Abstract

A magnetic nano-composites Fe3O4@SiO2@MnO2 were fabricated for efficient removal of Th(IV) from aqueous solutions, and characterized by SEM, TEM, XRD, FT-IR, BET, VSM, TGA and XPS. And the sorption of Th(IV) on Fe3O4@SiO2@MnO2 were investigated as a function of pH, adsorbent dosage and initial Th(IV) concentration. The results showed that the adsorption maximum was 53.19 mg g−1 for Th(IV) at pH = 3.5 and T = 298 K. In addition, the adsorption kinetics followed the second-order kinetic model, and the adsorption isotherm could be perfectly depicted by the Langmuir model. Finally, XPS analysis illustrated that the lattice oxygen (M–O) and the surface hydroxyl oxygen (M–OH) participated in adsorption. In brief, the Fe3O4@SiO2@MnO2 material could efficiently eliminate Th(IV) from aqueous solutions, which might become a promising material for adsorbing Th(IV) from environmental wastewater.

Abstract

A kind of new five-level software architecture is presented in this paper, which is designed elaborately for ultra-large-scale rendering cloud. This software architecture consists of five levels, infrastructure layer, rendering service layer, rendering application layer, service management and access interface. Based on the proposed software architecture, we have developed a new type of rendering management software called Golden Farm Cluster Rendering Platform. And comprehensive tests have been carried on the super computer, Tian He 1A. Experimental results show that Golden Farm can effectively manage the rendering jobs on ultra-large-scale high performance cluster with up to 2000 computing nodes and also obtain good performance. In addition, the platform has created an important record, rendering a 3D model by using 24000 CPU cores in parallel.
