Emergence of Continents Stabilized the Bioavailability of Boron

Terra Nova, EarlyView.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Porosity Preservation in Deeply Buried (8500 m) Jurassic Calcareous Mudstones of the Vienna Basin (Austria)

Terra Nova, EarlyView.
ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

Streaming Computations in Feldspar

, 2014
We present a library for expressing digital signal processing algorithms using a deeply embedded language in Haskell. It is an extension Feldspar's stream library, which provides a data type for infinite sequences of values.

Cathodoluminescence of Feldspar Minerals

, 2012
A collection of North American feldspar minerals were examined using cold-cathode cathodoluminescence (CL) spectroscopy. The resulting spectra were fit and characteristic peaks were associated with each feldspar phase; these peaks are independent of ...

Soda Ash Free Batches for Novel Container Glass Compositions

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
A series of novel glass compositions incorporating up to 50% recycled cullet is melted from batches free of soda ash. Their viscosity–temperature, liquidus, and electrical conductivity characteristics are comparable to conventional soda–lime—silica glasses, enabling processing in conventional installations while markedly reducing batch‐to‐melt ...
