We evaluated the systemic hemodynamic effects induced by nociceptin (NC) and NC-related peptides, including the NC receptor antagonist [Phe1psi(CH2-NH)Gly2]NC(1-13)NH2 ([F/G]NC(1-13)NH2) in unanesthetized normotensive Swiss Morini mice. Bolus intravenous injection of NC decreased mean blood pressure and heart rate. The hypotensive response to 10 nmol/kg NC lasted <10 minutes, whereas a more pro...

Recent studies have demonstrated that ammonia is an emerging energy vector for the distribution of hydrogen from stranded sources. However, there are still many unknown parameters need to be understood before can a substantial substitute in fuelling current power generation systems. Therefore, attempts mainly utilised as natural gas (mainly composed methane) mitigate carbon footprint latter. Co...

Primary and secondary reactions involved in the thermal decomposition of NH2OH are studied with a combination of shock tube experiments and transition state theory based theoretical kinetics. This coupled theory and experiment study demonstrates the utility of NH2OH as a high temperature source of OH radicals. The reflected shock technique is employed in the determination of OH radical time pro...

We present a novel strategy for mapping the localization of guest molecules (GMs) in mesoporous materials by combining mechanochemistry with solid-state nuclear magnetic resonance (ssNMR) spectroscopy. To this end, we consider model guest–host systems benzoic acid (BA) and para-fluorobenzoic (4-FBA) embedded MCM-41 material examine recently proposed loading (MeLo) procedure efficient encapsulat...

To apply mobile crystalline material 41 (MCM-41), which has a larger specific surface area than many other nanoporous silicas, for energy absorption, chlorotrimethylsilane treatment is performed to adjust the structure of inner surfaces of nanopores. As the treatment time is sufficiently long, the pore surface can be changed from hydrophilic to hydrophobic, leading to an energy absorption effic...

This investigation examines metal ion adsorption on mesoporous silicate, MCM-41, synthesized from sodium silicate solution and cethyltrimethylammonium bromide (CTAB). MCM-41 has potential as an adsorbent material, with a regular hexagonal pore structure, large specific surface area, and large pore volume. The MCM-41 synthesized for this investigation is characterized using powder X-ray Received...

The direct and indirect methods in solvent media and grinding method in a solvent-free media were used to prepare the MCM-41/ZnO and MCM-48/ZnO photocatalysts. The X-ray diffraction (XRD) patterns showed that zinc oxide nanoparticles were put into MCM-41 and MCM-48 substrates and there were ZnO crystallites as secondary phase in the extra framework of mesoporous materials. The decrease of surfa...
