This paper reports on durable and nearly temperature-independent (at 298-328 K) T-type photochromism of colloidal Cu-doped ZnS nanocrystals (NCs). The color NC powder changes from pale yellow to dark gray by UV light irradiation, the back a time scale several tens seconds minutes after stopping while decoloration reaction is accelerated submillisecond in solutions. much faster than those conven...

Wastewater containing azo dye has become a main harm in water pollution. Therefore, development of environment friendly materials with efficient purifying capacity seized more and attention people devoting to wastewater processing. On the other hand, advancement metallic glasses degrading organic contaminant also received wide concern. Cu-based amorphous alloy excellent corrosion resistance goo...

BACKGROUND The latissimus dorsi (LD) muscle flap has been widely used in facial reanimation surgery. However, there are no standards to what degree the muscle flap may be safely thinned because the three-dimensional positional relationship of thoracodorsal artery, vein, and nerve inside the LD muscle is poorly understood. METHODS From 18 formalin-fixed cadavers, we made 36 transparent specime...

The simple, low molecular weight, azodye acid yellow 9 (AY9) is electrochemically treated in a suitable electrolytic cell using NaCl as a supporting electrolyte, carbon fleece as cathode and platinated titanium as anode. Samples from certain time periods of treatment are analysed. HPLC-UV chromatograms demonstrate the degradation of the initial azodye, while diode array detector (DAD) spectra g...

This study reports a new white-rot fungus Cerrena sp. WR1, identified based on an 18S rDNA sequence, which can secrete extracellular forms of laccase with a maximal activity reaching 202 000 U l⁻¹ in a 5-l fermenter. A laccase protein, designated Lcc3, was purified and shown to be N-linked glycosylated by PNGase F and liquid chromatography tandem mass spectrometry analyses. The respective full-...

Flow injection analysis (FIA) methods for the spectrophotometric determination of CO2 and SO2 in wines are described. The determination of CO2 is based on the colour change of a low capacity buffer (containing an acid-base indicator) due to the dissolved carbon dioxide. The determination of SO2 is based on the decoloration of malachite green by sulphur dioxide. Two FIA manifolds are presented; ...

The rapid development of computer graphics and imaging provides the modern archeologist with several tools to realistically model and visualize archeological sites in 3D. This, however, creates a tension between veridical and realistic modeling. Visually compelling models may lead people to falsely believe that there exists very precise knowledge about the past appearance of a site. In order to...
