The Impact of Lipid Digestion on the Dynamic and Structural Properties of Micelles

This work uses molecular dynamics simulations and small‐angle neutron scattering to study the self‐assembly and degradation of micelles formed by the short‐chain phosphocholine lipid, 1,2‐dihexanoyl‐sn‐glycero‐3‐phosphocholine. The internal structure of the micelles formed before, during and after degradation by the PLA2 enzyme is detailed and changes...

Robust Anode‐Supported Cells with Fast Oxygen Release Channels for Efficient and Stable CO2 Electrolysis at Ultrahigh Current Densities

Novel anode‐supported solid oxide electrolysis cells demonstrate high and stable CO2 electrolysis performance at a record high current density of 2.5 A cm−2, achieved by the dendritic channel structure of anodes, which enables the formation of robust cell structure and fast oxygen release pathway to cope with the anode delamination in conventional cathode‐supported...

Water‐Induced Formation of Ni2P–Ni12P5 Interfaces with Superior Electrocatalytic Activity toward Hydrogen Evolution Reaction

The formation of interfaces between Ni2P and Ni12P5 is, for the first time, demonstrated by direct phosphorization of nickel foams (NF) with the assistance of water. The abundant interfaces endow Ni2P–Ni12P5/NF with excellent electrocatalytic hydrogen evolution reaction (HER) activity in alkaline condition, with overpotentials of 76 and 147 mV at the...

Heterostructure Engineering of Core‐Shelled Sb@Sb2O3 Encapsulated in 3D N‐Doped Carbon Hollow‐Spheres for Superior Sodium/Potassium Storage

The core‐shelled Sb@Sb2O3 heterostructure encapsulated in 3D N‐doped carbon hollow‐spheres are fabricated by spray‐drying combined with heat treatment. The core‐shelled heterostructures possess a mass of heterointerfaces, which can promote the rapid Na+/K+ transfer and enhance the Na/K‐storage capacity, while the combination of core‐shelled heterostructure...

A Multifunctional Nanovaccine based on L‐Arginine‐Loaded Black Mesoporous Titania: Ultrasound‐Triggered Synergistic Cancer Sonodynamic Therapy/Gas Therapy/Immunotherapy with Remarkably Enhanced Efficacy

An ultrasound (US)‐triggered “nanovaccine” like system based on L‐arginine (LA)‐loaded black mesoporous titania nanocomposites (BMT@LA NCs) is rationally designed. The obtained BMT@LA NCs can effectively inhibit the primary tumors upon US irradiation and trigger the immune reaction, thus behave as the “nanovaccine” like features. Additionally, combined...

Low Band Gap Benzoxazole‐Linked Covalent Organic Frameworks for Photo‐Enhanced Targeted Uranium Recovery

Excellent photocatalytic activity, photothermal and photoelectric effects make Tp‐DBD produce biotoxic ROS, have good anti‐biofouling activity, and increase the adsorption rate and affinity of uranium binding sites, thereby improving the recovery capacity of uranium. Abstract The inherent features of covalent organic frameworks (COFs) make...

Triggered Dimerization and Trimerization of DNA Tetrahedra for Multiplexed miRNA Detection and Imaging of Cancer Cells

DNA tetrahedra act as building modules for the reversible formation and dissociation of dimer and trimer nanostructures using G‐quadruplex and T‐A•T triplex as stimuli‐responsive bridging units. Also, microRNA (miRNA)‐guided formation of DNA tetrahedra dimers or trimer is applied for the multiplexed fluorescence analysis of miRNAs and the optical imaging...

Rapid Controllable Synthesis of Atomically Dispersed Co on Carbon under High Voltage within One Minute

Atomically dispersed Co‐N sites on carbon (Co/N‐C) are successfully fabricated within 1 min under high voltage. With continuous or intermittent high voltage, the morphological structure of Co/N‐C is controlled as ultrathin nanosheets and hollow nanospheres, respectively. The latter catalyst shows high performance in the oxygen reduction reaction. This...

Engineering the Near‐Surface of PtRu3 Nanoparticles to Improve Hydrogen Oxidation Activity in Alkaline Electrolyte

PtRu3/PC nanocatalysts with the same bulk composition and a different near‐surface atomic composition have been successfully synthesized via a controlled thermal treatment method. The Ru‐increased nanocatalyst with the strongest electronic effect and oxophilic effect exhibits up to 38.8‐fold and 9.2‐fold HOR improvement in mass activity and exchange...

Study of the Growth Mechanism of Solution‐Synthesized Symmetric Tellurium Nanoflakes at Atomic Resolution

This article reveals the nature of moiré fringes appearing at the symmetric axis region of quasi‐2D Te nanoflakes with different shapes, and a possible growth mechanism is proposed that can describe the morphology evolution of these symmetric nanoflakes from “V” shape, “heart” shape to “paper airplane” shape. This work would enrich related applications...
