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, ¹H NMR and ¹³C 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 10³, 2.4 x 10³ and 0.2 x 10³M^-1, 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>_max 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^-1 for <b>UA1</b>, <b>UA6</b> and <b>UA7</b>, respectively

Electrochemical Characteristics and Li⁺ Ion Intercalation Kinetics of Dual-Phase Li₄Ti₅O₁₂/Li₂TiO₃ Composite in the Voltage Range 0–3 V

Li₄Ti₅O₁₂, Li₂TiO₃, and dual-phase Li₄Ti₅O₁₂/Li₂TiO₃ composite were prepared by sol–gel method with average particle size of 1, 0.3, and 0.4 μm, respectively. Though Li₂TiO₃ is electrochemically inactive, the rate capability of Li₄Ti₅O₁₂/Li₂TiO₃ is comparable to that of Li₄Ti₅O₁₂ at different current rates. Li₄Ti₅O₁₂/Li₂TiO₃ also shows a good rate performance of 90 mA h g^–1 at a high rate of 10 C in the voltage range 1–3 V, attributable to increased interfaces in the composite. While Li₄Ti₅O₁₂ delivers a capacity retention of 88.6% at 0.2 C over 50 cycles, Li₄Ti₅O₁₂/Li₂TiO₃ exhibits no capacity fading at 0.2 C (40 cycles) and a capacity retention of 98.45% at 0.5 C (50 cycles). This highly stable cycling performance is attributed to the contribution of Li₂TiO₃ in preventing the undesirable reaction of Li₄Ti₅O₁₂ with the electrolyte during cycling. Cyclic voltammetric curves of Li₄Ti₅O₁₂/Li₂TiO₃ in the 0–3 V range exhibit two anodic peaks at 1.51 and 0.7–0.0 V, indicating two modes of lithium intercalation into the lattice sites of active material. Owing to enhanced intercalation/deintercalation kinetics in 0–3 V, the composite electrode delivers a superior rate performance of 203 mAh/g at 2.85 C and 140 mAh/g at 5.7 C with good reversible capacity retention over 100 cycles
