Strain engineering in two-dimensional nanomaterials holds significant potential for modulating the lattice and band structure, particularly through localized strain, which enables modulation at specific regions. Despite the remarkable effects of local strain, the relationships among local strain, spatial correlation of photogenerated charge carriers, and photocatalytic performance remain elusive. The current study coupled single-molecule localization microscopy with coordinate-based colocalization (CBC) analysis to explain these relationships.

Introducing vacancies has emerged as one of the valid strategies to modulate the photocatalytic performance of graphitic carbon nitride (g-CN). Introduction of nitrogen vacancies into g-CN can create defect energy levels and trap electrons, consequently accelerating the separation of e/h pairs and effectively boosting photocatalytic activity. Nitrogen vacancies can also serve as adsorption active sites, enhancing the adsorption capacity of the catalyst towards the target molecule (CO).

Article Synopsis
  • - Neuraminidase (NA) is a key glycoprotein in the influenza virus that aids in replication, yet existing vaccines mainly target hemagglutinin (HA) instead of NA despite evidence linking NA antibodies to disease resistance.
  • - Research showed that recombinant NA (rNA) is effective in eliciting immune responses in naïve mice and ferrets, even among those with existing immunity.
  • - When rNA was added to a traditional HA-based vaccine, it significantly enhanced NA-specific immune responses in ferrets without compromising HA-specific immunity, suggesting a potential improvement in vaccine effectiveness.

To systematically characterize the loss of tissue integrity and organ dysfunction resulting from aging, we produced an in-depth spatial transcriptomic profile of nine tissues in male mice during aging. We showed that senescence-sensitive spots (SSSs) colocalized with elevated entropy in organizational structure and that the aggregation of immunoglobulin-expressing cells is a characteristic feature of the microenvironment surrounding SSSs. Immunoglobulin G (IgG) accumulated across the aged tissues in both male and female mice, and a similar phenomenon was observed in human tissues, suggesting the potential of the abnormal elevation of immunoglobulins as an evolutionarily conserved feature in aging.

Background: Phosphatidylserine (PS) is a procoagulant phospholipid enriched on surfaces of activated vascular cells including platelets, endothelium, monocytes, and microvesicles. As a molecular driver of thrombosis accessible to drug blockade, PS is an attractive pharmacologic target for modulating thrombogenesis, with potentially reduced bleeding risk compared to anticoagulant and antiplatelet therapies.

The analysis of terrestrial ecosystem carbon dynamics, based on scarce carbon flux observations or carbon flux products simulated by reanalysis meteorological data, has great uncertainties. A more accurate understanding of carbon dynamics in Eurasia was achieved by using a carbon flux dataset (CFD) from meteorological stations with quasi-observational characteristics. The growth of net carbon uptake of ecosystems over Eurasia has been decreasing since the early 2000s.

Article Synopsis
  • - The study investigates how different types of organic materials impact soil carbon storage and microbial communities in urban greenspaces, revealing significant increases in soil organic carbon (SOC) content, by up to 87%, compared to control conditions.
  • - Seven organic treatments were tested, with BioChar and GreenWasteCompost showing the highest efficiency in carbon sequestration, while microbial necromass levels varied depending on the type of organic material used.
  • - It was found that while microbial necromass increased with organic amendments, its contribution to SOC was negatively influenced by the type of organic material, indicating that more complex organic inputs may limit the role of microbes in carbon storage enhancement.

Graphite phase carbon nitride (g-CN) is a highly promising metal-free photocatalyst, but its low activity, due to limited quantum efficiency and small specific surface area, restricts its practical application. While exfoliating bulk crystals into porous thin-layer nanosheets and incorporating dopants have been shown to improve photocatalytic efficiency, these methods are typically complex, time-consuming, and costly processes. In this study, we developed a simple approach to synthesize oxygen-doped porous g-CN (OCN) nanosheets.

Indoor air pollution, predominantly caused by volatile organic compounds (VOCs), poses significant health hazards when concentrations surpass critical thresholds. Using waste corn straw as carbon source and urea as nitrogen source, straw derived carbon aerogel (CAGH) loaded with g-CN was successfully prepared by hydrothermal and water-assisted calcination. Following water-assisted regulation, g-CN on CAGH exhibited a mixed structure comprising honeycomb and two-dimensional filaments, while the growth of g-CN was uniformly distributed on carbon aerogel in a line-surface combination fashion.

Millions of people globally are exposed to the proven human carcinogen arsenic at unacceptable levels in drinking water. In contrast, arsenic is a poor rodent carcinogen, requiring >100-fold higher doses for tumor induction, which may be explained by toxicokinetic differences between humans and mice. The human ATP-binding cassette subfamily C (ABCC) transporter hABCC4 mediates the cellular efflux of a diverse array of metabolites, including the glutathione (GSH) conjugate of the highly toxic monomethylarsonous acid (MMA), monomethylarsenic diglutathione [MMA(GS)], and the major human urinary arsenic metabolite dimethylarsinic acid (DMA).

The construction of ultra-close 2D atomic-thickness Van der Waals heterojunctions with high-speed charge transfer still faces challenges. Here, we synthesized single-layer ZnInS and g-CN, and introduced silver single atoms to regulate Van der Waals heterojunctions at the atomic level to optimize charge transfer and catalytic activity. At the atomic scale, the impact of detailed structural differences between the two characteristic surfaces of ZnInS ([Zn-S] and [In-S]) on catalytic performance has been first proposed.
