Despite increased nanoresearch, the influence of nanoparticles on the immune system is still poorly understood. Recently we demonstrated ex vivo modulation of T lymphocytes from aged mice post exposure to a mixture of nanodiamond (ND) and nanoplatinum (NP) coated material (DPV576-C). Here, we extend our study to exami…
The temperature of the feedstock in continuous extrusion process plays a vital role in the deformation of feedstock. Temperature of the feedstock has considerable effects on the process characteristics of continuous extrusion process such as total load and torque required to extrude the feedstock through the die orifi…
Ultraviolet (UV) cured liquid and powder coatings provide plastic part manufacturers with a number of desirable benefits including enhanced appearance, improved performance and various process advantages. At the same time, the rapid film formation and densely cross-linked chemistry that characterize UV curable materia…
Intensive research concerning semicrystalline polymers have been conducted for many years. Unabated interest in this class of materials results mainly from their unique properties but also from exceptionally complicated structure. Full description of plastic deformation of such materials requires considering the prese…
Pure and rare earth metals (La 3+ and Nd 3+ )doped Metanitroaniline (mNA) single crystals are g rown by slow evaporation technique. Both the pure and th e doped crystals crystallize in the orthorhombic st ructure. The reduction in the intensity observed in powder X -ray diffraction of doped specimen and slight shift s…
In this work the researches are conducted on studying of superficial characteristics of cotton fiber, changes of cotton fiber after influence of various technological solutions. It is shown that sorption ability of fiber can be increased with change of a form of the internal channel of fiber.
Abstract — The geotechnical properties of the Barton Clay from the Hampshire Basin in England are presented. Barton Beds are important lithologies for many prominent micro and macro fossils in Britain. The common index properties of the clay soil for engineering including moisture content, plasticity, liquid limit and…
The scope of the present work was to study the release of methylene blue from a composite material based on collagen and hydroxyapatite. The obtaining of the composite material was achieved by co-precipitation of hydroxyapatite in the collagen matrix (at a pH of 10.5). Later, methylene blue was added dropwise because…
Hydroxyapatite (Hap) was synthesized from cuttle fish bone by using a wet chemical method at room temperature. In this method powdered cuttle fish bones were reacted with phosphoric acid (H3PO4). The synthesized Hap was characterized by Atomic Force Microscopy (AFM), Fourier Transform Infrared Spectroscopy (FTIR) and…
A novel entry toward poly( 2,6-diimidazo(4,5-b: 4’,5’-e)pyridinylene-1,4(2,5-dihydroxy)-phenylene) (PIPD) has been elaborated. A strategy based on a new route to monomers: a sequential nitration of 2,6-diaminopyridine with KNO3/H2SO4 gives 2,6- diamino- 3,5-dinitro pyridine (DNDAP) in moderate yield and its hydrogenat…
PEM fuel cell assembly pressure is known to cause large strains in the gas diffusion layer (GDL), which results in significant changes in its mechanical, electrical and thermal properties. These changes affect the rates of mass, charge, and heat transport through the GDL, thus impacting fuel cell performance and lifet…
The aim of this project is to produce the thermal energy based upon the thermoelectric module (TEM), which is made up of two semiconductor metal junctions are used for heating and cooling process. The semiconductor element is made up of bismuth and tellurium. This process is carried out on the principle of peltier eff…
The grey cellulose (cotton) and regenerated cellulose (viscose rayon) fabrics of the same fabric particular were desized, scoured and bleached. Solvent treated under reflux and then dyed to the same shade with direct dye. The effect of solvent such as methanol, ethanol, propan-1-o1, chloroform, sodium hydroxide and wa…
Due to the unique optical properties like size-tunable emission color, narrow emission peak, and high luminescence efficiency semiconductor quantum dots (QDs) are emerging candidates for various applications. Size-controlled zinc sulfide (ZnS) and cadmium sulfide (CdS) quantum dots and their core/shell structures with…
Today the automotive market is pursuing lighter weight materials to reduce the overall weight of the vehicle. This is mainly due to the ever increasing demand to improve gas mileage. Past advances have shown that a lower density Sheet Molding Compound (SMC) based on fiberglass and polyester technology, can be manufact…
A new mechanism of fracture toughness enhancement in nanocrystalline materials and metal-ceramic nanocomposites is suggested. The mechanism represents the cooperative grain boundary sliding and nanograin nucleation (CGBSNN) process near the tips of growing cracks. It is shown that this mechanism can increase the criti…
Magnetic nanoparticles are used in medicine as drug delivery, imaging and therapeutic systems. Poly(lactic glycolic acid) (PLGA) is a biodegradable polymer that can be conjugated with poly(ethylene glycol (PEG) to prolong the circulation time. In this study, magnetic nanoparticles and the antineoplastic drug, Methotre…
Short cellulose nanofibrils (SCNF) were investigated as a reinforcement for polyvinyl alcohol (PVA) fibers. SCNF fibers were mechanically isolated from hard wood pulp after enzymatic pretreatment. Various levels of SCNF were added to PVA and gel-spun into continuous fibers. The molecular orientation of PVA was affecte…
An alcohol thermal route has been used to synthesiz e nanoparticles lead oxide at a low temperature of 75 °C. No surfactant/stabilizing agent was employed in th is method. The PbO samples were characterized by X-ray diffraction (XRD) employed to identify the st ructural phases. X-ray diffraction studies indicate the f…
The oscillatory behavior of CNT oscillators, initially subjected to bending, is studied under constant temperature using molecular dynamics simulations. We constrain the rotational motion of the inner CNT by imposing a small bending deformation to the initial structure. Our observation suggests that this constraint do…
