Constructing Intrinsic Inorganic Superhydrophobicity With Omnipotent Robustness Through Epitaxially‐Grown Fluoride‐Free Ceramics

ABSTRACT Materials with superhydrophobicity have been persistently sought after for their extensive improvements in energy, environment, and other significant fields over the last few decades. Nevertheless, surface modification remains the mainstream approach to achieve low surfa...

Macroevolutionary dynamics of Androsace s.l . (Primulaceae) across the Northern Hemisphere

Abstract Mountain regions of the Northern Hemisphere harbor exceptional biodiversity, yet the processes underlying species diversification and migration among these regions remain poorly understood. This study investigates the macroevolutionary dynamics of Androsace s.l ., a genu...

The role of equatorial juvenile arcs in the Middle Triassic seawater 87Sr/86Sr decline during the Pangean “quiet” period

The Middle Triassic (246−235 Ma) seawater 87Sr/86Sr record exhibits an excursion following the recovery from Siberian large igneous province volcanism. Two primary mechanisms have been proposed to explain the isotopic shift: (1) a change in the 87Sr/86Sr ratio of the continental...

Colossal and ReversibleBarocaloric and Solvent-CaloricEffects in a T C-Adjustable Spin-CrossoverComplex

Abstract Barocaloric effects (BCE) represent an appealing refrigeration technology and have attracted great interest recently. However, most BCE materials still cannot meet real-world refrigeration requirements because of their fixed phase transition temperature TC and the signif...

Kinetically ProgrammedThermoresponsive PolyethyleneGlycol Shedding from Lipid Nanoparticles Improves mRNA Delivery

Abstract Polyethylene glycol (PEG) can stabilize nanoparticles and facilitate transport across biological barriers, yet the same PEG layer suppresses cellular uptake─a trade-off known as the PEG dilemma. Current strategies seek to overcome this limitation by enabling PEG shedding...

ODARRL: Obstacle- and Disturbance-Aware End-to-End Residual Reinforcement Learning for Underwater Robot Trajectory Tracking with Obstacle Avoidance

ROVs are essential for marine exploration and underwater operations, yet conventional teleoperation relies heavily on skilled human operators, and many autonomous methods stop at high-level planning rather than low-level actuation, limiting robustness in disturbed and cluttered e...

Accelerating theDiscovery of Deep-Ultraviolet NonlinearOptical Materials by Combining Machine Learning Interatomic Potentialswith First-Principles Calculations: A Case of LiB2O3F

Abstract Discovering deep-ultraviolet (deep-UV) nonlinear optical (NLO) crystals is hampered by the vast structural search space and the cost of first-principles screening. Here, we establish an integrated framework coupling machine learning interatomic potential (MLIP) construct...

Star PolyelectrolyteCoacervates Enable Adaptive andRobust Enzyme Immobilization for Efficient Biocatalysis

Abstract Enzyme immobilization in solid porous supports often suffers from a trade-off among enzyme loading, mass transport, catalytic activity, and operational stability. Here, we report a liquid-like immobilization platform based on star polyelectrolyte coacervates (SPECs) form...

Sodium Lidar observed multiple sodium layer structures and their dynamical coupling mechanism

Abstract. On the night of 13 June 2013, the University of Science and Technology of China (USTC) sodium lidar observed multiple sporadic sodium layers (SSLs) and enhanced sodium patterns (ESPs) over Hefei, China (31.8°N, 117.3°E). These structures appeared at different times, col...

Ultrasmall PolymericMicelles Enable Noninvasive TransdermalRosiglitazone Delivery via Lipid Fluidization and Transcytosis

Abstract Noninvasive transdermal drug delivery (TDD) offers sustained therapeutic release but is hindered by the stratum corneum (SC) barrier. Herein, we report ultrasmall polymeric micelles (PMs) embedded in poly(vinyl alcohol) hydrogels for the passive TDD of rosiglitazone (RGT...

Highly Efficient Hydrogenation of CO2-Containing Syngas to Liquid Fuels over FeMnK Catalysts

Abstract Converting CO2-containing syngas directly to liquid fuels provides an effective route for carbon-efficient fuel production. However, it is challenging to achieve the simultaneous conversion of CO and CO2 into liquid fuels due to the different activation pathways. Herein,...

Nanoscale Formation,Structure, and Stability of Phosphate-IronColloids at Anoxic-Oxic Interfaces

Abstract The mobility of phosphorus (P) at anoxic–oxic interfaces is largely controlled by the formation of phosphate-iron (Fe) colloids, yet the nanoscale mechanisms underlying their formation, structure, and stability remain poorly described. Here, we systematically investigate...

Modification GeneKnockout Diversifies Piericidinsfrom the Marine-Derived Streptomyces psammoticus SCSIO NS126

Reversible Oxygen Redoxin High Voltage for Lithium-RichLayered Oxides

Abstract Lithium-rich layered oxides, characterized by Li ions in the transition-metal layers, can significantly increase battery energy density through the introduction of oxygen redox. However, these cathodes often suffer from substantial voltage hysteresis, leading to a consid...

Modulation of leaf economics spectrum, mycorrhizal type, and phylogeny on leaf nutrient resorption in a temperate urban forest

Abstract Background and Aims Nutrient resorption is a key nutrient conservation strategy employed by plants. However, the leaf economics spectrum (LES), which reflects a fundamental trade-off between resource acquisition and conservation in plants, has not been properly linked to...

Long-Range Synchronization of Remote NV Color-Center Ensembles via an Active Microwave Cavity

For scalable quantum networks and distributed quantum sensing, remote NV color-center spin ensembles require controllable long-range coherent connections. However, the magnetic dipole coupling between NV centers decays rapidly with distance, making direct stable coherent exchange...
