Abstract Silicone is often used in environments where water repellency is an advantage. Contact with water promotes the adhesion of microorganisms and biofilm formation. Depending on the application, this may increase the possibility of food poisonin

It is highly desirable to synthesise heteroatom-doped carbon-based materials in an environmentally friendly and simple way, which possess good electrocatalytic activity towards the oxygen reduction reaction (ORR). Therefore, in this study, we focused

Construction of road embankments in peatlands commonly involves replacement of the peat with a fill-up soil of an adequate load-bearing capacity. This usually requires a lowering of the water level, turning a peatland from a carbon sink to a source o
