Atomic-scale evidence for continuous surface dislocations in crystalline interfaces

In interfacial dislocation theory, misfit dislocations are conventionally perceived only as discrete arrays, derivable from the quantized Frank-Bilby equation (FBE), largely because experiments and atomistic simulations can usually resolve only well-separated, discrete dislocatio...

Activating Ionic Carbon Nitrides via Epitaxial Dyadic Coupling for Efficient Solar‐Driven H 2 O 2 Generation

ABSTRACT Solar hydrogen peroxide synthesis is a sustainable alternative to the anthraquinone process, yet its efficiency is limited by charge separation and transport in polymeric photocatalysts. Ionic carbon nitrides like poly(heptazine imide) (PHI) offer tunable structures and...

ConjugatedCoordination Polymer Aerogels with UnsaturatedSingle-Atom Metal Sites for Efficient Neutral Oxygen Evolution

Abstract Designing high-performance single-atom catalysts with a precisely designed configuration is important in extensive energy-conversion technologies, which presents enormous potentials to be extensively applied. Defect-enriched conjugated coordination polymer aerogels (d-CC...

Spiky Bursts of Energetic Electron Beams Upstream of Nonstationary Quasi‐Perpendicular Shocks

Abstract Energetic electron beams play a crucial role in collisionless shocks by driving upstream plasma waves and providing seed populations for diffusive shock acceleration. However, the processes responsible for their generation at quasi‐perpendicular shocks remain poorly unde...

Advances in Cyclic Peptides Targeting G Protein‐Coupled Receptors

Peptide‐responsive G protein‐coupled receptors (GPCRs) often recognize endogenous peptide ligands through extended receptor interfaces, providing opportunities for peptide‐based ligands to engage receptor contacts that conventional small molecules struggle to access effectively....

Photon-Induced Modulationof Reaction Pathways inRuthenium Homologous Heteroclusters with a Ruδ+-Ru0 Interface for Photothermal Dry Reforming of Methane

Abstract Photothermal dry reforming of methane (PDRM) is a promising technology for mitigating greenhouse gas (CH4 and CO2) emissions and generating syngas under mild conditions. However, it faces challenges from the catalyst deactivation because of carbon deposition and unbalanc...

HydrogenBonding Networks Formed by Hydroxyl-FunctionalizedN-Heterocyclic Carbenes on Ag(111)

Abstract N-Heterocyclic carbenes (NHCs) have emerged as robust alternatives to thiols for metal-surface functionalization, offering strong σ-donor character, high thermal stability, and tunable molecular design. Despite advances in NHC surface engineering, the formation of ordere...

Spectral sequences, Massey products and homology of covering spaces

Abstract We revisit the equivariant spectral sequence considered by Papadima–Suciu, and show that all its differentials are computed by higher order Massey products. As a first application, we extend to arbitrary field coefficients results of Pajitnov relating the size of Jordan...

Serum brain-derived neurotrophic factor is associated with diabetic complications and glycemic control in type 2 diabetes: an exploratory analysis of the ADNI cohort

To investigate the association between serum brain-derived neurotrophic factor (BDNF) levels and the clinical profile as well as complications in patients with type 2 diabetes mellitus (T2DM). A total of 185 participants were enrolled, including 35 healthy controls, 111 T2DM pati...

Metallic Ag-BiAg HeterostructuredDendrites AccelerateCarbon–Nitrogen Coupling for Air Plasma-Derived Amino AcidElectrosynthesis

Abstract Electrochemical C–N coupling driven by renewable electricity provides a sustainable strategy for amino acid synthesis, yet achieving high catalytic efficiency still remains challenging. Herein, a metallic Ag-BiAg heterostructured dendritic electrode is developed by a sim...

The Total and Polarized Radio Emission from the Innermost Jets of a High-Redshift Quasar and a Candidate at Parsec-Scale Resolution

High-frequency very long baseline interferometry (VLBI) polarimetry probes synchrotron-emitting plasma closer to the central engines of radio-loud active galactic nuclei (AGNs), but observations above 43 GHz are technically demanding. We present 22-GHz European VLBI Network obser...
