Myelin-Inspired 3D PEGylation of Framework Nucleic Acids Enables Simultaneous Long Circulation and Rapid Renal Clearance

The rational design of nanomedicines is fundamentally constrained by a physicochemical paradox at the bio-nano interface: strategies to prolong circulation inevitably suppress clearance, often resulting in long-term accumulation and systemic toxicity. To address this, we propose...

Effects of Cr, Al, and Mo on the Mechanical Properties and CO2 Corrosion Resistance of Cr-Al Alloyed Oil Well Tubular Steel

CO2 corrosion is one of the major failure mechanisms affecting oil well tubular steels during oil and gas extraction. Although high-Cr stainless steels exhibit excellent corrosion resistance, their high cost limits practical applications. Therefore, developing economical low-Cr s...

Converting Segregation‐Induced Banding Into Layered Heterostructures for Enhanced Strength‐Toughness Synergy in Low‐Alloy Steel Plates

The strength–ductility–toughness trade‐off remains a central challenge in structural steels, particularly for large‐dimension plates where advanced heterostructure‐processing routes are often difficult to scale. Here, we propose an industrially compatible strategy that converts s...

Weakening conjugation of organic cyclic additives towards advanced aqueous zinc-ion batteries

Aqueous zinc-ion batteries (AZIBs) offer a safe and economical option for energy storage but face zinc dendrites and parasitic reactions. Here we report 1,3,5-tris(2-hydroxyethyl) isocyanurate (THI) as an electrolyte additive that delivers environment-dependent dual-state protect...

Hydrogen-bonded organic framework-reinforced piezoelectric scaffolds for guided in situ bone regeneration

The fibrin network formed during the early bone repair establishes a viscoelastic micromechanical niche that recruits cells and releases cytokines, playing a pivotal role in primary callus formation. However, conventional metallic implants often lack these dynamic, bioactive cues...

Unrestricted Phase Manipulation in Electrically Programmable Terahertz Metadevices via Dual-State Decoupling

Achiral Additives Modulated Helicity and Supramolecular Fibrillation Assembly of Helical Dendronized Poly(phenylacetylene)s through Enhanced Radial Amphiphilicity †

Comprehensive Summary Non‐covalent interactions with additives have been demonstrated to be intriguing in conferring racemic polymers with preferential one‐handed helical conformation. However, these additives are normally chiral, and specific interactions are demanded. We report...

Beyond the “source-sink” paradigm: catalytic mechanism of low-angle tilt grain boundaries in vacancy generation and annihilation

Grain boundary (GB)-vacancy interactions play a pivotal role in tailoring material properties. However, the prevailing paradigm that “GBs function as vacancy sources/sinks” lacks robust atomic-scale evidence, thereby failing to discriminate the intrinsic mechanisms governing vaca...

Revealing Non-Steady-State Structure–Performance Relationship in Plateau-Capacity-Dominated Hard Carbon Anodes for High-Rate Reversible Sodium Storage

Abstract The sodium storage structure–performance relationship of hard carbon anodes has long been regarded as an intrinsic material property and forms the basis for electrode design. This common view, however, does not hold with varying operating temperatures. At room temperatur...
