Small concentrations, big results: μM addition of photoactive iron oxides with ...
Jia, Jialin; Minella, Marco; Ruiz, Mercedes Cid; Decker, Jeremie; Li, Dong; Gonçalves, Nuno P. F.; Prevot, Alessandra Bianco; Lin, TaoThe photo-Fenton process is effective for pathogen removal, and its low-cost versions can be applied in resource-poor contexts. Herein, a photo-Fenton-like system was proposed using low concentrations of iron oxides (hematite and magnetite) and persulfates (peroxymonosulfate - PMS, and peroxydisulfate - PDS), which exhibited excellent inactivation performance towards MS2 bacteriophages. In the presence of bacte...
From rust to robust disinfectants: How do iron oxides and inorganic oxidants sy...
Jia, Jialin; Minella, Marco; Del Castillo González, Isabel; Lehmann, Aurelio Hernández; Li, Dong; Gonçalves, Nuno P. F.; Prevot, Alessandra BiancoPathogens in drinking water remain a challenge for human health, photo-Fenton process is a promising technique for pathogen inactivation, herein, two common iron oxides, hematite and magnetite mediate persulfate (peroxymonosulfate-PMS - and peroxydisulfate-PDS) involved photo-Fenton-like processes were constructed for E. coli inactivation, and the inactivation performance was investigated and compared with the ...
Dissecting the Shared Genetic Architecture of Suicide Attempt, Psychiatric Diso...
Mullins, Niamh; Kang, JooEun; Campos, Adrian I; Coleman, Jonathan R I; Edwards, Alexis C; Galfalvy, Hanga; Levey, Daniel F; Lori, AdrianaBackground: Suicide is a leading cause of death worldwide, and nonfatal suicide attempts, which occur far more frequently, are a major source of disability and social and economic burden. Both have substantial genetic etiology, which is partially shared and partially distinct from that of related psychiatric disorders. Methods: We conducted a genome-wide association study (GWAS) of 29,782 suicide attempt (SA) c...
Hybrid effect of fibre mesh and short fibres on the biaxial bending behaviour o...
Li, Dong; Ding, Yining; Wang, Qing; Zhang, Yongchao; Azevedo, Cecília; Zhang, YulinTextile mesh-reinforced concrete (TRC) and mortar have been studied in recent years. However, current testing methods are focused on simply supported members under uniaxial bending; these are inadequate for analysis of a biaxially tensioned fibre mesh and incapable of revealing the biaxial behaviour of a TRC panel. Moreover, the fibres can be damaged by the alkalinity of concrete. To overcome this inadequacy, a...
Quantitative analysis of macro steel fiber influence on crack geometry and wate...
Ding, Yining; Li, Dong; Zhang, YulinIn this work, the water permeability of the cracked concrete has been investigated. Three types of cylindrical specimens with different fiber content were pre-cracked by the feedback controlled splitting test, and the specimens without any fiber reinforcement were also studied as reference. The water permeability of the specimens with different crack width was measured by hydraulic permeability test. The coordi...
Experimental investigation on the composite effect of steel rebars and macro fi...
Ding, Yining; Li, Dong; Zhang, Yulin; Azevedo, CecíliaIn this study, the impact behavior of ten types of high performance self-compacting concrete (HPSCC) was explored using the drop-weight method. The HPSCC specimens were reinforced with steel rebars and different fibers for comparison with plain concrete. The reinforcement mechanism of the influences of steel rebars and different fibers on failure impact energy was explained. The composite effects of hybrid use ...
