In order to achieve the clean treatment of refractory cyanide tailings containing sulfur, a novel microwave-assisted chlorination thermal treatment recovery technology was proposed in this paper. On the basis of studying the mineralogy of cyanide tailings, the treatment capacity of common...

The flow and heat transfer characteristics of spiral rod (SR), twisted tape (TT), guide vane (GV) and thread grooves (TG) nozzles are compared by numerically and experimentally for swirl angle [[EQUATION]] and Reynolds number [[EQUATION]] . An experimental system is built to investigate the heat...

White et al. (2015) extend the vector autoregressive (VAR) for conditional mean to VAR for conditional quantiles (VAR-VaR) to capture the interdependencies among the quantiles of multiple time series. In this paper, we introduce a post-lasso estimator to extend VAR-VaR to the high-dimensional...

Electrochromic devices that reversibly switch between yellow and green have great potential in adaptive camouflage. However, such device with excellent performances for practical applications is scarce. Herein, we fabricated a new dual conjugated polymer electrochromic device based on two...

A Z-scheme heterojunction ZnO-C/MnO2 photocatalyst was successfully prepared by a simple method of chemical reduction deposition and secondary hydrothermal treatment. X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM) and scanning...
