Angewandte Chemie, EarlyView.Porous polymer monoliths embedded with sensitizer–annihilator dye pairs enable efficient solid‐state visible‐to‐ultraviolet triplet–triplet annihilation‐based photon upconversion under low‐intensity blue and green light. Their co‐continuous porous architectures balance chromophore interactions with substrate accessibility, providing robust and tunable ...

Highly Entangled Bottlebrush Polymer Networks
Advanced Materials, EarlyView.Bottlebrush polymers are difficult to entangle, enabling ultrasoft yet brittle networks. We report highly entangled bottlebrush elastomers that remain ultrasoft (∼1 kPa) yet stretch to ∼1800% and exhibit exceptional fatigue resistance. Their intrinsic fatigue strength—fatigue threshold normalized by modulus—surpasses that of highly entangled linear ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Advanced Materials Interfaces, EarlyView.Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

A Hyperspectral Camera in the UVA Band [PDF]
IEEE Transactions on Instrumentation and Measurement, 2015 We present a hyperspectral camera based on a Fabry–Perot interferometer designed to work in the UVA range (315–400 nm). The measured hypercube contains about $400 \times 400$ pixels, for a total of 160 000 spectra. Each spectrum has a spectral resolution of about 5 nm at the wavelength of 315 nm. Spatial and spectral discrimination capability has

Advanced Materials Technologies, EarlyView.A fully organic UV threshold dosimeter is developed by exploiting the oxygen‐sensitive room‐temperature phosphorescence of a purely organic emitter in a polymer matrix. Upon reaching a specific cumulative UV dose, photochemical oxygen depletion triggers a sharp, high‐contrast emission.
