This study explored the improvement of physicochemical properties (mechanical resistance, water uptake, swelling, etc.) Nafion membranes by cellulose nanocrystals (CNCs). These composite were prepared from Ramie and Tunicate with respective aspect ratios about 28 106. It was demonstrated that, regardless type nanocrystals, increasing weight content 0 to 10 wt% increased uptake thickness swellin...

Polysaccharides from carrageenan have potential as bioplastics that is resistance to waters (hydrophobic), alsocan be improved by using modified starch. Modified starch a material can reduce the hydrophilic properties of bioplastics. The objectives this study were determine effect application on carrageenan-based bioplastic’s cup biodegradability and water best bioplastic formulation for resist...

The aim of this work was to study resistance helium accumulation processes in the structure surface layer lithium-containing ceramics and subsequent destruction embrittlement processes, depending on radiation fluence. objects were Li2TiO3-type obtained by thermal sintering. fluence dependency changes structural strength properties determined be range from 1018 1022 ion/m2, which corresponded co...

The main objective of the current research work is to explore effect nanosilica particles on compound EPDM/SBR-SiO2 (ethylene-propylene-diene monomer/styrene-butadiene rubber-nanosilica). composite EPDM/SBR with and without silane coupling agent was processed using an open mill mixer. are prepared in laboratory were used as reinforcing material rubber composites. cure characteristics, mechanica...

Vapor-phase synthesis techniques of polymeric nanostructures offer unique advantages over conventional, solution-based techniques because of their solventless nature. In this work, we report the fabrication of coaxial polymer nanotubes using two different chemical vapor deposition methods. The fabrication process involves the deposition of an outer layer of the conductive polyaniline (PANI) by ...

P-glycoprotein (P-gp), the product of the human multidrug resistance (MDR1) gene, confers multidrug resistance on cells by acting as an ATP-dependent drug transporter. A method using confocal microscopy was developed to measure the transport activity of P-gp from the rate of movement of doxorubicin, a fluorescent substrate of P-gp, across the membrane of a single cell. Recent work has shown tha...

Norway spruce (Picea abies (L.) Karst.) trees were preinoculated with a sublethal dose of the blue-stain fungus Ceratocystis polonica Siem. (C. Moreau) 1 to 52 weeks before they were mass inoculated with the same fungus. Trees pretreated 1 week before mass inoculation had similar, severe symptoms of fungal infection as the control trees. Pretreatment 3, 6 or 9 weeks before mass inoculation resu...

Four types of Shiraz inlay (Khatam) samples were impregnated with nano-silver solution via spraying (S), a vacuum desiccator (VD), and immersion/dipping (I/D) for 2 h 24 techniques. The decay resistance dimensional stability evaluated after each treatment. specimens exposed to white-rot fungus 10 weeks by the agar-plate method, weight loss was determined assess decay. soaking in water measured....

Bipolaris maydis race T toxin (BmT), and its functional analog, methomyl, uncoupled Texas male-sterile (T) cytoplasm mitochondria by decreasing the resistance of the inner membrane to protons. However, unlike protonophoric or ionophoric agents, BmT toxin and methomyl induced irreversible swelling. Packed volume measurements showed that mitochondrial volume was irreversibly increased by methomyl...
