One Step

TiO2/g-C3N4 (GNT) fibers with 1%, 2.5% and 5% (wt%) ratios have been synthesized via one-step electrospinning using polyvinylpyrrolidone (PVP) polymer. Results showed mesoporous fibrous catalysts consisted of anatase (80.0–85.1%) and rutile phase (14.9–20.0%), with diameter between 200–300 nm and band gap lower than 3.0 eV confirming the absorption shift to visible-light region. The formation of •OH radicals and methylene blue dye degradation increases as the g-C3N4 doping percent also increases, following the trend ΤiO2 < GNT1% ≈ GNT2.5% < GNT5%. A z-scheme mechanism is attributed to the photocatalytic performance confirming the potential for green chemistry and environmental technology applications.

Diagnostic Work Up

Quality assurance and inclusion of prospective evaluation of costs of treatment in phase 3 and 4 pharmaceutical trials are becoming increasingly important. Not only high technology applications have to be investigated, but also relatively cheap but very common strategies for diagnostic work up and therapy. This may yield major savings. We are at the beginning of an era in which waste of resources may be reduced by scientific analysis with improvement in patient care and teaching achieved as a result.
