Archaeometry, EarlyView.
ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...

Water sorption of dental resin composites: Is a new method the future?

European Journal of Oral Sciences, EarlyView.
Abstract Intraoral, diffusion‐controlled water sorption leads to dimensional expansion and mechanical degradation over time. Measurement of small quantities of water in dental resin composites (RCs) is challenging, as current techniques rely on weighing approaches. Here, we evaluate Karl‐Fischer Titration (KFT) and thermogravimetry (TG) as alternatives

A Portable Multi‐Parameter Fluid Monitoring Unit for Real‐Time Measurements During Well Development and Geothermal Operations

Groundwater Monitoring &Remediation, EarlyView.
Abstract Monitoring of fluid parameters during well development, groundwater production, or geothermal operation is essential for the understanding of subsurface and well processes. We developed FluMoMax, a portable fluid monitoring unit, that can measure several physicochemical parameters in real‐time, to monitor fluid characteristics and to enable ...
