- Abstract:
- ... Radiological atmospheric releases require population dose calculation for proper determination of preventive measures. The old concept of relative concentrations requires long lasting constant emission which is not realistic.The proposed concept of the “relative doses” is the generalization and expansion of the known concept of relative concentrations. Relative doses allow an evaluation of the gen ...

- Abstract:
- ... This perspective reviews mobile micro/nanomotor scaffolds for performing “chemistry-on-the-fly”. Synthetic nano/micromotors offer great versatility and distinct advantages in diverse chemical applications owing to their efficient propulsion and facile surface functionalization that allow these mobile platforms to move and disperse reactive materials across the solution. Such dynamic microreactors ...

Accurate determination of the basic characteristics for dispersion fundamentally supports the predication of pollutant transport especially in the transient stage. This work analytically studies the transient dispersion of an initial point pollutant concentration in wetland flows through the phase av ...

- Abstract:
- ... Phthalates are ubiquitous pollutants in residential environments. Indoor airborne phthalate concentrations in Chinese residences are comparable to, or even higher than, those of western countries. However, the major sources of phthalates in Chinese residences are not well-known. In this study, we measured the phthalates emission features of 23 flat materials used in Chinese residences in the labor ...

Although WO3 cannot be used for photocatalytic degradation of organic pollutants alone, it can significantly enhance photocatalytic efficiency through a Z-scheme photocatalytic system by coupling with CdS. The optimal pseudo-first-order reaction rate constant ...

An inverse analysis method for the real-time monitoring of pollutant diffusion is developed based on fuzzy adaptive Kalman filter (FAKF) coupled with weighted recursive least squares algorithm (WRLSA). In the monitoring process, the discrete diffusion states equation is established first. Then, the FAKF is adopted to realize the precise monitoring of the pollution diffusion states while the WRLSA ...

In addition to its strong contaminant sorption capability, biochar also plays an important role in chemical transformation of contaminant due to its inherent redox-active moieties. However, the transformation efficiency of inorganic contaminants is generally very limited when the direct adsorption of contamin ...

The simultaneous removal of phosphates, Zn2+ and Orange II, in two synthetic wastewaters was achieved using Al–Mg and Al–Zn–In alloys as anodes at 11.7 mA cm–2 and a surface area to volume ratio of 19.0 m–1. Higher removal efficiencies were obtained with Al–Zn–In, attaining values of 95–96% for phosphate, 99% for Zn2+ and 88–96% for Orange II, while somewhat lower values were seen with Al–Mg, with ...
