Bright LaF3:Eu@Ir Phosphors Combining Two‐Photon Excitation, d → f Energy Transfer and Tunable Time‐Gated Chromaticity for Multicolor Cell Imaging

open access: yesAdvanced Optical Materials, EarlyView.
The surface functionalization of Eu‐doped LaF3 particles with a two‐photon absorbing IrIII complex results in the formation of ultrabright Eu:LaF3 phosphors, which exhibit a combination of short‐lived IrIII and long‐lived EuIII‐sensitized emissions. These Ir/Eu hybrids are effectively internalized by HEK‐293 cells without causing toxic effects, thereby

The X-ray Outburst of H1743-322: High-Frequency QPOs with a 3:2 Frequency Ratio

open access: yes, 2004
We observed the 2003 X-ray outburst of H1743-322 in a series of 130 pointed observation with RXTE. We searched individual observations for high-frequency QPOs (HFQPOs) and found only weak or marginal detections near 240 and 160 Hz.

HARMLESS Early Warning System for Advanced Materials

open access: yesAdvanced Sustainable Systems, EarlyView.
The HARMLESS Early Warning System tackles Advanced Materials (AdMa) risk governance by providing a framework, organised in two tiers, underpinned with methods/tools to support risk assessors in the pre‐assessment preceding risk assessment. It allows for initial screening to identify AdMa with concerns considering exposure, hazards, sustainability and ...

Sustainable Flame‐Retardant Poly Lactic Acid Biocomposites Reinforced with Polyphosphate‐Enriched Microalgae: Unlocking the Potential of Hyper‐Compensation

open access: yesAdvanced Sustainable Systems, EarlyView.
This study explores microalgae cultivation for wastewater treatment and enhancement of poly lactic acid (PLA)‐based biocomposites. It achieves up to 99.9% nutrient removal, increases biomass productivity by 322%, and demonstrates a triphasic luxury phosphorus uptake system. Incorporation into PLA improves fire‐retardant properties, suggesting potential
