Development of physics-based compositional parameters for predicting the reactivity of amorphous aluminosilicates in alkaline environments [PDF]
The reactivity of amorphous aluminosilicates in alkaline environments is important to many applications, including blended Portland cements and alkali-activated materials (AAMs). Here, two physics-based compositional parameters are derived to describe the relative reactivity of CaO-Al2O3-SiO2 and CaO-MgO-Al2O3-SiO2 glasses in alkaline environments: (i)

Analysis of PM2.5 Morphology, Composition and Health Risk in a Multi‐Chair Dental Clinic
ABSTRACT Particulate matter with aerodynamic diameter ≤ 2.5 μm (PM2.5) at high concentrations in dental clinics poses significant health risks to healthcare professionals. However, the morphology and chemical composition of PM2.5 in specific environments are not yet fully elucidated.

The glassy structure of reactive supplementary cementitious materials (SCMs) and recycled glass: Contribution of XRD and Raman spectroscopy to their characterization [PDF]
This study compares thirteen natural and industrial samples of supplementary or emerging supplementary cementitious materials (SCMs): slag, fly ashes, pozzolan, obsidian, silica fume, and recycled glass. These materials are used or are under consideration for decarbonization in cement plants.

Association of macroscopic laboratory testing and micromechanics modelling for the evaluation of the poroelastic parameters of a hardened cement paste [PDF]
The results of a macro-scale experimental study performed on a hardened class G cement paste [Ghabezloo et al. (2008) Cem. Con. Res. (38) 1424-1437] are used in association with the micromechanics modelling and homogenization technique for evaluation of the complete set of poroelastic parameters of the material.

Abstract Background Whether to replace or repair a composite restoration is controversial and varies among clinicians. This study was designed to collect information on the attitudes and practices of Australian dentists towards composite repair. Methods An electronic 16‐item questionnaire was distributed online on Australian clinicians’ dental forum ...

Predicted field-induced hexatic structure in an ionomer membrane [PDF]
Coarse-grained molecular-dynamics simulations were used to study the morphological changes induced in a Nafion$^{\tiny \textregistered}$-like ionomer by the imposition of a strong electric field. We observe the formation of novel structures aligned along the direction of the applied field.
