Topological constraint theory (TCT) has enabled the prediction of various properties oxide glasses as a function their composition and structure. However, robust application TCT relies on accurate knowledge network structure topology. Here, based classical molecular dynamics simulations, we derive fully analytical model describing topology calcium aluminosilicate [(CaO)x(Al2O3)y(SiO2)1?x?y, CAS...

For the several decade years, organic light-emitting diodes (OLEDs) have been intensively studied because of their potential applicability to large-size flat panel displays, and more recently also solid-state lighting [1-4]. However, the lifetimes of the organic electronic devices are one of the most matters for the practical use of such devices, because of the ambient moisture and oxygen immed...

BACKGROUND Antibiotic resistant bacteria can be considered as a main problem in infection management. Zinc oxide nanoparticles (ZnO NPs), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. METHODS In this study, Zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

This study investigates the potential of golden shower foliage (GSF) fermentable sugars for sustainable bioethanol production. Utilizing chemical and biological pretreatments involving agents such as sodium hydroxide (NaOH), calcium oxide (CaO), Trichoderma reesei. The research analyzed various aspects including reducing sugar coefficient, total sugar, degree polymerization (DP), derived energy...

Nanosized iron oxide particles exhibit osteogenic and radiopaque properties. Thus, iron oxide (Fe3O4) nanoparticles were incorporated into a biodegradable polymer (poly-L-lactic acid, PLLA) to fabricate a composite bone screw. This multifunctional, 3D printable bone screw was detectable on X-ray examination. In this study, mechanical tests including three-point bending and ultimate tensile stre...

Calcium carbonate and calcium-magnesium carbonate in the form of limestone, dolomite, marl, chalk, and Oyster shell are one of the most widely utilized non-metallic materials in the industrial world. The largest use of limestone or calcium carbonate is in the cement industry where it is used as a source of CaO and also in the concrete industry where it is used as the primary coarse aggregate. F...

BACKGROUND Superparamagnetic iron oxide nanoparticles have been used in clinical applications as a diagnostic contrasting agent. Previous studies showed that iron oxide nanoparticles deposited in the liver and spleen after systemic administration. The present study investigated the effect of iron oxide nanoparticles on antigen-specific immune responses in mice sensitized with the T cell-depende...

The effects of substrate temperature on the structural, optical, medical and electrical characteristics of Cadmium Oxide (CdO) films are investigated in the current study. Films are deposited on glass substrate at different temperatures, ranged between 450–600 oC, using Spray Pyrolysis Technique. According to X– Ray Diffraction (XRD), it is found that the films are polycrystalline and Cadmium O...

gd2o3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. first, gd(oh)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (pc) mode. the deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. the electrodeposited precursor was the...

We present a general study on a high performance supercapacitor based on intercalated reduced graphene oxide with carbon black nanoparticles. Graphene oxide sheets were synthesized by oxidation and exfoliation of natural graphite and were reduced using hydroiodic acid in the presence of carbon black nanoparticles. Graphene paper was fabricated by one-step procedure via simultaneous reducing and...
