PFRs were produced on biochar during Cr(VI) decontamination. PFRs formation on biochar was owing to the oxidization of phenolic-OH by Cr(VI). Appearance of excessive oxidant led to the consumption of PFRs on biochar. Biochar charred at high temperature possessed great performance to Cr(VI) removal.

Cell membrane of indigenous Cd-tolerant EAB harbored more cadmium than chromium. Indigenous Cd-tolerant EAB cytoplasm located more chromium than cadmium. Simultaneously quantitatively imaging Cd(II) and Cr(III) ions in EAB was achieved. Current accelerated the harboring of cadmium in EAB at an initial 2 h. Current directed the accumulation of more chromium in EAB over time.

In recent years, much effort has been focused on the development of the photocatalysts with high performance under visible light irradiation. In this paper, three-dimensional porous La-doped SrTiO3 (LST) microspheres were prepared by a modified sol–gel method, in which the agarose gel/SrCO3 microsphere and La2O3 were employed as the template and the La resource, respectively. The as-prepared LST microspheres exhibit a porous structure with a diameter of about 10 µm and a surface pore size of about 100 nm. The La element was doped into the crystal lattice of SrTiO3 by the substitution of La3+ for Sr2+. Therefore, the absorption edge of LST samples shifts toward the visible light region, and their photocatalytic activity for the Cr(VI) reduction is enhanced under visible light. Among all LST samples, LST-0.5 (the La3+ doping content is 0.5 wt-%) exhibited the highest visible-light photocatalytic activity, which can reduce 84% Cr(VI) within 100 min. This LST materials may become a promising photocatalyst for the facile treatment of wastewater containing poisonous heavy metal ions.

The aim of this paper was to address the rolling contact fatigue (RCF) failure mechanisms of plasma-sprayed Cr3C2-NiCr coatings under different tribological conditions of contact stress. Weibull distribution plots of fatigue lives of the coated specimens at different contact stresses were obtained. The failure modes of coatings were identified on the basis of wore surface observations of the failed coatings. Results showed that the RCF failure modes can be classified into four main categories, i.e., surface abrasion, spalling, cohesive delamination, and interfacial delamination. The probabilities of the surface abrasion and spalling type failures were relatively high at low contact stress. When the coatings were subjected to abrasion and spalling type failures, the failure of the coating was depended on the microstrcture of the coating. The stress concentration near the micro-defects in the coating may be the may reason for the formation of spall. The coatings were prone to fail in delamination under higher contact stresses. However, the delamination of coating may be related to distribution of shear stress amplitude within coating. The location of maximum shear stress amplitude can be used as a key parameter to predict the initiation of subsurface cracks within coating in rolling contact.
