Journal ArticleDOI
A self-propelled biohybrid swimmer at low Reynolds number
TL;DR: This work reports a microscale, biohybrid swimmer enabled by a unique fabrication process and a supporting slender-body hydrodynamics model and demonstrates a two-tailed swimmer swimming at 81 μm s(-1).
Journal ArticleDOI
Plastic deformation recovery in freestanding nanocrystalline aluminum and gold thin films.
TL;DR: It is shown experimentally that plastically deformed nanocrystalline aluminum and gold films with grain sizes of 65 nanometers and 50 nanometers recovered a substantial fraction of plastic strain after unloading, suggesting that strain recovery might be characteristic of other metals with similar grain sizes and crystalline packing.
Journal ArticleDOI
Drosophila neurons actively regulate axonal tension in vivo.
TL;DR: High-resolution micromechanical force sensors are used to study the mechanical response of motor neurons in live Drosophila embryos and suggest that mechanical tension may also strongly influence neuronal behavior in vivo.
Journal ArticleDOI
In situ TEM study of microplasticity and Bauschinger effect in nanocrystalline metals
Jagannathan Rajagopalan,Christian Rentenberger,H. Peter Karnthaler,Gerhard Dehm,M. Taher A. Saif +4 more
TL;DR: In this article, the effect of microstructural heterogeneity on the deformation behavior of nanocrystalline metal films was studied in situ transmission electron microscopy straining experiments with concurrent macroscopic stress-strain measurements.
Journal ArticleDOI
A single transmitter multi-receiver (STMR) PZT array for guided ultrasonic wave based structural health monitoring of large isotropic plate structures
TL;DR: In this article, a new compact sensor configuration comprising a single transmitter and multi-receivers (STMR) is presented for the in situ structural health monitoring (SHM) of large plate-like isotropic structures.
