A Framework for Quantifying the Degeneracies of Exoplanet Interior Compositions

open access: yes, 2010
Several transiting super-Earths are expected to be discovered in the coming few years. While tools to model the interior structure of transiting planets exist, inferences about the composition are fraught with ambiguities.

A Printed Zinc‐Ion Microbattery with Extended Shelf Life and Durability for Energy Autonomous Sensors

open access: yesAdvanced Functional Materials, EarlyView.
We present a fully printed aqueous zinc‐ion microbattery (ZnIB) enabled by graphene‐decorated zinc anode and printed MnO@NC cathode using sustainable aqueous‐based ink formulations. The printed 3D electrodes ensure uniform zinc deposition, low overpotential, and long‐term stability.

Research of the Tooth Surface Equation and Sliding Characteristic of Internal Cycloid Planetary Transmission with Point Contact

open access: yesJixie chuandong, 2015
A new gear pair of cycloidal planetary transmission with point contact is proposed. The equations of tubular meshing tooth surfaces and contact locus of internal cycloidal planetary transmission are derived respectively.

A Decrease in Slope Angles on Insolated Martian Slopes: Ground-based Experiments

open access: yesThe Planetary Science Journal
Dry granular flow on Martian slopes can benefit from subsoil Knudsen compressors induced by thermal creep gas flow. The required temperature gradient for this natural compressor can be set by insolation.

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Geologic History of the Amundsen Crater Region Near the Lunar South Pole: Basis for Future Exploration

open access: yesThe Planetary Science Journal
We provide the first detailed 1:100,000 scale geomorphologic map of the ∼100 km Amundsen crater region, which is of high scientific relevance for future exploration, e.g., NASA’s VIPER mission, the Artemis program, and the Chinese International Lunar ...

Performance Constraints of All‐Perovskite Tandem Solar Cells in Low‐Intensity, Low‐Temperature Environments

open access: yesAdvanced Materials, EarlyView.
All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.
