Various types of fluorescent carbon nanoparticles, often called dots (CDs), are synthesized by different polycondensation methods: microwave irradiation, hydrothermal conditions or solution chemistry at ambient temperature with subsequent chemical functionalization. The CDs deposited on TiO2 films to be probed as electron transport layers in perovskite photovoltaics and the anode for photoelect...

Complex electrolyte diffusion through the stacked graphene nanosheets limits their electrochemical performance. As a potential solution, this study explored of nitrogen-doped quantum dots (NGQDs) to induce 3D porous orientation holey oxide (hGO) nanosheets. The sizes NGQDs and antisolvent for phase separation assisted assembly were optimized achieve nanoporous network. This nano-network serves ...

background: lateral ridge split technique is a way to solve the problem of the width in narrow ridges with adequate height. simultaneous insertion of dental implants will considerably reduce the edentulism time. materials and methods: twenty-five patients who were managed with ridge splitting technique were enrolled. thirty-eight locations in both jaws with near equal distribution in quadrants ...

The electron paramagnetic resonance of copper (II)-tetram m ine nitrate in solution of methanol and water has been investigated. The data obtained from the spectra at room tem perature and 97 °K together with the optical transition energies determined from single crystal polarized absorption spectra at 77 °K by other authors were used to calculate the LCAO-MO bonding parameters. The bonding orb...

We present the universal two-loop splitting functions that describe the limits of two-loop n-point amplitudes of massless particles when two of the momenta are collinear. To derive the splitting amplitudes, we take the collinear limits of explicit two-loop four-point helicity amplitudes computed in the ’t Hooft-Veltman scheme. The g → gg splitting amplitude has recently been computed using the ...

This study is about the non-uniform electric field for splitting of water in oil emulsion. If the process occurs in an inhomogeneous electrical field, the drops are polarized and then their mobility is increased. The emulsion drops will be charged and move toward the central point of splitter where the maximum intensity of electrical field has been concentrated. In this process, the drops encou...

Titania nanotubes (TNT) prepared by anodization of Ti foils were used for water splitting in a standalone cell. The concentration polarization between the anode side (1M NaOH) and cathode side (0.5 M H2SO4) ensured that the water splitting reaction could take place with no external bias and separate H2 and O2 evolution could be achieved. The destructi...

The effect of three salicylic acid (0, 50 and 100 mg l-1) and K2SO4 (0, 0.1 and 0.2 %) levels on some characteristics nut and physiological parameters of pistachio trees cv. ‘Owhadi’ were investigated. Treatments were applied at endospermic growth stage of seed and cotyledons appearance. The results showed that potassium increase yield, splitting percentage; nut fresh mass and kernel dry mass a...

The cooling characteristics of liquid nitrogen can effectively weaken the mechanical properties dry hot rock reservoirs, improve porosity and permeability rock, thus development utilization geothermal resources. In order to explore weakening effect on high-temperature reservoir rocks, uniaxial compression tests, Brazil splitting three-point bending tests were conducted granite, synchronous acou...
