Year: 2025
Type: article
Abstract: In this study, an automated device for the synthesis of nanostructures was developed, enabling precise regulation and maintenance of key parameters for the transformation of precursor oxides into nanostructured materials. The system is capable of automatically sustaining predetermined operating conditions depending on the properties of the starting reagents and the specific objectives of the experiment, while simultaneously recording data at defined intervals for subsequent analysis. This approach significantly reduces experimental errors and enhances the accuracy and reproducibility of the results. The core of the device is based on the Arduino Uno microcontroller platform, which controls critical components of the setup, including the heating system and the stirrer drive. Particular attention was given to the implementation of rotational viscometry, wherein real-time measurements of current and voltage on the motor enable direct correlation of these parameters with changes in the suspension’s viscosity. This allows the viscosity to serve as an indicator of the kinetics of structural transformations during the formation of vanadium pentoxide nanobelts. The device software incorporates algorithms for precise rotation counting using an encoder and smooth speed control, ensuring stable experimental conditions over extended periods, which can last several weeks. Automated data acquisition and storage in CSV format further optimize the subsequent processing and analysis of experimental results. The developed system not only ensures high reproducibility of the synthesis process but also provides a platform for advancing characterization methods of oxide nanomaterials and exploring new approaches in nanostructure fabrication.
