Microwave processing steps of 0.95[(K0.5Na0.5)0.94Ag0.06NbO3]-0.05[LiSbO3]/(KNAN-LS) lead free ferroelectric ceramics were optimized for better densification and electrical properties. Calcination temperature and time for single perovskite phase formation were optimized and found to be 850 degrees C for 60 min., respe…
A series of the Tband Dy-doped glasses with Li2O–2B2O3 (or Li2B4O7:Tb and Li2B4O7:Dy) composition were synthesised and their spectroscopic properties were investigated. The Li2B4O7:Tb and Li2B4O7:Dy glasses of high chemical purity and optical quality were obtained from corresponding polycrystalline compounds in the ai…
We demonstrate an effective method to prepare wurtzite phase ZnSe nanoparticles from zincblende ZnSe single crystal using femtosecond pulse laser ablation. The fabricated ZnSe nanoparticles are in spherical shape and uncontaminated while synthesized under ambient environment. By controlling the laser fluences, the ave…
The research described in this present study was part of a larger effort focused on developing a dual substrate, dual fermentation process to produce Polyhydroxyalkanoate (PHA). The focus of this study was developing and optimizing a strategy for feeding a mixture of SCFAs (simulated ARF) and maximizing PHA production…
An integrated study of the effect of IFKhAN-92 on steel pickling in sulfuric acid solutions has been carried out.The inhibitor studied significantly reduces the corrosion rate of the metal but does not hinder the scale removal.It has been shown that the electrochemical component of the scale pickling process is descri…
A nanoporous membrane is coated with catechol-tethered poly(N-isopropylacrylamide). The thermosensitive variation of surface wettability determines the hindered diffusivity of dextran (40 kDa) through the nanopores.
The aim of the present work is to synthesize new nanocomposites based on an acrylic polymeric matrix loaded with cellulose nanowhiskers (CNWs). The acrylic copolymer was prepared by free-radical copolymerization of two monomers widely used for coating applications, namely 2-ethylhexylacrylate (EHA) and glycidyl methac…
There is a growing trend towards “greener” alternatives to the synthesis of materials through the use of renewable chemical resources. In this study, we report the utilization of plant-derived oleyl amine surfactants as porogens for the synthesis of mesoporous silicas in place of the usual alkyl amine surfactants. Ole…
Bagasse, an agricultural waste, was investigated for wood plastic nanocomposite production. The incorporation of nanolayered silicate has been considered in recent years for improving the properties of thermoplastic composite. In this study a composite of polypropylene (PP) and bagasse fiber (BF), with different conce…
In this study, Artificial Neural Network (ANN) approach to predict the stress-strain curve of titanium alloy (Ti-10V-4.5Fe-3Al) was obtained by using layer recurrent neural network that uses Levenberg Marquardt algorithm. In artificial neural network training module volume fraction of α and strain were employed as inp…
The high-temperature thermal expansion and electronic transport properties of the B-site substituted LaCoO3 with both variable oxidation state of cobalt between +2 and +3 (La2Co(Ti1−xMgx)O6, 0 ≤ x ≤ 0.5) and variable Co3+-content relative to the other B-cations (La2Co1+z(Ti0.5Mg0.5)1−zO6, 0.2 ≤ z ≤ 0.6) have been inve…
Density functional theory (DFT) calculations have been performed to investigate the interaction of water molecules with bare and defective surfaces. We show that at high coverages water molecules avoid adsorption close to defect sites, whereas at low coverages adsorption on defective surfaces show a similar adsorption…
We present a method for extending the bandwidth of a metamaterial absorber (MMA) with multiresonance structure. The basic unit cell of the MMAs consists of a periodic arrangement of an electric-LC (ELC) resonator and a square loop structure. The absorption bandwidth of an MMA is effectively extended by combining five…
ITO films were deposited on glass by dc magnetron sputtering. The ITO films have high transmission in the visible and near infrared region. After annealed in vacuum at 350 °C, the ITO films are improved the structure and optical property, with higher grain size, and higher transmission in the visible region but lower…
Sir, Mannitol is commonly used in neuroanesthesia as a hypertonic infusion to reduce intracranial pressure and volume. However, its use can lead to serious electrolyte abnormalities. We report a case of a 23-year-old man, who received 1.5 g/kg mannitol over 20 min during excision of cerebellar hemangioblastoma. After…
Abstract Lenticular array products have experienced a growing interest in the last decade due to the very wide range of applications they can cover. Indeed, this kind of lenses can create different effects on a viewing image such as 3D, flips, zoom, etc. In this sense, lenticular based on liquid crystals (LC) technolo…
This study was to investigate the CO2 reforming under isothermal condition. The fuel conversion efficiency and hydrogen-rich gas production were enhanced via the oxidative dry reforming (ODR) from simulated biogas (50%-CH4+50%-CO2). This paper covers two subjects. The first was to investigate the CO2 conversion charac…

The effect of P, ranging from 0.0 to 0.10 mass%, on the core losses of electrical steels containing 2.0 mass% silicon has been investigated. The core losses were separated into hysteresis losses, classical eddy current losses and anomalous losses. The hysteresis losses were found to decrease with increasing P content…
