Acoustic Monitoring of Inelastic Compaction in Porous Granular Materials [PDF]

open access: yesarXiv, 2023
We study the transition from cohesive to noncohesive granular states of synthetic rocks under oedometric loading, combining simultaneous measurements of ultrasound velocity and acoustic emissions. Our samples are agglomerates made of glass beads bonded with a few percent of cement, either ductile or brittle.

Modifications in Glass Ionomer Cements: Nano-Sized Fillers and Bioactive Nanoceramics

open access: yesInternational Journal of Molecular Sciences, 2016
Glass ionomer cements (GICs) are being used for a wide range of applications in dentistry. In order to overcome the poor mechanical properties of glass ionomers, several modifications have been introduced to the conventional GICs. Nanotechnology involves

Molar incisor hypomineralisation: current knowledge and practice

open access: yesInternational Dental Journal, EarlyView., 2020
Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Density functional modeling of the binding energies between aluminosilicate oligomers and different metal cations [PDF]

open access: yesarXiv, 2023
Interactions between negatively charged aluminosilicate species and positively charged metal cations are critical to many important engineering processes and applications, including sustainable cements and aluminosilicate glasses. In an effort to probe these interactions, here we have calculated the pair-wise interaction energies (i.e., binding ...
