In the text, a new fluorescent probe based on rhodamine spirolactam ring was designed and synthesized. Rhodamine-like derivatives have not only good response speed luminous performance, but also special switch type structure, which can specifically recognize responsive metal ions. paper, Rh-TEF, 6G derivative of rhodamine, synthesized by condensation reaction, successfully used for solutions sa...

The fabrication of metal oxide nanofibers using (titanium (IV) isopropoxide) and (tin tert-butoxide) weight ratio 1:1 precursor in presence poly (vinyl pyrrolidone) as a binder well-known electrospinning technique is reported. average diameter TiO2, SnO2, composite TiO2-SnO2 were found to be the range 75–110 nm. characterized thermogravimetric analysis (TGA) understand polymer evaporation tempe...

tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. photo degradation of congo red (azo dye) showed that photo catalytic property of the as-prepared wo3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. photo degradation of rhodamine b (cationic triary...

graphene, a new member of the carbon family, was used as an adsorbent due to its exceptional capability to remove rhodamine b (rb) and malachite green (mg), two organic dyes, from aqueous solutions. adsorption kinetics of rb and mg onto graphene and adsorption capacity of the adsorbent were studied. also the effects of parameters, including ph, contact time, temperature, and adsorbent dosage we...

The study was conducted at the University of Nebraska Pesticide Application and Technology Laboratory in North Platte, July 2015. Two application volume rates (100 200 l · ha−) three nozzle types (XR, AIXR, TTI) were selected two flow (0.8 1.6 min−) a single speed 7.7 km h−. Each collector type [Mylar washed (MW), Mylar image analysis (MIA), water-sensitive paper (WSP), Kromekote (KK)] arranged...

Rhodamine 123 is a lipophilic cationic compound that is selectively taken up by cancer cell mitochondria. This compound is toxic to epithelial cancer cells in vitro and displays significant anticancer activity in vivo. However, the mechanism of action of rhodamine 123 in intact, actively metabolizing cell preparations is unknown. We have used 31P- and 13C-nuclear magnetic resonance spectroscopy...

Oxidative stress plays an important role in the pathogenesis of heart disease. Tocotrienol-rich fraction (TRF) is antioxidant and that has potential to reduce risk This study determine protective effects palm TRF against H2O2-induced oxidative damage neonatal rat cardiomyocytes (NRCM). The NRCM were divided into control, treated with (10 µg/mL), H2O2 (0.5 mM) prior induction (pre-treatment). Ce...

We report a substitution of 9-phenylanthracenyl group into rhodamine derivatives that can induce the J-aggregate formation of rhodamine moieties in the aqueous solution upon the addition of a halide ion. From X-ray crystallographic analysis, the dramatic red-shift in the absorption band (i.e. app. 100 nm) originates from the cooperative slipped-stacking of rhodamine and anthracene molecules.

and a cytoplasmic carboxy terminus of ~35 kDa (C2) (FIGURE 1B). The catalytic domain of adenylyl cyclases is hypothesized to be bipartite and split between C1 and C2 regions. The predicted size of mammalian adenylyl cyclases ranges from 110 to 130 kDa, but these proteins generally have an apparent molecular weight on SDS gels of ~200 kDa due to glycosylation in the extracellular loops of M1 and...
