Single-Molecule Studies Reveal That Water Starts to Protect Proteins Even at the ppm Level

Abstract A consensus established by extensive thermodynamic and structural studies of proteins and DNA is that water acts as an indispensable structural cofactor rather than a passive solvent for biomolecules. Nevertheless, it remains unclear whether trace water still exerts a st...

Cross‐Phase Impurity–Interphase Regulation for Suppressing Thermally Accelerated Failure in Ni‐Rich Pouch Lithium‐Ion Batteries

ABSTRACT Practical LiNi 0.8 Co 0.1 Mn 0.1 O 2 ||graphite pouch cells suffer rapid degradation under thermal stress because liquid‐phase impurity reactions, electrode interphase failure, and cathode–anode cross‐talk are tightly coupled. However, most strategies are designed to add...

In-situ polymerized fluorinated polyurethane-based gel polymer electrolyte for high-stability lithium metal batteries

A fluorinated polyurethane-based gel polymer electrolyte (GPE) with flame-retardant properties and high interfacial stability for lithium metal batteries (LMBs) is developed by in-situ polymerization of polycaprolactriol, dicyclohexylmethane diisocyanate, and a fluorinated chain...

Delocalized Electronic State Mediated NiCoOOH Enables Selective Urea‐to‐Nitrite Oxidation for Direct Urea Fuel Cells

ABSTRACT Selective oxidation of urea to nitrite (NO 2 − ) rather than N 2 is desireable for Direct urea fuel cells (DUFCs), doubling the electron yield per molecule while suppressing gas accumulation. Herein, we report a NiCoOOH model catalyst in which cobalt incorporation stabil...

Synergistic Regulation of High Dielectric Constant and H‐Aggregation for Efficient and Thickness‐Tolerant Organic Solar Cells

ABSTRACT While the power conversion efficiency (PCE) of organic solar cells (OSCs) has advanced rapidly, their sensitivity with respect to active layer thickness hinders industrial fabrication. Herein, a novel acceptor BMD‐6F was synthesized via molecular engineering of L8‐BO, wh...

Mortise‐and‐Tenon Molecular Joint Covalent Organic Frameworks With Tunable Topology for Photothermal‐Catalytic Cross‐Dehydrogenative Coupling

ABSTRACT The controllable regulation of dimensionality and interpenetration in covalent organic frameworks (COFs) is crucial for optimizing photocatalytic performance, yet the translation of 3D COFs from structural construction to functional customization remains challenging. Her...

Unraveling the Mystery of Near-Infrared Emission in an Antimony Halide Dimer Driven by the Jahn–Teller Effect

Abstract Most zero-dimensional hybrid metal halides enable emission in the first near-infrared (NIR-I) region (650–950 nm), and the shorter wavelengths result in poor photon penetration depth. Here, we report the observation of an NIR-II emission signal (band gap = 1.13 eV) from...

Ultrafast Core–Shell Spin Transfer and Spin-Selective Relaxation in an Endohedral Cage Cluster

Abstract Ultrafast optical control of spin states offers a promising route to molecular-scale magnetic manipulation, yet the mechanisms of laser-driven spin dynamics in atomically precise clusters remain poorly understood. Here, we investigate the ultrafast spin dynamics of the e...

Extracellular matrix–targeted TNC-scFv armoring enhances CAR T cell persistence and antitumor activity in solid tumors

Chimeric antigen receptor T cell (CAR T cell) therapy has shown limited efficacy in solid tumors, largely due to physical and immunosuppressive barriers imposed by the tumor microenvironment (TME). Tenascin-C (TNC), an extracellular matrix protein highly expressed in multiple sol...

Determining the Partial Molar Volume of the Hydrated Electron from First-Principles Simulated Solution Volumes

Abstract The microscopic solvation structure of the hydrated electron remains difficult to characterize directly despite extensive experimental and theoretical efforts. The partial molar volume,V¯e−, provides an indirect thermodynamic probe, but quantitative agreement with experi...

Personalized regulatory guidance during online cloze tasks: Performance, emotions, and exploratory self-efficacy differences

This study examined whether personalized regulatory guidance supports students' performance, emotions, motivation, and strategy use during online cloze tasks, and whether problem-solving self-efficacy is associated with variability in students' responses to such guidance. Forty-e...

Ecological responses of soil bacteria to rapid and slow temperature fluctuations

Abstract Fluctuating temperatures profoundly affect microorganisms’ coexistence, biogeographic distributions and responses to future climate change. However, how microorganisms respond to fluctuating temperatures with different frequencies in natural communities remains unknown....

Cationic High-Entropy Doping Endows O3-Type Na-Ni-Mn-O-Layered Cathode with High Energy Density and Sustainable Sodium Storage

Abstract Although O3-type layered oxides featuring an open framework demonstrate potential as high-capacity cathode materials for sodium-ion batteries, such cathode materials are confronted with commercial limitations, including intricate phase transition mechanisms, structural d...

Study on Photocuring Printing Technology of Polyurethane Acrylate-Based Transparent Braces

A polyurethane acrylate-based photosensitive resin system was developed for 405 nm DLP printing. The formulations were prepared by blending commercial urethane acrylate RT75A with TPO-L, BBOT, and one of four reactive diluents (ACMO, IBOMA, TPGDA, or CTFA). Double-bond conversion...

Promoting psychological well-being in older adults through volunteering: A randomized controlled trial study in Hong Kong.

As Hong Kong faces rapid population aging, promoting psychological well-being among older adults has become a public health priority. Volunteering, as a form of prosocial behavior, may enhance well-being, yet evidence from non-Western contexts is limited. This study examined the...

No‐Till Improved Peanut Flavour Quality and Aroma Through Soil Nitrogen–Microbiome Regulation

ABSTRACT Peanut ( Arachis hypogaea L.) flavour quality is an important determinant of its market value and consumer acceptance. No‐tillage (NT), a widely adopted conservation agricultural practice, reduces soil disturbance and alters soil microbial communities, potentially influe...

Can Non‐Orthogonal Bases Form Stable Skyrmionic Beams?

ABSTRACT Skyrmions, topologically stable spin textures, have recently garnered significant attention in optics, promising robust high‐density information transmission and nontrivial light‐matter interaction. Optical skyrmionic beams have generally been considered to require the s...

First Total Syntheses of Both C10 Epimers of Mycenolide A: Stereochemical Assignment and Reassessment of Its Reported Neuroprotective Activity

Abstract Mycenolide A, a marine-derived 5-substituted butenolide, possesses a remote C10 quaternary stereocenter whose absolute configuration was previously unassigned. Herein, we report the first stereodivergent total syntheses of both C10-epimers of mycenolide A in only nine st...

An association of Liquidambar (Altingiaceae) vegetative and reproductive structures from the Miocene of South China

Liquidambar is a classic example of the eastern Asian–eastern North American biogeographic disjunction, and its fossil record is critical for understanding the evolutionary history and taxonomy of Altingiaceae. In particular, associated vegetative and reproductive fossils provide...
