Fines Formation (and Prevention) in Seeded Precipitation Processes
KONA Powder and Particle Journal, 2014 An overview of three studies on seeded precipitation in a fluidised bed reactor (FBR) is presented. The objective of using the FBR is to remove dissolved metals as precipitated metal salts onto a seed surface.

The impact of outgassing of CO2 and prior calcium precipitation to the isotope composition of calcite precipitated on stalagmites. Implications for reconstructing climate information from proxies [PDF]
Chemical Geology 589, 120676, 2022, 2021 Degassing of CO2 and precipitation of calcite to the surface of stalagmites can strongly impact isotope signals imprinted into the calcite of these speleothems. Here, we show that in all the variety of conditions occurring in nature only two distinct types of degassing exist.

Phenotypic continuum of NFU1‐related disorders
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 2025-2035, December 2022., 2022 Abstract Bi‐allelic variants in Iron–Sulfur Cluster Scaffold (NFU1) have previously been associated with multiple mitochondrial dysfunctions syndrome 1 (MMDS1) characterized by early‐onset rapidly fatal leukoencephalopathy. We report 19 affected individuals from 10 independent families with ultra‐rare bi‐allelic NFU1 missense variants associated with a

Spiral precipitation patterns in confined chemical gardens [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Chemical gardens are plant-like mineral forms existing in nature at various scales. Even though they have been described for more than three centuries thanks to their beauty and analogies with biological forms, their growth mechanisms remain largely not understood.

Some characteristics of chemical precipitation [PDF]
Tellus B, 1983 Two very dissimilar cold frontal occlusions deposited 6 mm and 60 mm of rain respectively at anobservatory in the rural northeastern U.S.A. Water precipitation was carefully observed. in conjunction with other meteorological parameters, through both storm systems.The concentration of several ionic substances were measured in specimens of rain ...

Quantification of classical and non-classical crystallization pathways in calcite precipitation [PDF]
, 2022 Crystal precipitation from aqueous solution occurs through multiple pathways. Besides the classical ion-by-ion addition, non-classical crystallization mechanisms, such as multi-ion polymer and nano-particle attachment, could be of great significance under certain circumstances.
