Enhancing the Performance of Hole-Conductor-Free Printable Mesoscopic Perovskite Solar Cells through Polyaniline-Mediated Iodine Recycling and Defect Passivation.

Printable mesoscopic perovskite solar cells (p-MPSCs) provide an opportunity for low-cost manufacturing of photovoltaics. However, the performance of p-MPSCs is severely compromised by iodine defects. This study presents a strategy by incorporating polyaniline (PANI) to achieve both iodine recycling and iodine defect passivation to significantly improve the performance of p-MPSCs.

Opportunities and challenges of bacterial extracellular vesicles in regenerative medicine.

Extracellular vesicles (EVs) are membrane-bound vesicles that are shed or secreted from the cell membrane and enveloped by a lipid bilayer. They possess stability, low immunogenicity, and non-cytotoxicity, exhibiting extensive prospects in regenerative medicine (RM). However, natural EVs pose challenges, such as insufficient targeting capabilities, potential biosafety concerns, and limited acquisition pathways.

Polyphenol oxidase mediated (-)-epigallocatechin gallate stabilized protein in body wall of Apostichopus japonicus: Characteristics and structure.

Heat treatment is the most common processing method in Apostichopus japonicus (A. japonicus) processing. However, improper heat treatment can lead to the degradation of protein.

Spontaneous bifacial capping of perovskite film for efficient and mechanically stable flexible solar cell.

Flexible perovskite solar cells (F-PSCs) are appealing for their flexibility and high power-to-weight ratios. However, the fragile grain boundaries (GBs) in perovskite films can lead to stress and strain cracks under bending conditions, limiting the performance and stability of F-PSCs. Herein, we show that the perovskite film can facilely achieve in situ bifacial capping via introducing 4-(methoxy)benzylamine hydrobromide (MeOBABr) as the precursor additive.

Low background catalytic redox recycling coupled with hybridization chain reaction amplification for highly sensitive electrochemical aptamer luteinizing hormone assay.

The concentration variation of luteinizing hormone (LH) regulates the cell cycle of oocyte meiosis and significantly affect the whole reproductive cycle. Sensitively quantifying the LH biomarker therefore plays an important role for reproductive disease diagnosis. By coupling a new low background catalytic redox recycling strategy with hybridization chain reaction (HCR), we propose a highly sensitive bio-electrochemical aptamer LH sensing method.
