This study presents the fabrication of a low cost poly-acrylic acid (PAA) based emission filter integrated with a low light CMOS contact imager for fluorescence detection. The process involves the use of PAA as an adhesive for the emission filter. The poly-acrylic solution was chosen due its optical transparent properties, adhesive properties, miscibility with polar protic solvents and most imp...

In this research work, a novel strategy for the heterogenization of sultone based acidic ionic liquids via their non-covalent immobilization on nano silica sulfuric acid is reported and catalytic ability prepared heterogeneous catalysts synthesis tetrazolopyrimidines derivatives investigated. The physicochemical properties were studied using thermal spectroscopic techniques such as 1H 13C NMR, ...

The gas-phase structure of the conjugate base of p-hydroxybenzoic acid (and related compounds) and the influence of the solvent used in its generation by electrospray ionization have recently been under debate. While the phenoxide structure is known to be lower in energy in the gas phase, the carboxylate structure is favored in aqueous solution, fuelling the controversy. Here we probe the struc...

Activity coefficients at infinite dilution of some common solvents in a protic ionic liquid ethylammonium nitrate have been measured using well established gas-chromatography-method. This method was possible to apply due to extremely low vapour pressure of ethylammonium nitrate at temperatures below 100 °C. Activity coefficients and separation factors were compared with those for aprotic ionic ...

Bis(diphenylthiophosphoryl)amine, a weak protic acid, can be readily deprotonated. The alkali salts [Ph2P(S)]2NM have been used to prepare S-bonded complexes with transition metals containing a NP2S2M six membered ring [1]. Although the struc­ tures of the neutral ligand [Ph2P(S)]2NH [2] and of several transition metal complexes [1] have been de­ termined by X-ray diffraction techniques, struct...

Esterification reactions of some polyols and diols were investigated in the presence of SnO2 and nano-SnO2 and the results were compared with the catalyst-free conditions. High conversions were obtained for most of the reactions in the presence of SnO2 and nano-SnO2 which shows the high catalytic activity of SnO2 and nano-SnO2</sub...

detritylation of 5'-dimethoxytrityl nucleosides have been quantitatively achieved in minutes at room temperature under aprotic neutral conditions by using stannous chloride. of additional practical consideration and in contrast to protic acids, no depurination was observed with this reagent.

From the time immemorial, sodium borohydride has been used for the reagent of choice for reducing various carbonyl compounds and acid chlorides in protic solvents. Over the past decades the utility of sodium borohydride has been greatly expanded and various modifications have been developed. Reductive dechlorination of aromatic halo nitro compounds have a great significance in the field of orga...
