Reversible patterning of spherical shells through constrained buckling

Pedro Miguel Nunes Pereira de Almeida Reis, Pierre-Thomas Paul Brun

Recent advances in active soft structures envision the large deformations resulting from mechanical instabilities as routes for functional shape morphing. Numerous such examples exist for filamentary and plate systems. However, examples with double-curved ...

The Chemistry of Neurodegeneration: Kinetic Data and Their Implications

Matej Repic

We collected experimental kinetic rate constants for chemical processes responsible for the development and progress of neurodegeneration, focused on the enzymatic and non-enzymatic degradation of amine neurotransmitters and their reactive and neurotoxic m ...

Modeling, Characterization and Control of a Novel Torsional Shape Memory Alloy (SMA) Actuator

Jamie Paik, Zhenishbek Zhakypov, Jian-Lin Huang

Thermally activated shape memory alloy (SMA) actuators are direct-driven and produce high power density with design versatility. However, beyond their linear actuation in spring forms there is little variety and their application in robotics is limited by ...

Intercellular ultrafast Ca2+ wave in vascular smooth muscle cells: numerical and experimental study

Jean-Jacques Meister, Niccolo Piacentini, Franck Claude Raynaud, Jairo Camilo Quijano Perez

Vascular smooth muscle cells exhibit intercellular Ca2+ waves in response to local mechanical or KCl stimulation. Recently, a new type of intercellular Ca2+ wave was observed in vitro in a linear arrangement of smooth muscle cells. The intercellular wave w ...

Photothermal cellular stimulation in functional bio-polymer interfaces

Diego Ghezzi

Hybrid interfaces between organic semiconductors and living tissues represent a new tool for in-vitro and in-vivo applications, bearing a huge potential, from basic researches to clinical applications. In particular, light sensitive conjugated polymers can ...

2015

The calculation of the steady-state probability density for multidimensional stochastic systems that do not obey detailed balance is a difficult problem. Here we present the analytical derivation of the stationary joint and various marginal probability den ...

Modeling the Channel Charge and Potential in Quasi-Ballistic Nanoscale Double-Gate MOSFETs

Christian Enz, Jean-Michel Sallese, Anurag Mangla

In this paper, we present an analytical semiempirical model of the profile of the channel charge and potential in quasi-ballistic double-gate (DG) MOSFETs. The charge model is based on the premise of separating the charge density in the quasi-ballistic cha ...

Dynamic mechanical analysis for rapid assessment of the time-dependent recovery behavior of shape memory polymers

John Christopher Plummer, Charly David Azra

Thermally activated shape memory polymers (SMPs) recover from a secondary shape induced by mechanical deformation to a primary equilibrium shape when they are heated to their actuation temperature. In certain applications, for example in the biomedical fie ...

A bidirectional shape memory alloy folding actuator

Jamie Paik

This paper presents a low-profile bidirectional folding actuator based on annealed shape memory alloy sheets applicable for meso-and microscale systems. Despite the advantages of shape memory alloys-high strain, silent operation, and mechanical simplicity- ...

2012

On application of heat, shape memory polymers (SMPs) are able to revert to a primary shape from a secondary shape induced by mechanical deformation. It may be desirable to induce shape recovery at controlled rates under quasi-isothermal conditions, e. g. i ...
