The work was aimed at investigation of metal oxide thick film sensitive electrodes being attractive materials for the next generation of low cost wireless pH sensors. In this study, thick film potentiometric and conductimetric RuO2 based pH sensors were fabricated by screen printing method. This method allows preparat…
Anodic alumina with surface of hexagonal patterned nanodots was prepared by a two-step anodizing procedure. Scanning electron microscope and atomic force microscopy results clearly showed the formation of self-organized hexagonal patterned nanostructure. Diameters of the nanodots were controlled by choosing different…
Phase transition and band structure of Cu 2 O are systematically investigated by using the HSE06 range-separated hybrid functional. Cubic Cu 2 O under pressure transforms to the metastable hexagonal phase. Our further investigations reveal that the first-order phase transition is driven by the elastic and dynamical in…
Scatter correction is an essential data correction in quantitative PET imaging. In this work, a prototype of single scatter simulation using fast Monte-Carlo method (MC-SSS) for scatter estimate scaling instead of tail fitting was evaluated concurrently with the existing single-scatter simulation (SSS) algorithm. Reco…
Wide bandgap Al x Ga 1−x N (x = 0.7−1) p–n junction is realized on a silicon substrate through polarization induced doping. Polarization induced positive charge field is produced by linearly grading from AlN to Al 0.7 Ga 0.3 N, and negative charge field is generated by an inverted grading from Al 0.7 Ga 0.3 N to AlN.…
Titanium and titanium alloys, based on their excellent physicochemical properties and superior biocompatibility, appear to be suitable for medical devices. In addition to the original titanium properties, many functional enhancement such as shape-memory function, low elastic modulus, super-hydrophilic and antibacteria…
It is found that the core-shell structured grains are easy to produce for fine grain doped BaTiO 3 ceramics in the sintering process. We study the influence of the core-shell structure on the Curie—Weiss temperature and dielectric properties of BaTiO 3 ceramics by using effective medium approximation (EMA). Considerin…
ZnO nanorod was prepared by microwave assisted method. The crystal structure of the nano powders were confirmed by X-Ray diffraction analysis and the mean particle size was estimated by the Scherrer , s formula .The surface morphology of the nano particles were analyzed by using SEM . The absorption spectrum of the ma…
A red light-emitting phosphor of SrMoO4: Pr3+was synthesized by a convenient high-temperature solid-state reaction method. The structures, morphologies and optical properties of as-prepared products were characterized by X-ray diffraction (XRD), transmission electron microscope (FESEM) and photoluminescent (PL). A str…
Synthesis of volatile Eu(acac)3phen and Tb(acac)3phen complexes by solution technique were reported in this paper. The combination of Eu and Tb complexes, namely TbxEu(1-x)(acac)3phen (x=0.1,0.3,0.5,0.7,0.9) were also synthesized by maintaining stoichiometric ratio. Optical properties of these synthesized complexes we…
Clutch is a mechanical device, which is used to engage or disengage the source of power from the rest of the power transmission system at the operator’s will. The clutch can connect or disconnect the driving shaft from the driven shaft when necessary. Clutches are designed to transfer maximum torque with minimum heat…
Gumfoot threads attached to the substrate may allow spiders to retain prey. These threads were recently discovered in adult females of Pholcidae spiders, and are similar to those in Theridiidae. We report for the first time the presence of gumfoot threads in the webs of immature spiders (fifth instar juveniles) of the…
Novel silver/silver chloride (Ag/AgCl) nanocomposite materials were produced by forming plasmonic photocatalyst Ag/AgCl nanoparticles in the porous support materials of polymers such as nylon 6,6 and polyurethane. This was achieved by way of a simple aqueous synthesis method, followed by a light-induced chemical reduc…
Sewage sludge can be a source of micronutrients, such as zinc (Zn) and nickel (Ni), for Cerrado soils; however, since they are heavy metals, continuous use of this residue requires an evaluation of the dynamics of these elements in the soil/plant system. This study aimed to evaluate the dynamics of Zn and Ni in a soil…
Summary Amorphous degradable copolymer networks such as poly[(L‐lactide)‐co‐glycolide] (PLGA) are promising multifunctional polymers with tailorable degradation profiles and capable of a thermally‐induced shape‐memory effect. Currently, the shape‐memory performance for covalently crosslinked networks based on linear P…
In the present study, two possible mechanisms of protein folding are analized. One of them is based on the hypothesis that at the first step of protein folding a nucleus is formed and then the remaining part of the molecule or domain is folded around it. For example, β-proteins containing 3β-corners can fold in this w…
Negative corona onset characteristics of the stranded conductors based on the ultra-high voltage (UHV) corona cage were studied in the paper. Based on the corona self-sustaining criterion in extreme uneven electric fields and the secondary emission process of the photoelectrons, the corona onset calculation model in t…
The yield of radioisotopes formed during photonuclear reactions in a natural mixture of titanium isotopes is measured at an electron energy of ≈15 MeV using a slot microtrone.
The as-cast structure of grate bar used in sintering trolley is primarily comprised of austenite and eutectic (eutectic austenite and eutectic carbide). The austenite is dendrite, while the carbide is reticular and chrysanthemum-like. The grate bars were quenched and tempered under various temperature (one set of samp…
The optical, and electrophysical characteristics of hydrogenated silicon oxycarbonitride films synthesized by the plasma enhanced chemical vapor decomposition of the mixtures of 1,1,1,3,3,3-hexamethyldisilazane with oxygen and nitrogen in the temperature range of 373–973 K have been studied. It has been shown that the…
