A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring
Advanced Science, EarlyView.Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Gas-Rich Companions of Isolated Galaxies [PDF]
, 1999 We have used the VLA to search for gaseous remnants of the galaxy formation process around six extremely isolated galaxies. We found two distinct HI clouds around each of two galaxies in our sample (UGC 9762 & UGC 11124).

Collision‐induced Galaxy Formation
The Astrophysical Journal, 1998 We present a semi-analytical model in which galaxy collisions and strong tidal interactions, both in the field and during the collapse phase of groups and clusters help determine galaxy morphology. From a semi-analytical analysis based on simulation results of tidal collisions (Aguilar & White 1985), we propose simple rules for energy exchanges ...

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation
Advanced Science, EarlyView.This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Approximations to galaxy star formation rate histories: properties and uses of two examples
, 2018 Galaxies evolve via a complex interaction of numerous different physical processes, scales and components. In spite of this, overall trends often appear.

Advanced Science, EarlyView.A microneedle spoilage sensor for packaged food products is presented. The sensor is composed entirely of food‐derived agents, integrated together using a novel material processing approach. This resultant platform nondestructively reports spoilage state in real‐time through a colorimetric output.
