Purely ultrasonic enzyme extraction from activated sludge in an ultrasonic cleaning bath
MethodsX, 2017 Enzymes are important in biological wastewater treatment systems, since they are responsible for breakdown of macro- and micropollutants, thereby making the pollutants available for metabolism.

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how small and medium‐sized enterprises (SMEs) transition from a symbolic, disclosure‐oriented ESG logic toward a substantive ESG‐oriented performance management system (PMS) grounded in actionable KPIs. Drawing on evidence from the Apuan‐Versilian Stone Industrial District through an interventionist research design, we ...

Chemistry – A European Journal, EarlyView.A family of amino‐acid–derived MOFs enables ultrafast (>90–95% in 30 s) simultaneous removal of four estrogenic contaminants from water under SPE conditions. A leucine‐based MOF shows excellent regenerability and robustness in real samples, with structural evidence revealing efficient hormone encapsulation.
