Fe Single-Atom and Fe Cluster-Coupled N, S Co-doped Carbon Nanomaterial-Based Flexible Electrochemical Sweat Biosensor for the Real-Time Analysis of Uric Acid and Tyrosine.

Fe single-atom and Fe cluster-coupled N, S co-doped carbon nanomaterials (Fe-FeO-NSC) were prepared through a two-step high-temperature pyrolysis process using Gelidium corneum enriched with C, Fe, O, N, and S as precursors.

Adaptive evolution of pancreatic ribonuclease gene (RNase1) in Cetartiodactyla.

Pancreatic ribonuclease (RNase1), a digestive enzyme produced by the pancreas, is associated with the functional adaptation of dietary habits and is regarded as an attractive model system for studies of molecular evolution.
