Near field modelling of dust emissions caused by drilling and crushing

open access: yesSN Applied Sciences, 2020
This study compares modelling results to measured concentrations near dust sources in a natural stone quarry and in two aggregate quarries. In the natural stone quarry, the dust source was drilling and in the aggregate quarries, it was crushing.

Computable aggregations [PDF]

open access: yesInformation Sciences, 2018
In this paper, we postulate computation as a key element in assuring the consistency of a family of aggregation functions so that such a family of operators can be considered an aggregation rule. In particular, we suggest that the concept of an aggregation rule should be defined from a computational point of view, focusing on the computational ...

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

open access: yesMolecules, 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.

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

open access: yesAdvanced 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

open access: yesNature 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 ...

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

open access: yes, 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,

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

open access: yesAggregate, 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 ...
