Synthesis of vinasse-dolomite nanocomposite biochar via a novel developed functionalization method to

Nima Kamali, Abdollah Rashidi Mehrabadi, Maryam Mirabi, Mohammad Ali Zahed

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 4, doi: 10.1007/s11783-020-1249-6

Abstract: Abstract • Nanocomposites were prepared by adding dolomite to vinasse at different ratio. • Textural and morphological features of adsorbents were studied in detail. • CCD based RSM was used for investigation of P ion removal by nanocomposite. • The qm based on Langmuir model for modified vinasse biochar was 178.57 mg/g. • P loaded nanocomposite improved plant growth and could be utilized as P-fertilizer. The effectiveness of phosphate (P) removal from aqueous solutions was investigated by novel low-cost biochars synthesized from vinasse and functionalized with calcined dolomite. The vinasse-derived biochar, synthesized via pyrolysis at different temperatures, showed easy preparation and a large surface area. The novel vinasse biochar nanocomposites were prepared by adding dolomite to the vinasse biochars with different weight percentages (10, 20 and 30%). The characteristics of the prepared materials were identified for further understanding of the inherent adsorption mechanism between P ions and vinasse biochars. Vinasse-dolomite nanocomposite was very effective in the adsorption of P species from aqueous media. The effect of the operational factors on Vinasse-dolomite nanocomposite was explored by applying response surface methodology (RSM). According to RSM results, the optimum condition was achieved to be contact time 90 (min), 250 (mg/L) of P concentration and pH 7. Thermodynamic isotherm and kinetic studies were applied on experimental data to understand the adsorption behavior. The Vinasse-dolomite nanocomposite revealed preferential P species adsorption in the presence of co-existing anions. The P species could be recovered by 1.0 M HCl where the efficiency was not affected up to the fifth cycle. The P-loaded Vinasse-dolomite nanocomposite was successfully tested on a plant; it significantly improved its growth and proved its potency as a P-based fertilizer substitute.

Theoretical study of vibrating effect on heat transfer in laminar flow

Baoxing LI, Maocheng TIAN, Xueli LENG, Zheng ZHANG, Bo JIANG

Frontiers in Energy 2010, Volume 4, Issue 4,   Pages 542-545 doi: 10.1007/s11708-010-0026-9

Abstract: Green’s function method was adopted to study the problem of vibrating effect on heat transfer in laminar flow with constant flux and the influence of Prandtl number and the vibrating frequency on the heat transfer characteristics was investigated. The results show that the variation of the frequency leads to a different distribution of the unsteady velocity and temperature; with a lower frequency, the vibrating will weaken the heat transfer, but the heat transfer will be enhanced with a higher frequency. A lower Prandtl number leads to a strenuous variation of heat transfer.

Situational awareness architecture for smart grids developed in accordance with dispatcher’s thought Review

You-bo LIU,Jun-yong LIU,Gareth TAYLOR,Ting-jian LIU,Jing GOU,Xi ZHANG

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 11,   Pages 1107-1121 doi: 10.1631/FITEE.1601516

Abstract: The operational environment of today’s smart grids is becoming more complicated than ever before. A number of factors, including renewable penetration, marketization, cyber security, and hazards of nature, bring challenges and even threats to control centers. New techniques are anticipated to help dispatchers become aware of the accurate situations as they manipulate and navigate the situations as quickly as possible. To address the issues, we first introduce the background for this topic as well as the emerging technical demands of situational awareness in the dispatcher’s environment. The general concepts and technical requirements of situational awareness are then summarized, aimed at offering an overview for readers to understand the state-of-the-art progress in this area. In addition, we discuss the importance of integrating the architecture of support tools in accordance with the dispatcher’s thought process, which in fact guides correct and swift reactions in real-time operations. Finally, the prospects for situational awareness architecture are investigated with the goal of presenting situational awareness modules in an advanced and visualized manner.
