Lego-like assembly of zeolitic membranes improves carbon capture

Zeolites are porous minerals that occur both naturally but also are being synthesized artificially. Because they are stable and durable, zeolites are used for chemical catalysis, purification of gases and liquids, and even ...

Nano-sponges of solid acid transform carbon dioxide to fuel and plastic waste to chemicals

The primary cause of climate change is atmospheric CO2, and levels are rising every day. There is, therefore, a great need to find ways to reduce CO2 levels. On other hand, an excessive amount of plastic waste has become ...
