Atomic force microscopy measurements of bacterial adhesion and biofilm formation onto clay-sized particles

Atomic force microscopy measurements of bacterial adhesion and biofilm formation onto clay-sized particles | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it
Bacterial adhesion onto mineral surfaces and subsequent biofilm formation play key roles in aggregate stability, mineral weathering, and the fate of contaminants in soils.
Ath Godelitsas's insight:

Atomic force microscopy (AFM) was used to determine the adhesion forces between bacteria and goethite in water and to gain insight into the nanoscale surface morphology of the bacteria-mineral aggregates and biofilms formed on clay-sized minerals.

Structural analysis of hierarchically organized zeolites

Structural analysis of hierarchically organized zeolites | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it
Advances in materials synthesis bring about many opportunities for technological applications, but are often accompanied by unprecedented complexity. This is clearly illustrated by the case of hierarchically organized zeolite catalysts, a class of crystalline microporous solids that has been revolutionized by the engineering of multilevel pore architectures, which combine unique chemical functionality with efficient molecular transport. Three key attributes, the crystal, the pore and the active site structure, can be expected to dominate the design process. This review examines the adequacy of the palette of techniques applied to characterize these distinguishing features and their catalytic impact.
