Re-extracting environmentally transportable hexavalent uranium from wastew-ater produced by spent fuel reprocessing using the photocatalytic technology is a crucial strategy to avoid uranium pollution and recover nuclear fuel strategic ***,we have designed S-scheme 2D/0D C_(3)N_(5)/Fe_(2)O_(3)heterojunction photocatalysts based on the built-in electric field and the energy band bend-ing theory,and have further revealed the immobilization process of hexavalent uranium conversion into relatively insoluble tetravalent uranium in terms of thermodynamics and *** to the results,the hexavalent uranium removal and recovery ratios in wastewater are as high as 93.38%and 83.58%,***,C_(3)N_(5)/Fe_(2)O_(3)heterojunctions also exhibit satisfactory cat-alytic activity and selectivity even in the presence of excessive impurity cations(including Na^(+),K^(+),Ca^(^(2+)),Mg^(2+),Sr^(2+),and Eu^(3+))or various organics(such as xylene,tributylphosphate,pyridine,tannic acid,citric acid,and oxalic acid).It is believed that this work can provide a potential opportunity for S-scheme heterojunction photocatalysts to re-enrich uranium from spent fuel wastewater.

The research involves the addition of 5 vol.%TiB_(2)particles into AA8009 alloy powder to synthesize TiB_(2)/AA8009 composite parts produced via laser powder bed fusion(LPBF).The addition of the TiB_(2)particles causes the TiB_(2)/AA8009 composites with and without annealing have lower compressive strength than AA8009 alloy due to the change of the strengthening *** results further indicated that solid solution strengthening was the main strengthening mechanism of the LPBF AA8009 alloy at room temperature whereas Orowan strengthening became the primary strengthening factor after annealing at 673 *** contrast,Orowan strengthening always remained the main strengthening mechanism for the TiB_(2)/AA8009 composite,irrespective of the annealing *** addition,after annealing of the LPBF parts at 673 K,the compressive yield strength(CYS)of the unblended AA8009 alloy specimens had a~2.5 times greater reduction(from 705±16 to 459±30 MPa)compared to that of the composite TiB_(2)/AA8009 samples(from 466±23 to 368±3 MPa).Therefore,TiB_(2)particles can suppress the drop in yield strength of LPBF AA8009 alloy below 673 K,providing a theoretical and experimental basis for the applications of both LPBF AA8009 and TiB_(2)/AA8009 alloys at low and medium temperatures.
