Herein, the fabrication of light-sensitive high-aspect ratio surfaces with switchable topography using melt-electrowriting shape-memory polymers and deposition light-to-heat converting black ink on it by dip coating is reported on. The lamellae exposed to low temperatures are hard cannot be deformed water droplets. temperature reached upon illumination close melting point soft segment polyureth...

We present an experiment designed to study magnetohydrodynamic effects in free surface channel flow. The wide aspect ratio channel (the width to height ratio is about 15) is completely enclosed in an inert atmosphere to prevent oxidization of the liquid metal. A custom-designed pump reduces entrainment of oxygen, which was found to be a problem with standard centrifugal and gear pumps. Laser Do...

In this paper, a comprehensive study on the performance of parallel plate and rectangular micro channel counter flow heat exchangers is presented. The geometrical parameters of the two configurations are optimized for a given heat transfer rate, effectiveness and pressure drop. In case of rectangular micro channel counter flow heat exchanger, a reduced order model is developed first in which re...

Front Cover: In article number 2000754, Susan M. Kelleher and co-workers outline an accessible scalable method for polyethylene glycol (PEG)-tapered nanopillar array production. Photopolymerisation of acrylateterminated polypropylene (PPG) PEG monomeric/photoinitiator cocktails is utilised to cast high fidelity replicas silicon arrays. this way, rapid prototyping polymeric nanostructured surfac...

Continuum diffusion models are often used to represent the collective motion of cell populations. Most previous studies have simply used linear diffusion to represent collective cell spreading, while others found that degenerate nonlinear diffusion provides a better match to experimental cell density profiles. In the cell modeling literature there is no guidance available with regard to which a...

Although local interactions involving orientation and spatial frequency are well understood, less is known about spatial interactions involving higher level pattern features. We examined interactive coding of aspect ratio, a prevalent two-dimensional feature. We measured perception of two simultaneously flashed ellipses by randomly post-cueing one of them and having observers indicate its aspec...
