Enantioselective and Divergent Synthesis of Propargylamides and Allenamides from Alkynyl Diazoketones and Anilines via Organocatalytic Wolff Rearrangements

Abstract Chiral allenes and alkynes are privileged scaffolds in natural products and pharmaceuticals. Although significant advances have been achieved in catalytic asymmetric synthesis from diazo compounds, selectively achieving high levels of both enantioselectivity and regiosel...

Robust 4f-2p-3d electron ladder for boosting the stability of oxygen electrocatalysis

Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are recognized as the core bifunctional catalytic processes in metal-air batteries, yet their inferior stability severely limits the large-scale deployment of these frontier devices. For resolving it, a bifunctio...

Graphitization of nitrogen-bearing organic-like carbonaceous material in a dust particle from Chang’e-6 lunar samples

Abstract The delivery and evolution of carbonaceous materials to airless planetary bodies remain poorly constrained. This study characterized a porous, aggregated, carbon-rich dust particle (CE6-CDP) from Chang’e-6 lunar samples. CE6-CDP yielded a mean δ13CVPDB value of − 25.92 ±...

Functional niche partitioning influences species turnover across supraglacial microbial communities on the Longxiazai glacier, Tibetan Plateau

Glaciers represent unique ecosystems harboring diverse microbial communities that dominate biomass and drive biogeochemical cycling across supraglacial habitats. These microbes transform deposited modern and ancient carbon/nitrogen, and these elements are subsequently transferred...

Diagnosing CESM2 Biases in Northwest Indian Ocean Warming and Its Implications for India Summer Monsoon Precipitation

Abstract Declining monsoon rainfall over agriculture‐dependent Eastern Central India (ECI) during 1901–2014 threatens regional food and water security. Observations link ECI drying to rapid Northwest Indian Ocean (NWIO) warming, which weakens monsoon circulation. However, the wid...

Energy Funneling between Distinct Exciton States in Monophase 2D Lead Halide Hybrid Perovskites Induced by Lattice Distortion

Abstract Energy funneling holds strong promise for highly efficient energy conversion and light-emitting devices. Owing to their unmatched structural diversity, lead halide perovskites constitute an ideal platform to explore energy funneling phenomena and applications, a prominen...

cTIRF: TIRF-Like Computational Optical Sectioning for Widefield Fluorescence Microscopy

Abstract The resolving ability of widefield fluorescence microscopy is fundamentally limited by out-of-focus background owing to its low axial resolution, particularly for densely labeled biological samples. Although total internal reflection fluorescence (TIRF) microscopy provid...

Liquid Metal Molecular Medicine

ABSTRACT Biomolecules are central to disease onset, diagnosis, and treatment, yet materials capable of actively interacting with biological targets remain limited. Gallium‐based liquid metals and their derivative composites possess a metallic liquid core, a dynamic oxide interfac...

A Li metal-SiO x hybrid anode enabling synergistic plating/alloying dual-mechanism lithium storage

Balancing specific energy and cycle durability remains a critical challenge for practical battery systems, as conventional single-mechanism anodes struggle to optimize both simultaneously. Here, we engineer a symbiotic Li-SiO x hybrid anode enabling spatiotemporally coordinated L...

In vivo magnetic recording of neuronal action potentials using a differential TMR magnetrode

Abstract Neuronal magnetic signal recording intrinsically provides vector information and tissue transparency, offering a potential route to overcome the spatial resolution limitations of conventional electrophysiological recordings. However, in situ detection of neuronal magneti...

Stage-specific Cyanobacterial Handoffs and Heterotrophic Subsidies Underpin Biocrust Carbon Accumulation

Abstract Inoculating cyanobacteria is a widely adopted strategy to accelerate biocrust formation and restore dryland soil functions, yet the in situ mechanisms sustaining microbial biomass carbon (MBC) accumulation under seasonal stress remain poorly understood. Here, we combined...

Ultrahigh On/Off Ratio Oxide Transistors via Noncoplanar Schottky–Ohmic Contacts

Abstract Simultaneously balancing high mobility and ultra-low leakage current is a major challenge for metal-oxide thin-film transistors (TFTs) in ultra-low-power applications. Herein, we construct a high-performance InGaZnO/InGaO/InGaZnO tri-layer TFT based on a noncoplanar Scho...

Postcranial osteology of the giant oviraptorosaur Gigantoraptor erlianensis

Gigantoraptor erlianensis is an unexpectedly large-bodied oviraptorosaurian dinosaur from the Late Cretaceous of Inner Mongolia, China. Exhibiting a bizarre body plan, G. erlianensis is key to revealing the high morphological disparity and complex evolutionary history near the tr...

Core–Shell Nanofibrous Membranes for Dynamic Intestinal Organ-on-a-Chip Culture

Abstract Organ-on-a-chip (OOC) systems rely on membrane-supported tissue interfaces to replicate organ-level barrier functions in vitro. However, conventional porous membranes often provide limited biological cues for cell adhesion and may require an extracellular matrix coating....

Molecular Design for the Multidimensional Modulation of Supramolecular Nanoparticle Interactions

Abstract Surface ligand engineering based on reversible supramolecular hydrogen bonding provides a versatile strategy for programmable nanoparticle (NP) self-assembly, yet quantitatively linking the molecular structure to interparticle interactions remains challenging. Here, expl...

A Comparative Study of Machine-Learning Methods for Early Classification from Sparse Astronomical Light Curves

The booming data volume of modern time-domain surveys demands fast, robust early classification of sparsely sampled light curves, as newly discovered transients typically have only a handful of observations. We compare classifiers for extremely sparse light curves (3–30 observati...

Crystallization Manipulation Through Buried Pyridinium‐Induced Tunable Interactions in Perovskite Solar Cells

ABSTRACT The interaction between the hybrid component of self‐assembled monolayers (SAMs) and the perovskite precursor could delay the crystallization process, resulting in high‐quality perovskite film and highly efficient perovskite solar cells (PSCs). However, the intensity of...

Lakeshore transformation and water color dynamics: A satellite-based 23-year assessment of nine plateau lakes in Yunnan, China

Study region Nine plateau lakes in Yunnan, China. Study focus We developed an extended lakeshore utilization classification framework to categorize lakeshores as natural, agricultural, or artificial using fixed maximum shorelines. We then derived the Forel–Ule Index (FUI) of the...
