Summary: In this study, the trans-esterification of used cooking oil biodiesel was catalyzed by nano zinc oxide particles with Tungsto phosphoric acid. The optimal reaction parameters were determined to achieve a maximum conversion rate of 94%. Synthetic biodiesel blends were used for engine testing and analysis, and their storage stability and fuel properties were evaluated. The addition of nano zinc oxide particles with Tungsto phosphoric acid decreased the peroxide values of biodiesel blends, leading to increased stability.

Summary: This paper explores the impact of chicken waste on the performance and emission characteristics of a direct injection diesel engine. It examines different blends of hydrogen and biodiesel derived from chicken fat at various engine speeds. The results indicate that hydrogen enriched biodiesel improves performance in terms of thermal efficiency and power, while also lowering fuel consumption. However, there are still concerns regarding emissions, as all biodiesel blends show a slight increase in nitrogen oxide and carbon dioxide emissions regardless of engine speed.

Summary: Color is a prime feature that directly influences consumers' attraction and choice of food. The flavor, safety, and nutritional value of food products are closely related to their color. Natural and synthetic colorants have diverse applications in various industries. While synthetic colorants are popular due to their stability and affordability, previous studies have highlighted their toxicological, carcinogenic effects, hypersensitivity reactions, and behavioral changes. In contrast, natural colorants have nutraceutical qualities and beneficial properties such as antioxidants, anti-inflammatory effects, and health benefits.

Summary: The study focused on the effect of polydopamine (PDA) modification on the removal of a cationic dye (methylene blue) and an anionic dye (Congo red) from waters using -Fe3O4-NH2/ GO/CDP-CA composites. It was found that the PDA/Fe3O4-NH2/ GO/CDP-CA composite exhibited higher adsorption capacities for both dyes compared to -Fe3O4-NH2/GO/CDP-CA. The sorption behaviors were explained by the surface-charged properties of the composites. Furthermore, the composites showed good recyclability and reusability.

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.
