Obtaining Highly Crystalline Barium Sulphate Nanoparticles via Chemical Precipitation and Quenching in Absence of Polymer Stabilizers

Journal of Nanomaterials, Volume 2015, Issue 1, 2015., 2015
Here we report the synthesis of barium sulphate (BaSO4) nanoparticles from Ba(OH)2/BaCl2 solutions by a combined method of precipitation and quenching in absence of polymer stabilizers. Transmission electron microscopy (HRTEM), Fourier transforms infrared spectroscopy (FTIR), and X‐ray diffraction (XRD) were employed to characterize the particles.

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
