistance. Chitin is known to have various biological activities including anti-tumor, but the i…
The characteristics of thermosolutocapillary flow bifurcations and pattern evolutions of binary fluid in a rotating cylinder with a top disk on the free surface are investigated through three-dimensional numerical simulations. The mixture of silicon-germanium is employed as the working fluid. For the special case of t…
Phosphate cements originated more than a century ago for specific applications to the field of dentistry. These cements have other applications including: biomaterials with bone applications, stabilization of hazardous waste, and structural cements. However, the applications in civil infrastructure are recent and not…
Abstract In the recent years green synthesis of silver nanoparticles is being have become more advantage than over other biological process because they avoid elaborating process of culturing and maintaining the cells. Also, nanoparticles synthesized from plant extracts is favourite because it is less cost, environmen…
