Elastomeric 3D‐Printed Microenvironments Enable Nanonewton Force Measurements in Healthy and Diseased Human Pluripotent Stem Cell‐Derived Neuroepithelial Cells

open access: yesAdvanced Materials, EarlyView.
We present elastomeric three‐dimensional (3D) microstructures fabricated via two‐photon polymerization (2PP) and post‐processed through wet etching, for quantifying nanonewton (nN)‐scale forces applied by healthy and diseased neural cells. The mechanically characterized free‐standing beam architectures enable measurement of traction forces of ...

Hitchhiking through life: a review of phoresy in Uropodina mites (Parasitiformes: Mesostigmata)

open access: yesThe European Zoological Journal
Several important papers discussing phoretic dispersal in animals have appeared in recent years, but the nature and evolutionary significance of the phenomenon are still not fully understood.

Organic Options for Striped Cucumber Beetle Management in Cucumbers [PDF]

open access: yes, 2012
Striped cucumber beetles (Acalymma vittata F.) are a serious pest of cucurbits, particularly on organic farms. These pests are the vector and overwintering host for bacterial wilt (Erwinia tracheiphila), which kills plants and can render cucumbers ...

Metastable Polymers for Circular 3D Printing

open access: yesAdvanced Materials, EarlyView.
3D‐printed polymers are usually permanent and hard to recycle. Here, metastable polymers are designed to fall apart on demand. A chemical trigger unzips the printed material back into its original building blocks within minutes at room temperature.

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

open access: yesAdvanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.
