Summary: A highly efficient selective aldehyde decarbonylation reaction has been developed using a heterogeneous Ni(0) nanospecies catalyst supported on CeO2, with a broad substrate scope and functional group tolerance. The high catalytic performance is attributed to the highly dispersed and non-electron-rich N(0) nanospecies, which suppress side reactions and CO-derived inhibition of catalytic turnover.

Summary: The study investigated the catalytic activity and stability of nickel, platinum, rhodium, and ruthenium-based catalysts during hydrogen production from steam reforming of liquefied petroleum gas. It was found that rhodium and platinum catalysts exhibited higher catalytic activity and lower deactivation compared to nickel and ruthenium catalysts. Small increases in particle sizes of Ni(0) and Ru(0) during the process could contribute to the faster deactivation of Ru/CS and Ni/CS catalysts.

Summary: Biodiesel obtained from the transesterification of vegetable oils contains polyunsaturated fatty esters which negatively affect its oxidation stability. Catalytic partial hydrogenation can upgrade biodiesel by converting polyunsaturated fatty esters into monounsaturated methyl oleate. In this study, polymer-supported palladium and nickel nanoparticles were tested as catalysts for upgrading biodiesels under mild conditions. The palladium catalyst showed high activity but poor selectivity, while the nickel catalyst exhibited lower activity but higher selectivity. The recyclability tests demonstrated that the nickel-based system can retain its activity and selectivity for at least five subsequent runs, providing an opportunity for waste biomass valorization.

Summary: One of the most prevalent wastes in the ocean is abandoned, lost, and discarded fishing gears (ALDFGs), which poses a potential mortality risk to all marine creatures. Thermal destruction of ALDFGs, using carbon dioxide as a raw material, can effectively break them down into smaller molecules and neutralize toxic chemicals. Experimental evidence showed that CO2 contributed significantly to the conversion of carbon in hydrocarbons into carbon monoxide (CO).

Summary: Bangladesh is also facing the growing global problem of plastic pollution. Although plastic has many advantages, such as low cost and flexibility, its poor biodegradability and misuse have led to widespread contamination of the environment. This study examines the effects of plastic and microplastic pollution on the environment and human health, and evaluates Bangladesh's knowledge and assessment of plastic pollution in aquatic ecosystems. The study proposes management approaches based on research from industrialized and emerging countries and calls for thorough investigation of plastic contamination in Bangladesh.

Summary: In recent years, there has been an increasing demand for an automated and integrated refining process for biofuels due to the lack of generalized process inspection tools. Real-time product specifications are crucial for batch-wise monitoring in bio-oil upgrading processes to prevent process failure and wasted resources. To address this need, a machine learning model was developed to predict the composition of bio-oil using mass spectra collected from upgraded products. The model was trained using predefined features derived from raw mass spectra and achieved high accuracy with the random forest algorithm. This protocol enables real-time compositional analysis of upgraded bio-oils, facilitates process monitoring, and supports catalyst design and process optimization.

Summary: Surfactant-assisted SrWO4 with scheelite-type structure was prepared and studied for its structural, morphological, and photoluminescence properties. Among the different surfactants used, SDS resulted in SrWO4 particles with spherical morphology. The PL emission of surfactant-assisted SrWO4 showed a bluish-green color around 500 nm, which can be attributed to the luminescence center of WO42- at 284 nm excitation. The presence of surfactant significantly enhanced the PL intensity.

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.
