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...

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...

The connectedness percolation threshold (η(c)) and critical coordination number (Z(c)) of systems of penetrable spherocylinders characterized by a length polydispersity are studied by way of Monte Carlo simulations for several aspect ratio distributions. We find that (i) η(c) is a nearly universal function of the weight-averaged aspect ratio, with an approximate inverse dependence that extends ...

research in convective heat transfer using suspensions of nanometer-sized solid particles in base liquids started only over the past decade. recent investigations on nanofluid, as such suspensions are often called, indicate that the suspended nanoparticles remarkably change the transport properties and heat transfer characteristics of the suspension. bending walls can also improve heat transfer...
