Witryna29 lis 2024 · The reduction of background impurities has largely been addressed via empirical approaches for each impurity being considered. This work successfully addresses both challenges simultaneously: smooth N-polar GaN with low oxygen incorporation. In order to achieve this, a morphology control layer is implemented in … Witryna16 mar 2024 · We found that CO production was unaffected by SO x compounds in a 3.0 M KHCO 3 feedstock, but 2000 ppm of NO x impurities decreased CO selectivity from ∼60% to <5%. This decrease was caused by the preferential reduction of NO 2– and NO 3– over CO 2. Our study establishes tolerance limits for common flue gas …
Witryna29 mar 2024 · We’ll determine the quality of the split by weighting the impurity of each branch by how many elements it has.
