Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate
Advanced Science, EarlyView.We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

International Scholastic Journal of Science, 2007 The diameter of craters formed by spheres of varying mass dropped into sand at low speed was studied. The relationship between the diameter of the crater formed and the kinetic energy of the projectile at impact was found to be of the same general form ...

Crater Observing Bioinspired Rolling Articulator (COBRA)
Advanced Intelligent Systems, EarlyView.Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

The Effect of Antecedent Topography on Complex Crater Formation
Geophysical Research LettersImpact craters that form on every planetary body provide a record of planetary surface evolution. On heavily cratered surfaces, new craters that form often overlap antecedent craters, but it is unknown how the presence of antecedent craters alters impact

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Coronary perforations are a dreaded complication for any interventional cardiologist. The treatment of this complication is exceptionally difficult when it occurs in a coronary bifurcation. While a conservative approach or a balloon occlusion might be sufficient in some cases, additional treatment is sometimes necessary.
