salt clathrate

Dr. Thien Nguyen (left) and Professor Cafer T. Yavuz (right) pose with a bottle of CO2-loaded guanidinium sulfate salt (held by Dr. Nguyen). The ten gas-filled, two-liter bottles in front represent the required space for the same amount of carbon dioxide that would be needed were it not being held in clathrate form (small bottle).
