In this work, impact strength of Sisal and banana (hyb…
We employ the first-principles technique based on the modified Becke—Johnson (BJ) exchange potential for the prediction of the electronic band structure, optical properties, and electron density of the cubic MgIn 2 O 4 spinel compound. It is found that the calculated band gap value with the modified BJ approximation i…
A model of a nonspherical gas bubble is developed in which the Rayleigh-Plesset equation is augmented with second order terms that back-couple the volume mode to a single shape mode. These additional terms in the Rayleigh-Plesset equation permit oscillation energy to be transferred back and forth between the shape and…
The versatility of conjugated thiourea compound enhances the development of molecular wire architectures due to the overlapping of π-electrons which can be applied as potential organic solar cell (OSC). Hence, new innovational and breakthrough are needed for OSC molecules to become competitive in the future since they…
Summary Polymer brush synthesis by surface initiated polymerization (SIP) comprises a powerful strategy to tailor interfacial properties. Among others, the passivation of solid substrates against non‐specific protein adsorption or the implementation of stimuli responsive properties can be achieved. In this context con…
The influence of copper on the structure, mechanical and friction properties of 1.5% aluminum-doped steel with 0.3% carbon was studied. It was revealed that there are macro- and nano-sized copper-containing inclusions, that is confirmed by optical microscopy and TEM. According to the results of roentgen-phase analysis…
Sepiolite deposits have been recently discovered in northeastern Iran. However, there is still little information about its physicochemical and mineralogical characteristics. Therefore, the collapse of the sepiolite (with sizes of < 63 μm) structure induced by temperature elevation in an electric furnace at 350, 550,…
Abstract We have performed Density Functional Theory (DFT) calculations to investigate the influence of carbone nanotube (CNT) size on the properties of the electronic structure of various junction models constructed from (6, 0) CNT and graphene nanoribbon (GNR) units via covalent linkage. Chemical shielding tensors a…
Abstract Reflective color LCDs with high image quality, which have very low power consumption when displaying still images and can also display moving pictures, have been developed. Two key technologies are Memory‐in‐Pixel (MIP) fabrication using LTPS technology, and another is optical property optimization by adoptin…
Abstract Quantum dots (QDs) are a luminescent semiconductor nanomaterial technology that delivers exceptional color for liquid crystal display backlighting unit (LCD‐BLU) applications. We report on the scale‐up of the rapid‐injection, batch synthetic method, and compare it to other proposed manufacturing methods. A di…
Research work on audible noise emitted from overhead line conductors is reviewed, and a unique experimental set up employing a semi-anechoic chamber and corona cage is described. Acoustically, this facility isolates undesirable background noise and provides a free-field test space inside the anechoic chamber. Electric…
The self-bias magnetoelectric (ME) sensor is designed, fabricated, and characterized for detecting weak ac magnetic-field. The two different magnetostrictive materials produce the gradient of magnetization, resulting in an internal magnetic field and a strong ME response. At zero-biased dc magnetic field, a low-freque…
Mono layer graphene (MLG) as a new kind of advanced material is in our focus. MLG indicates a twodimensional structure with quantum confinement effect in its thickness. The MLG based nanomaterial has remarkable potential on electrochemical catalysis and bio-sensing applications. Recently inter sheet sensing systems fo…
Abstract Highly weathered soils of the tropics and subtropics commonly have kaolinitedominated clay fractions. Under acidic conditions prevailing in these soils kaolinite dissolution occurs, contributing to the high levels of soluble Al in these soils. This study evaluates the dissolution behaviour of kaolinites from…
Shape memory alloys (SMAs) are metallic materials that have the capability to recover its original shape eliminating residual strains when subjected to adequate thermal process. This behavior is related to phase transformation induced either by stress or by. During the phase transformation process of an SMA component,…
Aging can significantly modify the dielectric, piezoelectric, and ferroelectric performance of ferroelectrics. However, little attention has been paid to the aging effect during ferroelectric-ferroelectric phase transitions that is essentially correlated with real applications. In this letter, the authors report the a…
The effect of hot extrusion and addition of Y element on the corrosion behavior of Mg–Y alloy was investigated by weight loss, immersion tests and potentiodynamic polarization measurements. The results showed that the grains became finer and uniform by increasing Y element, after extrusion. The corrosion resistance of…
This paper reviews the recent developments on building nanoelectronics for our future information processing paradigm using multiferroic composites. With appropriate choice of materials, when a tiny voltage of few tens of millivolts is applied across a multiferroic composite, i.e., a piezoelectric layer stain-coupled…
The physical complexity and the sensitive parameter dependence of electric conduction in polymer insulation materials make the development of high voltage direct current (HVDC) insulation devices a challenging task. Two prerequisites for a successful design process are discussed: 1) modeling and characterization of in…
New approaches to the problems of criticality of field emission with respect to the construction and technological factors are analyzed, and examples of their practical application are considered. These approaches provide practical applications of carbon nanotubes and carbonaceous planar-edge field-emission structures…
