Phase-out is rapidly gaining traction as a central part of practical efforts to address sustainability challenges. However, the way it has been conceived in policy debates and some academic work problematic that (1) tends be narrowly focused on substitution; (2) underexposes bi-directional relationship between phase-outs innovation; (3) pays insufficient attention political To fully reap potent...
Ammonium nitrate (AN) is widely used in fertilizers, civilian explosives and military explosives. Due to crystalline phase transitions and density changes of AN in the ambient conditions, its usage as oxidizer in solid propellants has some limitations as compared to ammonium perchlorate (AP). Several methods have been introduced to overcome these problems. In the present paper, the phase transi...
Declines in pollinator populations may harm biodiversity and agricultural productivity. Little attention has, however, been paid to the systemic response of mutualistic communities to global environmental change. Using a modelling approach and merging network theory with theory on critical transitions, we show that the scale and nature of critical transitions is likely to be influenced by the a...
