Summary: Productive electron transfer between dye and redox shuttle is crucial for high-performing dye-sensitized solar cells. This study demonstrates that noncovalent self-assembly of dye and redox shuttle via g-stacking interactions can increase the electron transfer rate. The use of a dye with pyrene-based donor group and a redox shuttle with pyrene substitution leads to enhanced dye regeneration and reduced recombination rate. A power conversion efficiency of 22.8% is achieved under fluorescent lighting conditions.

Summary: Increasing the electron transfer rate between the dye and redox shuttle by noncovalent self-assembly through pi-stacking interactions has been shown to enhance the performance of dye-sensitized solar cells. This study synthesized a dye with a pyrene-based donor group and tested it with two terpyridine-based redox shuttles. The results demonstrated that the presence of pyrene groups on both the dye and redox shuttle increased the rate of dye regeneration and resulted in a significantly higher power conversion efficiency under fluorescent lighting conditions.

Summary: Solar cells are a promising source of energy conversion. However, the traditional use of Pt as a counter electrode (CE) in solar cells is expensive, scarce, and corrosive. To address this issue, a novel quaternary nanocomposite of rGO/MnO2/NiO/CuO (RMNCu) was employed as the CE in DSSCs with different photoanodes. The DSSCs with RMNCu as the CE exhibited a power conversion efficiency (PCE) of 93.31% compared to Pt-CE in the same conditions, making RMNCu a promising candidate for DSSC counter electrodes.

Summary: Dye-sensitized solar cells (DSSCs) are cheaper and easier to produce than silicon-based solar cells. Carbon materials can be used as counter electrodes in DSSCs instead of platinum electrodes due to their catalytic characteristics and affordability. Copper (I) thiocyanate (CuSCN) has recently been considered a promising hole transport material for advanced solar cells. In this study, dye-sensitized solar cells were fabricated using carbon-graphite counter electrodes with solid-state CuSCN. The use of carbon-based composite with CuSCN counter electrode showed improved efficiency and stability, with a maximum conversion efficiency of 8.56% achieved under AM 1.5 solar conditions.

Summary: Non-monotonic electrical resistance changes have been observed in multi-walled carbon nanotube (MWNT)/epoxy nanocomposites under tensile loading, but the mechanism is not fully understood. This study evaluates the impact of curing condition on the piezoresistivity of MWNT/epoxy nanocomposites, and suggests that a higher curing temperature can enhance the monotony of the piezoresistivity. The results indicate that the molecular structure of the polymer matrix contributes to the non-monotonic piezoresistivity of CNT/epoxy nanocomposites.

Summary: We introduced Ni Apt as the first aptamer with a characterized dissociation constant for recognizing Ni-NTA. It displays a remarkable binding affinity towards Ni-NTA (Kd = 106 nM). Additionally, it can be eluted from the resin using imidazole or EDTA, similar to the removal of His-tag from Ni-NTA resin. The versatile capabilities of Ni Apt make it a valuable molecular tool in nucleic acid purification and recognition applications.
