Electronic (β(e)) and vibrational (β(v)) first-order hyperpolarizabilities of uracil were determined in gas and water solution using the Coulomb-attenuating Density Functional Theory level with the Dunning's correlation-consistent aug-cc-pVDZ basis set. Frequency-dependent β(e) values were computed for the Second Harm…
Effective prediction of calcite scaling requires a reliable thermodynamic model for the prediction of the scaling tendency, a kinetic model for the prediction of scaling rate and a transport model to simulate flow in a porous medium. The accurate prediction of the scale deposition can warn the engineers to “treat” the…
Mixed alkali tungsten borate glasses xLi2O–(30–x) K2O–10WO3–60B2O3 (0 < x < 30) were prepared from the melts. These glasses were characterized using X-ray diffraction, differential scanning calorimetry and density measurements. Optical absorption studies were carried out as a function of alkali content to look for mix…
The resistance of several pristine and functional single‐wall carbon nanotubes (SWNTs) deposited and dried on interdigitated electrode (IDE) chips was investigated to better understand how functional groups influence their resistivity. Without the external electrical field, the resistance was generally increased for t…
In this study, bast fibers of kenaf (Hibiscus cannabinus L.), in the form of randomly dispersed short-fiber reinforcement, were loaded into poly(lactic acid) (PLA) or simply polylactide. Twin-bladed melt mixing followed by hot-pressing was chosen as the present composite molding with fiber weight fractions varied from…
Resveratrol (3,5,4′–trihydroxy–trans–stilbene, RSV), is found in various plants, including grapes, berries and peanuts. It is also present in wines, especially red wines. RSV has potent antioxidant, anti–inflammatory, and chemo–protective properties used as a biologically active supplement in the prophylaxis of myocar…
Glasses with composition 20B2O3.(79.5-x)Bi2O3.xSiO2 (10 ≤ x ≤ 40) containing 0.5mol% of Er3+ ions were prepared by melt-quench technique. Optical absorption and fluorescence spectra were recorded at room temperature for all glass samples. Based on the Judd-Offelt theory, spectroscopic properties of Er3+ ions are discu…
We investigate the plasmonic resonant spectrum of gold single nanotorus and nanoring and the corresponding dimers. Dimer nanoring structures is characterized narrower line width and higher Purcell factor, making it suitable for high sensitivity sensing.
In this study, a complex-mediated synthetic growth method was used to embed silver (Ag) nanoparticles in poly(vinyl alcohol) (PVAI) nanofibers in an aqueous solution. Azobisisobutyronitrile (AIBN) played a pivotal role in the preparation of the Ag–PVAI nanofibers, via its cyano groups. AIBN was used to assemble the Ag…
Vertically aligned carbon nanotube field-effect transistors (CNTFETs) have been experimentally demonstrated (J. Li et al., Carbon, 2012, 50, 4628-4632). The source and drain contact heights in vertical CNTFETs could be much higher than in flat CNTFETs if the fabrication process is not optimized. To understand the impa…
Novel type of polyethylene imine having methoxy (–OCH3) substituent azobenzene side chain group through eight methylene spacer group (PEI8M) was successfully synthesized and characterized by the polymer by 1H NMR, differential scanning calorimetry, polarized optical microscopic and X-ray diffraction analysis. Synthesi…
Ferroelectrics (Ba0.92−xCa0.08Ndx)(Ti0.82Zr0.18)O3 (0 ≤ x ≤ 0.02) were prepared through conventional sintering route. The influence of Nd3+ dopant on dielectric properties and crystal chemistry of (Ba0.92Ca0.08)(Ti0.82Zr0.18)O3 have been studied. The XRD analysis suggested that the second phase occurred until x = 0.01…
Titanium diselenide (TiSe2) alloy was prepared using solid state reaction method and hot press sintering. The effects of hot press sintering temperatures on TiSe2 were studied on the thermal transport properties of the material. As grown material shows pure TiSe2 phase and layer structure. Increasing sintering tempera…
In this report direct photo-induced formation of surface relief gratings (SRG) in thin layers of arsenic sulfide (As2S3) are shown. This anisotropic light-induced mass transfer phenomenon has been discussed with the special attention focused on the polarization and intensity of the corresponding light. The experimenta…
We have attempted a green alternative to reuse the spent fluid catalytic cracking (FCC) catalyst that is used in petroleum refining industry for the upgradation and purification of various petroleum streams and residues. The spent FCC zeolite–based catalyst modified by enhancing the acidic properties by incorporating…
Tungsten is one of the candidate materials being considered for fabricating the plasma facing components (PFCs) of fusion reactors. When used in fusion reactors, PFCs are exposed to high heat loads from the fusion plasma, resulting in the PFCs being subjected to induced thermal stresses. This study focused on the cree…
Tribological properties of a vertically aligned carbon nanotube (CNT) film with a thickness of approximately 700 μm under millinewton and micronewton level loads were investigated using a 1 mm radius ball. At the beginning of frictional slidings, friction forces were high, and then decreased and seemed to reach relati…
Long chain phosphate esters bearing at least one or two aryl groups have been synthesized and used for the preparation of stable multi-walled carbon nanotube (MWCNT) hybrids. The non-covalent interaction ester/MWCNT has been investigated by several techniques (SEM, UV-vis, 31P-NMR, RAMAN). The used phosphate ester der…
The capability of natural and modified-Illite/kaolinite for zinc adsorption from aqueous solution was investigated in the present paper. The new hybrid material was composed of the natural clay using the intercalation process with dimethyl sulfoxide. The objective of this study was to examine the adsorption behavior o…
This study investigates the effects of varying the spiked iron content of iron/carbon nanopowder (Fe/CNP) composite materials on hydrogen storage capacity. Among four such samples, a maximum hydrogen uptake of approximately 0.48 wt% was obtained with 14 wt% of spiked iron under 37 atm and 300 K. This higher hydrogen u…
