Ni-Mediated RedoxEngineering Enabled In Situ Constructionof Oxygen Vacancies on MnO/C for Furfural Selective Hydrogenationin Ethanol

Abstract The selective hydrogenation of biomass-derived furfural (FF) to high-value furfuryl alcohol (FA) is critical for the sustainable production of furan-based chemicals. However, designing a catalyst that can selectively hydrogenate C═O bonds is still a huge challenge. Herei...

Reconciling strong coordination and anion-reinforced solvation structure enables nonflammable electrolytes for potassium-ion batteries

Nonflammable electrolytes are pivotal for improving the safety of potassium-ion batteries. However, their broad adoption has been hindered by the inadequate electrode compatibility of conventional nonflammable electrolytes, which typically result from strong solvation and excessi...

Bioactive PdPt nanosheets for hypoxia modulation-enhanced radiotherapy

With the global rise in cancer incidence, the development of effective and safe therapeutic strategies remains an urgent priority. Although radiotherapy (RT) is widely used in clinical oncology, its therapeutic efficacy is often compromised by the hypoxic tumor microenvironment,...

Multifunctional Diluent Enables High‐Voltage and Flame‐Retardant Potassium‐Ion Batteries

ABSTRACT Potassium‐ion batteries (PIBs) emerge as a highly promising candidate system in large‐scale energy storage, owing to their abundant resources, low cost, and potentially high operating voltage. However, the current development of PIBs still faces core bottlenecks such as...

In Situ Sodiation of CoSe 2 Modulating Charge Transfer in Sodium−Selenium Batteries

ABSTRACT Selenized polyacrylonitrile (SePAN), characterized by the unique C−Se covalent bonds, can suppress the formation of polyselenides and their associated shuttle effect in sodium−selenium (Na−Se) batteries. However, its polymeric structure and distinct conversion mechanism...

A Real-Time Single Image Haze Removal Accelerator for Increasingly Automated Vehicles

Autonomous vehicles at L2 and above are increasingly relying on stereo vision systems, where haze removal is critical to detect obstacles hidden in fog. Existing image haze removal techniques have low processing speed and high resource consumption, restricting their application s...

Flexible Membrane-IntegratedZipper CHA Amplificationfor Rapid and Sensitive MicroRNA Detection

Abstract Catalytic hairpin assembly (CHA) is a widely employed signal amplification strategy for developing highly sensitive DNA biosensors, holding great promise for early disease diagnosis. However, conventional CHA systems often suffer from slow reaction kinetics, high nonspec...

Peukert‐Informed Prediction and Screening of Manganese‐Based High‐Rate Potassium Cathode

ABSTRACT Manganese‐based layered oxides have emerged as promising cathode materials for potassium‐ion batteries owing to their low cost, environmental benignity, structural diversity, and high theoretical capacity, yet suffer from poor rate performance. Compositional regulation o...

Establishing the role of ZBTB20 mutations in GnRH deficiency and impaired neurogenesis in the subventricular zone: a human cohort and animal model study

Background Congenital hypogonadotropic hypogonadism (CHH) arises from defective development or dysfunction of GnRH neurons. Olfactory bulb (OB) malformations frequently accompany CHH, a condition termed Kallmann syndrome (KS). Nevertheless, approximately 50% of CHH cases remain g...

A Parallel‐Computing Based Topology Optimization Method of Bi‐Modulus Material Structures With Large Property Difference

ABSTRACT Engineering materials frequently exhibit considerable disparities between their tensile and compressive moduli. However, there are some difficulties in existing topology optimization methods for material structures with large disparities between their tensile and compres...
