Recent Progress in Type I Aggregation-Induced Emission Photosensitizers for Photodynamic Therapy

Molecules, 2022
In modern medicine, precision diagnosis and treatment using optical materials, such as fluorescence/photoacoustic imaging-guided photodynamic therapy (PDT), are becoming increasingly popular. Photosensitizers (PSs) are the most important component of PDT.

Fractal dimension of fumed silica: Comparison of light scattering and electron microscope methods [PDF]

, 2010
Due to the enormous increase in nanopowder production, it becomes necessary to find and develop adapted characterization techniques. In the case of nanostructured agglomerates, the structure of these particles has a direct impact on flowing, and handling,

Site‐Selective, Multistep Functionalizations of CO2‐Based Hyperbranched Poly(alkynoate)s toward Functional Polymetric Materials

Advanced Science, 2020
Hyperbranched polymers constructed from CO2 possess unique architectures and properties; however, they are difficult to prepare. In this work, CO2‐based, hyperbranched poly(alkynoate)s (hb‐PAs) with high molecular weights and degrees of branching are ...

All-fluorescence white organic light-emitting diodes with record-beating power efficiencies over 130 lm W‒1 and small roll-offs

Nature Communications, 2022
High power efficiency and low roll-off values are essential to the commercialization of white organic light-emitting diodes. Here, the authors construct all-fluorescence devices with an orange emitting layer sandwiched between two sky-blue emitting ...

Collisions between sintered icy aggregates [PDF]

, 2017
Collisions between sintered icy dust aggregates are numerically simulated. If the temperature of an icy aggregate is sufficiently high, sintering promotes molecular transport and a neck between adjacent grains grows.

An activatable NIR‐II fluorescent probe for tracking heavy‐metal ion and high‐level salt‐induced oxidative stress in plant sprouts

Aggregate, 2023
Humans and plants have become enfolded and inseparable. Abiotic stresses in particular oxidative stress caused by heavy‐metal ions or high‐level salt contamination deleteriously impact plants’ growth process and have become a major threat to sustaining ...
