Integrating morphology, phylogeny, substrate, and distribution: clarifying the major phylogenetic framework of Pluteussect.Hispidoderma (, ) and describing 18 species.

is a genus of wood-rot fungi with considerable ecological importance in forest ecosystems. Within this genus, sectionHispidoderma is distinctively characterized by a specific combination of pileipellis structures (trichoderm, hymeniderm, or trichohymeniderm) and non-metuloid hymenial cystidia, which together provide key morphological basis for section delimitation. In this study, we combined genetic data from three gene regions (large subunit ribosomal RNA [LSU], internal transcribed spacer [ITS], and translation elongation factor 1-alpha []) to construct the major phylogenetic framework of sectionHispidoderma.

Giant Five-Shell Polyoxometalate Cages and the Single-Cluster-Based Nanowire Superstructures.

The preparation of polyoxometalate molecular cages has always been a long-term and challenging pursuit. In this work, we have successfully prepared two unprecedented giant heterogeneous POM-based purely inorganic molecular cages with symmetry, which contain the aggregation of M (M = Ni, Co)-substituted trilacunary {PW} and Mn-bridged {W}. Sodium ions are used as templates to fill the cages.

[Multi-scenario Energy Consumption and Carbon Emission Prediction in Tianjin Based on LEAP Model].

The carbon peaking and carbon neutrality goals require China to reduce energy consumption and reduce carbon emissions. Taking Tianjin as an example, the carbon emission inventory was compiled, and the driving degree of each factor was identified by the logarithmic mean index method （LMDI）. Based on this, combined with scenario analysis, the LEAP-TJ model was constructed to explore the trend of terminal energy consumption and carbon emission in Tianjin from 2022 to 2060.

Designed Synthesis of an Aluminum Molecular Ring Based Rotaxane and Polyrotaxane.

Mechanically interlocked molecules, such as rotaxanes, have drawn significant attention within supramolecular chemistry. Although a variety of macrocycles have been thoroughly explored in rotaxane synthesis, metal-organic macrocycles remain relatively under-investigated. Aluminum molecular rings, with their inner cavities and numerous binding sites, present a promising option for constructing rotaxanes.

Carborane-Cluster-Wrapped Copper Cluster with Cyclodextrin-like Cavities for Chiral Recognition.

Chiral atomically precise metal clusters, known for their remarkable chiroptical properties, hold great potential for applications in chirality recognition. However, advancements in this field have been constrained by the limited exploration of host-guest chemistry, involving metal clusters. This study reports the synthesis of a chiral Cu(CBHS) (denoted as Cu@CB, where CBHSH = 9,12-(HS)-1,2--carborane) cluster by an achiral carboranylthiolate ligand.

Induced Aggregation, Solvent Regulation, and Supracluster Assembly of Aluminum Oxo Clusters.

ConspectusRecent years have witnessed the development of cluster materials as they are atomically precise molecules with uniform size and solution-processability, which are unattainable with traditional nanoparticles or framework materials. The motivation for studying Al(III) chemistry is not only to understand the aggregation process of aluminum in the environment but also to develop novel low-cost materials given its natural abundance. However, the Al-related clusters are underdeveloped compared to the coinage metals, lanthanides, and transition metals.

Assembly of Homochiral Aluminum Oxo Clusters for Circularly Polarized Luminescence.

Chiral aluminum oxo clusters (cAlOCs) are distinguished from other classes of materials on account of their abundance in the earth's crust and their potential for sustainable development. However, the practical synthesis of cAlOCs is rarely known. Herein, we adopt a synergistic coordination strategy by using chiral amino acid ligands as bridges and auxiliary pyridine-2,6-dicarboxylic acid as chelating ligands and successfully isolate an extensive family of cAlOCs.

The environmental sources of benzophenones: Distribution, pretreatment, analysis and removal techniques.

Benzophenones (BPs) have wide practical applications in real human life due to its presence in personal care products, UV-filters, drugs, food packaging bags, etc. It enters the wastewater by daily routine activities such as showering, impacting the whole aquatic system, then posing a threat to human health. Due to this fact, the monitoring and removal of BPs in the environment is quite important.

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.

Electrical Conductivity and pH Are Two of the Main Factors Influencing the Composition of Arbuscular Mycorrhizal Fungal Communities in the Vegetation Succession Series of Songnen Saline-Alkali Grassland.

Arbuscular mycorrhizal fungi (AMF) are widely distributed microorganisms in the soil, playing an important role in vegetation succession, plant community diversity, and improving soil physicochemical properties. In this study, morphological identification and high-throughput sequencing technology were used to comprehensively analyze the AMF community composition and diversity at different succession stages of Songnen saline-alkali grassland. To determine the root colonization status of plants collected in the field, a colonization system was established using late-succession plants as host plants to verify the existence of mycorrhizal symbiosis and the matching phenomenon of AMF in Songnen saline-alkali grassland.

Trihalomethanes in water samples: Recent update on pretreatment and detection methods.

Trihalomethanes (THMs) are classified as volatile organic compounds, considered to be a disinfection by-product during water disinfection process. THMs have been shown to be cytotoxic, genotoxic and mutagenic, with a risk of cancer when they contact with people directly. To protect public health and monitor water quality, it is important to monitor and measure THMs in drinking water.

Cholic acid exposure during late pregnancy causes placental dysfunction and fetal growth restriction by reactive oxygen species-mediated activation of placental GCN2/eIF2α pathway.

Epidemiological studies suggest that fetal growth restriction (FGR) caused by gestational cholestasis is associated with elevated serum cholic acid (CA). Here, we explore the mechanism by which CA induces FGR. Pregnant mice except controls were orally administered with CA daily from gestational day 13 (GD13) to GD17.
