Photocatalysis is a promising advanced water treatment technology, and recently the possibility of using hydrogenation to improve photocatalytic efficiency titanium dioxide has generated much research interest. Herein we report that use high-temperature prepare black TiO2 primarily results in formation bulk defects material without affecting its electronic band structure. The hydrogenated exhibited significantly worse activity under simulated sunlight compared unhydrogenated control, thus...
Oil sands process-affected water (OSPW), generated from bitumen extraction in the Canadian oil sands, may require treatment to enable safe discharge receiving watersheds, as dissolved naphthenic acids (NAs) and other acid extractable organics (AEO), identified primary toxic components of OSPW, are environmentally persistent poorly biodegradable. However, conventional advanced oxidation processes (AOPs) impractically expensive treat volumes OSPW stockpiled Athabasca region. Here we prepared...
A new method is presented for the synthesis of monodisperse, size-tunable Fe3O4 spherical nanocluster particles through a simple, one-step hydrothermal reaction, according to kinetics-controlled self-assembly process smaller nanocrystals into hierarchical mesoporous aggregates. The mean diameter can be controlled over broad range up ~230 nm by simply varying concentration precipitating reagent (urea or ammonia). easily dispersed in water with excellent colloidal stability, exhibit high...
Photocatalysis over titanium dioxide is a promising technology for water purification and degradation of emerging contaminants, however, catalyst efficiency recovery after the photocatalytic reaction are key challenges that have limited practical deployment TiO2 in treatment applications. Herein we report synthesis core-shell, superparamagnetic gamma-Fe2O3@SiO2@TiO2 colloidal nanospheres with mesoporous shell, their characterization, application photocatalysis. The final surface area...
Abstract Understanding the formation and evolution of ring galaxies, which possess an atypical ring-like structure, is crucial for advancing knowledge black holes galaxy dynamics. However, current catalogs galaxies are limited, as manual analysis takes months to accumulate appreciable sample rings. This paper presents a convolutional neural network (CNN) identify from unclassified samples. A CNN was trained on 100,000 simulated transfer learned onto real applied previously data set generate...
The morphology-dependent localized surface plasmon resonance of gold nanostructures has been widely utilized for designing sensors. One method relies on the color change nanoparticles upon etching. In previous work, TMB2+oxidized from 3,3',5,5'-tetramethylbenzidine (TMB) was found to etch nanorods (AuNRs), leading a spectrum different colors. However, preparation TMB2+needs addition strong acid and other harsh conditions. Herein, new colorimetric biosensing platform developed using...
Understanding the formation and evolution of ring galaxies, galaxies with an atypical ring-like structure, will improve understanding black holes galaxy dynamics as a whole. Current catalogs rings are extremely limited: manual analysis takes months to accumulate appreciable sample existing computational methods vastly limited in terms accuracy detection rate. Without sizable rings, further research into their properties is severely restricted. This project investigates usage convolutional...
