Numerical simulations of dynamic rock damage under laser-induced shock waves
Meitian dizhi yu kantanObjectiveTraditional laser thermal rock breaking technologies suffer from high energy consumption and a limited damage depth. To overcome these challenges, this study proposed a novel mechanical rock breaking method based on high-pressure plasma shock ...

Advanced Science, EarlyView.Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

Advanced Science, EarlyView.Deterministic crypt fission is achieved in intestinal organoids using photopatternable hydrogels with spatiotemporal control. Daughter‐crypt symmetry is shown to depend on parent‐crypt geometry and epithelial curvature, while myosin‐dependent mechanosensing links tissue shape to regenerative outcomes.

Modelling rock slope behaviour and evolution with reference to Northern Spain and Southern Jordan [PDF]
, 2004 The geomorphological behaviour of steep jointed rock slopes has been studied using distinct element computer models. In order to model steep slopes effectively, methodologies need to be combined from the studies of environmental modellers ...

Responsive Open Microfluidic Logic for Mechanical Computing
Advanced Science, EarlyView.Coupling elasticity with capillarity transforms mechanical compression into binary fluidic states, enabling deterministic logic in open microfluidic circuits. This work demonstrates that computation can emerge from interactions between mechanic and fluidic domains, establishing a general strategy for embedding information processing directly within ...

High Upper Critical Field and Type II Superconductivity in Epitaxial Cubic W2N Thin Films
Advanced Science, EarlyView.Superconducting thin films of stoichiometric W2N demonstrate a high upper critical field (Hc2) of ∼ 8.5 T, uncommon among binary transition metal nitrides. This robust superconducting response under high magnetic fields highlights the technological relevance of W2N for superconducting applications, e.g., integrated quantum and cryogenic electronics ...
