Phyllosilicates provide a primary source of minerals used by microorganisms and plants, particularly clay minerals, i.e., phyllosilicates of very small particle size.

The experiments were carried out at room temperature in presence of living microorganisms, Leonardite humic acid, bacterial debris, bacterial exopolysaccharides (EPS), and some organic ligands. The bacterial debris, EPS, Leonardite and organic ligands were chosen to stabilize Al in octahedral coordination for allowing the crystallization of kaolinite.

- Structural income inequality, defined as the uneven distribution of income across regions, affects brain dynamics and functions more significantly than individual factors like age or education.
- This study used EEG signals from 1,394 healthy participants across 10 countries to explore how structural inequality predicts various brain activity metrics, revealing a connection between socioeconomic conditions and neural functioning.
- Results show that higher structural income inequality is associated with lower brain signal complexity, increased random neural activity, and reduced power in certain brain wave frequencies, suggesting the need for a broader understanding of how social factors influence brain health.
The biological stability of solid waste is one of the main problems related to the environmental impact of landfills and their long-term emission potential. Current European legislation (European Landfill Directive, EC/99/31) introduced the need to reduce biodegradable organic compounds deposited in landfills; however, it set neither official parameters nor methods to define the stability of such a waste. In Spain, biodegradability is generally evaluated using the biological oxygen demand/chemical oxygen demand (BOD/COD) ratio, measuring it on the leachate, thus not considering the non-soluble fraction and therefore creating false negatives.
