Summary: This study investigated the use of a combined drying system using low-pressure superheated steam drying and heat pump drying for fish. The effects of different drying medium pressures on temperature field, airflow field, drying time, equipment performance, and power consumption were examined. The results showed that high vacuum resulted in more uniform temperature field and airflow field in the drying chamber, but also increased drying time. Furthermore, decreasing the drying medium pressure led to reduced power consumption of the heat pump and axial fans, while increasing the power consumption of the electric heater.

Summary: The battery monitoring system (BMoS) is essential for monitoring the battery's condition and determining optimal limits for long battery life. This is achieved by measuring battery parameters and increasing the state of charge (SoC) and state of health (SoH). The battery dataset from NASA is used for evaluation, and the gradient vector and support vector machine (SVM) are utilized to analyze the battery's energy supply pattern and accuracy index. The degradation rate of the battery can be calculated to apply this strategy in real situations. The error values obtained using voltage gradient, SVM method, and polynomial regression enable the determination of the battery's SoC dynamics and resolution of SoH problems.

Summary: This study investigated the thermogravimetric behavior, kinetics, and product distribution of CO2-assisted biomass direct chemical looping (CO2-BDCL). The results showed that there were small interactions between cellulose and lignin, which slightly reduced the activation energy of the lignin-cellulose mixture. There was no apparent interaction between pyrolysis and gasification for lignin. The activation energy at high temperatures was generally reduced in the presence of CO2. CO2-BDCL promoted lignin conversion, gaseous yield, and reduced tar formation.

Summary: Hydrogen is a clean energy source but has low volumetric density, and thus effective storage is needed. Ammonia has the potential to be an effective hydrogen storage material due to its high gravimetric and volumetric densities, carbon-free nature, existing infrastructure, and possibility for direct utilization. However, there are challenges in ammonia utilization, such as low combustion performance and the emission of NOx. This review discusses the characteristics of ammonia during combustion, technologies for ammonia combustion, and efforts to address the challenges in ammonia combustion.
