Phosphorus Coupling Obfuscates Lithium Geospeedometry in Olivine

Frontiers in Earth Science, 2020
Lithium zoning in zircon and olivine provides a powerful record of crystal histories and magmatic processes in volcanic systems. Characterizing Li behavior in olivine is important because it is one of the few elements in basaltic systems that track short-

Dust absorption and scattering in the silicon K-edge [PDF]

, 2019
The composition and properties of interstellar silicate dust are not well understood. In X-rays, interstellar dust can be studied in detail by making use of the fine structure features in the Si K-edge.

Affordable Automated Modules for Lab‐Scale High‐Throughput Synthesis of Inorganic Materials

Chemistry – A European Journal, EarlyView.
A semi‐automated high‐throughput synthesis station, developed within the MAITENA platform, features two modular units: one for solid‐state and wet‐chemistry routes (ceramic, sol‐gel, Pechini), and another for microwave‐assisted solvothermal synthesis. It enables reproducible workflows, phase diagram exploration, and morphology control, demonstrated on ...

Mineralogical Characterization of Baptistina Asteroid Family: Implications for K/T Impactor Source

, 2011
Bottke et al. (2007) linked the catastrophic formation of Baptistina Asteroid Family (BAF) to the K/T impact event. This linkage was based on dynamical and compositional evidence, which suggested the impactor had a composition similar to CM2 carbonaceous

Temperature effects on the 15-85-micron spectra of olivines and pyroxenes [PDF]

, 2001
Far-infrared spectra of laboratory silicates are normally obtained at room temperature even though the grains responsible for astronomical silicate emission bands seen at wavelengths >20 micron are likely to be at temperatures below ~150 K.

How to Produce Green Hydrogen from Olivine and Seawater? By Ultrasound

ChemSusChem, EarlyView.
Power ultrasound provides efficient production of green hydrogen from olivine and seawater under near‐ambient conditions. The sonochemical alteration of olivine involves particle fragmentation, the removal of the passivating layer, and local, transient heating in the vicinity of collapsing bubbles.
