Laboratory-generated mixtures of mineral dust particles with biological substances: characterization of the particle mixing state and immersion freezing behavior [PDF]
Atmospheric Chemistry and Physics, 2016 Biological particles such as bacteria, fungal spores or pollen are known to be efficient ice nucleating particles. Their ability to nucleate ice is due to ice nucleation active macromolecules (INMs).

Arteriosclerosis, Thrombosis, and Vascular Biology, 2021 Hypercalcemia and hyperphosphatemia associate with an elevated risk of cardiovascular events, yet the pathophysiological basis of this association is unclear. Disturbed mineral homeostasis and the associated hypercalcemia and hyperphosphatemia may result in the formation of circulating calciprotein particles (CPPs) that aggregate the excessive calcium ...

Characterization of individual ice residual particles by the single droplet freezing method: a case study in the Asian dust outflow region [PDF]
Atmospheric Chemistry and Physics, 2018 In order to better characterize ice nucleating (IN) aerosol particles in the atmosphere, we investigated the chemical composition, mixing state, and morphology of atmospheric aerosols that nucleate ice under conditions relevant for mixed-phase clouds.

Mineral particle disintegration model
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The study proposes mathematical model for reducing the size of mineral particles in crushing and grinding operations, which is a form of the reflected normal Gaussian – Laplace distribution. The study considers the distribution density modification of the mineral particles depending on the magnitude of the energy impact during ...

‘Mineral particles and the environment’: introduction [PDF]
Mineralogical Magazine, 2003 The study of mineral particles has become increasingly important in the earth sciences, especially in the emerging field of environmental mineralogy. The Mineralogical Society highlighted this by dedicating its Spring Meeting in April 2001, held in Kingston University, Surrey, UK, to the subject.

Aggregation as a function of and mineral particles [PDF]
Limnology and Oceanography, 2014 A laboratory experiment was designed to investigate the effects of ocean acidification (three levels) in the presence or absence of the clay mineral illite (five concentrations) on the coagulation of organic particles. The formation of aggregates > 1 mm from marine detritus and phytoplankton, and their characteristics and sinking velocity, were ...
