A two-step junction welding technique for achieving high-performance broadband silver nanowire transparent conductive films.

Transparent conductive films (TCFs) are critical components of various optoelectronic and photovoltaic devices. The performance of TCFs is mainly ascribed to their superior transparency and low sheet resistance. However, the welding strategy for silver nanowires (AgNWs), the primary material used in TCFs, can significantly affect the optical and electrical properties of the films.

Identification of immune-associated genes for the diagnosis of ulcerative colitis-associated carcinogenesis via integrated bioinformatics analysis.

Background: UC patients suffer more from colorectal cancer (CRC) than the general population, which increases with disease duration. Early colonoscopy is difficult because ulcerative colitis-associated colorectal cancer (UCAC) lesions are flat and multifocal. Our study aimed to identify promising UCAC biomarkers that are complementary endoscopy strategies in the early stages.

Endocannabinoid interference blocks post-global cerebral ischemia depression through prefrontal cortico-amygdala projections.

Up to 45% of patients surviving from transient global cerebral ischemia (GCI) after cardiac arrest develop post-global cerebral ischemia depression (PGCID), but how to treat PGCID is clinically unknown. Here we find that cannabinoid type-1 receptor (CBR) antagonists, CBR knockout and endocannabinoid (eCB) synthesis inhibition block acute stress-induced PGCID. Application of acute stress to GCI mice increases CBR activity from ventromedial prefrontal cortical (vmPFC) terminals synapsing with the basolateral amygdala (BLA) neurons, indicating the involvement of increased vmPFC-BLA synaptic eCB signaling in PGCID induction.

Proton-capture strategy for stable redox potential in luteolin detection using SnO-ZIF-67 electrodes.

Variations in H⁺ concentration significantly impact the redox potential of luteolin during electrochemical sensor detection, leading to indeterminate electrochemical signals and hindering accurate identification of luteolin. In this study, we developed a proton-capture strategy for electrochemical sensing by synthesizing a ZIF-67-modified SnO (SnO-ZIF-67) composite, enabling constant peak potential detection across a range of pH environments. We demonstrated through both experimental methods and density functional theory (DFT) that ZIF-67 induces a high density of oxygen vacancies within the SnO₂ crystal, which capture protons dissociated from luteolin, thereby preventing potential shifts during electrochemical detection.

The preparation of CuM/SiO (M = Bi, Mg, Mn) catalysts applied in ethynylation of formaldehyde for 1,4-butynediol synthesis: the positive interface effect of CuO and BiO.

The ethynylation of formaldehyde catalyzed by Cu-based catalysts is an important synthesis method for 1,4-butynediol relating to high-value-added chemicals. In this work, a series of CuM/SiO (M = Bi, Mg, Mn) catalysts were prepared by a deposition-precipitation method and applied in the ethynylation reaction. The effects of different promoters (Bi, Mg, Mn) on the catalytic activity were investigated.

Enriched environment may improve secondary brain injury after traumatic brain injury by regulating the TLR2/NF-κB signaling pathway.

Background: Traumatic brain injury (TBI) can cause damage to the blood-brain barrier, resulting in neuroinflammatory reactions and brain edema that seriously affect the recovery of neurological function. We hypothesize that an enriched environment (EE) regulates the TLR2/NF-κB signaling pathway and thereby modulates the integrity of the blood-brain barrier to achieve neuroprotective effects.

Objective: This study evaluated the expression of toll-like receptor (TLR)-2 after TBI in a rat model, with the aim of determining whether TLR2/NF-κB improves secondary brain injury by inhibiting the release of inflammatory factors and reducing brain edema.

Antitumor Cream: Transdermal Hydrogel Containing Liposome-Encapsulated Ruthenium Complex for Infrared-Controlled Multimodal Synergistic Therapy.

A transdermal drug delivery cream, which is non-invasive and painless, containing a liposome-encapsulated Ru(II) complex (LipoRu) is created for the treatment of skin cancer. This formulation capitalizes on the synergistic antitumor effects of two-photon excited photodynamic therapy (PDT), photothermal therapy (PTT), and chemotherapy. LipoRu exhibits effective tumor accumulation, efficient cellular uptake, pH-sensitive and infrared-accelerated release, and dual localization to the nucleus and mitochondria.

Numerical simulation of fracture patterns in roof strata with different thicknesses.

Roof breaking is the root cause of rock burst and mine earthquake. However, the classical "thin plate theory" and "thick plate theory" cannot fully reveal the mechanical mechanism of the influence of roof thickness-span ratio on the fracture mode. In this paper, based on the cohesive element technology, the mechanical behavior of cohesive element failure was studied according to the maximum nominal stress criterion and BK fracture criterion, and the fracture mechanical behavior of roofs with different thicknesses fixed on four sides under uniform load was numerically simulated.

Fluorescent robust photoactuator via photo-crosslinking induced single-layered janus polyimide.

Advanced smart polymer materials with the ability of reversible deformation under external stimuli hold great potential in robotics, soft machines, and flexible electronics. However, the complexity and low efficiency for fabricating actuators along with their limited functionality hinder further progress. Here an efficient and mild catalyst-free thiol-yne click polymerization was developed to fabricate photosensitive polyimide (PI) films.

A high entropy metallic-high entropy nonmetallic community as a high performance electrocatalyst for the oxygen evolution reaction and oxygen reduction reaction.

The multi-element synergism in high-entropy materials (HEMs) provides great opportunities as multi-functional catalysts or for the promotion of tandem reactions. Herein, a strategy that utilizes a high entropy precursor is proposed to realize the formation of a unique high entropy metallic-high entropy non-metallic community (HEM-HENMC). Aminotriazole acts as a "bonding agent" for the high entropy precursor, and not only binds the five metals Cr, Mn, Fe, Co and Ni together, but also introduces nitrogen and carbon .

Size effect of accelerated seismic release from failures under compression in naturally fractured media.

It is crucial to understand the scaling behaviors of acoustic emissions (AEs) preceding damage localization in order to predict failures of brittle solids under compression. Yet, the effect of length scale on the complex interplay between the initiation, propagation, and coalescence of pre-existing fracture networks and corresponding AE behaviors is poorly understood. In this study, we perform laboratory compressional experiments on naturally fractured rocks at four sample sizes from 50 to 300 mm whose strength generally exhibits a finite-size effect.
