Negatively charged 1-butyl-4-methyl-pyridiniumtetrafluroborate (BMPTB) ionic liquid was electrochemically deposited on the surface of carbon paste electrode (CPE) by cyclic voltammetric (CV) technique in 0.1 M nitric acid. It exhibited an electrocatalytic activity towards the oxidation of DA, AA, and UA in 0.1 M phosphate buffer solution (pH 6.6). The effect of concentration, scan rate, and pH was studied for dopamine. The BMPTB/CPE showed an excellent electrocatalytic activity for selective detection of DA in the presence of AA and UA by using CV and differential pulse voltammetry (DPV) respectively. Detection limit of dopamine was found to be 1 x 10(-8) M. The present technique provides a novel method for the simultaneous determination of DA, M and UA in their mixture sample.

A Selective Electrochemical Sensing of Serotonin and Epinephrine at Glassy Carbon Electrode Modulated with Brilliant Green: A Voltammetric Study

Rukaya Banu, B. E. Kumara Swamy, Anup Pandith

Summary: In this study, an electrochemical sensing method based on the electropolymerization modulation of brilliant green on a glassy carbon electrode was introduced for rapid and sensitive identification of serotonin (SE) and epinephrine (EP) using cyclic and differential pulse voltammetric procedures. The pH of the supporting solution was maintained between 6.2-8.0. The electrode showed a proportional relationship between current intensities and analyte concentrations, with a low detection limit (0.74x10(-6) M for SE and 0.58x10(-6) M for EP). The modulated sensor demonstrated superior electrocatalytic characteristics for simultaneous quantification of SE and EP in a sample mixture.

Dimer-parity dependent odd-even effects in photoinduced transitions to cholesteric and twist grain boundary SmC* mesophases: PBG characteristics

Rajalaxmi Sahoo, C. Reshma, D. S. Shankar Rao, C. V. Yelamaggad, S. Krishna Prasad

Summary: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

Vaporization enthalpy of azeotropes by the solution calorimetry method

Artem A. Petrov, Ekaterina A. Titova, Aydar A. Akhmadiyarov, Ilnaz T. Rakipov, Boris N. Solomonov

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Surface adsorption of adenine on pristine and B/N/O/P-doped coronene as a biosensing substrate for DNA detection- DFT study

R. Aneesh Kumar, S. Jamelah Al-Otaibi, Y. Sheena Mary, Y. Shyma Mary, Nivedita Acharjee, Renjith Thomas, Renjith Raveendran Pillai, T. L. Leena

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Unveiling regularities of B12N12-X nanocages as a drug delivery vehicle for the nitrosourea: The influence of periods and groups

Yan Zhang, Yafei Luo, Lingkai Tang, Mingyan E, Jianping Hu

Summary: This study investigates the effects of different transition metal decorations on B12N12 nanocages on the adsorption properties of nitrosourea drugs using computational methods. The results reveal the presence of weak non-covalent interactions between metals and nanocages, and the interaction between drugs and nanocages plays a significant role in drug adsorption. Compared to free drugs, the adsorption of drugs on nanocages can facilitate electron transfer, reduce energy gaps and chemical hardness, indicating activity at the target site.

Aromatic aldehyde oxidation by hexacyanoferrate(III) catalyzed by Ru(VI) in alkaline medium

C. I. Alcolado, J. Poblete, L. Garcia-Rio, E. Jimenez, F. J. Poblete

Summary: In this study, the selective oxidation of aromatic aldehydes was investigated using Ru(VI) as a catalyst and hexacyanoferrate (III) as a cooxidant in an alkaline medium. The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

Effective removal of hypnotic drug from the aqueous medium through adsorption on graphene oxide magnetic derivatives

Inez A. Barbieri, Marcos L. S. Oliveira, Franciele S. Bruckmann, Theodoro R. Salles, Leonardo Zancanaro, Luis F. O. Silva, Guilherme L. Dotto, Eder C. Lima, Mu. Naushad, Cristiano R. Bohn Rhoden

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

A sensitivity analysis on thermal conductivity of Al2O3-H2O nanofluid: A case based on molecular dynamics and support vector regression method

Hongyan Huang, Chunquan Li, Siyuan Huang, Yuling Shang

Summary: This study examines the sensitivity of the thermal conductivity of water-based alumina nanofluids to changes in concentration, sphericity, and temperature. The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.

Valentyn Rudenko, Anatolii Tolochko, Svitlana Bugaychuk, Dmytro Zhulai, Gertruda Klimusheva, Galina Yaremchuk, Tatyana Mirnaya, Yuriy Garbovskiy

Summary: This paper reports on the synthesis, structural characterization, spectral and nonlinear-optical properties of glass nanocomposites made of glass forming ionic liquid crystals and nanoparticles. The study reveals that by exciting the nanocomposites within their absorption band, a control over effective optical nonlinearities can be achieved, allowing the modification of the magnitude and sign of the effective nonlinear absorption coefficient. The proposed strategy using metal-alkanoates based glass-forming ionic liquid crystals and nanoparticles shows great potential for the development of nanophotonics and plasmonics technologies.
