Unveiling airborne threats: Vertical profiles of multiple emerging pollutants in PM across the urban atmosphere of Southern China.

PM has a detrimental impact on human health and has become a focus of widespread concern. The tempo-spatial distribution of emerging pollutants has been extensively studied, while there is a scarcity of understanding their vertical distribution in atmospheric environment. Here we investigated the vertical profiles of phthalate esters (PAEs), organophosphate esters (OPEs), neonicotinoids (NEOs), and per-and polyfluorinated substances (PFASs) in PM at ground level (4.

Genomic analysis of Zhou8425B, a key founder parent, reveals its genetic contributions to elite agronomic traits in wheat breeding.

High-quality genome information is essential for efficiently deciphering and improving crop traits. Here we report a highly contiguous and accurate hexaploid genome assembly for the key wheat breeding parent Zhou8425B, an elite 1BL/1RS translocation line with durable adult plant resistance (APR) against yellow rust (YR) disease. By integrating HiFi and Hi-C sequencing reads, a 14.

3D Ordered Macroporous Mn, Zr-Doped CaCO Nanomaterials for Stable Thermochemical Energy Storage.

Developing high-performance Ca-based materials that can work for long-term heat transfer and storage in concentrated solar power plants is crucial to achieve the large-scale conversion of solar photon fluxes to dispatchable electricity. This work demonstrates that a series of Mn, Zr co-doped CaCO nanomaterials with the 3D ordered macroporous (3DOM) skeletons are successfully prepared by a novel strategy of templated metal salt co-precipitation. The characterization results indicate that a majority of Zr and Mn are atomically dispersed into the highly-crystallized CaCO framework, whereas a minor amount of Mn is present in the form of CaMnO nanoparticles (NPs).

High-Spin States of Manganese(III) Enable Robust Cold-Adapted Activity of MnO Nanozymes.

Developing novel cold-adapted nanozymes and elucidating their mechanisms of action remains a great challenge. Inspired by natural oxidases that utilize high-spin and high-valent metal-oxygen intermediates to achieve high efficiency at low temperatures, in this study, a series of MnO nanomaterials with varied valence and spin states are synthesized. The activity assay revealed that the oxygen vacancy-engineered ε-MnO nanozyme displayed excellent cold-adapted oxidase-like properties, and no observable activity loss is observed in the temperature range of -20 to 45 °C.

Barriers and Facilitators in the Use of Selected Point-of-care Diagnostics in Indian Public Health Programs.

Background: Comprehensive reviews on the use and utility of point-of-care tests (POCs) in public health programs in relation to infectious disease and nutrition are limited. Point-of-care technologies have potential to improve the management of infectious diseases particularly in settings where healthcare infrastructure and timely access to quality medical care are limited.

Methods: We aim to describe POC tests currently used or under evaluation in the Indian national programs for communicable diseases and nutrition, and to identify the barriers and facilitators.
