In this paper, we review the essential physics that lead to the most impressive properties of two-dimensional (2D) nanocrystals, primarily graphene and transition-metal dichalcogenides (TMD). We also highlight some applications uniquely enabled by these 2D materials in the nanoelectronics domain and discuss the relate…
The high purity silk peptide powder can be obtained by the method of atomizing drying after the boiled silk (sericin) is decolorized, enzymatic dissolved, ion exchange purificated and concentrated. It can be used as the additive of high-grade cosmetics. The amino acid components of sericin provide excellent moisture a…
We investigate the DC transport properties of 60V 2 O 5 -5P 2 O 5 -(35− x )B 2 O 3 - x Dy 2 O 3 ( x = 0.4, 0.6, 0.8, 1.0 and 1.2 mol%) glasses as function of temperature which were prepared using the conventional melt-quenching method. These glasses are characterised by thermo gravimetric-differential thermal analysis…
Abstract The resistance of castings to abrasive wear depends on the cast iron abrasive hardness ratio. It has been anticipated that the white cast iron structure will be changed by changing the type of metal matrix and the type of carbides present in this matrix, which will greatly expand the application area of casti…
For over three decades polyurethanes (PUR or PU) have been reported for application in a variety of medical devices. These polymers consist of hard and soft segments, which allow for more subtle control of their structure and properties. By varying the composition of the different segments, properties of PUR can be tu…
Abstract The Goss texture is a characteristic feature of grain-oriented transformer steel sheets. Generator sheets, which are produced as non-oriented steel sheets, should have isotropic features. However, measurement results of generator sheets, confirmed by crystallographic studies, indicate that these sheets are ch…
Using an atomistic-phase field dislocation dynamics model, we isolate and investigate grain size and stress effects on the stacking fault width created by partial dislocation emission from a boundary. We show that the nucleation stress for a Shockley partial is governed by size of the boundary defect and insensitive t…
A solution-based exfoliation method for obtaining large-area two-dimensional flakes of molybdenum disulfide, followed by the fabrication of electrical devices is presented in this manuscript. The exfoliation method is based on the use of an aprotic solvent, namely, acetonitrile under mild sonication steps. In order to…
Objective(s): This paper describes coating of magnetite nanoparticles (MNPs) with amorphous silica shells. Materials and Methods: First, magnetite (Fe3O4) NPs were synthesized by co-precipitation method and then treated with stabilizer molecule of trisodium citrate to enhance their dispersibility. Afterwards, coating…
Design of cancer-targeting nanotherapeutics relies on a pair of two functionally orthogonal molecules, one serving as a cancer cell-specific targeting ligand, and the other as a therapeutic cytotoxic agent. The present study investigates the validity of an alternative simplified strategy where a dual-acting molecule w…
Since decades, proper material selection plays an important and crucial role in an effective manufacturing system for superior production quality, cost optimization and improved productivity. Systematic selection of materials for a given engineering application begins with the study of different material selection pro…
Tin sulphide (SnS) thin films have been recognized as a potential candidate for solar cells. Many fabrication techniques have been used to grow SnS thin films. The band-gap, E g of SnS films as reported in literature, were found to vary from 1.2–2.5 eV depending on the film fabrication technique. The present work repo…
Superfast chemical dynamics on highly epitaxial LaBaCo2O5+δ (LBCO) heterostructures were systematically studied with symmetric half-cell LBCO/Gd0.2Ce0.8O2 (GCO):Y0.08Zr0.92O2 (YSZ)/LBCO heterostructures on (001) LaAlO3. The electrochemical impedance spectroscopy measurements reveal that the LBCO film electrodes have a…
In this work we examine the performance of the organic acid doped polyaniline to impart protection against corrosion when it is used as additive of long oil alkyd based red oxide primer paint. For this purpose, polyaniline doped with tartaric acid, oxalic acid and citric acid were characterized through FTIR and SEM st…
Previously, iron core-gold shell nanoparticles (Fe@Au) have been shown to possess cancer-preferential cytotoxicity in oral and colorectal cancer (CRC) cells. However, CRC cell lines are less sensitive to Fe@Au treatment when compared with oral cancer cell lines. In this research, Fe@Au are found to decrease the cell v…
PREMISE OF THE STUDY: Coniferous bordered pits are some of the most unique and fascinating microstructures of the lignified cell wall. The pit membrane consists of a margo and a torus region, hence facilitating both xylary water transport and also limiting air intrusion by pit aspiration. Additionally, bordered pits h…
The basic building block of many carbon nanostructures like fullerenes, carbon onions or nanotubes is the truly two-dimensional material graphene. Commercial finite element codes, widely used to predict the mechanical properties of these structures, rely on the knowledge of the mechanical properties of the basic mater…
We have investigated the crystal structure of (Bi1/2Na1/2)TiO3–7%BaTiO3 (BNT–7%BT) by high-resolution neutron powder diffraction (NPD) and high-energy synchrotron radiation X-ray diffraction (SR-XRD) analyses. The NPD study revealed that the BNT–7%BT crystals have a single-phase tetragonal structure with P4b m symmetr…
We describe a new method to generate enhanced terahertz (THz) surface wave (SW) via its coupling with reversed Cherenkov radiation (RCR), excited by a sheet beam bunch which travels in a vacuum above an isotropic double negative metamaterial (DNM). The physical mechanism for the enhancement is that the DNM can support…
AgNbO3 exhibits an antiferroelectric phase transition to the orthorhombic P b c m phase at ∼626 K. At room temperature it exhibits ferroelectric behavior with a large spontaneous polarization. However, the ferroelectric structure is still not well understood, with different groups reporting it to have P b c m symmetry…
