Synthesis of Pyrroloquinazolinones via Base-Promoted Domino Reaction of 7-Vinylindoles with In Situ Formed Isocyanates from Dioxazolones

Abstract Herein, we report a novel base-promoted domino reaction between 7-vinylindoles and dioxazolones, enabling the efficient one-pot synthesis of pyrroloquinazolinone scaffolds in moderate to excellent yields (up to 95%). This transition-metal-free protocol employs readily av...

Declining Small-Stem Abundance and Contrasting Intraspecific Spatial Dynamics in a Tropical Montane Rainforest on Hainan Island, China

Dispersal limitation, habitat heterogeneity, and density-dependent processes shape tree distributions, but their spatial signatures can overlap with those of vegetative reproduction. We examined diameter structure and intraspecific spatial patterns of eight dominant species using...

Cascade In Situ Iodination and Elemental Copper-Mediated Reductive Coupling for the Synthesis of 3-Difluoroacetate-Functionalized Chromones

Abstract Reported in this paper is an I2/Cu-mediated method for the synthesis of 3-difluoroacetate-functionalized chromones via cascade reactions between o-hydroxyaryl enaminones and alkyl difluoroacetates. The product construction involves a key in situ iodination generating 3-i...

Association between residential greenspace exposure and cognitive health in older adults: evidence from Nanjing, China

Amidst global population aging, cognitive function decline among older adults has emerged as a critical public health challenge. Greenspace (GS) may represent an important environmental correlate of cognitive health. Given the restricted mobility of many older adults, their resid...

Influence of steam on nature of coke formed in thermal conversion of ethanol using Ni/SBA-15 catalyst

In steam reforming, polymerization/cracking of reactant could take place in parallel with reforming reactions, which are important routes for coking and might form coke of distinct nature with that from reforming. This study investigated the decomposition or steam reforming of et...

Solvent‐Free, UV‐Curable Cellulosic Adhesives Engineered via a Supramolecular Eutectic Platform for Robust Adhesion

ABSTRACT Cellulose‐based adhesives offer sustainable alternatives to petroleum‐derived products but face bottlenecks regarding organic solvent reliance, slow curing efficiency, and moisture sensitivity. Here, a solvent‐free, UV‐curable cellulosic adhesive (UCA) is developed via a...

Flue Gas Torrefaction of Corn Stover-Densified Fuel: Impacts on Physicochemical Properties and Combustion Performance

Abstract Corn stover pellets were torrefied under a simulated flue gas atmosphere (220 °C–300 °C, 15–25 min) to evaluate physicochemical and combustion modifications. Analyses revealed that increasing torrefaction severity significantly reduced the volatile matter, hydrogen, and...

Recent advances in TPT-based crystalline hybrid materials: from structural design to functional applications

2,4,6-Tri(4-pyridyl)-1,3,5-triazine (TPT), featuring a rigid C 3 -symmetric π-conjugated skeleton, an electron-deficient triazine core, and three pyridyl coordination sites, has emerged as a powerful building block for the construction of crystalline hybrid materials. The unique...

Rising Connectivity, Shifting Hubs: The Evolving Network and Governance Challenges of Global Wild‐Sourced Trade

ABSTRACT Global wild‐sourced wildlife trade is structured not only by the intensity and composition of traded species, but also by the routes, hubs, and redistribution pathways that connect countries/territories into an intricate network. Understanding the spatiotemporal dynamics...

Beyond Structural Symmetry: Elastic Spatio-Temporal Fluid Graph Convolutional Networks for Skeleton-Based Action Recognition

Skeleton-based human action recognition is a pivotal research area in computer vision. While conventional methods predominantly model human actions as rigid displacements strictly adhering to structural symmetry, the essence of authentic action is actually an elastic spatio-tempo...

Orbital Coupling Over N‐Bridged Zn─Co Atomic Pairs Enables Lignocellulose Valorization

ABSTRACT Production of monophenols and carbohydrates through reductive catalytic fractionation is the key operation for lignocellulose utilization. Metal utilization can be maximized by single‐atom catalysts, but catalytic performance is limited by the insufficient activation cap...

Functional study of the MsCYP9A319 in Micromelalopha sieversi in response to tannic acid stress

Abstract Micromelalopha sieversi (Staudinger) is a major forest pest causing severe damage to poplar plantations in China. However, the molecular mechanisms underlying its adaptation to plant secondary metabolites remain largely unclear. In this study, a P450 gene designated MsCY...

Forest Dieback in Northern Russia: Causes and Potential Uses of Dieback Timber

Studying the causes of forest dieback in Norway spruce (Pícea ábies) and Scots pine (Pinus sylvestris) stands is crucial for predicting their occurrence, promoting sustainable forest management and reforestation, and investigating the properties of forest products derived from fa...

Contributor Turnover Confounds Temporal Comparison of Recorded Habitats: A Voucher-Based Case Study of Three Lycoris Species in China from 2010 to 2020

Temporal comparisons drawn from aggregated occurrence databases assume that the records compared were produced by a comparable community of collectors. We tested that assumption using 297 voucher-backed records of Lycoris radiata, L. aurea, and L. chinensis retrieved from the Chi...

Dual northward overseas radiation from Japanese islands shaped the phylogeography of North-East Asian tree frog

The tree frog Dryophytes japonicus has a broad geographic distribution in northeastern Asia, comprising two major genetically divergent clades whose geographic boundary is located within the Japanese mainland. However, the evolutionary and adaptive mechanisms underlying this wide...
