The synthesis and characterization of vesicles assembled from deep cavitands in water is reported. These vesicles act as hosts for three different types of guests: the cavitands bind small guest molecules, the bilayer attracts larger hydrophobic guests and the inner aqueous compartment contains hydrophilic molecules.
Magnetite nanoparticles with hydrophilic surface coating are prepared in polyamine solvents. The resulting products are highly stable in polar solvent. The surface amine groups are available for secondary reactions.
Searching for suitable platinum-free electrocatalysts toward novel iodine-free redox couples is of vital importance for further cost reduction and large-scale implementation of dye-sensitized solar cells (DSCs). Herein, cross-stacked superaligned carbon nanotube (CSCNT) sheets were incorporated as efficient economical…
Resistive random access memory (RRAM) combines the advantages of nonvolatile flash memory and volatile dynamic random access memory, avoiding their drawbacks. For the practical use of RRAM, achieving low-voltage driving is strongly desired. Here we report the effect of Ni nanoparticles on solution-processed NiO based…
An anion receptor combined different types of hydrogen bond donors such as OH, NH and CH groups has been synthesized. By rotation of the sub methyl group, this receptor showed evident (1)H NMR response to both fluoride and sulfate, while colorimetric and fluorescent responses were only observed in the presence of fluo…
A new method for quenching kinetic discrimination of Fe(2+) and Fe(3+), and sensitive detection of trace amount of Fe(2+) was developed by using synchronous fluorescence scan technique. The principle of this assay is based on the quenching kinetic discrimination of Fe(2+) and Fe(3+) in CePO(4):Tb(3+) nanocrytals-H(2)O…
The development and application of nitride-based light-emitting diodes (LEDs) is hindered by the low hole conductivity of Mg-doped layers. As an alternative, polarization-induced hole doping of graded p-AlGaN layers was recently demonstrated. Using previously manufactured 440nm LEDs as device examples, this paper eval…
We investigated the electronic structure of Fe nanoparticle-graphene composites and the impact of the interfacial interaction on NH(x) (x = 0, 1, 2, 3) adsorption by first-principles based calculations. We found that Fe(13) nanoparticles can be stabilized by the sp(2) dangling bonds on single vacancy graphene substrat…
The efficacy of compression therapy using compression bandages is highly dependent on the level of compression applied and the sustenance of the pressure during the course of treatment. This study attempts to predict the pressure profile generated by compression bandages using constitutive equations describing relaxat…
Sugarcane products represent an abundant and relatively low cost carbon resource that can be utilised to produce chemical intermediates such as levulinic acid and furanics. These chemicals can be easily upgraded to commodity and specialty chemicals and biofuels by high yielding and well established technologies. Howev…

Interfacial properties at the photoelectrode of dye-sensitized solar cell (DSSC) play a vital role in determining its efficiency. This research examined the role of annealing temperature on the photoelectrode interfaces properties, and to find the annealing temperature that provides the highest overall solar cell effi…
Abstract ZnO nanorods with different sizes and shapes have been successfully synthesized via a simple hydrothermal route, using zinc acetate and Cetyltriammonium bromide (CTAB) as the reactants. The thick films of as prepared ZnO were prepared by screen-printing technique in desired pattern. The films are characterize…
Currently, there is a growing need to develop environmentally benign nanoparticle synthesis process that does not use toxic chemicals in the synthesis protocols. Synthesis of nanomaterials by biological approach is innovative, cheaper and environmental friendly and requires lesslabor. In this regard, the present study…
Physical hydrogels based on poly (vinyl alcohol) (PVA) were synthesized in the presence of natural polysaccharides, either hyaluronan or Chondroitin sulphate, in order to obtain versatile biomaterials with enhanced performances. The physical network is obtained by the freeze thawing technique, a simple method widely u…
The Ordinary Portland Cement (OPC) is one of the main ingredients used for the production of concrete. Unfortunately, production of cement involves emission of large amounts of carbon-dioxide gas into the atmosphere, a major contributor for green house effect and the global warming, hence it is inevitable either to se…
The surface free energy of a solid is a material property that influences its interaction with other solids, liquids, and gases. Mineral aggregates are mixed with bitumen in the production of asphalt mixtures, and the interaction of aggregates with bitumen, water, or chemical modifiers affects the overall performance…
(15)N and (13)C NMR experiments were applied to conduct a comparative study of a cold shock protein (Csp) in two states-lyophilized powder and a protein embedded in a glassy trehalose matrix. Both samples were studied at various levels of rehydration. The experiments used (measuring relaxation rates R(1) and R(1ρ), mo…
Multiwalled carbon nanotubes (MWCNTs) are functionalized with phosphomolybdic acid (PMo) by ultrasonication. With the assistance of PMo, PtIr nanoparticles are homogeneously dispersed on the surface of MWCNTs. The size of PtIr nanoparticles can be controlled from 1.6 to 3.2 nm by tuning the composition of Pt catalysts…
A new 3D coordination polymer was solvothermally synthesized. The coordination polymer possesses a lon network built from 4-connecting Co2 clusters and tetracarboxylate ligands, and exhibits selective gas sorption behavior as well as antiferromagnetic interactions.
