Using data from a randomised experiment in Kenya, we estimate the causal effect of social networks on technology adoption. In this experiment, farmers were invited to information sessions about the use of Tissue Culture Banana (TCB), an in vitro banana cultivation technology. We find that an...

The weak inherent non-covalent interactions between carbon aerogel backbone nanoparticles obtained by pyrolysis of conventional organic aerogel can lead to poor mechanical properties. When applied in thermal protection system of high-speed spacecraft, the preparation of carbon aerogel insulation...
