The GBC is characterized using Thermo Gravimetric Analysis (TGA) and Scanning Electron Microscopy (SEM), and different proportions of fire retardant components are studied for their heat shielding effect and morphology. The development of predictive models for the degradation of such materials is essential due to the expensive and high heating rates required for industrial-scale evaluation.

Summary: Biochars derived from agricultural wastes were modified by manganese ferrite (MnFe2O4) co-precipitation and used as adsorbents for the removal of Cu(II) ions from water. The MnFe2O4-biochars exhibited rapid adsorption kinetics and significantly enhanced adsorption capacities. Complexation reactions involving carboxyl and hydroxyl groups in pristine biochars, as well as Mn-O and Fe-O groups in MnFe2O4-biochars, were identified as the principal adsorption mechanisms. The regenerated MnFe2O4-biochars could be reused for three cycles with a decline in maximum adsorption capacities.

Summary: Considering the increasing health concerns, urban population tends to adopt a healthy lifestyle and incorporate nutritional food supplements to mitigate common health risks. The consumption of omega-3 and omega-6 PUFAs is on the rise, thus alternative commercial production methods are being developed. Microbial sources are emerging platforms to meet the global demand for omega PUFAs. Marine oleaginous protist Aurantiochytrium sp. has been identified as a potential source for substantial production of DHA and SFA. The objective of this research was to enhance PUFA yield by optimizing glucose concentration and nitrogen ratio. The maximum lipid and DHA yield and content were achieved at 30 g/L glucose, while the relative PUFA content was highest at 10 g/L glucose, with remaining SFA potentially usable for biodiesel.

Summary: Wetting and dewetting behaviors of Ag droplets on different Mo surfaces were studied using molecular dynamics simulations. Diffusion energy barriers of Ag droplets on the surfaces were analyzed, revealing the presence of precursor films and adsorption layers. Alloying improved the wetting ability of the Mo(111) surface, which had significant precursor films. The fastest dewetting rate was observed on the surface with the highest adsorption layer density. The same molecular kinetic theory model applied to both wetting and dewetting processes, and higher temperatures reduced the time to reach equilibrium.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
