Thermally Induced Creep and Viscoelastic Behavior of Copper Micropillar Arrays

Advanced Science, EarlyView.
Copper micropillar arrays are fabricated by electrodeposition within through‐glass‐via, and their thermally induced time‐dependent deformation is quantified. Nanoindentation creep, EBSD, and TEM reveal a heat‐treatment‐driven transition between grain‐boundary‐mediated deformation and dislocation‐dominated creep, while Kelvin modeling captures ...

Convective Heat Transfer Characteristics of MWNTs Water-based Nanofluid

Zhileng xuebao, 2015
Influence of nanoparticles concentration, Reynolds number and heat flux on the convective heat transfer performance of MWNTs/H2O water-based nanofluid were investigated experimentally. The concentration of nanoparticles was 0.05 g/L, 0.1 g/L, 0.2 g/L and

Multimodal Layer‐Crossing Interrogation of Brain Circuits Enabled by Microfluidic Axialtrodes

Advanced Science, EarlyView.
The study introduces a flexible microfluidic axialtrode that integrates optical, electrical, and chemical modalities within a single polymer fiber. By redistributing electrodes and fluidic channels along the fiber axis via angled cleaving, it enables simultaneous optogenetic stimulation, electrophysiological recording, and drug delivery across brain ...

Evaporation‐Driven Solutal Marangoni Control of Rayleigh–Taylor Instability in Inverted Films

Advanced Science, EarlyView.
Inverted liquid films, like paint on a ceiling, are inherently unstable under gravity. This work shows that selective evaporation in volatile binary mixtures generates solutal Marangoni stresses that either suppress or amplify the Rayleigh Taylor instability.
