Summary: A polycondensate-coated cellulose nanofiber (CNF) hybrid was designed and used as a nanofiller for fabricating CNF-reinforced polylactic acid (PLA) composites. The polycondensate coatings effectively promoted the dispersion of CNFs and enhanced the interfacial compatibility between CNFs and PLA. The resulting composites exhibited significant improvements in processing, mechanical, and thermal properties.

Summary: This study proposes a strategy of reinforcing polylactic acid (PLA) with biochar microspheres (BM), which have even particle size and regular morphology. Although the addition of BM decreases the toughness of PLA, the nucleation effect of BM facilitates crystallization and improves the tensile strength and modulus of BM/PLA composite films. The best tensile strength and modulus are achieved with 2% BM added and 3% added composite films.

Summary: The catalytic pyrolysis of Douglas fir using nanocellulose derived biochar catalyst significantly enhances the production of phenolic monomers and hydrogen. Under certain temperature and ratio conditions, the concentrations of phenol, cresols, and dimethylphenols can be greatly increased or decreased. Reusing the biochar catalysts still leads to a much higher concentration of phenolic monomers and hydrogen compared to processes without catalysts.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
