The present research work provides information on the dye removal potential of polypyrrole saw dust composite, prepared by reinforcement of natural wood saw dust (obtained from Euphorbia tirucalli L wood) and polypyrrole matrix phase. Dye adsorption on polypyrrole composite was characterized in terms of adsorption iso…
Supercapacitors, or electrochemical capacitors, are a power storage system applied for harvesting energy and delivering pulses during short periods of time. The commercially available technology is based on charging an electrical double-layer (EDL), and using high surface area carbon electrodes in an organic electroly…
Molecular dynamics simulations of polyimide/copper-nanoparticle composites are implemented to calculate the morphological structures, thermodynamic and mechanical properties, and to investigate their relationships with the nanoparticle dimension and simulation temperature. The results demonstrate that polyimide/copper…
We have fabricated ultrafast dark count-free soft X-ray single-photon detectors (X-SNSPDs) from TaN with various conduction path widths, and we compare their properties with corresponding data from a Nb X-SNSPD. The TaN X-SNSPDs offer an improved detector performance regarding device detection efficiency, latching, an…
Multiferroic Bi0.95Dy0.05Fe1-xCoxO3 (x=0, 0.05, 0.1, 0.15) ceramics were prepared by rapid liquid phase sintering method. We studied the effect of (Dy+Co) doping on the structure, electrical and ferromagnetism properties of BiFeO3 ceramics. The structure and morphology of BiFeO3 ceramics were characterized by X-ray di…
The paper describes the structural and optical properties of Magnesium doped Zinc Oxide (Mg 3.5 %, 6 %, 9 %, 12 % by weight) thin films prepared by pulsed laser deposition technique. The samples are characterized by X-ray diffraction technique, Ultra-violet visible absorption spectroscopy, X-ray photoelectron spectr…
Electrochemical hydrogen permeation tests of pure Fe sheets rusted by cyclic corrosion test (CCT) and atmospheric exposure were carried out under controlled temperature and humidity to investigate the influence of atmospheric corrosion on the hydrogen entry behavior. The hydrogen entry into the Fe specimens rusted by…
Polymer matrix composites are gaining more importance compare to monolithical materials as being more reliable and cheaply available. Polymer matrix composites finding application from household to engineering approach. With the advancement of PMC‟s their properties have been increased by one the addition of one more…
According to the characters of stress-strain curves of soft rock and concrete under impact load,and combining the features of damage body and viscous body,a damage viscoelastic dynamic constitutive model was established.The damage viscoelastic dynamic constitutive model,which was based on the Zhu-Wang-Tang model,was d…
The aim of this study was to develop a procedure for preparing film polyelectrolyte complex pectine/chitosan with increased sorption capacity for heavy metal ions which could be used as adsorbent to remove lead (II) ion in waste water.A film of the polyelectrolyte complex between chitosan and pectin were prepared by m…
Article Topo-chemical modification of fibres by grafting of carboxymethyl cellulose in pilot scale was published on January 1, 2013 in the journal Nordic Pulp & Paper Research Journal (volume 28, issue 1).
Biosynthesis of gold nanoparticles was achieved using chloroauric acid by aqueous extract of Senna siamea plant seed. Here, we reported the eco-friendly method for the preparation of gold nanoparticles in the presence of water, using aqueous extract of Senna siamea plant seed at room temperature. The aqueous extract o…
Nanoparticles are dispersed droplets or solid particles with a size of 10-100nm which are made in different shapes. Nanoparticles have received more attention as antiparasitic drugs in recent years since current antiparasitic drugs have some side effects and their efficacy is not proved yet. Nanoparticles are currentl…

Quantum dots are considered as a new class of fluorescent labels which are robust and bright light emitters. Quantum dots are semiconductor nanocrystals ranging typically between 1-10 nanometers and have ability to glow or fluorescence brightly when excited by a light source such as a laser. They are composed of micro…
The synthesis of nanocrystalline silver (nanosilver, NAg) was a major aim of this work. Nanosilver is a nanomaterial of great interest [1-3] due to its special biocidal properties, which are particularly desirable in various fields such as medicine, cosmetology, materials engineering, construction and others [4,5]. We…
Epoxy/Al2O3 nanocomposites with different weight percentage of Al2O3 nanoparticles (1, 2, 3, 4, 5, and 7%wt.) with average particle size smaller than 50 nm were prepared. Three point bending test was used to determine mechanical properties. Flexural strength reaches maximum at 4%wt. of Al2O3 nanoparticles and then beg…
Five diarylethene derivatives with 2-(2-pyridyl)imidazole as the ethene bridges (PI-BTEs) were synthesized and characterized. The structures and performances of the PI-BTEs (L1–L5) could be modified from not only the thiophene unit, but also the substituent on the imidazole nitrogen. Noteworthily, replacing the thioph…
Magnetic domain switching and hysteresis loops in a single crystal α-iron with and without nonmagnetic particles were simulated based on the Landau-Lifshitz-Gilbert equation of magnetization dynamics. Both the nonmagnetic particle and the 360° domain wall are nucleation sites of an antidirection domain during domain s…
In the present paper, the band structure and density of states of Lu6O5F8 were primarily studied with the help of first-principles calculations, and the indirect band gap of Lu6O5F8 is estimated to be 4.13 eV wide. Lu(OH)1.57F1.43/NH4Lu2F7/Lu6O5F8 nano/microcrystals with diverse morphologies, sizes and dimensions have…
