Dynamic modelling of an intermittent slider–crank mechanism

, 2014
[[abstract]]This paper investigates kinematic and dynamic analyses of a novel intermittent slider–crank mechanism, which consists of four parts: a crank, a connecting rod associated with a pneumatic cylinder, a slider and two stops at both ends of a ...

From muscle fibres to muscle gears: how dynamic fascicle orientation and shape change impact skeletal muscle function

Biological Reviews, EarlyView.
ABSTRACT Skeletal muscle architectural design strongly affects force‐generating capacity and excursion range, and its functional importance to animal and human movement is well founded. Traditionally, this ‘structure–function relation’ has been inferred from architecture measurements with muscles at rest (from anatomical dissections or medical imaging ...

Interface‐Engineered Li–Ni–O/Ni Heterostructures With Tunable Vacancies on Biochar Enable Biomass‐to‐Hydrogen Conversion

Carbon Energy, EarlyView.
This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

Multi‐Scale Investigation of Supramolecular Organogels Assembled From Pt(II)‐Salphen Complexes

Chemistry – A European Journal, EarlyView.
A family of Pt(II)‐salphen complexes with long alkyl chains is investigated as low‐molecular‐weight organogelators. Multi‐scale characterization of their supramolecular gels reveals how the chain length, Pt‐Pt interactions, and π–π stacking direct self‐assembly and tune gel mechanics.
