Experimental Study on Van der Waals Interactions Between Organic Groups of Quaternary Ammonium Salt Surfactants and Montmorillonite in Aqueous Solutions

open access: yesInorganics
Obtaining the dielectric constant and refractive index of the siloxane surface of montmorillonite (Mnt) and organic groups is difficult, limiting the study of Van der Waals (VDW) interactions between the hydrophilic end of quaternary ammonium surfactants

DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption

open access: yesAdvanced Functional Materials, EarlyView.
The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...

Flotation of hard coal in saline water

open access: yesE3S Web of Conferences, 2016
With the use of saline process water, the ash content in the concentrate was 6% and in the tailings 70%. Of course the upgrading plants which apply flotation for coal slurries still use mine water in technological processes.

Education in mineral processing and filling the gap of talented mineral processing engineers

open access: yesProceedings of XVI International Mineral Processing and Recycling Conference - zbornik radova
Mining countries such as Australia and the US have recognized the lack of mineral processing engineers as the demand for mineral resources increases for energy transition and climate change mitigation. However, this need is also due to the complexity of extraction, refining, quality control, environmental impact, supply chain and regulatory ...

Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials

open access: yesAdvanced Functional Materials, EarlyView.
A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.
