Deep Underground Science and Engineering, EarlyView.A series of water infiltration tests and gas permeability tests were conducted on granite and granite–bentonite samples. According to the results, the interfaces between granite and bentonite and the damaged granite were considered to be the preferentcial pathway for gas migration.

Nutrient enrichment—but not warming—increases nitrous oxide emissions from shallow lake mesocosms
Limnology and Oceanography, EarlyView.Abstract Shallow lakes and ponds play a crucial role in the processing of carbon and other nutrients. However, many lakes and ponds worldwide are affected by climate change and nutrient pollution. How these pressures affect the emission of the greenhouse gas nitrous oxide (N2O) is unclear.
