A possible impact lull in the middle of the Eratosthenian period suggested by the Chang’e-5 and 6 missions

Astronomy & Astrophysics
Context. It was generally believed that lunar impact flux over the past 3.5 billion years has been almost constant. However, there are still considerable age gaps, causing the evolution of impact flux to remain elusive.

Imide Substitution Drives the Supramolecular Assembly of Perylene Diimide Into Laterally Modulated Metallic/Semiconducting Molecular Patterns

Advanced Materials Interfaces, EarlyView.
Imide substitution with bulky 2,6‐isopropylphenyl groups induces perylene diimide to self‐assemble on Ag(111) into a monolayer with two coexisting adsorption heights. Molecules closer to the substrate gain metallic character due to charge transfer from the metal, while farther ones remain decoupled and semiconducting.

Tailoring Iron Nanostructures on MoS2: The Pivotal Role of Sulfur Vacancies in Growth Morphology and Charge Transfer

Advanced Materials Interfaces, EarlyView.
The deposition of Iron on pristine MoS2/Au(111) monolayers produces nanoparticles that donate charge to the support, generating Fe+2‐interfacial species. On the contrary, on defect‐engineered MoS2, sulfur vacancies trap sub‐nanometric Fe clusters and host two excess electrons that redistribute locally, suppressing Fe oxidation without formal Mo ...

Advanced MXene‐Based Multifunctional Nanoarchitecture Materials Engineered for Adsorptive Cleanup of Hazardous Radioactive Pollutants: A Comprehensive Critical Review

Advanced Materials Interfaces, EarlyView.
This work critically reviews MXenes as highly effective multifunctional nanomaterials for the adsorption of radio‐contaminants, demonstrating a remarkable adsorption capacity of up to 1376.75 mg/g and cyclic stability of 2–8 cycles, with complexation, electrostatic interactions, and the numerical strength of MXene active sites playing a key operational

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

3D‐Printed Dual‐Doped Ag2Se‐Based Thermoelectric Films With Enhanced Thermal Stability

Advanced Materials Technologies, EarlyView.
Sb–Se dual doping enhances the thermal stability of Ag2Se‐based thermoelectric systems. The compositionally tuned nano‐ink is printed into flexible films by direct ink writing (DIW), retaining improved thermoelectric properties after annealing up to 400°C.
