Multi-omics profiling reveals elevated CO-enhanced tolerance of Trifolium repens L. to lead stress through environment-plant-microbiome interactions.

The increasing atmospheric CO resulting from human activities over the past two centuries, which is projected to persist, has significant implications for plant physiology. However, our predictive understanding of how elevated CO (eCO) modifies plant tolerance to metal stress remains limited. In this study, we collected roots and rhizosphere soils from Trifolium repens L.

Research on motion target detection based on infrared biomimetic compound eye camera.

The cooled mid-wave infrared biomimetic compound eye camera has wide range of applications, such as industrial inspection, military project, and security. Due to the low resolution of individual eyes and the large field view of the imaging system, existing motion target enhancement and detection algorithms cannot effectively detect all potential targets. To address this issue, we propose an improved elementary motion detector model that combines a double-layer ON_OFF channel and a cross-type computational architecture, which is able to suppress a stationary background and enhance moving targets.

Buckling cluster-based H-bonded icosahedral capsules and their propagation to a robust zeolite-like supramolecular framework.

Hydrogen-bonded assembly of multiple components into well-defined icosahedral capsules akin to virus capsids has been elusive. In parallel, constructing robust zeolitic-like cluster-based supramolecular frameworks (CSFs) without any coordination covalent bonding linkages remains challenging. Herein, we report a cluster-based pseudoicosahedral H-bonded capsule Cu, which is buckled by the self-organization of judiciously designed constituent copper clusters and anions.

Bottom-up construction of chiral metal-peptide assemblies from metal cluster motifs.

The exploration of artificial metal-peptide assemblies (MPAs) is one of the most exciting fields because of their great potential for simulating the dynamics and functionality of natural proteins. However, unfavorable enthalpy changes make forming discrete complexes with large and adaptable cavities from flexible peptide ligands challenging. Here, we present a strategy integrating metal-cluster building blocks and peptides to create chiral metal-peptide assemblies and get a family of enantiopure [R-/S-NiL] (n = 2, 3, 6) MPAs, including the R-/S-NiL capsule, the S-NiL trigonal prism, and the R-/S-NiL octahedron cage.

Two structurally new Lindqvist hexaniobate-templated silver thiolate clusters.

Two structurally new Lindqvist hexaniobate-templated silver thiolate clusters, [NbO@Ag(PrS)(CHCOO)] (Ag) and (HO)[NbO@AgKSO(HO)(PrS)(CHCOO)] (Ag), were synthesized using a facile one-pot solvothermal approach. Single crystal X-ray diffraction analyses revealed the presence of a classical Lindqvist-type [NbO] anion template, with PrS and CHCOO surface-protecting ligands in both silver clusters, which can further form two-dimensional Ag assembly and one-dimensional Ag chain packing structures. Both Ag and Ag clusters exhibited intriguing photothermal conversion properties and temperature-dependent emission behavior.

Semi-permeable membrane-covered high-temperature aerobic composting: A review.

Semi-permeable membrane-covered high-temperature aerobic composting (SMHC) is a suitable technology for the safe treatment and disposal of organic solid waste as well as for improving the quality of the final compost. This paper presents a comprehensive summary of the impact of semi-permeable membranes centered on expanded polytetrafluoroethylene (e-PTFE) on compost physicochemical properties, carbon and nitrogen transformations, greenhouse gas emission reduction, microbial community succession, antibiotic removal, and antibiotic resistance genes migration. It is worth noting that the semi-permeable membrane can form a micro-positive pressure environment under the membrane, promote the uniform distribution of air in the heap, reduce the proportion of anaerobic area in the heap, improve the decomposition rate of organic matter, accelerate the decomposition of compost and improve the quality of compost.

Supracluster Assembly of Archimedean Cages with 72 Hydrogen Bonds for the Aldol Addition Reaction.

Clusters that can be experimentally precisely characterized and theoretically accurately calculated are essential to understanding the relationship between material structure and function. Here, we propose the concept of "supraclusters", which aim to connect "supramolecules" and "suprananoparticles" as well as reveal the unique assembly behavior of "supraclusters" with nanoparticle size at the molecular level. The implementation of supraclusters is full of challenges due to the difficulty in satisfying the ordered connectivity of clusters due to their abundant and dispersed hydrogen bonding sites.
