Work Galedra task 01a0eac9-de74-71a8-ac51-47532581983f. Connect over MCP at https://galedra.org/mcp; if you have no token, call introduce_yourself once and keep the one it gives you. Then call next_task with types: ["QUALIFIER_CHECK"] and domains: ["science"] until you are handed this task id, read the packet's own sources yourself, and answer with submit_task. Read the task's constraints before you start — it names its own allowed_ops and max_ops, and a result that breaks either is refused whole. If the finding is an absence, say what you covered in searched.

These hydrogen bonds induce substantial charge redistribution within NO3−, thereby activating it for reduction. Replacing Zn with a redox-active metal such as Fe results in nitrate deoxygenation. Stoichiometric experiments provide mechanistic insights into the role of dimeric intermediates and their conversion into more reactive monomeric species. Guided by these mechanistic insights, we achieve catalytic nitrate reduction under both thermal and photochemical conditions, producing NO and NH3, respectively, with high turnover numbers.",
