Evaluation of the Correlation between Gut Microbiota and Renal Function in Chronic Kidney Disease Patients.

Chronic kidney disease (CKD) has recently emerged as a significant, global public health threat, and the gut microbiota are now recognized as playing a crucial role in the pathogenesis and progression of CKD. In this study, we investigated the correlation between differential gut microbiota and renal function impairment by analyzing the structure, diversity, and other characteristics of the gut microbiota in patients with CKD. Our findings indicated that CKD patients exhibit decreased species diversity and evenness in their gut microbiota compared to healthy individuals, with notable differences in community composition between the groups.

Peanuts are highly nutritious but pose a significant risk of triggering food allergies. While heat treatment can reduce the allergenicity of many foods, it may also alter their structure, potentially impacting detection results.

A ferroelectrically modulated ultrasensitive two-dimensional perovskite phototransistor with zero-gate-bias.

Two-dimensional (2D) organic-inorganic halide perovskites are promising sensitive materials for optoelectronic applications due to their strong light-matter interactions, layered structure, long carrier lifetime and diffusion length. However, a high gate bias is indispensable for perovskite-based phototransistors to optimize detection performances, since ion migration seriously screens the gate electric field and the deposition process introduces intrinsic defects, which induces severe leakages and large power dissipation. In this work, an ultrasensitive phototransistor based on the (PEA)SnI perovskite and the Al:HfO ferroelectric layer is meticulously studied, working without an external gate voltage.

The third strategy: modulating emission colors of organic light-emitting diodes with UV light during the device fabrication process.

The modulation of emission color is one of the most critical topics in the research field of organic light-emitting diodes (OLEDs). Currently, only two ways are commonly used to tune the emission colors of OLEDs: one is to painstakingly synthesize different emitters with diverse molecular structures, the other is to precisely control the degree of aggregation or doping concentration of one emitter. To develop a simpler and less costly method, herein we demonstrate a new strategy in which the emission colors of OLEDs can be continuously changed with UV light during the device fabrication process.

Partial Ligand Stripping from CsPbBr Nanocrystals Improves Their Performance in Light-Emitting Diodes.

Halide perovskite nanocrystals (NCs), specifically CsPbBr, have attracted considerable interest due to their remarkable optical properties for optoelectronic devices. To achieve high-efficiency light-emitting diodes (LEDs) based on CsPbBr nanocrystals (NCs), it is crucial to optimize both their photoluminescence quantum yield (PLQY) and carrier transport properties when they are deposited to form films on substrates. While the exchange of native ligands with didodecyl dimethylammonium bromide (DDAB) ligand pairs has been successful in boosting their PLQY, dense DDAB coverage on the surface of NCs should impede carrier transport and limit device efficiency.

Stepwise-Process-Controlled Ligand Management Strategy for Efficient and Stable Perovskite Quantum Dot Solar Cells.

CsPbI perovskite quantum dots (QDs) have attracted much attention in the field of solar cells because of their excellent photovoltaic properties. Conventional modification of long-chain insulating ligands can ensure good dispersion and film-forming stability of QDs, but the limitations of their low defect passivation ability and poor charge transport ability will make them fail to achieve high efficiency in the corresponding solar cell devices. In this study, by introducing "Benzylphosphonic acid" short-chain ligands to the surface of CsPbI QDs, the ligands were re-administered on the surface during the preparation of the CsPbI QDs as well as during the film-forming process.
