Stability of viscous flow between rotating cylinders. II. Cylinders rotating in opposite directions [PDF]

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1946
In a previous paper (Meksyn 1946; it will be referred to as Part I) the problem of stability of viscous fluid between coaxial cylinders, rotating in the same direction, was solved by expanding the integrals in inverse powers of a large parameter. The question was first considered theoretically and experimentally by Taylor (1923), the problem being ...

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

Advanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

Numerical Study on Flow Field and Abundance Field of a Binary Gas Mixture with Large Mass Number Difference

Journal of Isotopes, 2023
In study of the flow of an isotopic gas mixture in a rotating cylinder, the isotope approximation method is generally introduced to decouple the flow problem of the mixed gas and the component transport problem by considering the small molecular weight ...

Encoding Magnetic Anisotropies in Digital Light Processing 3D Printing

Advanced Functional Materials, EarlyView.
A hybrid magnetic device—combining a coaxial coil within a nested Halbach array—is presented, integrated into a DLP 3D printer to enable spatially resolved magnetic field control. This system enables complex, multimodal responses by programming liquid crystal elastomer resins for magnetic and thermal actuation, and by inducing electrically conductive ...
