Experimental Investigation on the Effectiveness of 1‑Butyl-3-methylimidazolium Perchlorate Ionic Liquid as a Reducing Agent for Heavy Oil Upgrading
An ionic liquid (IL), 1-butyl-3-methylimidazolium
perchlorate, [BMIM]Â[ClO<sub>4</sub>], is synthesized and used as a
reducing agent to upgrade a selected heavy oil. The effects of [BMIM]Â[ClO<sub>4</sub>] on viscosity, density, SARA contents, elemental compositions,
and molecular weight of the heavy oil are studied. The results show
that the heavy oil treated with [BMIM]Â[ClO<sub>4</sub>] has reduction
in viscosity and density. The results also indicate that the presence
of [BMIM]Â[ClO<sub>4</sub>] significantly changes the composition of
the heavy oil. Moreover, the effects of [BMIM]Â[ClO<sub>4</sub>] on
the interfacial tension (IFT) of oil–water and oil recovery
are tested. Results shows that [BMIM]Â[ClO<sub>4</sub>] can improve
the mobility of heavy oil by reducing the IFT of oil–water
and increase the recovery factor by 79.94%

Ataf Ali - Excell Data from Synthesis and characterization of azo-guanidine based alcoholic media naked eye DNA sensor
DNA sensing always has an open meadow of curiosity for biotechnologists and other researchers. Recently, in this field, we have introduced an emerging class of molecules containing azo and guanidine functionalities. In this study, we have synthesized three new compounds (<b>UA1</b>, <b>UA6</b> and <b>UA7</b>) for potential application in DNA sensing in alcoholic medium. The synthesized materials were characterized by elemental analysis, FTIR, UV-visible, <sup>1</sup>H NMR and <sup>13</sup>C NMR spectroscopies. Their DNA sensing potential were investigated by UV-visible spectroscopy. The insight of interaction with DNA was further investigated by electrochemical (cyclic voltammetry) and hydrodynamic (viscosity) studies. The results showed that compounds have moderate DNA binding properties, with the binding constants range being 7.2 x 10<sup>3</sup>, 2.4 x 10<sup>3</sup> and 0.2 x 10<sup>3</sup>M<sup>-1</sup>, for <b>UA1</b>, <b>UA6</b> and <b>UA7</b>, respectively. Upon binding with DNA, there was a change in colour (a blue shift in the <i>λ</i><sub>max</sub> value) which was observable with a naked eye. These results indicated the potential of synthesized compounds as DNA sensors with detection limit 1.8, 5.8 and 4.0ng µl<sup>-1</sup> for <b>UA1</b>, <b>UA6</b> and <b>UA7</b>, respectively
