Atomically dispersed single-atom catalysts(SACs)on carbon supports show great promise for H_(2)O_(2) electrosynthesis,but conventional wet chemistry methods using particulate carbon blacks in powder form have limited their potential as two-electron(2^(e−))oxygen reduction reaction(ORR)***,we demonstrate high-performance Co SACs supported on a free-standing aligned carbon nanofiber(CNF)using electrospinning and arc plasma deposition(APD).Based on the surface oxidation treatment of aligned CNF and precise control of the deposition amount in a dry-based APD process,we successfully form densely populated Co SACs on aligned *** experimental analyses and density functional theory calculations,we reveal that Co SAC has a Co–N_(2)–O_(2) moiety with one epoxy group,leading to excellent 2^(e−)ORR ***,the aligned CNF significantly improves mass transfer in flow cells compared to randomly oriented CNF,showing an overpotential reduction of 30 mV and a 1.3-fold improvement(84.5%)in Faradaic efficiency,and finally achieves an outstanding production rate of 15.75 mol gcat^(−1) h^(−1) at 300 mA cm^(−2).The high-performance Co SAC supported on well-aligned CNF is also applied in an electro-Fenton process,demonstrating rapid removal of methylene blue and bisphenol F due to its exceptional 2e^(−)ORR activity.

This research study aims to design and implement an advanced automation system for pelletizers, integrating load controltechnology to optimize pellet productionprocesses. Pelletizers are widely used in industries such as agriculture, food processing, and pharmaceuticals for converting raw materials into uniform pellets. However, traditional pelletizer systems often lack precise control over load conditions, leading to inefficiencies, inconsistencies, and potential equipment damage. Incorporation of load sensors into the pelletizer system to monitor the load exerted on the pelletizing blades or rollers in real-time. Load sensors will provide accurate feedback on the compression force applied during the pelletization process, enabling precise control and adjustment of pelletizer parameters. Implementation of an intuitive current rating and load to facilitate the controlled automation of pelletizing motors. A controller will provide operators with control options, real-time monitoring of load conditions, status updates, and alarm notifications, ensuring ease of operation and troubleshooting. Development of intelligent control logic and algorithms to optimize pelletization parameters dynamically based on load feedback and quality requirements. The proposed system will be capable of adjusting process parameters in real-time to accommodate variations in raw material properties and production conditions. Incorporation of data logging capabilities to record key process parameters, load profiles, and production metrics over time. Data analysis tools will enable performance evaluation, process optimization, and predictive maintenance scheduling. the paper aims to demonstrate the feasibility and advantages of integrating load controltechnology into pelletizer systems, leading to enhanced efficiency, precision, and safety in pellet productionprocesses.
