Versatile Pneumatic Twisted Coiled Actuators Enabled by Fiber‐Polymer Composite Fabrication

Advanced Functional Materials, EarlyView.
This work reports composite Pneumatic Twisted Coiled Actuators with embedded Kevlar fibers that convert pneumatic or hydraulic pressure into powerful linear motion. A novel precise manufacturing technique is used to systematically explore how design variables influence actuator mechanics and dynamics.

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Assessment of Root Canal Filling Capacity and Quality of the Root Canal Pastes

Acta Stomatologica Croatica
Background: The complex anatomy of root canals in primary teeth makes root canal treatment and canal filling difficult. Root canal filling materials should meet the basic requirements for hermetic filling in terms of their physicochemical properties ...

Resilon: A Comprehensive Literature Review

Journal of Dental Research, Dental Clinics, Dental Prospects, 2013
Bonding to dentin is a promising property, which can prevent leakage and improve the sealing ability of endodontic filling materials. Resilon was developed and recommended initially because the existing root canal filling materials did not bond to root

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...
