AAMs are synthesized from either alumino- silicate or calcium aluminosilicate precursors in highly alkaline conditions [7]. The most common precursors are metakaolin, coal fly ash, and ground granulated blast fur- nace slag (GGBFS). Metakaolin derives from the calci- nation of naturally occurring ...
Although calcium carbonate is the most likely phase during carbonation reactions in aqueous solution, scawtite and spurrite may precipitate near the surfaces of dissolving silicate minerals, clays, or cement phases, particularly in the caprocks.Zhang, Y.-Q....
The sulfide-rich magmas were most likely transported upward from the staging chamber via magma overpressure attributable to considerable tectonic compressive stresses. It could be proposed that the sulfide-rich magmas were derived from a strongly evolved magma chamber, whereas the sulfide-barren mafic ...
To achieve these goals, one of the most promising pathways that has emerged relies on the introduction of small quantities of magnetic dopants as iron (Fe), cobalt (Co), or vanadium (V) into usually diamagnetic vdW material hosts to form dilute magnetic layered systems14,15,31,32,33,34,...
The Moon has a magmatic and thermal history that is distinct from that of the terrestrial planets1. Radioisotope dating of lunar samples suggests that most lunar basaltic magmatism ceased by around 2.9–2.8 billion years ago (Ga)2,3, although younger
Talc is themajor component of most powder makeup products(think face powder, eyeshadows, and blushers) that usually contain it up to 70%. Its two winning properties that make it very suitable for this role is itsoutstanding spreadabilityfor a smooth application and itslow covering power, aka...
(represented here by the mineral Enstatite, MgSiO3, a member of the pyroxite silicate mineral series that makes up most of the Earth’s mantle), and so on. The measured radii of Kepler-62e and Kepler-62f plus an estimate of their mass places them in a region (blue areas) where it ...
It meant that most of the Ca2+ and Mg2+ could be precipitated in our experiments by using the diisobutylamine + n-octanol system as the pH regulator. The vast-majority precipitation of Mg2+ in this experiment, which was not obtained in our previous work while using tributylamine + n-...
and suggests gene duplications and losses since the last common ancestor of the two species. From the phylogenies, it is obvious that scl-CA1 and scl-CA2 are not closely related and, therefore, most likely have been recruited independently in the biomineralization process. Neither scl-CA1s nor...
