NLRP3: a key regulator of skin wound healing and macrophage-fibroblast interactions in mice.

Wound healing is a highly coordinated process driven by intricate molecular signaling and dynamic interactions between diverse cell types. Nod-like receptor pyrin domain-containing protein 3 (NLRP3) has been implicated in the regulation of inflammation and tissue repair; however, its specific role in skin wound healing remains unclear. This study highlights the pivotal role of NLRP3 in effective skin wound healing, as demonstrated by delayed wound closure and altered cellular and molecular responses in NLRP3-deficient (NLRP3) mice.

A new in situ fracturing-enhanced oxidative remediation for various low-permeability phenanthrene-contaminated soils: Oxidation effectiveness and kinetics of potassium permanganate.

A new in situ fracturing-enhanced oxidative remediation approach was recommended in this study to achieve rapid and efficient remediation of low-permeability contaminated sites. The objective of this study was to evaluate the effects of permeability and potassium permanganate (KMnO) concentration on the oxidation effectiveness and kinetics of KMnO in phenanthrene (PHE)-contaminated soil through rigid-wall hydraulic conductivity tests and a series of laboratory experiments. The results indicate that for various low-permeability contaminated soils, there was a critical KMnO concentration to significantly reduce the remediation time and a critical Darcy velocity to meet remediation goals.

Competitive Effect of Surface Hydrophobicity-Hydrophilicity and the Number of Accessible Protons on Water-Assisted Proton Conductivity in Metal-Organic Frameworks: Dielectric σ-Relaxation Triggered by Disordered Guest Ionic Migration and Its Mechanism.

The rapid upsurge of metal-organic frameworks (MOFs) has sparked profound interest in their potential as proton conductors for proton exchange membrane fuel cells. However, proton-conducting behaviors of hydrophobic MOFs remain poorly understood compared with their hydrophilic counterparts, largely due to the absence of a microscopic phase separation structure akin to that found in Nafion membranes. Herein, we demonstrate a strategy for regulating the structures and proton conductivities of MOFs by separately incorporating hydrophobic -C(CF)- group alongside hydrophilic -O- and -SO- groups into organic ligands as linkers.

Oxygen Evolution Reaction of Amorphous/Crystalline Composites of NiFe(OH)/NiFeO.

Orbital structures are strongly correlated with catalytic performance, whereas their regulation strategy is still in pursuit. Herein, the Fe 3 and O 2 orbital hybridization was optimized by controlling the content of amorphous NiFe(OH) (a-NiFe(OH)), which was grown in situ on crystalline NiFeO (c-NiFeO) using an ultrasonic reduction method. The results of electron energy loss spectroscopy (EELS) and X-ray absorption spectra (XAS) revealed that the Fe-O orbital hybridization in a-NiFe(OH) is effectively strengthened by jointing with the adjacent oxygen (O) in c-NiFeO, which is further confirmed by the higher antibonding orbital energies based on density functional theory (DFT) calculations.

Bleaching effect of radiation-induced darkening in Yb-doped large mode area photonic crystal fiber based on deuterium and hydrogen loading.

We report the radiation-induced darkening (RD) effect caused by X-ray radiation and the bleaching effect caused by D/H/N loading in self-developed Yb-doped large mode-area photonic crystal fibers (LMA PCFs). The decrease in the slope efficiency caused by irradiation decays exponentially with an increase in the X-ray radiation doses, and the radiation-induced gain variation (RIGV) showed a linear decay trend with increasing irradiation doses. The slope efficiency of Yb-doped LMA PCF, which significantly degraded from 71.
