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…
K2NiF4-type Pr2NiO4 doped with Cu, Cu–Ga, or Co (Pr2Ni0.9Cu0.1O4, Pr2Ni0.75Cu0.25O4, Pr1.91Ni0.71Cu0.24Ga0.05O4, or Pr2Ni0.9Co0.1O4) were synthesized by a solid-state reaction for use as cathodes in an intermediate-temperature (500–700°C) solid oxide fuel cell (IT-SOFC). Pr2NiO4, Pr2Ni0.9Cu0.1O4, Pr2Ni0.75Cu0.25O4, Pr…
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…
In our study, graphene oxide is synthesized by Hummers method. And then, carboxylic acid functionalized graphene (graphene-COOH), thiol-functionalized graphene (graphene-SH), and highly dispersive graphene are prepared by chemical modification of respective groups on the graphene surface. Furthermore, we explore a sol…
CeO2 nanobelts, nanorods and nanowires have been synthesized by a formaldehyde-assisted hydrothermal system. It is found that the morphologies of these one-dimensional (1D) CeO2 nanomaterials are dependent on the components of the corresponding precursors, which is achieved to control the reaction degree of Cannizzaro…
We report on the electronic structure of Ge(9)[Si(SiMe(3))(3)](3)(-). Systematic density functional theory analysis of the electronic shell structure of the cluster and its derivatives reveals that the Ge(9)[Si(SiMe(3))(3)](3)(-) and its neutral counterpart have electronic shells that can be explained using the supera…
Single-crystal nanosheets of magnesium hydroxide were electrodeposited from aqueous magnesium nitrate solution. SAED and in-situ dehydration study confirmed that the single-crystal Mg(OH) 2 nanosheets were grown with their {011} planes for the first time. The average transmittance of the porous Mg(OH) 2 films deposite…
X-ray diffraction studies showed that the structure of (Sr1−xPrx)TiO3 solid solutions at 300 K changes from the cubic Pm3m to the tetragonal I4/mcm with increasing x. The analysis of XANES and EXAFS spectra of the solid solutions revealed that Pr ions are predominantly in the 3+ oxidation state, they substitute for Sr…
In this paper a series of polyurethane (PU) membranes modified by zinc oxide nanoparticles was prepared. The samples were synthesized from 1,6-hexamethylene diisocyanate (HDI), a mixture of polyesters consisting of poly(1,4-butylene adipate) diol (PBA, M 2000) and polycaprolactone diol (PCL, M 2000), dimethylolpropion…
The inhibition efficiency (IE) of Polyacrylamide (PAA) in controlling corrosion of carbon steel in ground water in the absence and presence of Zn 2+ has been evaluated by weight loss method. The formulation consisting of 250 ppm PAA and 50 ppm Zn 2+ has 98% IE. It is found that the inhibition efficiency (IE) of PAA in…
Translocation of a lead cation from the N-core of a porphyrin to a hanging carboxylate group is coupled to a transmetalation process with a second lead cation, leading to a dinuclear species. A novel hanging-atop coordination mode is responsible for the dynamic and stereocontrolled binding of lead to the porphyrin cor…
Amphiphilic polymer surfactants are composed of hydrophilic and hydrophobic polymers and are widely used in targeted drug delivery. The purpose of this study was the evaluation of the effect of molecular weight and molar ratio of dextran on physicochemical properties of dextran stearate polymeric micelles. Dextran ste…
