Atomically Dispersed Molybdenum Catalysts for Efficient Ambient Nitrogen Fixation.
Angewandte Chemie, 2019 NH3 synthesis by the electrocatalytic N2 reduction reaction (NRR) under ambient conditions is an appealing alternative to the currently employed industrial method-the Haber-Bosch process-that requires high temperature and pressure.

Study on Process Mineralogy and Mineral Processing Technology of A Low Grade Copper-Molybdenum Ore
Kuangchan zonghe liyong, 2023 A copper-molybdenum ore in Qinghai contains 0.084% Mo and 0.067% Cu. Process mineralogical study shows that molybdenum in the ore mainly exists in the form of molybdenite, while copper in the form of chalcopyrite, chalcocite and bornite.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity
FEBS Letters, EarlyView.The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.
