Dynamically Adaptive Wrinkle‐Structured Light‐Regulating Films for Energy‐Efficient Buildings

Advanced Functional Materials, EarlyView.
A scalable, moisture‐responsive cellulose nanofibril/polyvinyl alcohol (CNF/PVA)‐glycerol film with switchable wrinkled surfaces for dynamic light regulation is developed. Compared to glass, it achieves tunable light diffusion for daylight harvesting, thermal regulation, and privacy control.

Combined effects of leaks, respiratory system properties and upper airway patency on the performance of home ventilators: a bench study

BMC Pulmonary Medicine, 2017
Background Combined effects of leaks, mechanical property of respiratory system and upper airway (UA) patency on patient-ventilator synchrony (PVA) and the level of clinically “tolerable” leaks are not well established in home ventilators.

A Scalable, Durable, Fire‐Safe All‐Day Passive Radiative Cooling Coating for Sustainable Buildings

Advanced Functional Materials, EarlyView.
This study reports a scalable, durable coating that combines a fire‑retardant copolymer adhesive, hollow glass microspheres, and boron oxide to achieve passive radiative cooling with over 94% solar reflectance and >95% mid‑infrared emissivity. The coating maintains performance after UV and rain exposure and exhibits UL‑94 V‑0 fire resistance, enabling ...

State-of-the-Art Sensor Technology in Spain: Invasive and Non-Invasive Techniques for Monitoring Respiratory Variables

Sensors, 2010
The interest in measuring physiological parameters (especially arterial blood gases) has grown progressively in parallel to the development of new technologies. Physiological parameters were first measured invasively and at discrete time points; however,

Cortical Response to Acute Implantation of the Utah Optrode Array in Macaque Cortex

Advanced Healthcare Materials, EarlyView.
Delivering light deep into the brain over a large volume while causing minimal tissue damage is a major challenge for non‐human primate optogenetics. This study evaluates Utah Optrode Array designs in vivo, revealing how changes in shank geometry, surface texture, and insertion parameters minimize acute damage—offering a path toward high‐precision ...
