Multistage, Self‐Sensing Artificial Muscles With Coordination From Liquid Crystal Elastomer‐Graphene Composite Fibers

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by skeletal muscles’ precision and endurance, CoilLCE integrates a self‐sensing liquid crystal elastomer/graphene artificial muscle with an embedded Joule‐heating copper coil, enabling closed‐loop multistage actuation with programmable intermediate states (strain accuracy of 2%), and antagonistic coordination (32% total strain). These features

Immersed Cooling of Electronics

open access: yes, 2016
This master thesis is supported by Ericsson to conduct research on immersed liquid cooling of electronics. By this technology, the liquid will be in direct contact with the electronics. The research begins with investigations in industrial background, literature review and theory in heat transfer.

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

open access: yesAdvanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

NUMERICAL SIMULATION OF FISH FREEZING PROCESS BY IMMERSION COOLING AND COLD AIR BLASTING METHODS

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2008
A three dimensional simulation of cooling and freezing process of fish as a complex geometry is presented. The 3d geometry of the fish was produced by digitizing and the thermo-physical properties of the fish were considered as functions of temperature ...

Anisotropic Phonon Dynamics and Directional Transport in Actinide Van der Waals Semiconductor Uranium Triselenide

open access: yesAdvanced Functional Materials, EarlyView.
USe3 is introduced as an actinide van der Waals semiconductor that mirrors the quasi‐one‐dimensional physics of transition‐metal trichalcogenides. Polarization‐resolved Raman spectroscopy on exfoliated flakes maps strong in‐plane phonon anisotropy and strain‐tunable mode shifts.
