Current-voltage characteristics and DC electrical conductivity were studied for Ge30-xSe70Snx (x = 8, 11, 14, 17 and 20) glassy thin pellets of diameter 12mm and thickness 1mm prepared under a constant load of 5 tons using a well-known melt quenching technique in bulk as a function of composition. The I-V characterist…
There is a real need for a device which is capable of detecting low levels of H 2 ranging from 0.1 ppm to 100 ppm for applications involving leak detection in hydrogen fuel storage systems. Due to its versatile properties, ZnO thin films are good candidate for hydrogen gas detection. This research addresses the H 2 ga…
A new π-extended tetrathiafulvalene analogue capable of reversibly revealing and concealing a central pentacene segment under redox control was synthesized and characterized by various spectroscopic and electrochemical analyses and DFT calculations.
Y 2.94− x Al 5 O 12 (YAG):Ce 0.06 Pr x phosphors with various Pr 3+ concentrations ( x = 0, 0.006, 0.01, 0.03, 0.06, and 0.09) were synthesized by using a coprecipitation method. The phases, luminescent properties, and energy transfer phenomenon from Ce 3+ to Pr 3+ were investigated. The results indicated that the dop…
In the present investigation, PLA porous scaffolds was fabricated using NaCl as porogen in three different solvents i.e. 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), dichloromethane (DCM) and chloroform (CF) respectively, by solvent casting particulate leaching method. The morphology, structure and thermal behaviour of t…
Well-defined block copolymers containing furan groups were anionically synthesized in the presence of NaBPh <sub>4</sub> and used for the formation of thermoreversible networks <italic>via</italic> a Diels–Alder click reaction.
The interfacial and structural properties of fluids confined by surfaces of different geometries are studied at the mesoscopic scale using dissipative particle dynamics simulations in the grand canonical ensemble. The structure of the surfaces is modeled by a simple function, which allows us to simulate readily differ…
ZnS quantum dots were synthetized at room temperature using a simple photochemical process involving ketyl radicals. Through the simple adjustment of reagent concentration, the method allows the control of nanoparticle size. Transmission electron microscopy confirmed that the nanomaterial adopts the hexagonal structur…
Polyethylene glycol enhances the accuracy of drug delivery system evaluations by preventing sorptive losses of hydrophobic drugs to plastic reaction vessels.
A small amount of IRGO sheets can largely decelerate the dissolution of cellulose in AmimCl, and the mechanical properties of the regenerated cellulose/graphene nanocomposites materials can be tuned by the dissolution time.
Graphene's impact on future applications is intimately linked to advances in the synthesis of high quality materials. Chemical vapor deposition (CVD) shows great potential in this area but insufficient connectivity between single-crystalline domains deteriorates the achievable electrical and mechanical performance. We…
In a recent study by Voliani et al. [Small, 2011, 7, 3271], the electromagnetic field enhancement in the vicinity of the gold nanoparticle surface has been exploited to achieve photocontrolled release of a molecular cargo conjugated to the nanoparticles via 1,2,3-triazole, a photocleavable moiety. The aim of the prese…
This paper describes the green synthesis of core–shell silver nano/micro particles (AgNP/MPs) using poly (vinyl alcohol) (PVA) and tamarind kernel powder (TKP) as reducing cum stabilizing agents. Effect of both mean hydrodynamic sizes and zeta potentials of the polymeric reactants on size and stability of silver parti…
V and Ti atoms incorporated into the framework of MCM-41 in the form of tetrahedral coordination with excellent catalytic performance.
A sandwich-type dimer, namely (μ-oxo)bis[tetrakis(p-bromophenyl-porphyrinato)iron(III)], [(TBPP)Fe]2O, was prepared under solvothermal conditions and structurally characterized for the first time. Its self-assembly behavior has been comparatively investigated with the monomer [(TBPP)Fe]Cl by electronic absorption spec…
The use of H3L (= 2-(β-naphthalideneamino)-2-hydroxymethyl-1-propanol) in mixed-metal manganese-lanthanide carboxylate cluster chemistry has led to the isolation of two new dodecametallic heteronuclear isostructural [Mn6(III)Ln6(III)] complexes (Ln = Gd, Dy), with the Dy analogue displaying temperature and frequency d…
Superparamagnetic iron oxide nanoparticles with a wide size range (2.6-14.1 nm) were synthesized and coated with the amphiphilic poly(amidoamine) PAMAM-C12 dendrimer. The resulting well dispersed and stable water suspensions were fully characterized in order to explore their possible use in biomedical applications. Th…
A tungsten/epoxy composite film integrated with graphene oxide (GO) is prepared <italic>via</italic> a layer-by-layer assembly method, which shows enhanced acoustic attenuating performance compared with a tungsten/epoxy composite film in the absence of GO.
We present sonogenerated magnesium-hydrogen sponges for effective reactive hard templating. Formation of differently organized nanomaterials is possible by variation of sonochemical parameters and solution composition: Fe2O3 nanorods or composite dendritic Fe2O3/Fe3O4 nanostructures.
In this work, we investigate the shape, microstructure and thermal response upon heat treatment of Co-based NPs inside CNTs.
