Self-cleaning Surfaces Resistant to Abrasion and Contamination

Treated glass surface.

Researchers from University College London (UK) developed a new paint which, when applied on surfaces, makes them superhydrophobic (very water repellant) and self-cleaning. Such surfaces are resistant to abrasion and handling; moreover, they maintain their properties even if contaminated with oil. These characteristics make them suitable for new everyday applications. Self-cleaning Surfaces Self-cleaning surfaces are […]

Carbon Dioxide Emissions from Brazilian Steel Production: Native Charcoal and Deforestation

Brazilian forest.

In a study published in Nature Climate Change, scientists show that the carbon dioxide emissions from Brazil’s steel production doubled in the 2000-2007 period, despite a decrease in the use of coal. According to the researchers, Brazil used native charcoal, i.e. charcoal produced from native forests, to fuel the steel-production industry… which led to deforestation and, […]
