We synthesized the Eu3+ activated SrWO4 nanocrystalline microspheres by a simple and facile synthesis route. X-ray diffraction patterns exhibited a unique phase of SrWO4:Eu3+ scheelite structure with an average crystallite size of 58.9 nm. Fourier transform infrared spectra revealed the presence of absorption bands of…
During the current investigation, alkali treated Palmyra palm leaf stalk fiber (PPLSF) and jute fibers were chosen as reinforcement for the unsaturated polyester matrix. Layering patterns such as bi-layer (PPLSF/jute) and tri-layer (PPLSF/jute/PPLSF and jute/PPLSF/jute) were chosen, and composites were fabricated by h…
Bereit zum Beladen: Gepackte Siliciumdioxid-Nanoröhren, die mithilfe der Titelmethode assembliert wurden, dienten als Träger für die Beladung mit Goldnanopartikeln. Die erhaltenen Kompositmaterialien katalysieren die Epoxidierung von Styrol zu Styroloxid mit hohem Umsatz und hoher Selektivität.
In this work, a combination of nanoparticles of Nd2Fe14B hard magnetic phase and alpha-Fe soft magnetic phase were synthesized by one pot chemical synthesis technique using sol-gel method. A gel of Nd-Fe-B was prepared using NdCl3 x 6H2O, FeCl3 x 6H2O, H3BO3, citric acid, and ethylene glycol by pechini type sol-gel me…
Coordinating ligands are widely used to vary the solubility and reactivity of nanoparticles for subsequent bioconjugation. Although long-term colloidal stability is enhanced by using bidentate coordinating ligands over monodentate ones, other properties such as nonspecific adsorption of target molecules and ligand exc…
We study the effect of confinement on glassy liquids using random first order transition theory as a framework. We show that the characteristic length scale above which confinement effects become negligible is related to the point-to-set length scale introduced to measure the spatial extent of amorphous order in super…
Polyhydroxyalkanoates (PHAs) are polyesters of hydroxyacids naturally synthesized in bacteria as a carbon reserves. Bacillus subtilis can synthesize and accumulate PHA as carbon source under limiting conditions of nutrients. PHAs are promising candidates for the development of environment-friendly, biodegradable plast…
We propose a numerical method to evaluate the two-photon-induced luminescence (TPL) of single gold nanorods (GNRs). The validity of this method is confirmed by the cos 4 α dependence of the TPL of single GNRs on the polarization angle α, which is in good agreement with experimental observations. As comparing with thei…
The giant optical nonlocality near the Dirac point in lossless metal-dielectric multilayer metamaterials is revealed and investigated through the analysis of the band structure of the multilayer stack in the three-dimensional ω-k space, according to the transfer-matrix method with the optical nonlocal effect. The posi…
In this paper, controllable synthesis of various ZnO nanostructures was achieved via a simple and cost-effective hydrothermal process on the Si substrate. The morphology evolution of the ZnO nanostructures was well monitored by tuning hydrothermal growth parameters, such as the seed layer, solution concentration, reac…
We monitor effective band gap energy shifts and free reagent concentration during the formation of CdS shells on CdSe nanocrystals to test the hypothesis that alternating addition of stoichiometric doses of precursors can effectively saturate surface sites and thereby enforce conformal shell growth. The selective ioni…
We report the growth of vertically aligned indium-doped ZnO (IZO) nanorods on a glass substrate using a low-temperature hydrothermal method. An IZO nanorod metal-semiconductor-metal (MSM) ultraviolet (UV) photodetector (PD) was also fabricated. It was found that the UV-to-visible rejection ratio of the fabricated PD w…
Softness of apparel textiles is a major attribute sought by consumers. There is surprisingly little objective information on the softness properties of rare animal fibres, particularly cashmere, alpaca and mohair. Samples of these and other rare animal fibres from different origins of production and processors were ob…
A series of luminescent complexes based on {Ir(phpy)2} (phpy = cyclometallating anion of 2-phenylpyridine) or {Ir(F2phpy)2} [F2phpy = cyclometallating anion of 2-(2',4'-difluorophenyl)pyridine] units, with an additional 3-(2-pyridyl)-pyrazole (pypz) ligand, have been prepared; fluorination of the phenylpyridine ligand…
Recently, two-dimensional (2D) nanomaterials have received huge attention because of their attractiveness for use in many electronic and optoelectronic devices. Graphene is the two-dimensional basic building block for carbon allotropes of any dimensionality, such as graphite, nanotubes and fullerenes. As we know, tran…
This work demonstrates an anisotropic increase in resistivity with decreasing width in single crystal tungsten (W) nanowires having a height of 21 nm. Nanowire-widths were in the range of 15-451 nm, with the anisotropy observed for widths below 50 nm. The longitudinal directions of the nanowires coincided with the <10…
The Arabidopsis protein AtTTM3 belongs to the CYTH superfamily named after its two founding members, the CyaB adenylate cyclase from Aeromonas hydrophila and the mammalian thiamine triphosphatase. In this study we report the three-dimensional structure of a plant CYTH domain protein, AtTTM3, determined at 1.9 Å resolu…
The road to the realization of complex integrated circuits based on graphene remains an open issue so far. Current graphene based integrated circuits are limited by low integration depth and significant doping variations, representing major road blocks for the success of graphene in future electronic devices. Here we…
PURPOSE: Gold nanorods have the potential to enhance the treatment efficacy of interstitial photothermal therapy. In order to enhance both the potential efficiency and the safety of such procedures, treatment planning on laser power density, nanoparticle concentration, and exposure time has turned out to be useful in…
The line tension for a Lennard–Jones (LJ) fluid on a (9, 3) solid of varying strength was calculated using Monte Carlo simulations. A new perturbation method was used to determine the interfacial tension between liquid–vapour, solid–liquid and solid–vapour phases for this system to determine the Young's equation conta…
