AbstractAbstract
[en] A simple method for determining gallium with Rhodamine B, by the modification of the method proposed by Onishi and Sandell. The complex (RH) GaCl4 is extracted with a mixture benzene-ethylacetate (3:1 V/V), from an aqueous medium 6 M in hydrochloric acid. The interference of foreign ions is studied. (C.G.C.)

Apresenta-se um metodo mais simples para a dosagem de galio com Rodamina B, atraves da modificacao do metodo proposto por Onishi e Sandell. O complexo (RH) GaCl4 e extraido com uma mistura benzeno-acetato de etila (3:1 V/V), de meio aquoso 6 M em acido cloridrico. Promove-se a analise deste metal em diversos materiais, mostrando a viabilidade do metodo. Estuda-se tambem a interferencia de ions estranhos. (C.G.C.)Original Title

AbstractAbstract
[en] In this work, we report catalytic degradation of rhodamine B (Rh B) using sodium borohydride (NaBH4) in the presence of ZnCo2O4 nanodice as a catalyst. ZnCo2O4 catalysts were synthesized using a microwave irradiation method with an optimized temperature of 180 °C for different reaction times of 30 and 60 min and were named ZCo-30 and ZCo-60. HR-TEM and XRD results revealed that the synthesized ZnCo2O4 nanodice were cubic. Rh B dye degradation activity ∼95% was achieved within 25 min when 60 μl of a 2 mg ml−1 ZCo-30 dispersion was used.

AbstractAbstract
[en] A new rhodamine-based sensor 1 was designed and synthesized by incorporating rhodamine B and benzimidazole moieties. Sensor 1 exhibits high selectivity and sensitivity to Cu"2"+ in CH_3CN-water solution (HEPES buffer, pH = 7.0) with an obvious color change from colorless to pink. Other metal ions such as Hg"2"+, Ag"+, Pb"2"+, Sr"2"+, Ba"2"+, Cd"2"+, Ni"2"+, Co"2"+, Fe"2"+, Mn"2"+, Cu"2"+, Zn"2"+, Ce"3"+, Mg"2"+, K"+ and Na"+ had no such color change and have no significant influence on Cu"2"+ recognition process. The interaction of Cu"2"+ and sensor 1 was proven to adopt a 1:1 binding stoichiometry and the recognition process is reversible

AbstractAbstract
[en] A known Hg2+ selective rhodamine B derivatised probe 1 was reinvestigated as a colorimetric and fluorescent probe for Cu2+ through changing the applied solvent media. Probe 1 exhibited good selectivity and sensitivity to Cu2+ in CH3CN-H2O (7:3, v/v, HEPES 10 mM, pH 7.0) solution with a detection limit of 9.74 Χ 10-7 M. The Cu2+ sensing event was proved to be irreversible through hydrolysis of 1 to release rhodamine B

AbstractAbstract
[en] Rhodamine 6G as a guest was introduced in a host cholesteric binary compensated mixture cholesteryl chloride + cholesteryl laurate 74:26% mols % in the ratios 1:200, 1:100, 1:50 moles guest : host. A more pronounced variation colour effect was observed at the mixture containing 1:100 mols rhodamine, by following the cholesteric-nematic phase transform under the influence of an applied electric field. The dependence of this electro-optical color effect on the temperature and on the d.c. electric field was studied. (author)

AbstractAbstract
[en] We have observed the fluorescence emission of a monolayer of Rhodamine 6G coated on the surface of 32 μm glass microsphere under 632.8 nm excitation. The structural resonances of upconversion fluorescence around 550-580 nm region were observed, which could be assigned by using the well-known Lorenz-Mie Formalism

AbstractAbstract
[en] We show how a half-adder logic circuit can be implemented on one molecule for a molecule exhibiting both S1→S0 and S2→S0 fluorescence. This is achieved by using both one photon S0→S1 excitation and consecutive S1→S2 excitation and establishing logic thresholds by utilizing the laser-induced photoquenching process. We present results pertaining to rhodamine and azulene molecules, in which, for the first time, an all optical half-adder logic circuit is implemented.
