Bone formation in sinus augmentation with different xenograft particle sizes: systematic review and meta-analysis

open access: yesRGO: Revista Gaúcha de Odontologia, 2022
The commercial bovine bone mineral most commonly used is available in two particle sizes and studies have demonstrated contradictory results regarding bone formation volume using small or large particles.

Aggregation as a function of and mineral particles [PDF]

open access: yesLimnology 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 ...

Dithiothreitol‐Measured Oxidative Potential of Reference Materials of Mineral Dust: Implications for the Toxicity of Mineral Dust Aerosols in the Atmosphere

open access: yesGeoHealth, 2023
Oxidative stress is a mechanism that might raise the toxicity of mineral dust aerosols. We evaluated the oxidative potential (OP) of four reference materials (RMs) of mineral dusts using dithiothreitol assay.

Chemical composition of ambient aerosol, ice residues and cloud droplet residues in mixed-phase clouds: single particle analysis during the Cloud and Aerosol Characterization Experiment (CLACE 6) [PDF]

open access: yes, 2009
Two different single particle mass spectrometers were operated in parallel at the Swiss High Alpine Research Station Jungfraujoch (JFJ, 3580 m a.s.l.) during the Cloud and Aerosol Characterization Experiment (CLACE 6) in February and March 2007.

Inhalation toxicity of mineral particles

open access: yes, 2022
S.223-228Many of the mineral particles that are of concern in regard to lung toxicity are poorly soluble particles (PSPs). They include biopersistent mineral fibers and dusts containing crystalline silica.

Surface pre-coating of talc particles by carboxyl methyl cellulose adsorption : study of adsorption and consequences on surface properties and settling rate [PDF]

open access: yes, 2006
This paper investigates the adsorption of different sized carboxyl methyl cellulose (CMC) onto talc particles (adsorption isotherm, adsorption reversibility), its consequences on the particles properties (electrophoretic mobility and surface wetting) and

Silylated Thiol-Containing Cellulose Nanofibers as a Bio-Based Flocculation Agent for Ultrafine Mineral Particles of Chalcopyrite and Pyrite [PDF]

open access: yes, 2021
<jats:title>Abstract</jats:title><jats:p>A considerable amount of very fine particles can be found, e.g., stored in tailing ponds, and they can include valuable or hazardous minerals that have the potential to be recovered.

Mineralized Collagen Fibrils: A Mechanical Model with a Staggered Arrangement of Mineral Particles [PDF]

open access: yesBiophysical Journal, 2000
Both elastic modulus and fracture stress are known to increase with the amount of mineral deposited within collagen fibrils. Current mechanical models of mineralized fibrils, where mineral platelets are arranged in parallel arrays, reproduce the first effect but fail to predict an increase in fracture stress.

Dataset of mineral contents of fine-sand and silt-sized soil particles from deserts in China and Mongolia

open access: yesData in Brief, 2021
There are over 70 types of mineral species in desert soils. Previous data have focused on major mineral contents and thus, the identification of minor mineral species is lacking.
