Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Bronchoscopy Robot with Enhanced Flexibility and Stability via Multi‐Segment Variable Stiffness Catheter

Advanced Intelligent Systems, EarlyView.
This work presents a magnetic bronchoscopy robot with a novel multi‐segment variable stiffness catheter. This catheter can not only move flexibly in the narrow bronchi but also harden according to the need to provide support. Combined with remote wireless magnetic field drive, it provides a more precise and effective solution for biopsy of deep lung ...

Laminar viscous dissipation in rectangular ducts [PDF]

International Communications in Heat and Mass Transfer, 1998
Abstract In this paper, a theoretical study is conducted, calculating the temperature distribution in the cross-section of a rectangular duct, under the conditions of newtonian and incompressible fluid, fully developed laminar flow and steady-state regime.

The role of the viscous dissipation in microchannels [PDF]

, 2007
Many experimental works appeared in the last decade in the open literature dealing with forced convection through microchannels. These experimental results evidenced that for channels having a hydraulic diameter less than 1 mm the conventional theory can no longer be considered as able to predict pressure drop and convective heat transfer coefficients.

Influence of viscous dissipation on Bénard convection

Journal of Fluid Mechanics, 1974
The approximations implicit in Bénard convection have been modified to include viscous dissipation. It is shown that both the influence of an adiabatic temperature gradient and of viscous dissipation are governed by the same dimensionless parameter Di = αgh/cp. Numerical calculations of finite amplitude convection are given for finite values of Di.

Viscous dissipation in die flows

AIChE Journal, 1974
AbstractThe flow of polymer melts in cylindrical, annular, and slit dies has been examined. Large temperature rises at the outer surface of the extrudate were measured with an infrared pyrometer. Calculations show that severe radial temperature gradients exist in these flow geometries under conditions similar to those encontered in polymer processing ...
