Alloy CdTe(1-x)Se(x) quantum dots (QDs) have been fabricated by an organic route using Cd, Te and Se precursors in a mixture of trioctylamine and octadecylphosphonic acid at 280 °C. The variation of photoluminescence (PL) peak wavelength of the CdTe(1-x)Se(x) QDs compared with CdTe QDs confirmed the formation of an al…
Effects of operating parameters such as hydraulic retention time(HRT), recycle ratio and influent COD concentration on the performance of a continuous flow microbial fuel cell(MFC) were investigated. Decrease of HRT improved mass transfer of substrate to electrogenic microorganisms, therefore resulting in increased el…
The highly selective conversion of biomass-derived fructose into 5-hydroxymethylfurfural (HMF) can be achieved through the use of a tailored nanocomposite catalyst. In their Communication on page 10349 ff., S. L. Scott, J. A. Dumesic, et al. describe a simple and effective method for manipulating the reaction microenv…
Eight different complexes with three positional isomeric dipyridyl ligands (3,3'-Hbpt, 3,4'-Hbpt, and 4,4'-Hbpt) (here, 3,3'-Hbpt = 1H-3,5-bis(3-pyridyl)-1,2,4-triazole, 3,4'-Hbpt = 1H-3-(3-pyridyl)-5-(4-pyridyl)-1,2,4-triazole, and 4,4'-Hbpt = 1H-3,5-bis(4-pyridyl)-1,2,4-triazole), as well as 3,3',4,4'-biphenyltetrac…
We investigate channel-length scaling characteristics for effects of a single charged defect in a carbon nanotube field-effect transistor (CNFET), using the nonequilibrium Greens function method. We find that the threshold voltage shift due to a single charge in midchannel increases with the decreasing channel length.…

In this study, the effect of laser shock peening on a titanium alloy was modeled using different confinements. Both liquid and solid confinement could be applied to laser shock peening, and solid confinement provided a dry laser shock peening process, which has the advantage of a corrosion-free effect. When a differen…
We directly visualized the uptake and intracellular vesicle transport of shortened single walled carbon nanotubes in living cells through a dual-labeling system. With a stable labeling of fluorescein isothiocyanate and a pH-sensitive stacking of doxorubicin on carbon nanotubes, the location of internalized nanotubes i…
The compound 4-methyl (2′-hydroxy,4′-n-hexadecyloxy) azobenzene was synthesized by Prajapati and co-workers (Mol. Cryst. Liq. Cryst. 369 (2001), pp. 37–46). Subsequent experiments (D. Pal, [PhD thesis], University of Lucknow, Lucknow, India, 2007) confirmed that the compound exists in nematic phase for a small range o…
Abstract Abstract. The metal organic framework, [Cu5(C5H2N2O3)4(H2O)4(NO3)2·10H2O]n (1), was synthesized by a hydrothermal reaction via copper nitrate and in situ generated 3‐hydroxopyrazine‐2‐carboxylate from 3‐aminopyrazine‐2‐carboxylic acid. Compound 1 was characterized by elemental analysis, infrared spectroscopy,…
The experimental protocol is based on a green wood slice in Douglas fir with a thickness of 30 mm just peeled, Figure 1(a). In this picture, the left side of the slice corresponding to the hardwood region, and the right side represents the normal wood. The preparation of the specimen consists on draw black marks accor…
The pitting potentials of F1-5 are shown in Fig. 1. It can be seen that the corrosion resistance of F1-5 improve with the increase of chromium content, and molybdenum added F5 shows a superior corrosion resistance to that of 304. At the same chromium content level, F2 with low carbon and nitrogen contents has a better…
The solution of the nonhomogeneous first order differential equation (6) is: 3 VERIFICATION OF RESULTS The recommended approach for determining the crack width is verified against experimental results to judge how the recommended approach can be applied for design practice.The test results obtained by (Ghattas 1994),…
In case of standard reinforced concrete systems with rigid joints the effective reinforcement of the prefabricated system in the part with joints is of utmost importance for energy dissipation through plastic deformation of joints of prefabricated units. The type, quality and amount of reinforcement are vital for reac…
PVA and steel fibres with a total volume fraction of 2%. The detail mix data is presented in Table 1. The quantities are expressed as mass ratios relative to the mass of cement. Cylinders of 100 mm diameter and 200 mm high were cast and tested for their elastic modulus, both at hot state and after cooling to room temp…
Electrodeposition as a kind of significant electrochemical technique was used to prepare CoPtMo magnetic materials on copper substrate from an alkaline electrolyte. The influence of hypophosphite addition on the deposition process, alloy content, microstructure and magnetic properties of CoPtMo thin films was studied.…
