We report the putative Global Minimum (GM) structures and electronic properties of Ga(N)(+), Ga(N) and Ga(N)(-) clusters with N = 13-37 atoms, obtained from first-principles density functional theory structural optimizations. The calculations include spin polarization and employ an exchange-correlation functional whic…
To evaluate to efficacy of silver and gold generated larvicide with the help of entomopathogenic fungus Chrysosporium tropicum against the Culex quinquefasciatus and Anopheles stephensi larvae. The silver and gold nanoparticles were quantified and observed by the Micro-scan reader and X-ray diffraction technique. The…
Adsorption of uncharged homopolymers in good and theta solvents onto planar surfaces at various chain flexibility and polymer–surface attraction strengths was investigated by using a coarse-grained bead–spring polymer model and simulation techniques. Equilibrium properties of the interfacial systems were obtained from…
Using the dual thin layer flow through cell, a semi-quantitative analysis of the volatile products during the electrooxidation of adsorbed and bulk solution of 0.01 M ethanol at polycrystalline platinum, smooth, roughened and Sn modified Pt(11,1,1), Pt(311) electrodes has been done by on-line differential electrochemi…
Mesocellular carbon foam (MSU-F-C) is functionalized with hollow nanographite by a simple solution-phase method to enhance the intrapenetrating electrical percolation network. The electrical conductivity of the resulting material, denoted as MSU-F-C-G, is increased by a factor of 20.5 compared with the pristine MSU-F-…
New TTF-based (TTF = tetrathiafulvalene) ligands, L1 and L2 (L1 = α-(4'-methyl-4,5-ethylenedithiotetrathiafulvalene-5'-thio)-α'-[tris-2,2,2-(1-pyrazolyl)ethoxy]-p-xylene and L2 = α-(4'-methyl-4,5-dimethylthiotetrathiafulvalene-5'-thio)-α'-[tris-2,2,2-(1-pyrazolyl)ethoxy]-p-xylene), possessing tris-pyrazolyl coordinati…
A novel thiol-functionalized PCL (PCL-HDT) was synthesized following a convenient two-step procedure. Taking advantage of the pendant thiol group, degradable elastomeric materials have been prepared from PCL-HDT by redox or thiol–ene reaction. Elastomers were characterized by HRMAS NMR spectroscopy to confirm the form…
Organic peroxides are a kind of very hazardous substance because they are capable of self-decomposition when being heated or exposed to the sunlight. In present paper, the thermal hazard of tert-butyl hydroperoxide (TBHP) has been investigated by using accelerating rate calorimeter (ARC). On the basis of experimental…
Image guided technique is playing an increasingly important role in the investigation of the biodistribution and pharmacokinetics of drugs or drug delivery systems. The application of these new materials and techniques with combined properties of diagnosis and therapy can benefit the development of targeted drug deliv…
A facile method to produce dextran-coated gold nanoparticles (DGNPs) for atherosclerosis detection using computed tomography (CT) imaging is developed. DGNPs are prepared using only pyrenyl dextran as a reducible stabilizer chemically conjugated with hydroxyl groups of dextran and carboxyl groups of pyrenyl molecules,…
Carbon dioxide foaming in polymeric materials has been recognized as an environmentally friendly method to introduce microfoam consisting of cells of micrometre size (microcells). Our group has demonstrated that CO2-philic fluorinated block domains of block copolymers worked as nuclei of foams and further decreased th…
Two series of Yb 3+ -doped silica glasses (YA and YAP) are fabricated using the sol-gel method, and their spectroscopic properties are investigated. The longest fluorescence lifetime of 0.96 ms is obtained in YAP2 and YAP3 glasses. The emission cross-section (emi) and emi of Yb 3+ in the YAP1 glass are 1.00 pm 2 and 0…
The present work highlights the importance, in nuclear fuel safety and performance, of the very high oxygen potentials of actinide oxides (ThO2, UO2, NpO2, PuO2) at temperatures close to melting (around 3000 K), i.e. a tendency to oxidize their environment and chemically react with it.Laser heating coupled with fast p…
Conformity between macro-mechanics and microscopic functions of hydrogen in failure is reviewed in reference to some models of hydrogen embrittlement (HE), focusing on the role of plasticity. Plastic strain localization, a characteristic feature of HE, is consistent with the hydrogen-enhanced creation of vacancies dur…
Functional peptides play an important role in the formation of biominerals. Here we focus on peptides involved in mineralization of the exoskeleton of a crayfish. New recombinant peptides are designed and synthesized on the basis of an acidic functional peptide, CAP-1, derived from the exoskeleton of a crayfish. We ha…
The development of a simple and feasible method to synthesize Au nanoarchitectures with branched shapes is highly desired and technically important for the exciting anisotropic Au structures which are useful in diverse research fields. In this study, a one-step and rapid strategy is developed to selectively synthesize…
The encapsulation of aqueous and organic solvents with particles used to form liquid marbles implies there are attractive interactions between the particles and those different liquids. This is often masked, however, by the impact of the droplet kinetic energy on marble formation. We investigated droplet wetting and e…
Halloysite clay nanotubes were used as a support for the immobilization of the enzyme peroxidase from clover sprouts (Trifolium), and employed together with platinum nanoparticles in 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquid (Pt-BMI·PF(6)) in the development of a new biosensor for the determination…
The potential of organic–inorganic liposomal cerasomes to store and release doxorubicin (DOX) is investigated. Specifically, cerasomes display sustained DOX release in serum-enriched cell culture medium but minimal drug leakage in deionized water. As revealed by a physics-based model, the medium-sensitive DOX release/…
Glass samples with the composition 2SrO·TiO2·2.75 SiO2 were polished, subsequently covered with graphite or alumina powder and finally annealed at 970 °C for 20 h in order to induce surface crystallisation. The effect of the surface treatment on the preferred crystal orientations during growth into the bulk is analyze…
