Shou‐Dong Zhang, Zhijun Ma, Chen‐Chen Feng, David S. Melville, more

Journal of Avian Biology > 50 > 10 > n/a - n/a

Especially in birds, it is widely found that the size of individual prey items follows the size of the instruments of prey capture, handling and processing, i.e. bill size. In fact, this is the natural history basis of major discoveries on adaptive evolution in the face of changing food resources. In some birds, e.g. the molluscivore shorebirds ingesting hard‐shelled prey, most of the prey processing...

PdAg bimetallic electrocatalyst for highly selective reduction of CO₂ with low COOH* formation energy and facile CO desorption

Rui Lin, Xuelu Ma, Weng-Chon Cheong, Chao Zhang, more

Nano Research > 2019 > 12 > 11 > 2866-2871

For electrocatalytic reduction of CO₂ to CO, the stabilization of intermediate COOH* and the desorption of CO* are two key steps. Pd can easily stabilize COOH*, whereas the strong CO* binding to Pd surface results in severe poisoning, thus lowering catalytic activity and stability for CO₂ reduction. On Ag surface, CO* desorbs readily, while COOH* requires a relatively high formation energy, leading...
