Equal volumes from each dish of conditioned medium were harvested, and 0.5 ml of human plasma (from outdated plasma obtained from the Tisch Hospital Blood Bank) was added as a carrier. A total of 4 ml of the sample was then adjusted to a density (d) of 1.2 g/l with KBr and loaded ...
Catalytic reduction of CO2 over Cu-based catalysts can produce various carbon-based products such as the critical intermediate CO, yet significant challenges remain in shedding light on the underlying mechanisms. Here, we develop a modified triple-stage
