Free Cy5.5 dye and Cy5.5-labeled thermally cross-linked superparamagnetic iron oxide nanoparticles (TCL-SPION) have been routinely used for in vivo optical imaging. However, there is little information about the distribution and accumulation of free Cy5.5 dye and Cy5.5-labeled TCL-SPION in the tissues of mice. Free Cy…
Nonlinear optical single crystals of L-phenylalanine-4-nitrophenol have been grown by the slow evaporation method. The grown crystal was subjected to the single crystal X-ray diffraction analysis, to confirm that it belongs to the monoclinic crystal structure, with space group P21. The optical transmission study revea…
We present a hybrid method for simulating kinetic equations with multiscale phenomena in the context of linear transport. The method consists of (i) partitioning the kinetic equation into collisional and noncollisional components, (ii) applying a different numerical method to each component, and (iii) repartitioning t…
We performed direct numerical simulations of non-Brownian sedimenting particles, using a smooth profile method over a wide range of volume fractions from 0.01 to 0.5. We found that hydrodynamic velocity fluctuations scale as ϕ1/2, both parallel and perpendicular to gravity at low volume fractions (ϕ ≤ 0.04) due to ani…
The pyrolysis of phenolic-formaldehyde (PF) resin was studied by TG-MS technique. The structure changes of pyrolysis of PF resin heated to different temperatures were investigated by Fourier-transform infrared rays (FTIR). The experimental results shows that the pyrolysis of PF can be divided into three stages. Ether…
Different nanoclay concentrations (1–3 phr) were incorporated into an epoxy/carboxyl terminated poly(butadiene-co-acrylonitrile) liquid rubber (CTBN) blend to obtain epoxy/clay/CTBN nanocomposites. Morphological analysis (X-ray diffraction and electron microscopy techniques) of epoxy/clay/CTBN nanocomposites revealed…
The mechanism of gold nanowire (AuNW) and nanotube (AuNT) electrodeposition in a cyanide-free solution is investigated for the first time based on the analytical model of Szabo et al. (A.Szabo et al., J. Electroanal.Chem.217 (1987) 417) for recessed cylindrical ultramicroelectrode (UME).Track-etched Polycarbonate Temp…
We report here a simple yet efficient approach for fabricating large gold nanosheets using H2O2 as the reducing agent with starch as the stabilizer and shape-controlling agent. The weak reducing capability of H2O2 enables a kinetically controlled growth of nanosheets out of flower-like nanostructures formed at the ear…
Water oxidation is a key half reaction in the energy conversion scheme. The reaction mechanism for the oxidation of H2O to O2 catalyzed by single-Ru-substituted polyoxometalates, [Ru(III)(H2O)XW11O39](n-) (X = Si(IV), Ge(IV)), was investigated by means of density functional calculations. The electronic structure of th…
In this work, AgNPs and Van molecules were modified on the surface of LDH sheets via the reduction of Ag ions with glucose and the adsorption of Van. The products were characterized by high resolution transmission electron microscopy (HRTEM), energy dispersive spectroscopy (EDS) and Fourier-transform (FT-IR) spectrosc…
The synthesis of the novel copper(I) precursor [Cu(PPh3)2(O2CCH2OC2H4OC2H4OCH3)] and its application in the straightforward solution synthesis of oxide-free copper nanoparticles by mere thermal decomposition are reported; depending on the precursor concentration particles of sizes of 10 nm or 30 nm are obtained in nar…
The influence of temperature of oxalic acid on the formation of well‐ordered porous anodic alumina on Al‐0.5 wt% Mn alloys was studied. Porous anodic alumina has been produced on Al‐0.5 wt% Mn substrate by single‐step anodising at 50 V in 0.5 M oxalic acid at temperature ranged from 5°C to 25°C for 60 minutes. The ste…
Hexagonal WO3 nanostructures with controlled sizes and alignment ordering have been successfully realized on fluorine doped tin oxide (FTO) substrates with different pre-treatment methods by a hydrothermal approach. The effects of the pre-treatment conditions, such as pre-coating a layer of WO3 nanoparticles, the anne…
We study the nonequilibrium dynamics of multiband BCS superconductors subjected to ultrashort pump pulses. Using density-matrix theory, the time evolution of the Bogoliubov quasiparticle densities and the superconducting order parameters are computed as a function of pump pulse frequency, duration, and intensity. Focu…
Closely packed, size-controllable and stable Au nanohorns (AuNHs) that are difficult to synthesize through pure chemical reduction are facilely synthesized using a microorganism-mediated method in the presence of hexadecyltrimethylammonium chloride (CTAC). The results showed that the size of the as-synthesized AuNHs c…
We present a new pixel circuit on glass using hydrogenated amorphous silicon (a-Si:H) for driving polymer-stabilized blue-phase liquid crystal displays (BPLCDs). Different from conventional nematics, BPLC demands a large dielectric anisotropy in order to lower the operation voltage. As a result, the pixel's capacitanc…
New 8-quinolinolate (Q) complexes of yttrium (1) and ytterbium (2) were synthesized by the reactions of Cp3Y and Yb[N(SiMe3)2]3 with 3 equiv. of 8-hydroxyquinoline in a DME solution. Single crystal X-ray analysis revealed the trinuclear molecular structure of the compounds Ln3Q9. The LDI-TOFMS investigation displayed…
A series of Nb, W, N and F:TiO2 thin-film systems were grown by a combinatorial atmospheric pressure chemical vapour deposition (APCVD) process. Conditions were varied in each experiment to produce a series of films with compositional gradient. For each system, the electrical resistivity at a number of positions (up t…
This paper deals with the study on the effect of biological degradation to chemical composition and Fourier transform infrared (FT-IR) of sugar palm (Arenga pinnata) fibers obtained from different heights (1, 3, 5, 7, 9, 11, 13, and 15 m) of the sugar palm tree. It was observed that degradation that took place at the…
Sixteen new 3d–4f binuclear complexes have been obtained using two Schiff-base ligands, Hvalampy and Hvalaepy, derived from the reaction of o-vanillin and 2-aminomethyl-pyridine or 2-(2-aminoethyl)-pyridine, respectively. Hvalaepy ligand: [Zn(valaepy)2Sm(O2NO)3]·CH3CN 1; [Ni(valaepy)2Eu(O2NO)3(H2O)]·CH3CN 2; [Ni(valae…
