Investigation of the change in the characteristic properties of epoxy and silane coated natural stone surfaces

open access: yesBulletin of the Mineral Research and Exploration
Travertine is a natural stone with macro and micropores; these pores are connected by capillary means. Their visual appearance and porous structure add a different style and diversify their usage areas.

Coral larval enhancement with and without nets yields similar recruitment during slack current releases

open access: yesRestoration Ecology, Volume 34, Issue 1, January 2026.
Abstract Introduction Restoring coral reefs through larval enhancement has the potential to scale interventions beyond experimental plots of tens of m2. However, the effectiveness of releasing larvae without confinement (“free release”) remains untested.

Dual Clumped Isotope (Δ47, Δ48) Values for Calcite Grown at Varying pH and Carbonic Anhydrase Concentrations Constrain Equilibrium and Kinetic Isotope Effects

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract This study explores the isotopologues m/z 47 (13C18O16O, denoted Δ47) and m/z 48 (12C18O2, denoted Δ48) in CO2 derived from carbonate minerals, focusing on their temperature dependency, kinetic isotope effects, and distinct reaction pathways. By conducting experiments at four temperatures (5°C, 10°C, 15°C, and 25°C) using the enzyme carbonic ...
