Smart Governing System Based on Mesh Algorithm for Industrial Gas and Flame Detection with Alert System

The paper proposes a Wireless Sensor Network (WSN) solution for monitoring environmental parameters during industrial fires. The system includes sensors that collect real-time data on temperature ,humidity, and gas emissions. When the system detects a fire orgas out break ,it generates alerts and presents the data on a single webpage for easy visualization by first responders. The solution aims to provide near real time alerting, enabling prompt response to minimize the impact of industrial fires. The paper also presents experimental analysis of sensor node behavior during a fire in a test set-up, which demonstrated the effectiveness of the system in detecting fire outbreaks and generating alerts promptly. The proposed system has the potential to reduce the impact of industrial fires, including loss of human lives, vegetation, economic loss ,and environmental pollution

Synthesis of 5-phenyltetrazole and its N-methyl Derivatives in a Microreactor

Azidation of benzonitrile with dimethylammonium azide yielding 5-phenyltetrazole dimethylammonium salt was performed under microreactor conditions. The kinetics of azidation of benzonitrile in DMF was investigated at the range 80–95 °С. The reaction rate constants were determined:kII·104(L mol–1 s–1): 0.79, 0.97, 1.19, 1.51, at 80, 85, 90, and 95 °С, respectively. It was found that the reaction rate constants obtained in a microreactor are comparable to ones for a batch-type reactor. The thermodynamic parameters of azidation under the microreactor conditions correspond to the mechanism of the 1,3-dipolar cycloaddition of azides to nitriles. It was established that the excessive pressure in the microreactor notably accelerates the process. The alkylation of 5-phenyltetrazole with methyl iodide in microreactor was performed in dichloromethane-aqueous sodium hydroxide system. The accumulation of regioisomers of N1- and N2-methyl-5-phenyl tetrazole in the microreactor under the conditions of slug flow of the reaction mixture occurs considerably faster than in the batch-type reactor in the conditions of phase-transfer catalysis
