Advanced Functional Materials, EarlyView.A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

Advanced Healthcare Materials, EarlyView.TOC represents the synthesis of theory‐guided novel near‐infrared (NIR) light‐absorbing organic photosensitizers (OPS) enabling redox‐induced tumor phototherapy and single‐cell organelle tracking. ABSTRACT The design of organic photosensitizers that operate efficiently in the near‐infrared (NIR) region remains challenging due to the need to balance ...

IntersectionR-torsion and analytic torsion for pseudomanifolds
Mathematische Zeitschrift, 1987 For a closed Riemannian manifold the Reidemeister torsion equals the analytic torsion T [see \textit{J. Cheeger}, Ann. Math., II. Ser. 109, 259- 322 (1979; Zbl 0412.58026); \textit{W. Müller}, Adv. Math. 28, 233-305 (1978; Zbl 0395.57011)]. We construct a finer invariant, the intersection R-torsion \(I\tau\) for pseudomanifolds.

Advanced Healthcare Materials, EarlyView.A microfluidic device with magnetic microposts was used to assess platelet mechanobiology. The oscillatory actuation of posts with embedded iron particles was dampened by the dynamic stiffening of the platelet‐rich plugs. This stiffening process increased with applied load, but inhibiting platelet activation (ASA) or myosin contractility (blebbistatin)

Analytic torsion forms and torsion-signature
, 1998 Local families index theorems have revealed a rich context in which to place nonlocal spectral invariants such as the eta invariant and analytic torsion. The index theorem for families of Dirac operators on manifolds with boundary involves the eta invariant as the degree-zero component of an ``eta differential form'' on the base.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...
