Proficient Photocatalytic and Sonocatalytic Degradation of Organic Pollutants Using CuO Nanoparticles

Abstract: In recent years, due to the advancement in nanotechnology, advanced oxidation processes (AOPs), especially sonocatalysis and photocatalysis, have become a topic of interest for the elimination of pollutants from contaminated water. In the research work reported here, an attempt has been made to study and establish a physicochemical mechanism for the catalytic activity of copper oxide nanoparticles (CuO NPs) in AOPs using the degradation of dyes as model contaminants. CuO NPs exhibited brilliant sonocatalytic and photocatalytic activities for the degradation of a cationic dye (Victoria Blue) as well as an anionic dye (Direct Red 81). The degradation efficiency of CuO NPs was calculated by analysing the variation in the absorbance of dye under a UV-Vis spectrophotometer. The influence of different operating parameters on the catalytic activity of CuO NPs, such as the amount of catalysts dose, pH of the solution, and the initial dye concentration, was thoroughly investigated. In addition, the kinetic process for the degradation was also examined. It was observed that both dyes exhibited and followed the pseudo-first-order kinetics relation. The rate constant for sonocatalysis was high as compared to photocatalysis. The rate constant for both sonocatalysis and photocatalysis was successfully established, and reusability tests were done to ensure the stability of the used catalysts. To get an insight into the degradation mechanism, experiments were performed by using ⋅OH radical scavengers. The efficacy of CuO NPs for dye decolorization was found to be superior for the sonocatalyst than the photocatalyst.

Security Challenges of Networked Control Systems

Abstract: Networked control systems (NCSs) are created by the integration of advanced communication networks, control systems, and computation techniques. This integration enhances efficiency and reliability at the expense of increased complexity and reduced security . For example, the reliance of NCSs on communication networks exposes these systems to attack vectors targeting generic networks. This chapter is an overview of pervasive NCSs’ applications, recent attacks on NCSs, and attack detection techniques. A mathematical framework for an NCS under common types of attack is presented, i.e., denial of service (DoS), false data injection (FDI), and time delay switch (TDS) attacks. Thereafter, the framework is used to developed an algorithm based on adaptive channel allocation and state estimation techniques to compensate for the destabilizing effects of TDS and FDI attacks simultaneously. Finally, the proposed algorithm is used in a case study to show the effect of injected attacks on different parts of an NCS and the capabilities of the detection algorithms. Simulation results show the algorithm can accurately detect attacks and can overcome the attack effects by adapting the communication channels.

From hope to despair: the need for beginning teacher advocacy

Abstract: This article describes the experiences encountered by a first year teacher. The focus is on her stories from the field, and investigates the beginning teacher experience from eagerness and hope to frustration, despair and attrition. Narratives of the beginning teachers' experiences and acknowledgment of their personal and professional knowledge provide a framework for advocacy and implications for induction programmes. Advocacy for beginning teachers is situated in relationships with supportive administrators and teachers. As activists, experienced teachers and school principals are visible models of excellent practice, as well as of hope. Listening to the stories of beginners may provoke veteran educators to advocate for the next generation of teachers and reform professional practice.
