Construction of an MXene/MIL Fe-53/ZIF-67 derived bifunctional electrocatalyst for efficient overall water splitting.

Research on water splitting is paramount for developing low-carbon alternative energy sources. Nevertheless, creating an efficient, cost-effective, and bifunctional electrocatalyst that facilitates both the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) remains an elusive goal. In this work, we report a novel hybrid nanostructured electrocatalyst by combining and pyrolyzing MXene, MIL-53(Fe), and ZIF-67.

Anti-leucine-rich glioma inactivated 1 (anti-LGI1) encephalitis is a rare but treatable type of AE discovered in recent years. Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia.

How digital paywalls shape news coverage.

The internet has significantly transformed how news is produced, consumed, and distributed. As a result, the news industry has transitioned from ad-supported to subscription-based models regulated by digital paywalls. In the light of this disruption, it is crucial to investigate not only how news consumers adapt to this change but also how economic incentives shape content coverage.

Insight into the roles of lactylation in macrophages: functions and clinical implications.

Lactylation, a post-translational modification, has been linked to gene transcription regulation through epigenetic modulation in various pathophysiological processes. The lactylation regulatory proteins, known as writers, erasers, and readers, govern their dynamics by adding, removing, and recognizing lactyl groups on proteins. Macrophages, as cells of the immune system, maintain homeostasis, responding dynamically to diverse internal and external stimuli.

Empowerment in prevention: a qualitative inquiry into Black girl-centred strategies for reducing HIV/STI and drug misuse risk.

Black girls in the United States are disproportionately diagnosed with sexually transmitted infections (STIs), which can increase the risk of contracting HIV (human immunodeficiency virus), compared to adolescent girls of other races. Therefore, this study was designed to understand barriers to impactful HIV/STI and substance use prevention programmes for Black girls. Data was collected between October 2021 and June 2022 from twelve focus groups which included (N = 62) participants who identified as Black and female between the ages of 13 and 18 years old.

Vitamin B6 Alleviates Aflatoxin B1-Induced Impairment of Testis Development by Activating the PI3K/Akt Signaling Pathway.

Aflatoxin B1 (AFB1) is a harmful environmental contaminant known to disrupt gut microbiota and cause health problems. In recent years, the role of vitamin B6 (VB6) in maintaining intestinal and reproductive health has attracted much attention. AFB1 has been found to damage the intestinal barrier and cause inflammation by disrupting the intestinal microbiota, particularly by increasing the abundance of .

SN2-Reaction-Driven Bonding-Heterointerface Strengthens Buried Adhesion and Orientation for Advanced Perovskite Solar Cells.

Traditionally weak buried interaction without customized chemical bonding always goes against the formation of high-quality perovskite film that highly determines the efficiency and stability of perovskite solar cells. To address this issue, herein, we propose a bimolecular nucleophilic substitution reaction (SN2) driving strategy to idealize the robust buried interface by simultaneously decorating underlying substrate and functionalizing [PbX6]4- octahedral framework with iodoacetamide and thiol molecules, respectively. Theoretical and experimental results demonstrate that a strong SN2 reaction between exposed halogen and thiol group in two molecules occurs, which not only benefits the reinforcement of buried adhesion, but also triggers target-point-oriented crystallization, synergistically upgrading the upper perovskite film quality and accelerating interfacial charge extraction-transfer behavior.

Humic Acid with Vertical Adsorption Conformation Enhanced the Transport of Petroleum Hydrocarbon-Contaminated Colloids.

Humic acid (HA) enhances colloidal transport in porous media, yet the mechanisms by which the HA adsorption conformation affects colloid transport remain unclear. This study investigated the influence of HA on the transport of petroleum-hydrocarbon-contaminated soil colloids (TPHs-SC) in saturated sand columns. The presence of TPHs on the colloidal surface occupied adsorption sites, hindering HA from forming a horizontal adsorption conformation, as observed on uncontaminated soil colloids (SC).

Spectral radiance calibration method for spectroradiometers based on diffraction aberration factors correction.

A spectroradiometer serves as a powerful instrument for measuring the spectral radiance of a target. The spectral radiance calibration function determines the measurement accuracy of the spectroradiometer. However, the general full-field calibration method results in higher spectral radiance values when dealing with targets that only partially fill the field of view (FOV).
