Ligand‐Mediated Shape Engineering of SWIR InAs Colloidal Quantum Dots for Photodetector Applications

Advanced Materials, EarlyView.
The table of contents: A robust ligand‐engineering strategy is introduced for SWIR InAs CQDs synthesized from amino‐arsine precursors. Bulky OA ligands induce controlled shape evolution, allowing access to >1700 nm absorption under mild conditions. Halide‐based inkification enables photodetectors with 19.1% EQE at 1300 nm and detectivity exceeding 1010

Dynamic Mechanical Loading Modulates Extracellular Vesicle Production and Cargo in Meniscus Fibrochondrocytes

Advanced Materials Interfaces, EarlyView.
Dynamic mechanical loading of outer meniscus fibrochondrocytes increases extracellular vesicle (EV) yield and alters EV composition. When applied to progenitor cells, these mechanically primed EVs modulate the expression of matrix‐related genes.

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

Hepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

Design of sigma-delta modulator 10-16 bits for resolver digital converter

Dianzi Jishu Yingyong, 2022
In this paper, a sigma-delta modulator for 10-16 bit resolver digital converter is designed. The modulator is a second-order structure. On this basis, a chopper modulator circuit is added to eliminate the flicker noise.

Linking Device Performance to Nanoscale Photoactivation of Grain Boundaries in 2D Hybrid Halide Perovskites

Advanced Materials Technologies, EarlyView.
The opto‐electronic response of polycrystalline (PEA)2PbBr4 thin films is investigated by correlating macroscopic photodetector performance with nanoscale mapping techniques. Grain boundary density is systematically tuned through crystallization control and linked to device responsivity.

Malectin Alleviates Endoplasmic Reticulum Stress in Gestational Diabetes Mellitus via Glycoprotein Quality Control Mechanisms

Advanced Science, EarlyView.
Malectin alleviates high glucose‐induced ER stress and damage in placental trophoblasts, a function dependent on its six critical carbohydrate‐binding residues. In a GDM mouse model, administration of TAT‐Malectin ameliorated hyperglycemia and placental ER stress and prevented fetal macrosomia.
