Abstract:
... Fluffy honeycomb-like activated carbon with ultra-high surface area and well-developed hierarchical porous structure is simply prepared from popcorn by NaOH activation as adsorbent for dye removal. The popcorn has an unique fluffy structure, which originates from the corn via a rapid puffing process and is reserved during the following carbonization and NaOH activation. The ultra-high surface area ...

Abstract:
... Food tastes better and people eat more of it when eaten with company than alone. Although several explanations have been proposed for this social facilitation of eating, they share the basic assumption that this phenomenon is achieved by the existence of co-eating others. Here, we demonstrate a similar “social” facilitation of eating in the absence of other individuals. Elderly participants tasted ...
