The Hidden Dangers of Counterfeit and Replica-Like Endodontic Files: A Scoping Review of Current Evidence. [PDF]
ABSTRACT This scoping review mapped and critically appraised laboratory evidence on counterfeit and replica‐like nickel–titanium endodontic files, evaluating design, metallurgical composition, surface finishing, and mechanical performance to clarify clinical and regulatory implications.

Strength analysis of helical buckling tubing using spring theory [PDF]
With the constraint of the wellbore, tubing has possibility to conduct spiral plastic deformation if axial compression load is great enough. The residual stress from the plastic deformation of tubing will eventually influence the effective stress, thus strength safety.

MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Cuttlebone‐inspired metamaterials exploit a septum‐wall architecture to achieve excellent mechanical and functional properties. This review classifies existing designs into direct biomimetic, honeycomb‐type, and strut‐type architectures, summarizes governing design principles, and presents a decoupled design framework for interpreting multiphysical ...

Emergence of Escherichia coli critically buckled motile helices under stress [PDF]
Significance We have discovered an emergent mechanism by which Escherichia coli can escape high-stress regions, such as near-lethal concentrations of antibiotics, by forming long motile helical filaments that are poized at the critical shear buckling point: 2 π
