Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

In vivo dehydration of disposable (Acuvue) contact lenses

, 1990
The in vivo dehydration of the Acuvue disposable contact lens was measured in six subjects using a contact lens refractometer. On average, the lenses dehydrated 6.2 +/- 1.9% after 20 min and 10.2 +/- 3.9% after 6 h of wear.

Dehydration of hydrogel lenses during overnight wear [PDF]

, 1987
We studied the extent of dehydration of hydrogel lenses during overnight wear. Seven subjects used a hand refractometer to measure the water content of five different lenses (Hydron zero-6 (nominal water content 38.6%), -0.50 D; Snoflex 50 (52.5%), -0.50

Integrated Multiband Smart Windows From UV to LWIR Based on Molecularly Engineered Thermochromic Hydrogels

Advanced Functional Materials, EarlyView.
A multiband smart window integrating a thermochromic poly (EEEA‐co‐NIPAM) hydrogel with functional layers, enabling dynamic VIS‐NIR solar modulation alongside UV shielding and low LWIR emissivity. The polymer network forms hydrogen‐bonding interactions, promoting chain collapse above a reduced lower critical solution temperature, and accelerating the ...
