title: Preparation of high-performance anthracite-based graphite anode materials and their lithium storage properties

description: In this study, cost-effective anthracite and industrial silicon powder were used as precursor and catalyst, respectively, to prepare graphite with various structure, during which the catalytic mechanism was analyzed. The results demonstrate that the asobtained sample with 5% silicon catalyst (G-2800-5%) exhibits the best overall lithium storage performance. In detail, G-2800-5% display the best graphite structure with graphitization degree of 91.5%. As anode materials, a high reversible capacity of 369.0 mAh g-1 can be achieved at 0.1 A g-1. Meanwhile, the reversible capacity of 209.0 mAh g-1 can be obtained at the current density of 1 A g-1. It also delivers good cyclic stability with a 92.2% retention after 200 cycles at 0.2 A g-1. The highly developed graphite structure, whichis favorable to the formation of stable SEI and reduced lithium ion loss should be responsible for the superior electrochemical performance.

title: Recovery of high purity Si from kerf-loss Si slurry waste by flotation method using PEA collector
title: Recovery of high purity Si from kerf-loss Si slurry waste by flotation method using PEA collector

description: Separation and recovery of high-purity Si powder from kerf-loss Si slurry waste is a critical challenge for the photovoltaic industry. A green surfactant poly (propylene glycol) bis (2-aminopropyl ether) (PEA) was employed as a collector to facilitate the separation of Si and SiC from kerf-loss Si waste during flotation process. Single flotation tests of Si and SiC were conducted using 5 x 10(-6) mol/L PEA, respectively. The separation efficiencies of Si and SiC in conjunction with PEA adsorption mechanism were investigated. It was found that the maximum recoveries rate of SiC and Si were 90.59% (pH 9.00) and 80.93% (pH 1.96), respectively. Furthermore, the maximum Si grade was determined as 92.31% at pH 8.95 for the sinking part of the mixture generating excellent floatability and selectivity. Zeta potential measurements, FT-IR spectra, and XPS analyses demonstrated that PEA was present on the surface of Si and SiC through electrostatic and hydrogen-bond interactions. The adsorption mechanism was explained based on the results. This research provides an efficient and environmentally friendly route for the separation and recovery of high purity silicon from kerf-loss Si waste. (C) 2020 Elsevier Ltd. All rights reserved.

title: Separation and Recovery of Refined Si from Al-Si Melt by Modified Czochralski Method
title: Separation and Recovery of Refined Si from Al-Si Melt by Modified Czochralski Method

description: Separation of refined silicon from Al-Si melt is still a puzzle for the solvent refining process, resulting in considerable waste of acid and silicon powder. A novel modified Czochralski method within the Al-Si alloy is proposed. After the modified Czochralski process, a large amount of refined Si particles was enriched around the seed crystalline Si and separated from the Al-Si melt. As for the Al-28%Si with the pulling rate of 0.001 mm/min, the recovery of refined Si in the pulled-up alloy (PUA) sample is 21.5%, an improvement of 22% compared with the theoretical value, which is much larger 1.99 times than that in the remained alloy (RA) sample. The content of impurities in the PUA is much less than that in the RA sample, which indicates that the modified Czochralski method is effective to improve the removal fraction of impurities. The apparent segregation coefficients of boron (B) and phosphorus (P) in the PUA and RA samples were evaluated. These results demonstrate that the modified Czochralski method for the alloy system is an effective way to enrich and separate refined silicon from the Al-Si melt, which provide a potential and clean production of solar grade silicon (SoG-Si) for the future industrial application.

title: #ENDSARS PROTESTS AND THE IMPERATIVE FOR STATE POLICE IN NIGERIA

description: The issue of police brutality and human rights abuses have been attributed to the failure of the Nigeria Federal Police Force, especially its most notorious former unit known as SARS, which has since been disbanded by the police authority due to several civil society agitations, such as #EndSARS protest movement. The EndSARS protests further revealed the vulnerabilities and inadequacies of Nigeria’s Federal Police Force, and the movement has become a wakeup call for the creation of state police as a better policing option for addressing the complex security challenges in Nigeria, such as fraud, armed robbery, kidnappings, car snatching, cyber criminality, terrorism, cattle rustling, insurgency, and so on. It is in this regard that this article examined EndSARS protests and the imperative for state police in Nigeria, using the secondary method of data and personal observation of the protests in Delta State, where the protests started. The paper found that the political, religious, and ethnic colouration accorded the EndSARS protests by the ruling class was the reason why EndSARS peaceful protesters in Lekki, Lagos, Nigeria, were killed in cold blood, and it was also the reason why several demands of the protesters were not met beyond the disbandment of SARS unit. Hence, a need for a state police in Nigeria as a better policing option. Several recommendations aimed at achieving the objectives of the articles were suggested, such as: The amendment of the constitution to ensure the creation of state police; creating the state police to co-exist with the federal police; appointing only the people who are vast in the local knowledge and language, as well as people with a track record of honesty and transparency into the state police force; ensuring adequate funding for state police project; making provision for a robust capacity building of the state police officials; the federal police to be in charge of interstate security; State governments should ensure that unviable programmes like the Religious Pilgrimage Boards that sponsor pilgrims to annual religious pilgrimages are scraped and the funding for such programmes should be deployed to funding state police project, and so on.

title: Vibration Control of an Experimental Flexible Manipulator Against Input Saturation

description: This letter considers the control problem of an experimental flexible manipulator in position tracking, vibration suppression, and saturation compensation. Based on the backstepping technology and a Nussbaum function, we develop an anti-windup control to restrain the manipulator’s vibration, realize the desire trajectory tracking,and eliminate the saturation. Applying the Lyapunov’s method, the control system’s stability with the proposed control is proved. Finally, the practicability and effectiveness of the control methodology are verified on a Quanser experiment platform.
