Chromium(VI) poses a major threat to public health and the ecological environment. Fe-C micro-electrolysis can be utilized as a potential sustainable strategy for improving Cr(VI) reduction in constructed wetlands (CWs). However, to date, the role of the microbial-driven Fe cycle for Cr(VI)...

Two-dimensional Fe-beidellite/carbon (Fe-BEI@C) superlattice-like heterostructure was prepared by intercalation of glucose in the gallery of layered Fe-BEI followed by calcination. The interlaminar and superficial carbon coating enables Fe-BEI to have good rate performance, fast lithium-ion...

Iron- and manganese-based layered metal oxides, as cathodes in sodium ion batteries, have received widespread attention because of the low cost and high specific capacity. However, the Jahn-teller effect of Mn 3+ ions and resulting unstable structure usually leads to continuously capacity decay....

In the present research, a geopolymer based on red mud was prepared for immobilisation of Pb 2+ and Cr 3+ , with the aim of improving the utilisation rate of red mud, which also represents an efficient and low-cost material for heavy metal solidification and grouting engineering. We investigate...

This study presents a novel approach for wind farm micro-siting in complex terrain based on an improved Genetic Algorithm (GA). The proposed approach is used for optimizing the layout of wind turbines in a real terrain in Changsha, China. Firstly, a combination of computational fluid dynamics...

To meet the requirements of efficient adsorption of atmospheric pollutant SO 2 and low energy consumption regeneration of adsorbent, biomass carbon materials modified by metal oxides were prepared under microwave heating and the effects such as microwave power, loading of iron oxides, and...

Abstract In this study, Ni-Cu alloy foam reinforced Sn-3.0Ag-0.5Cu (SAC305) composite solders (Ni-Cu-Sn) were used as an interlayer to solder Al alloy at 250℃. The microstructure evolution and mechanical properties of the two different joints were investigated. When soldering for 1 min, the...

This article sketches a picture of the self-employment sector in rural China and examines the nature of its emergence. Using a randomly selected, nationally representative household-level data set that contains detailed information on household self-employment activities, this article provides...

Using a conventional multi-region, multi-sectoral global trade analysis project (GTAP) model, we analyze the effects of India’s trade liberalization policies on its output, trade, and welfare. We also analyze three trade policy scenarios: full trade liberalization, joint cooperative trade...
