A Negishi coupling based synthesis of 1,2,4,5-tetra(9-anthryl)benzene derivatives, possessing X-shaped molecular structures, is described. The results X-ray crystallographic analysis show that two-dimensional highly ordered packing structure the crystalline state unsubstituted derivative a consequence intermolecular π-π and CH-π interactions between anthracene units. Photoirradiation as precipi...

The handling, dispersion, manipulation, and functionalization of carbon nanotubes and nanopipes often require the use of solvents. Therefore, a good understanding of the wetting properties of the carbon nanotubes is needed. Such knowledge is also essential for the design of nanotube-based nanofluidic devices, which hold the promise of revolutionizing chemical analysis, separation, drug delivery...

Cage-like and core-shell metallo-borospherenes exhibit interesting structures bonding. Based on extensive global searches first-principles theory calculations, we predict herein the perfect tetrahedral cage-like Td La4B24 (1) La4B29 (2), La4B29+ (3), La4B29− (4) which all possess same geometrical symmetry as their carbon fullerene counterpart C28, with four equivalent interconnected B6 triangle...

Recently, the concern about energy efficiency in wireless communications has been growing rapidly. Manufacturers and researchers have developed innovative solutions, highlighting the benefits in reducing operational expenditures (OPEX) and carbon footprint. Professional Mobile Radio (PMR) systems, like Terrestrial Trunked Radio (TETRA), have been designed to provide voice and data services to p...

In this work, the steady state S0-S1 and S0-S2 absorption and emission behaviour of the water-soluble tetrakis(N-methyl-4-pyridyl)porphyrin zinc(ii) tetrachloride (ZnTMPyP) in media of constant and high ionic strength, both with and without iodide ions as a fluorescence quencher, was measured. The quenching of the ZnTMPyP S1 state by iodide ions proceeds primarily through diffusion-limited inte...

In this study, the kinetics of gas hydrate formation in the presence of tetra-n-butyl ammonium fluoride (TBAF) and cetyl trimethyl ammonium bromide surface active ingredient (CTAB) with zinc nano oxide (ZnO) are investigated and the most important kinetic parameters of hydrate formation such as their induction time and storage capacity were measured. The kinetic experiments were carried out in ...

Comparatively little is known about host-defense activities in the fish heart. Investigations showed that intraperitoneally injected carbon particles are actively taken up by the cardiac endothelial cells of the medaka Oryzias latipes, but less so by those of the goldfish Carassius auratus and lemon tetra Hyphessobrycon pulchripinnis. (In vitro experiments confirmed these species differences in...
