Summary: This study presents and compares two different pathways of lignin conversion to bio-jet fuel from corn stalks. The one-step conversion pathway yields higher bio-jet fuel and cumulative exergy efficiency compared to the two-step conversion pathway. Biomass conversion to bio-jet fuel with self-supplied hydrogen aids in converting low-quality biomass into high-quality bio-jet fuel and reducing fossil fuel consumption. Sensitivity analysis shows that the hydrolysis efficiency of lignin has the greatest impact on cumulative exergy efficiency, while the furfural yield from hemicellulose has the lowest impact.

Summary: Searching for high thermal conductivity materials is a long-term endeavor. Comparing the thermal conductivities of selected carbon allotropes, we found that a high symmetry operation number and a small atom number in the primitive unit cell can reduce the phonon-phonon scattering phase space. Through comprehensive searching of a carbon allotrope database, we found that the bcc-C6 allotrope has a high thermal conductivity due to its high symmetry operation number and small atom number. The calculated lattice thermal conductivity of bcc-C6 can reach 2198 W/m K at room temperature if its atomic packing fraction equals that of diamond.

Summary: Anaerobic digestion is a promising method for reducing sewage sludge and recovering energy. A comparative life cycle assessment was conducted to evaluate different anaerobic digestion processes. The results show that anaerobic digestion combined with cogeneration and digestate incineration is advantageous to high energy recovery, but incineration is disadvantageous to economic performance. The study also revealed that the environmental damage is largest in the process of thermophilic anaerobic digestion with digestate incineration, while the smallest load is in mesophilic anaerobic digestion with digestate landfilling. Overall, thermophilic anaerobic digestion combined with thermal hydrolysis pre-treatment exhibits the best resource performance, and digestate incineration and CAD-2 show better comprehensive performance. The deep drying incineration process has better comprehensive performance than sewage sludge anaerobic digestion processes.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
