In this investigation, Eu3+ doped YVO4 /YBO3 phosphors were synthesized individually by conventional solid state method at 1100 °C under atmosphere condition. Meanwhile, different amounts of LiClwere used as the flux compound to modify the morphology of the phosphor particles and also final luminescence properties. It was concluded that even small amounts of fluxes play a vital role in the grow...

Background: New treatment modalities are developed with the aim of escalating tumor absorbed dose and simultaneously sparing the normal structures. The use of nanotechnology in cancer treatment offers some possibilities including destroying cancer tumors with minimal damage to healthy tissues. Zinc Oxide nanoparticles (ZnO NPs) are wide band gap semiconductors and seem to have a good effect on ...

We report 17O dynamic nuclear polarisation (DNP) enhanced solid-state NMR experiments at 18.8 T. Several formulations were investigated on the Mg(OH)2 compound. A signal enhancement factor of 17 could be obtained when the solid particles were incorporated into a glassy o-terphenyl matrix doped with BDPA using the Overhauser polarisation transfer scheme whilst the cross effect mechanism enabled ...

In order to describe the fusion of two very heavy nuclei at near barrier energies, a generalized Langevin approach is proposed, which incorporates the quantum statistical fluctuations in accordance with the fluctuation and dissipation theorem. It is illustrated that the quantum statistical effects introduce an enhancement of the formation of compound nucleus, though the quantum enhancement is s...

Calphostin C, a protein kinase C inhibitor, reduced phorbol ester-induced enhancement of catecholamine secretion but not primary Ca"-induced secretion from digitonin-permeabilized bovine adrenal medullary cells, indicating that this compound selectively inhibited protein kinase C-dependent

In Korean information retrieval, term mismatches between indexing terms and query terms are a serious obstacle to the enhancement of retrieval performace. Term matches are not produced because of a space usage of compound nouns and also various representations of a phrase. This paper presents an extended model of Korean information retrieval of alleviating these term mismatches between indexing...

Thermoelectric figure-of-merits (ZT) are enhanced or degraded by crystal defects such as twins and excess atoms that are correlated with thermal conductivity (k) and carrier concentration (n). For Bi2Te3, it is unclear whether the crystal defects can enhance ZT without a degradation in the thermopower factor. In the present study, n-type Bi2Te3 nanowires (NWs) are electrochemically synthesized ...

Exposure to amphetamine (AMPH) in vivo produces an enduring enhancement ('sensitization') in AMPH-stimulated striatal DA release in vitro. Experiments were conducted to determine whether striatal DA release evoked by neuronal depolarization is altered by AMPH pretreatment in a similar manner. It was found that AMPH pretreatment produced a long-lasting (at least one week) enhancement in striatal...
