Ce(3+)-doped yttrium aluminum garnet (YAG:Ce) nanocrystals were successfully synthesized via a facile sol-gel method. Multiple characterization techniques were employed to study the structure, morphology, composition and photoluminescence properties of YAG:Ce nanophosphors. The YAG:Ce0.0055 sintered at 1030 °C exhibited a typical 5d(1)-4f(1) emission band with the maximum peak located at 525 nm...

eybees from the bud or bark of certain coniferous trees, has long been used in folk medicine. Several studies on the isolated chemical components of propolis have reported a number of biological responses including antibacterial, anti-fungal, anti-inflammatory and anti-tumor activities. In particular, 3,4-dihydroxycinnamic acid phenetyl ester (CAPE) displays various potent anti-tumor effects. C...

We report the comparative investigation of fabricating type-II waveguide lasers in Nd:Y3Al5O12 (Nd:YAG) using femtosecond laser pulses at 515 and 1030 nm. focus on comparison track morphologies, modification thresholds, overall efficiency ultrafast inscription (ULI) process creating these waveguides. For both wavelengths, we demonstrated low propagation losses 0.2 dB/cm. achieved lowest reporte...

The pressure dependence of the relative photolysis rate of HCHO vs. HCDO has been investigated for the first time, using a photochemical reactor at the University of Copenhagen. The dissociation of HCHO vs. HCDO using a UVA lamp was measured at total bath gas pressures of 50, 200, 400, 600 and 1030 mbar. The products of formaldehyde photodissociation are either H2 + CO (molecular channel) or HC...
