Summary: This paper presents a comprehensive kinetic study comparing the performance of Nannochloropsis sp. and Tetraselmis sp. microalgae during pyrolysis and combustion processes. The results suggest that the thermal decomposition of microalgae involves multiple parallel decomposition reactions, and the kinetics were evaluated from each decomposition kinetic of the pseudo-components.

Summary: The synergistic influence of microalgae on the co-pyrolysis of biomass wastes and its digested form was evaluated in terms of thermal decomposition behavior, gas yields, extent of thermal decomposition, and reaction kinetics. Microalgae were found to have a significant impact on reaction kinetics, reducing the apparent activation energy and increasing total gas yields, thus aiding in the design and optimization of co-pyrolysis processes.

Summary: This study introduced a method for calculating resin content using thermogravimetric analysis (TGA) for carbon fiber/ poly (ether ether ketone) (CF/PEEK) composites. The TGA curves and DTG curves were divided into four stages, and the resin content was accurately obtained from the transitional stage and stable stage. Results compared with other methods showed that the TGA method was suitable for resin fraction calculation with slight difference.

Summary: Microalgae are a valuable natural resource for producing a variety of value-added products. The optimal light intensity for their growth is around 26,400 µmol photons m(-2) s(-1), with higher intensity leading to increased lipid synthesis and triacylglyceride content. Light intensity also affects the synthesis of fatty acids and carotenoids in microalgae biomass. Additionally, combining light with other stresses can enhance the productivity of algae.

Summary: This study investigated the effect of fine-toned fly ash content on the tensile performance of lightweight strain-hardening cementitious composites (LSHCC). It found that a fly ash content between 25% and 37.5% can achieve a balance between strength and ductility, making it suitable for creating sustainable materials.

Summary: This study proposed a novel methodology for predicting microalgae chlorophyll content using linear regression and artificial neural network. SPSS software was utilized for analysis, with extractant solvents and image indexes used as input data for the neural network calculation. The results showed a highly significant regression model with an R2 of 0.58 and RMSE of 3.16, making it a useful tool for chlorophyll concentration prediction. Meanwhile, the artificial neural network model achieved a higher accuracy with an R2 of 0.66 and low RMSE of 2.36. The experimental data suggested that acetone was a suitable extraction solvent, and the red-green-blue model offered a better correlation compared to the cyan-magenta-yellow-black model in image analysis. In summary, the estimation of chlorophyll concentration using prediction models is rapid, efficient, and cost-effective.

Summary: The study showed that blueberries had significantly higher nutrient and antioxidant content compared to cranberries and raspberries, with the exception of crude fiber. Fourier infrared spectroscopy was used to quantitatively characterize the composition differences of the tissues of these three berries. Specific differences were identified through the comparison of relative absorption intensities and second derivative spectra.

Summary: This study investigates CO2 biofixation and pyrolytic kinetics of microalga G. pectorale. The experimental results show that the highest rate of CO2 fixation occurs at a CO2 concentration of 2%. Multiple pyrolysis peaks were observed in the thermogravimetric analysis. Different model-free methods were used to calculate the activation energy, and the results were in good agreement with the experimental values. The multilayer perceptron-based artificial neural network regression model demonstrated excellent agreement with the experimental values of thermal decomposition.
