Das Einzige, das Bestand hat, ist die Veränderung. Dieser Prozess war noch nie so schnell wie jetzt. Unsere Welt verändert sich im Minutentakt und macht es uns immer schwerer, einen Anker für unser Leben zu setzen. Darum umso wichtiger, den aktuellen Herausforderungen stellen, Lösungsansätze suchen in eigene Tun implementieren. Mit Techniken der Wo-bist-du-Frage oder Auseinandersetzung m...

We describe two methodologies for dissolving ionic/polar species in scCO 2 . Both lead to a broadening of the range of applications for scCO 2 . Fluorinated surfactants may be used to prepare water in carbon dioxide microemulsions to allow solubilization of ionic and biological species. We outline also the preparation of scCO 2 soluble metal precursors that can be impregnated efficiently into p...

BACKGROUND AND THE PURPOSE OF THE STUDY Microemulsions are thermodynamically stable, clear dispersions of water, oil, surfactant, and cosurfactant. This study was aimed to develop flurbiprofen microemulsion for enhanced transdermal delivery and investigate the effects of different surfactants and cosurfactants on its delivery and phase behavior. METHOD Various surfactant-cosurfactant mixtures...

HE locus of Woolly is in chromosome 2 of the tomato, Lycopersicon escuZentum, in which the basic chromosome number is 12. Three alleles, in addition to the normal non-Woolly allele, WO+, are known. WO and Wov are dominant and lethal when homozygous, and WO"' is partially dominant and viable when homozygous (RICK and BUTLER 1956). Woolly plants have thicker, longer trichomes than the normal and ...

Phage-mediated horizontal gene transfer (HGT) is common in free-living bacteria, and many transferred genes can play a significant role in their new bacterial hosts. However, there are few reports concerning phage-mediated HGT in endosymbionts (obligate intracellular bacteria within animal or plant hosts), such as Wolbachia. The Wolbachia-infecting temperate phage WO can actively shift among Wo...

A W-containing inorganic-organic nanohybrid with a plate-like morphology has been successfully prepared through a nonaqueous synthetic route using WCl(6) as the tungsten source and benzyl alcohol as the solvent. The as-prepared hybrid nanomaterial was used directly as an efficient precursor for the formation of WO(3) nanoplates via a simple thermal treatment process. The as-obtained WO(3) mater...

the aim of this study was to develop a microemulsion system as a medium for laccase-catalyzed reactions. phase behavior studies were conducted by constructing partial pseudo-ternary phase diagrams for systems comprising of cetyltrimethylammonium bromide (ctab), various organic solvents as the oil phase (i.e., hexane, cyclohexane, heptane, octane, isooctane, toluene, isopropyl myristate), two co...

where WO and k are constants. WO represents the theoretical maximum work and would be attained only if the contraction could take place infinitely slowly. k represents the theoretical minimum time and would be attained only if no external work were done. From experiments on isolated frog's muscle a relation has been found between the theoretical maximum work WO, the energy H liberated in an iso...

Epitaxially grown, 2.4-microm-thin layers of KY(WO(4))(2):Gd(3+), Lu(3+), Yb(3+), which exhibit a high refractive index contrast with respect to the undoped KY(WO(4))(2) substrate, have been microstructured by Ar beam milling, providing 1.4-microm-deep ridge channel waveguides of 2 to 7 microm width, and overgrown by an undoped KY(WO(4))(2) layer. Channel waveguide laser operation was achieved ...
