a simple, highly sensitive, accurate and selective method was presented for determination of trace amounts of cu (ii) in water samples. the stability of an n, n´ -disalicylideneethylenediamine modified nano geraphene especially in concentrated hydrochloric acid was studied which used as a recycling and pre-concentration reagent for further uses of n, n´-disalicylideneethylenediamine modified na...

In this paper, a porous polymer nanostructure has been integrated with droplet-based microfluidics in a single planar format. Monolithic porous polymer (MPP) was formed selectively within a microfluidic channel. The resulting analyte bands were sequentially comartmentalised into droplets. This device reduces band broadening and the effects of post-column dead volume by the combination of the tw...

A simple and rapid Nano LC method has been developed for the screening of arginase inhibitors. The is based on immobilization biotinylated a neutravidin functionalized nano HPLC capillary column. step performed by frontal analysis very fast only takes few minutes. miniaturized column 170 nL (length 5 cm, internal diameter 75 ?m) significantly decreased required amount used enzyme (25 pmol). Thi...

The challenging task in our ecosystem is to reduce acidic gas emissions some extent. Many gases are emitted from the industries like H2S, CO, CO2, SO2, NO, and NO2 as exhaust gases. Among these gases, NO2, SO2 acidic, which results adverse effects on humans, animals, plants. increase emission of CO2 both anthropogenic industrial sources resulted mitigation studies. absorption studies were carri...

In this study, we aimed to figure out how the depolymerization of polyethylene terephthalate produces monomers, dimers, trimers, and other oligomers bis (2-hydroxyethyl) terephthalate. Polymerization was achieved in a bubble column reactor with 0.05 wt% 40–50 nm magnesium oxide nanoparticle as catalyst. A used perform recycling process at boiling point ethylene glycol atmospheric pressure. Depo...

This paper deals with the study of Nanotechnology experimentation in Civil Engineering which includes the development, advantages and limitations of Nano concreting technologies. For reducing carbon emission during cement manufacturing fly ash is used as a replacement in ordinary Portland cement which is termed as Portland pozzolana cement(PPC), this inclusion relatively increases the workabili...

We report a new and simple design of a fully automated dual-online ultra-high pressure liquid chromatography system. The system employs only two nano-volume switching valves (a two-position four port valve and a two-position ten port valve) that direct solvent flows from two binary nano-pumps for parallel operation of two analytical columns and two solid phase extraction (SPE) columns. Despite ...
