Summary: The study investigated the binding of oxazine and thiazine dyes with CTAB and Tween 80 surfactants in alkaline medium. Dyes showed blue shifting in lambda(max) value in presence of both CTAB and Tween 80, with higher absorbance in CTAB. MB, TBO, and AA dyes displayed higher stability with CTAB/Tween 80 compared to AB, AC, and NB.

Summary: This study investigated the impact of adding beta-carotene on the structure and properties of fresh O/W emulsions with different oil phases and emulsifiers. The results showed that beta-carotene interacted with the ingredients of the emulsions, influencing their behavior in the gastrointestinal tract and the stability/bioaccessibility of beta-carotene. Different oil phases and emulsifiers exhibited varied effects on the emulsion properties, with beta-carotene playing a role in changes to surface tension and viscoelasticity.

Summary: The integration of energy harvesting and storage functions into a single device is a frontier research orientation in the field of photocapacitors. However, the complexity and mismatch between the different units in the integrated device result in significant energy loss. In this study, a voltage adjustable hybrid supercapacitor (VAHSC) is designed as an energy storage unit to effectively harmonize the energy harvest and storage units. The optimal photocapacitor achieves high storage efficiency and excellent charge/discharge cycle stability, marking a substantial step towards practical applications of solar-charging energy storage integrated devices.

Summary: In this study, non-ionic surfactant Tween 20 was added into the MAPbI(3) perovskite layer, and a high-quality perovskite film was fabricated using the thermal-assisted blade-coating method. Tween 20 effectively passivated defects and traps in the perovskite films, resulting in higher photoluminescence intensity and longer carrier lifetime. At the optimal concentration of 1.0 mM, the performance of the perovskite solar cell was significantly enhanced, with a champion power conversion efficiency of 18.80%.

Summary: Calcium looping (CaL) process offers a possible solution for next generation Concentrated Solar Power (CSP) plants. However, the conventional CaL-CSP system has limited solar absorption capability due to the white nature of CaCO3. This study introduces dark Ca2MnO4 derived from natural manganocalcite to enhance solar absorption and anti-sintering ability of CaO. The presence of Ca2MnO4 stabilizes the materials' energy storage density and ensures high and stable energy storage performance over prolonged operation cycles.

Summary: Four different boron and cerium doped TiO2 photocatalysts were synthesized by the EDTA-citrate method and studied for degradation of two common fluoroquinolone-based antibiotics under sunlight. The synthesized catalysts showed 90-93% degradation for both antibiotics and demonstrated stability up to three consecutive runs, with e- and OH identified as the dominant species responsible for the photocatalytic activity. These catalysts also showed efficient disinfection capabilities against E.coli under solar light.
