Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry
Advanced Science, EarlyView.The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

The Domus Nozze D'Argento in Pompeii: Structural Diagnosis Using Geophysical Methods
Archaeological Prospection, EarlyView.ABSTRACT Monitoring of ancient buildings is an issue of great interest in view of a proper restoration. This paper describes the noninvasive monitoring of the Domus Nozze D'Argento in Pompeii. The Roman house, as occurred for many other buildings in Pompei, was buried in the ash from the 79 ad eruption of Mount Vesuvius.
