Inhalation toxicity of mineral particles

, 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.

Effect of chemical mixing state on the hygroscopicity and cloud nucleation properties of calcium mineral dust particles [PDF]

Atmospheric Chemistry and Physics, 2009
Atmospheric mineral dust particles can alter cloud properties and thus climate by acting as cloud condensation nuclei (CCN) that form cloud droplets. The CCN activation properties of various calcium mineral dust particles were studied experimentally to ...

Cloud condensation nuclei activity of CaCO₃ particles with oleic acid and malonic acid coatings [PDF]

Atmospheric Chemistry and Physics, 2018
Condensation of carboxylic acids on mineral particles leads to coatings and impacts the particles' potential to act as cloud condensation nuclei (CCN). To determine how the CCN activity of mineral particles is impacted by carboxylic acid coatings, the

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Modeling of Scattering Cross Section for Mineral Aerosol with a Gaussian Beam

Journal of Nanotechnology, 2018
Based on the generalized Lorenz Mie theory (GLMT), the scattering cross section of mineral aerosol within the Gaussian beam is investigated, and an appropriate modeling of the scattering cross sections for the real mineral aerosols including the feldspar,

Organization of Bone Mineral: The Role of Mineral–Water Interactions

Geosciences, 2018
The mechanism (s) that drive the organization of bone mineral throughout the bone extracellular matrix remain unclear. The long-standing theory implicates the organic matrix, namely specific non-collagenous proteins and/or collagen fibrils, while a ...

Atom Probe Tomography as an Emerging Tool for Understanding Defect‑Driven Mechanisms in HfO2‑Based Ferroelectrics

Advanced Functional Materials, EarlyView.
This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...
