Double-reaction-centers (DRCs) Fenton-like chemistry with low or zero oxidant addition has garnered increasing attentions due to their alignment the principles of green and sustainable development. However, regulation such processes remains a significant challenge, primarily deficiencies in microscopic interpretation electron migration mechanisms operating addition. In this work, iron single-atom DRCs catalyst (Fe/N-SAC) was prepared for internal-driven system (zero addition) external-driven (low peroxymonosulfate [PMS] addition). Results indicated absence dissolved oxygen activation PMS-zreo Fe/N-SAC system, single atoms acted as predominate acceptors extract electrons from electron-donating pollutants valence decreasing +2.37 +2.07 they could also be recovered under O2 atmosphere. contrast, transferred both PMS Fe/N-SAC/PMS involving predominant transfer process (ETP) internal-driven. Furthermore, two experimental devices based on core systems were designed achieve long-term operation. These studies will complement catalytic module applications systems.

Semi-continuous casting is an important method for the large-scale production of high-strength conductive copper-iron (Cu-Fe) alloys in future. However, serious peeling defects were found on surface cold-rolled strips during industrial trials. Due to multi-step complexity manufacturing process (from final product), identifying root cause defect formation remains challenging. X-ray computed tomography (X-CT) was used quantitatively characterize pores and horizontal continuous Cu-Ni-Sn slab, semi-continuous Cu-Fe alloy hot-rolled slab Cu-Fe, relationship between characteristics processes analyzed. The results showed that internal sphericity distribution after hot rolling similar reference slab. main difference lies low range (<0.4). volume pore inside significantly larger than sample, with a 52-fold difference. This phenomenon may be source surface-peeling subsequent cold-rolling process. occurrence related both composition alloy; other hand, it also hot-rolling
