Multiscale Modeling of Heat Conduction in a Hydroxyethyl Cellulose/Boron Nitride Composite Realizing Ultrahigh Thermal Conductivity via a "Moisture-Activated" Strategy.

Polymer-based thermally conductive composites are widely used in microelectronics for heat dissipation and packaging, for which the filler arrangement and the filler/matrix interfacial thermal resistance (ITR) are key factors limiting superior thermal conduction realization. This work reveals the effects of filler modification and orientation on thermal duction in the boron nitride (BN)/hydroxyethyl cellulose (HEC) through multiscale simulation approaches. Nonequilibrium molecular dynamics (NEMD) identifies that the thermal conductivity of the BN molecule is not size-dependent and proves that thermal resistance is dramatically reduced after hydroxylation modification (BN).

Novel Spectrophotometric Method for Robust Detection of Trace Copper and Cobalt in High-Concentration Zinc Solution.

In the purification process of zinc hydrometallurgy, the spectra of copper and cobalt seriously overlap in the whole band and are interfered with by the spectra of zinc and nickel, which seriously affects the detection results of copper and cobalt in zinc solutions. Aiming to address the problems of low resolution, serious overlap, and narrow characteristic wavelengths, a novel spectrophotometric method for the robust detection of trace copper and cobalt is proposed. First, the Haar, Db4, Coif3, and Sym3 wavelets are used to carry out the second-order continuous wavelet transform on the spectral signals of copper and cobalt, which improves the resolution of copper and cobalt and eliminates the background interference caused by matrix zinc signals and reagents.

CeCl-Catalyzed C-H Alkylation of -Sulfonyl Ketimines with Alkanes and Ether via Photoinduced Ligand-to-Metal Charge Transfer.

A cerium-catalyzed C-H alkylation of -sulfonyl ketimines with low-cost and readily available alkanes as alkyl sources was developed. This transformation proceeded through the synergy of photoinitiated ligand-to-metal charge transfer (LMCT) using a chlorine radical as an HAT reagent and air as a green oxidant. A series of alkylated -sulfonyl ketimines were synthesized with moderate to good yields in a highly atom-economic manner under chemical oxidant-free conditions.

The overall structures were confirmed via X-ray crystallography, revealing the horizontal expansion of the biicosahedral AuAg yielding [AuAg(CHNOS)(DPPB)] and vertical expansion of the biicosahedral AuAg yielding [AuAg(CHNS)(DPPM)].

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.

Semaglutide promotes the transition of microglia from M1 to M2 type to reduce brain inflammation in APP/PS1/tau mice.

A growing number of studies show that the diabetes drug Semaglutide is neuroprotective in Alzheimer's disease (AD) animal models, but its mode of action is not fully understood. In order to explore the mechanism of Semaglutide, 7-month-old APP/PS1/tau transgenic (3xTg) mice and wild-type (WT) mice were randomly divided into four groups: control group (WT + PBS), AD model group (3xTg + PBS), Semaglutide control group (WT + Semaglutide) and Semaglutide treatment group (3xTg + Semaglutide). Semaglutide (25 nmol/kg) or PBS was administered intraperitoneally once every two days for 30 days, followed by behavioral and molecular experiments.

Traditional Chinese medicine FYTF-919 (Zhongfeng Xingnao oral prescription) for the treatment of acute intracerebral haemorrhage: a multicentre, randomised, placebo-controlled, double-blind, clinical trial.

Background: There are few proven treatments for acute spontaneous intracerebral haemorrhage, and they all target reducing expansion of the haematoma. The traditional Chinese medicine FYTF-919 (Zhongfeng Xingnao) in an oral solution is comprised of several Chinese herbs that are widely used to treat patients with intracerebral haemorrhage in China on the understanding that they enhance resorption of the haematoma and reduce neuroinflammation. We aimed to provide a reliable assessment of the safety and efficacy of FYTF-919 in patients with moderate to severe acute intracerebral haemorrhage.

The heterojunction exhibited excellent photoelectric conversion efficiency, which was nearly 2.5-fold and 5.

GBMPhos: A Gating Mechanism and Bi-GRU-Based Method for Identifying Phosphorylation Sites of SARS-CoV-2 Infection.

Phosphorylation, a reversible and widespread post-translational modification of proteins, is essential for numerous cellular processes. However, due to technical limitations, large-scale detection of phosphorylation sites, especially those infected by SARS-CoV-2, remains a challenging task. To address this gap, we propose a method called GBMPhos, a novel method that combines convolutional neural networks (CNNs) for extracting local features, gating mechanisms to selectively focus on relevant information, and a bi-directional gated recurrent unit (Bi-GRU) to capture long-range dependencies within protein sequences.

Why does distilled liquor (Baijiu) have a yellowish color: A comprehensive analysis.

Elucidating the mechanisms underlying Baijiu production is a shared aspiration among academic groups specializing in the field of Baijiu research. This study comprehensively examined the mechanisms underlying the yellowish coloration of Baijiu through a synergistic application of chromatographic, spectroscopic, and physical methodologies. Aging of Baijiu in earthenware pots involves the infiltration of mineral ions such as iron, aluminum, and calcium; however, these ions are detected at extremely low concentrations and are therefore not linked to the development of Baijiu's yellowish color.
