A fractal method was introduced to quantitatively characterize the dispersibility of modified kaolinite (MK) and precipitated silica (PS) in styrene–butadiene rubber (SBR) matrix based on the lower magnification transmission electron microscopic images. The fractal dimension (FD) is greater, and the dispersion is wors…
This research study was aimed at determining the temperature dependence of Ferromagnetic Resonance (FMR), the recorded signal versus angle and the magnetic property of the 15 uc thick La0.7Sr0.3MnO3 (LSMO) thin film sample on a single crystalline SrTiO3 (STO) substrate at 150 K and 9.75 GHz using ferromagnetic resonan…
The roots of Hemidesmus indicus R.Br. was collected from Maruthamalai hills, Coimbatore and were extracted with 90% ethanol and fractionated by column chromatography using different solvents. A phytochemical Terpenoid was isolated using thin layer chromatography. The infrared spectrum was used for characterization of…
In the past, decennia radiation-induced radicals were successfully identified by electron magnetic resonance (EMR) in several solid-state amino acids and sugars. The authors present a room temperature (RT) EMR study of the stable radicals produced by X-ray-irradiation in the amino acid l-threonine (CH₃CH(OH)CH(NH₃ (+)…
Abstract Unfunctionalized mesocellular foam of silica was used for immobilization of the lipase from Thermomyces lanuginosus. In the first approach, lipase was adsorbed onto polyethyleneimine-coated Fe3O4 nanoparticles, and these particles in turn were bound to the foam interior to obtain the immobilized preparation […
The effect of imposed time-periodic boundary temperature of small amplitude on electroconvection under AC electric field in dielectric couple stress liquids is investigated by making a linear stability analysis. A regular perturbation method is used to arrive at an expression for the correction Rayleigh number that th…
Pressure techniques or Focussed forces like sonic pulses, voltage pulses, ballistic treatment or optoporation by Laser beam and use of penetration enhancers are more often invasive to overcome the multiple barrier function of skin. Now, the colloidal systems are getting preference to be used transdermally. The colloid…
Partial oxidation of methane to synthesis gas (a mixture of H2 and CO) over 5 wt.% Ni/CeO2 catalysts has been studied in a fixed bed down flow reactor. The catalyst has been characterized by XRD, N2-sorption, SEM, TEM, ICP-AES and XPS data. It is found that the Ni-CeO2 catalyst can activate methane at 500 oC, and with…
Poly(3,4‐ethylenedioxythiophene)/poly(styrenesulfonate)/antimony‐doped tin oxide (PEDOT/PSS/ATO) nanocomposite microspheres with the size range from 10 to 50 µm have been prepared by a solution mixing and self‐assembling method in the presence of ammonium persulfate. The transparent PEDOT/PSS/ATO nanocomposites were p…
Tri-reforming of glycerol has been carried out, for the first time, on CeO2, ZrO2 and CeO2-ZrO2 supported 10 wt.% Ni catalysts. The catalysts have been characterized by nitrogen adsorption, X-ray diffraction, temperature programmed reduction, scanning electron microscopy, Raman spectroscopy and X-ray photoelectron spe…
The chemical synthesis is described of a polypeptide construct possessing both the variable and the collagen-like domain of adiponectin, which can be used as a model system for probing the influence of the variable domain on multimerization of this important circulating hormone. Using a collagen domain repeat peptide…
We present an ab-initio investigation of the structural, electronic, and optical properties of substitutional nitrogen doping of a-TiO2. Through observation of multiple N-doped amorphous structures, we find additional localized tail states within the band gap. Some structures show these states nearly 1 eV above the va…
Indium doped zinc oxide hierarchical nanostructures have been synthesized using a simple aqueous solution based method. A change in morphology from hierarchical nanostructures in ZnO to nanorods after doping with indium has been observed. The optical properties of nanostructures have been investigated using diffuse re…
Replication factor C (RFC) is known to function in loading proliferating cell nuclear antigen (PCNA) onto primed DNA, allowing PCNA to tether DNA polymerase for highly processive DNA synthesis in eukaryotic and archaeal replication. In this report, we show that an RFC complex from the hyperthermophilic archaea of the…
Cajanus cajan Linn. is commonly used in Indian folk medicine to treat various ulcers and inflammatory conditions. Different extracts of the leaves was prepared with petroleum ether, ethyl acetate, ethanol and water. Each type of Extract of the leaves of Cajanus cajan Linn. was investigated for possible anti gastric ul…
Within a microscopic model and a Green's function technique we have calculated the temperature, size and magnetic field dependence of the phonon energy and damping of the mode, as well as the real and imaginary part of the dielectric function, and , respectively, in double perovskite La2 NiMnO6 thin films. All these q…
THz emission from semiconductor surfaces is influenced by the sign and strength of the surface field as well as the relaxation dynamics of the photoinduced carriers. In this paper, an experimental study on argon implanted silicon surfaces is presented. Moderately doped silicon wafers were implanted with 100 keV argon…
The Devanathan-Stachurski electrochemical cell for measurement of hydrogen-permeation into a steel sheet was extended to an electrolyte-flowing design. Increase in flow rate of the entry cell induces increase in hydrogen-evolution current at the entry electrode but decrease in hydrogen-permeation current at the hydrog…
Cochlear implants restore the inner ear hearing using electrical stimulation of the auditory nerve. However, there is potential to improve the implant's function in terms of stimulation selectivity by increasing the number of electrode contacts. Meanwhile, the electrode stiffness shall not be elevated, because this wo…
Molecular dynamics (MD) simulation is commonly used in the study of protein dynamics, and in recent years, the extension of MD simulation to the study of metalloproteins is gaining much interest. Choice of force field is crucial in MD studies, and the inclusion of metal centers complicates the process of accurately de…
