Ammonium Chloride and Peroxide: A Metal‐Free Aqueous Strategy for Oxime Synthesis

A metal‐free, aqueous protocol enables the synthesis of oximes from carbonyls using NH 4 Cl and H 2 O 2 . A radical mechanism involving in situ hydroxylamine generation bypasses the use of unstable salts. Monoethanolamine (MEA) serves as an essential additive, facilitating the co...

Cobalt-Loaded Peanut Shell Biochar Enables Nonradical Peroxymonosulfate Activation for Rapid Tetracycline Degradation

Abstract Conventional peroxymonosulfate (PMS) activation systems are often dominated by nonselective radical pathways, which limit oxidation efficiency. Herein, a cobalt-loaded peanut shell biochar (Co-BC) was synthesized via a co─impregnation–pyrolysis strategy for efficient PMS...

Interfacially Assembled Hollow AuAg Nanostars on Flexible PDMS for Sensitive SERS Detection

Optimizing the morphology and structure of noble metal nanomaterials is critical for the design of high-performance surface-enhanced Raman scattering (SERS) substrates for trace analyte detection. A plasmon-tunable SERS platform consisting of AuAg alloy nanostars anchored on a hy...

Angle-robust photovoltaics via Mie resonance hybridization for stable power output in perovskite solar cells

Perovskite solar cells (PSCs) have attracted intensive research interest as a promising candidate for next-generation photovoltaic technologies, offering high power conversion efficiency ( PCE ) and low manufacturing cost. However, the practical energy yield of conventional plana...

Machine-learning classification of myocardial infarction and ST/T-change ECG phenotypes across complementary evaluation settings

The primary PTB-XL outcome was an operational ECG phenotype defined by myocardial infarction and/or ST/T-change diagnostic superclass labels, rather than adjudicated active ischemia. Public ECG datasets were harmonized to 10-s, 12-lead, 100-Hz inputs. Patient-disjoint PTB-XL part...

The Combined Strategy of Baicalin and Oxacillin Sodium Against Methicillin-Resistant Staphylococcus aureus: Biofilm Inhibition, Virulence Attenuation and In Vivo Anti-Infection Efficacy

Over the past few years, considerable scholarly interest has been directed toward the synergistic application of natural compounds alongside conventional antibiotics to address infections stemming from multidrug-resistant (MDR) pathogens. The primary objective of this research is...

Construction of a 0D/2D S-Scheme Heterojunction Based on Ni-Doped CsPbBr3 and ZnO for Enhanced Photocatalytic CO2 Reduction

Abstract Doping with transition metals and constructing S-scheme heterojunctions are well-recognized strategies for boosting photocatalytic CO2 reduction. Herein, we adopt a cascade design approach to fabricate a Ni-doped CsPbBr3/ZnO S-scheme heterojunction, aiming to further imp...

N -Shaped vs Λ-Shaped Bridging Symmetric Molecules: Geometric Compatibility Drives Performance Improvement in Perovskite Solar Cells

Abstract Intrinsic defects limit the further improvement of photovoltaic performance and stability of perovskite solar cells (PSCs). Bridging symmetric molecules have been proved to be a kind of promising additive for passivating defects within perovskites. However, there is curr...

Harmonizing A‑Site Cation Incorporation With Conductive Grain‑Boundary Bridging for Durable Perovskite Solar Cells

ABSTRACT While perovskite solar cells (PSCs) have achieved significant progress in power conversion efficiency ( PCE ), their commercialization remains hindered by a critical challenge: irreversible efficiency degradation during device operation, primarily caused by the spontaneo...

Strain‐Mediated Electronic Structure Reconstruction of Frenkel Defects in Monolayer MoSe 2 : A First‐Principles Study

ABSTRACT Using first‐principles DFT, we investigate the synergistic modulation of the electronic structure of monolayer MoSe 2 by biaxial strain and Frenkel defects for electrocatalytic hydrogen evolution. A biaxial compressive strain of −4% lowers the Frenkel defect formation en...

Leaf-Root Trait Coordination Among Dominant Herbaceous Species Across Three Marsh Habitats in Northeast China

Plant functional traits are key indicators of plant responses to environmental conditions and resource-allocation trade-offs, thereby providing insights into adaptive mechanisms across habitats. Wetlands are one of the major habitats worldwide, yet organ-level plant life adaptive...

Mitigation of ammonia and nitrous oxide emissions and cutdown of composting cycle during Enteromorpha prolifera composting with the co-addition of attapulgite and biochar

Abstract Since 2007, annual blooms of the green macroalga Enteromorpha prolifera have occurred in China’s coastal waters, posing serious threats to local aquaculture and ecological environment. Composting is an ideal way for managing E. prolifera waste. This study explored how at...

Synthesis of Unsymmetrical Alkyl Carbonate from Diethyl Carbonate and Benzyl Alcohol with N-Doped Carbon-Supported Iron Oxide Catalysts

Developing simple and efficient heterogeneous catalysts for transesterification of dialkyl carbonates with alcohols is very significant for achieving green syntheses of unsymmetrical alkyl carbonates. Here, a set of N-doped carbon material (NCM)-supported iron oxides was prepared...

Contribution of Urbanization and Large‐Scale Warming to Temperature Increase From Pre‐Industrial Revolution Time to Recent Period in Central Beijing City

Abstract The annual mean Surface Air Temperature (SAT) observed during 1757–1762 in central Beijing was 3.1°C lower than that of the nearby Autonomous Weather Stations (AWS) in recent 6 years (2015–2020). The change was much larger than the averaged global warming of the past cen...
