Assessment of Crystalline Materials for Solid State Lighting Applications: Beyond the Rare Earth Elements

Crystals, 2020
In everyday life, we are continually exposed to different lighting systems, from the home interior to car lights and from public lighting to displays. The basic emission principles on which they are based range from the old incandescent lamps to the well-

Localized Hydrogen Release Driven by Mg–Pd Microgalvanic Cells from 3D‐Printed Microneedles Reverses Redox Homeostasis for Psoriasis Treatment

Advanced Science, EarlyView.
A 3D printing microneedle (MP‐MN), loading magnesium‐based micro‐galvanic cells (MP), is designed for improving psoriasis. H2 generated from MP‐MN scavenges ROS and •OH, actives NRF2‐KEAP1 pathway, and decreases inflammation, thereby effectively restoring the oxidative stress homeostasis of psoriatic skin and suppressing the excessive proliferation of ...

Extending El Sayed's Rule by 1(n,π*)–3(n,π*) Rotation via Intramolecular Secondary Interaction Enables Room‐Temperature Circularly Polarized Phosphorescence in Solution

Angewandte Chemie, EarlyView.
Weak but skilled: Our results highlight the crucial role of intramolecular secondary interactions to induce an efficient ISC between formally identical 1(n,π*) and 3(n,π*) states in chiral thionated phthalimide derivatives. This unprecedented type of inter‐system crossing (ISC) extends the usual thinking of the El‐Sayed principle and enables the ...

Tuning Acetal and Disulfide Network Dynamics in Dynamic Diamine‐Cured Partially Bio‐Epoxy Networks

Journal of Applied Polymer Science, EarlyView.
This study investigates the development of high‐performance, sustainable vitrimers by balancing partially bio‐based epoxy resins with dynamic hardener chemistry. The research identifies how resin architecture and specific curing agents influence thermal stability, bond‐exchange kinetics, and environmental durability.

Luminescent boron carbon oxynitride phosphors: a cost-efficient strategy to boost solar cell spectral responsiveness

Materials Research Express
The incorporation of a Luminescent down-shifting (LDS) layer has emerged as a compelling approach for augmenting the light absorption sensitivity and power conversion efficiency of solar cells, particularly in the short-wavelength light spectrum. In this

Expanding Metabolic Online Monitoring Capabilities in 96‐Deepwell Microtiter Plates by Combining Optoelectronic O2 and CO2 Sensors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT To increase the information content in early stages of bioprocess development, various technologies have been introduced for monitoring cultivations in microtiter plates (MTPs). Besides spectroscopical measurements, like in the BioLector technology, optical measurements with luminescent sensors, placed directly in the cultivation medium ...
