Characterization of bentonite clay from 'Greda' deposit

Processing and Application of Ceramics, 2011
Based on mineralogical and technological investigations of the deposit 'Greda' important characteristics of bentonite clay were determined. Representative samples of the deposit were characterized with X-ray diffraction, low-temperature nitrogen adsorption, chemical analysis, differential thermal analysis and scanning electron microscopy.

A pellet‐based approach for moss biocrust inoculation: high establishment under laboratory conditions, challenges in the field

Restoration Ecology, EarlyView.
Abstract Introduction Biological soil crusts (biocrusts) are key components of soil ecosystems and promising tools for ecological restoration. Mosses, as important biocrust constituents, contribute to ecosystem functioning but often fail to establish after inoculation due to harsh environmental constraints.
