Where Precursor Loading Stops Making a Difference: Resolving an Operational Infiltration Limit for Nanoparticle Synthesis Using Dual Quantification of Reverse Micelle Nanoreactors

Advanced Materials Interfaces, EarlyView.
A dual characterization strategy combining nanomechanical and mass measurements resolves a common operational loading threshold in reverse micelle nanoreactors. This transferable framework provides a rational strategy for optimizing precursor loading and nanoparticle synthesis, across template‐mediated fabrication systems.

Effect of Nitrogen Doping on the Proton‐Irradiation Stability of Carbon Nanowalls

Advanced Materials Interfaces, EarlyView.
Proton irradiation effects in carbon nanowalls are systematically compared with nitrogen‐doped counterparts over a wide fluence range. While both systems maintain structural integrity, nitrogen incorporation alters the functional response under irradiation.

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.

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 ...

General circulation modelling of close-in extrasolar giant planets [PDF]

, 2011
PhDA large fraction of the extrasolar planets detected so far are giant planets that have such short orbital periods (a few days) that they are thought to be tidally-synchronised with the host star. Such orbits lead to permanent day/night sides on the

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.

Calibration of the angular momenta of the minor planets in the solar system

, 2019
Aims. We aim to determine the relative angle between the total angular momentum of the minor planets and that of the Sun-planets system, and to improve the orientation of the invariable plane of the solar system. Methods. By utilizing physical parameters
