High silicon grades of ductile cast iron are known to be highly advantageous in regard to technically relevant properties and economic efficiency. In particular, the outstanding mechanical properties lead to an increasing demand since 2011, the year of incorporation to the EN 1563 standard. However, low impact resista…
Papers are one of the most used materials in food packaging industries. Additives need to be added in order to improve and prolong sensory properties of food. This is to maintain the food quality level before reaching to the end users. A preliminary study has been conducted to produce antimicrobial paper by blending t…
The investigation of porous silicon/silver nanostructured composite layers (PS/Ag) via Raman spectroscopy technique has been carried out. Interpretation of PS/Ag Raman spectra has been proposed. Data from films acquired by varying anodization time showed a significant shift of a Raman peak primarily located at the fre…
Natural fibres are biodegradable, low-cost, and low-density materials found in many parts of the world in large quantities. The comparative properties and competitive advantages make it be a preferred material in many engineering applications. The major challenges associated with natural fibres are its low thermal sta…
Background: Funcionalized multi-walled carbon nanotubes (ox-MWCNTs) were used for the preparation of therapeutic nanoparticles for delivery of some bioactive compounds. Consequently, this work deals with the preparation of grafted MWCNTs with n-vinyl caprolactam in the presence of pomegranate peel extract (P. granatum…
Abstract High performance UV/Visible photodetectors are successfully fabricated from ZnO/fibroin protein‐carbon nanotube (ZFP CNT ) composites using a simple hydrothermal method. The as‐fabricated ZnO nanorods (ZnO NRs) and ZFP CNT nanostructures were measured under different light illuminations. The measurements show…
There has been a considerable interest in developing new types of gels based on a network of fibrous aggregate composed of low molecular weight gelators, also known as supramolecular gels (SMGs). Unlike conventional polymer gels with chemical cross-linking, the network formation in SMGs does not involve any covalent b…
The presence of cavities in cross-linked polyethylene insulated cable is considered a weakness, may be potential sites for partial discharge, which eventually led to cable network failure. These cavities may create strong and inhomogeneous electrical field that usually produce partial discharges. In this paper, the ex…
The structural, electronic, magnetic, and vibrational properties of ${\mathrm{LaFeSiH}}_{x}$ for $x$ between 0 and 1 are investigated using density functional theory calculations. We find that the electronic and magnetic properties are strongly controlled by the hydrogen concentration $x$ in ${\mathrm{LaFeSiH}}_{x}$.…
Magnesium and its alloys are attracted towards all engineering applications like automotive, marine, aerospace etc. due to its inherent high strength to weight ratio. But, extensive use of Mg alloys is limited to the current scenario because of low wear and corrosion resistance behavior. However, equal channel angular…
In this work, free vibration characteristics of functionally graded piezoelectric (FGP) nanobeams based on third order parabolic shear deformation beam theory are studied by presenting a Navier type solution as the first attempt. Electro-mechanical properties of FGP nanobeam are supposed to change continuously through…
This work examines the effect of thermal, electrical and mechanical stress on the electrical insulation system of generator bars. For this purpose, test bars are aging simultaneously and subjected to stress until the insulation fails. The acceleration is achieved by increasing the mechanical stress. In order to detect…
In recent years, the local temperature rise of composite insulators has become a serious problem. Research shows some of the insulators with local temperature rise have partial erosion in the core, while their outer sheath worked well. It is of great significance to study the electric field along the surface of the co…
BACKGROUND: Sericin, because of its ability to remove free radicals and its antioxidant properties, has been used to successfully cryopreserve various mammalian cell types. However, the effects of sericin on cryopreservation of mouse sperm has not been reported. OBJECTIVE: The current study intended to determine the p…
Specific features of the magnetic structure of the BiFeO 3 multiferroic have been investigated by Mössbauer spectroscopy in the temperature range of 150–450 K. The temperature dependence of the anharmonicity parameter of the cycloidal spatial spin-modulated structure has been measured, and the magnetic anisotropy cons…
Low resistance Cu interconnects with CVD Ru liner have been demonstrated for 7 nm node. Ru liner thickness reduction has been achieved by replacing PVD TaN with a bilayer PVD Ta and ALD TaN stack, while maintaining adequate Cu fill performance. The newly proposed barrier stack (PVD Ta/AldTaN) with thin Ru liner studie…
Abstract Cotton-like CoS cluster has been successfully synthesized via a simple one-step hydrothermal route assisted by diethylenetriamine (DETA) as a ligand and structure-directing agent. The structure and morphology of the product were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM),…
A new class of high performance switches has been created based on the conducting-to-insulating phase transitions in the semiconductor materials germanium telluride and vanadium dioxide. The exceptional small signal RF performance of these switches points to a future where generic RF radios can be constructed and prog…
In this paper, a novel power generation cum storage system employing reversible solid oxide fuel cell (RSOFC) has been proposed and modelled. The RSOFC is integrated with solar PV/T system. Here only the electrochemical modelling of the fuel cell unit has been presented and analysed thermodynamically. The RSOFC unit o…
The present study emphasizes on the development of composite material by reinforcing Walnut Shells (WNS) in Epoxy matrix. Composite material was developed using stir casting process at different weight percentages of Walnut Shell from 0-20. Result from tensile test reveal an improvement of tensile and compression modu…
