Yutu-2 Radar Observations at the Chang’E-4 Landing Site: The Shallow Geological Structure and Its Dielectric Properties

open access: yesUniverse, 2023
China has successfully carried out five lunar exploration missions since 2007. These missions indicate that China has successfully implemented a three-step lunar exploration program of “orbiting, landing, and returning”. Among them, the Lunar Penetrating

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

open access: yesAdvanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Lunar‐Based Photothermal CO2 Reduction Strategy: Self‐Evolving Transient Active Interface and Band Engineering

open access: yesAdvanced Science, EarlyView.
A self‐evolving Pd/Ov‐FeTiO3 photothermal catalyst, inspired by lunar soil, enables efficient extraterrestrial CO2 conversion. The formation of transient active interfaces and oxygen vacancies extends light absorption to the infrared range and optimizes electron transfer.

Setting Diverging Colors for a Large-Scale Hypsometric Lunar Map Based on Entropy

open access: yesEntropy, 2015
A hypsometric map is a type of map used to represent topographic characteristics by filling different map areas with diverging colors. The setting of appropriate diverging colors is essential for the map to reveal topographic details.

Verification and Mitigation of Proton‐Induced Non‐Ionizing Damage in Perovskite Solar Cells for Space Applications

open access: yesAdvanced Energy Materials, EarlyView.
Metal‐halide perovskite solar cells offer high‐efficiency power for orbital missions but suffer from permanent proton‐induced degradation. This work identifies non‐ionizing energy loss (NIEL) as the primary driver of irreversible failure, inducing atomic displacements and microcracks in the high‐fluence regime. Through energy‐tuned mapping and scalable

The Strategic Role of Sustainability Certifications: A Multi‐Theoretical Framework and Comparative Analysis in the Global Wine Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Sustainability certifications are increasingly embedded in the governance and competitiveness of the wine sector, yet their strategic role remains under‐theorised. This study conceptualises certifications as multidimensional strategic mechanisms and conducts a comparative analysis of 50 schemes used in the global wine industry.
