Internal dynamics around static-deformation FEM states [PDF]

open access: yes, 2005
Constant velocity or constant force FEM solutions are static-deformation states, where the elastic deformation is stationary. These are the typical operation conditions.

A Photonastic Prototissue Capable of Photo‐Mechano‐Chemical Transduction

open access: yesAdvanced Materials, EarlyView.
Mimicking energy transduction in prototissue assemblies remains a challenge of bottom‐up synthetic biology. In this work, prototissues integrating protocells with photothermal gold nanoparticle proto‐organelles and a thermoresponsive polymeric proto‐cortex are developed.

Minimization of Energy Functionals via FEM: Implementation of hp-FEM

open access: yes
Many problems in science and engineering can be rigorously recast into minimizing a suitable energy functional. We have been developing efficient and flexible solution strategies to tackle various minimization problems by employing finite element discretization with P1 triangular elements [1,2].

Multi‐Mode Mechanochromic Responses from Cholesteric Liquid Crystal Elastomer Tubes of Uniform Sheath

open access: yesAdvanced Materials, EarlyView.
The structural‐colored tube is created from cholesteric liquid crystal elastomers, exhibiting uniform color changes with high strain sensitivity upon extension and inflation. The color change occurs across multiple mechanochromic modes, highlighting the influence of molecular anisotropy and tubular geometry on strain sensitivity.

Dual‐Selective Terahertz‐Nanodisc Metasurfaces for Exploring Neurotransmitter Dynamics beyond Spectral Limitations

open access: yesAdvanced Materials, EarlyView.
Observation and detection of neurotransmitter dynamics in aqueous system has been hurdle for analytical fields due to its weak and reversible nature. A terahertz‐nanodisc metasurface which implements comprehensive detection over conformational change and selective sensing is introduced. Utilizing the THz regime photonics and biomimetic environment with

Transient Non-linear Thermal FEM Simulation of Smart Power Switches and Verification by Measurements [PDF]

open access: yes, 2007
Thermal FEM (Finite Element Method) simulations can be used to predict the thermal behavior of power semiconductors in application. Most power semiconductors are made of silicon. Silicon thermal material properties are significantly temperature dependent.
