Mineral physics and mineral chemistry in Canada

Eos, Transactions American Geophysical Union, 1990
A number of different groups in Canada carry out research on the physics and chemistry of minerals. The majority of the research is conducted within universities, with the remainder occurring at government laboratories. Research groups span a wide range of disciplines, which include physics, chemistry, and materials science, as well as geology.Mineral ...

Changes in dissolved iron deposition to the oceans driven by human activity: a 3-D global modelling study [PDF]

, 2015
The global atmospheric iron (Fe) cycle is parameterized in the global 3-D chemical transport model TM4-ECPL to simulate the proton- and the organic ligand-promoted mineral-Fe dissolution as well as the aqueous-phase photochemical reactions between the ...

Mesenchymal Stem Cells‐Derived Extracellular Vesicles Mimetics as Osteoinductive Mediators for Bone Healing

Advanced Functional Materials, EarlyView.
Mesenchymal stem cell‐derived nanoghosts (MSC‐NGs) mimic naturally secreted extracellular vesicles (MSC‐EVs) in structure and physicochemical properties but can be synthesized at more translatable yields. As osteogenic agents, MSC‐NGs demonstrate superior outcomes compared to MSC‐EVs.

Thermal insulation materials on the basis of microsilica [PDF]

Vestnik MGTU, 2015
The main areas of silica application have been examined in the paper. It has been found that microsilica can be used in manufacture of wollastonite-containing ceramic matrixes and composite materials with expanding shale and nepheline-process waste as ...

Grain boundaries in minerals: atomic structure, phase transitions, and effect on strength of polycrystals [PDF]

arXiv, 2021
Grain boundaries (GBs) and interfaces in polycrystalline materials are significant research subjects in the field of materials science. Despite a more than 50-year history of their study, there are still many open questions. The main challenge in studying interfacial structures is the extreme complexity of their experimental and theoretical observation

How does the local wind field control the aerosol distribution in coastal Dronning Maud Land? [PDF]

, 2011
Atmospheric circulation patterns and chemical concentrations in firn cores are highly related to each other. Atmospheric winds transport aerosols like sea salt and mineral dust over the globe and redistribute them.

Soluble silicon patterns and templates: calcium phosphate nanocrystal deposition in collagen type 1 [PDF]

, 2016
Patterned mineralisation is a feature of many hard-tissues. The impressive mechanical properties exhibited by such tissues can be, in part, attributed to the patterned deposition of mineral within the organic matrix.

Reclamation of reactive metal oxides from complex minerals using alkali roasting and leaching- an improved approach to process engineering [PDF]

, 2015
In nature, the commonly occurring reactive metal oxides of titanium, chromium, aluminium, and vanadium often chemically combine with the transition metal oxides such as iron oxides and form complex minerals.

Hierarchically Engineered Triple‐Defensive Antifouling Coating with Well‐Regulated Structure for Enhanced Wastewater Treatment

Advanced Functional Materials, EarlyView.
Inspired by shark skin, which has a hydrophilic “denticle layer” and a low surface energy “mucus layer,” a triple‐defense antifouling coating is developed. This coating features a robust hydrophilic catalytic nanoparticle layer overlaid with dispersed hydrophobic perfluoro‐silane domains, optimizing fouling resistance, release, and degradation for ...
