Summary: Conductive polymer blend gel electrolytes improve the stability of dyesensitized solar cells by reducing leakage and enhancing electrode adhesion. In this study, polyvinylpyrrolidone (PVP) and polyaniline (PANI) blends were synthesized through in-situ polymerization and characterized using various methods. The optimal composition of the electrolyte solution was selected, and the conductivity was found to be influenced by salt concentration. Solid-state dye-sensitized solar cells with gel electrolytes exhibited better long-term stability compared to conventional cells.

Summary: This study investigates the use of diatom frustules incorporated into multilayer photoelectrodes to enhance the efficiency of dye-sensitized solar cells. It is found that the efficiency of cells with a diatom frustule composite layer is increased by 101% compared to the control cells. The enhanced efficiency is attributed to improved light absorption and dye adsorption facilitated by the scattering and trapping effects of diatom frustules.

Summary: In this study, three organic fluorine-containing dyes were designed and synthesized, and it was found that the introduction of fluorine can significantly broaden the absorption spectra of the dyes, but does not improve the light-harvesting capability of solar cells. One of the dyes, with fluorine substitution at the 3-position, showed a relatively high open-circuit photovoltage compared to the fluorine-free dye, and when co-sensitized with other dyes, it achieved a remarkably high power conversion efficiency and long-term stability. This work suggests that judicious molecular engineering and co-sensitization are promising strategies for highly efficient and stable solar cells.

Summary: Nanostructured thin films synthesized by a green aqueous sol-gel route using anatase TiO2 nanoparticles show promising optoelectronic properties for the fabrication of optically active electrodes. These electrodes exhibit a spongy-like nanostructure with preserved nanoparticles size, resulting in a huge surface area, and demonstrate significant contributions from both intercalation capacitance and pseudocapacitance to the total stored charge. Fast and reversible coloration with high optical modulation and coloration efficiency makes the sol-gel derived titania thin films potential candidates for multifunctional 'smart windows'.

Summary: Femtosecond transient absorption spectroscopy (FTAS) is used to study the physics of halide perovskites at different dimensions, morphologies, and architectures, providing insights into their electronic and excitonic optical transitions. In this study, FTAS is conducted on monolayer and multilayer quasi-2D perovskites in the Ruddlesden-Popper phase, using dodecylammonium (DA) and methylammonium (MA) as spacers and organic cations. The measurements reveal different absorption bleaching energies, which are compared with theoretical simulations and assigned to exciton transitions with principal quantum numbers 1s and 2s. The analysis also shows that exciton-exciton annihilation is the main relaxation mechanism in the first picoseconds, while exciton radiative recombination occurs at longer time delays.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
