The combination of compelling language and the confidence it demonstrates may lead people to accept the LLM as a knowledgeable source even when it provides false information (Azaria & Mitchell, 2023). In this position paper, we wish to stress the importance of studying the interaction between ...
The use of generative AI and AI-assisted technologies in scientific writing must be declared by adding a statement at the end of the manuscript when the paper is first submitted. The statement will appear in the published work and should be placed in a new section before the references list....
reported a no-bonding Co and Pt dual-single-atom on polymeric carbon nitride (CN) for long-range electronic modulation, in which Co1N4 site can be effectively tuned to Co1N3, filled with unpaired d-electrons to be excited under irradiation, by loading single-atomic Pt1N4 process, thus ...
Molecules that covalently engage target proteins are widely used as activity-based probes and covalent drugs. The performance of these covalent inhibitors is, however, often compromised by the paradox of efficacy and risk, which demands a balance between
