Resistance ofBacillusEndospores to Extreme Terrestrial and Extraterrestrial Environments [PDF]
Microbiology and Molecular Biology Reviews, 2000 SUMMARYEndospores of Bacillus spp., especially Bacillus subtilis, have served as experimental models for exploring the molecular mechanisms underlying the incredible longevity of spores and their resistance to environmental insults. In this review we summarize the molecular laboratory model of spore resistance mechanisms and attempt to use the model as

Machine Learning for Thermodynamic States of Notional Nonideal Energetic Mixtures
Propellants, Explosives, Pyrotechnics, EarlyView.. ABSTRACT Currently, modeling the thermodynamic states in the reaction zone of a detonating energetic mixture entails iteratively solving a set of coupled differential equations that require detailed material property information or models whose empirical parameters must be physically measured.

Journal of Field Robotics, EarlyView.ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

Habitable planetary environments and extraterrestrial life [PDF]
Chinese Science Bulletin, 2016 Arguably one of the most important discoveries in the history of human being is the detection of a planet orbiting a main sequence star beyond the solar system. By the time Science celebrated its 125th anniversary, ~150 exoplanets have been discovered. However, there was no known habitable exoplanet.

Small, EarlyView.This review charts the material evolution of bifunctional electrocatalysts for rechargeable lithium‐gas batteries. It highlights the journey from heteroatom‐doped, metal‐free carbon architectures to precision‐engineered carbon‐supported single‐atom sites. The discussion focuses on mechanistic insights into how these catalysts govern reversible O2, CO2,

Meteoritics &Planetary Science, EarlyView.Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...
