Numerical Evaluation of the Mechanical Behavior of a Particulate Composite Material as Reinforcement in Timber Beams
Beams are structural elements commonly used in structure for construction designs. The use of wood as structural elements is very important because it is a material of renewable source, low density and satisfactory mechanical performance. When the wood surface is not properly treated, the structure can be destroyed no…
Effect of Hydrothermal Treatment on Structural Character of Palygorskite and Adsorption Efficiency for Methylene Blue
Palygorskite is widely used as an adsorbent for all kinds of pollutants in wastewater. The effect of hydrothermal treatment parameters including temperature and time on palygorskite's structural character and its adsorption of methylene blue were studied. The structures of the prepared palygorskite adsorbent were char…
Characterization of High Density Solid Waste Biopolymer Foam
Waste cooking oils are problematic disposal especially in the developed countries. Management of such oil is a significant challenge due to the disposal problems and possible contamination of the water and landfills. Thus, paper presented the synthesized of polyol based on waste cooking oil as raw material to produce…
Graphene Self Switching Diodes with high rectification ratios
This paper presents a new Graphene nanodevice that acts as a two terminal nanorectifier with a high rectification ratio, without the need for a p-n junction or a third gate terminal. The device's operation is similar to that of Self-Switching Diodes (SSD) and is therefore named here as a Graphene Self-Switching Diode…
Periodic solutions for nonlinear oscillations of nanowires using variational iteration method
Nonlinear oscillation of nanowires, based on the Timoshenko beam theory, are investigated. The analytical solution of the nanowire structure using the Galerkin technique together with the variational iteration method is developed. A coupled nonlinear differential equation is obtained utilizing the Galerkin technique.…
Electronic structure and quantum criticality in Ba(Fe 1-x-y Co x Mn y ) 2 As 2 , an ARPES study
We used angle-resolved photoemission spectroscopy (ARPES) and density functional theory calculations to study the electronic structure of Ba(Fe1-x-yCoxMny)2As2 for x=0.06 and 0<=y <=0.07. From ARPES we derive that the substitution of Fe by Mn does not lead to hole doping, indicating a localization of the induced holes…

Antibacterial Gold Nanoparticles-Biomass Assisted Synthesis and Characterization
Xylose is a natural monosaccharide found in biomass such as straw, pecan shells, cottonseed hulls, and corncobs. Using this monosaccharide, we report the facile, green synthesis and characterization of stable xylose encapsulated gold nanoparticles (Xyl-GNPs) with potent antibacterial activity. Xyl-GNPs were synthesize…
THE CRYSTAL CHEMISTRY OF THE GRAFTONITE-BEUSITE MINERALS
The crystal structures of seven members of the graftonite-beusite series, ideally (Fe 2+ ,Mn 2+ ,Ca) 3 (PO 4 ) 2 , monoclinic P 2 1 / c, a 8.77–8.81, b 11.43–11.58, c 6.13–6.17 A, β 99.19–99.32°, V 607.5–617.7 A 3 , have been refined to R 1 indices of 2.1–3.7% using ~1300–1600 unique observed reflections (| F o | > 5…
Dual-targeting Janus Dendrimer Based Peptides for Bone Cancer: Synthesis and Preliminary Biological Evaluation
The development of dual-targeting drug delivery system is helpful to overcome the poor physiochemical properties of chemotherapeutic agents. The RGD sequence has a potential dual-targeting property, with which the chemotherapeutic agents can be delivered to bone tissue and tumor. And the Janus dendrimer which consists…

Improvements on lifespan modeling of the insulation of low voltage machines with response surface and analysis of variance
The aim of this paper is to present some improvements of the method for modeling the lifespan of insulation materials in a partial discharge regime. The first step is based on the design of experiments which is well-known for reducing the number experiments and increasing the accuracy of the model. Accelerated aging t…
Measuring Stress Condition in Hard Faced Work Rolls for Cold Rolling
The paper proves that it is possible to use grooving to measure volume and type of residual stresses distribution in hard faced hard faced work rolls for cold rolling with high hardness of an active layer.
Investigation of physicochemical and tribological properties of transparent oxide semiconducting thin films based on Ti-V oxides
In this paper investigations of structural and optical properties of nanocrystalline Ti-V oxide thin films are described. The films were deposited onto Corning 7059 glass using a modified reactive magnetron sputtering method. Structural investigations of prepared Ti-V oxides with vanadium addition of 19 at. % revealed…
Self-assembly and switching in ferroelectrics and multiferroics
Molecules of low symmetry often self-assemble in Nature to produce mesoscopic structures of symmetry higher than their constituent building blocks, including "super-cubic" structures. Such self-assembled hexagonal domains have recently been observed in orthorhombic polymeric ferroelectrics, and resemble those known in…

On Molecular Gelation Mechanism of L-Cysteine Based Hydrogel
A method for preparing a supramolecular hydrogel composed of a mixture of L-cysteine, and silver nitrate is reported. The main features of the hydrogel are gelation at low content of the dispersed phase (~ 0.01%) induced by addition of various salts (sulfates, sulfites, chlorides, bromides, and others) and thixotropic…
Preparation of Skeletal Cu Catalysts by Thermal and Chemical Treatment of Cu–Ti Amorphous Alloys and Their Enhanced Catalytic Activities
Abstract Skeletal Cu was prepared from Cu–Ti amorphous alloy (amor-CuTi) via heating at various temperatures followed by HF treatment for extraction of Ti moieties. Thermal treatment at somewhat lower crystallization temperature of amor-CuTi followed by HF treatment leads to higher catalytic activity in the hydrogenat…
Ordering state in orthopyroxene as determined by precession electron diffraction
Fe 2+ and Mg distribution on octahedral M1 and M2 sites of the orthopyroxene structure is an indicator of the cooling rate and closure temperature of the mineral. It is generally obtained by single-crystal X‑ray diffraction, which is limited in spatial resolution. In this work, we determine the cationic distribution a…
