Summary: Orthogonal Cu3SnS4 (CTS) nano-crystals were synthesized, with Cu7S4 seeds forming first at 130 degrees C and orthorhombic CTS nano-crystals forming at 180 degrees C. Selenization at 500 degrees C for 20 minutes resulted in the formation of CTSXSe4-X, which showed good conductivity and electrocatalytic activity for I-3(-) reduction when used as counter electrodes in dye-sensitized solar cells. The optimal 1.7 μm thick CTSXSe4-X counter electrode achieved a power conversion efficiency of 7.57%.

Summary: Fiber solar cells, woven into textiles, have shown potential in supplying electricity for wearables. However, achieving high power conversion efficiencies in real-world applications remains a challenge. A unique hybrid counter electrode was designed using metal current collector fiber, aligned carbon nanotube sheet, and porous titanium dioxide/poly(vinylidene fluoride-co-hexafluoropropylene) film. This design achieved a record power conversion efficiency of 12.52% and maintained efficiency below 10% after bending, twisting, or pressing for 1000 cycles. The integration of these fiber dye-sensitized solar cells with fiber batteries demonstrated an effective power solution for wearables.

Summary: This study explores manganese dioxide (MnO2) and copper-doped manganese dioxide (Cu-MnO2) nanoparticles as candidates for the counter electrode (CE) material in dye-sensitized solar cells (DSSCs), aiming to provide low-cost alternatives to platinum (Pt). Experimental results show that DSSC devices fabricated with 10 wt% Cu-MnO(2) as CE exhibit better performance. The low-cost feature of using Cu-MnO(2) as CE is encouraging for further research in improving the efficiency of DSSCs with alternative CEs.

Summary: Third-generation solar cells, such as dye-sensitized solar cells and quantum dot-sensitized solar cells, require counter electrodes (CEs) for their functionality. Platinum-based CEs are dominant but expensive, thus alternative materials like transition metal chalcogenides (TMCs) and transition metal dichalcogenides (TMDs) have been explored. This study provides a comprehensive review of the major components and working principles of these solar cells, and evaluates the performance efficiencies resulting from TMS-based CEs compared to Pt-based CEs.

Summary: The study showed that utilizing CZTS as the counter electrode resulted in a power conversion efficiency (PCE) of 4.3% for TiO2-based photoanodes. The highest PCE achieved was 6.5% for BaSnO3-based photoanodes, presenting a promising alternative oxide to TiO2 photoanodes. This work suggests that the newly developed BSO-CZTS DSSCs could be a competitive alternative to TiO2-Pt DSSCs.

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.
