Summary: This study simulated the turbulent flow of a nanofluid in a channel and investigated the effects of factors such as fin shape and nanoparticle shape on the heatsink temperature and pressure drop. The results showed that increasing velocity leads to lower heatsink temperature, and using brick-shaped nanoparticles and circular fins provides the best cooling performance. Additionally, circular fins and brick-shaped nanoparticles require less pressure drop compared to other cases.

Summary: Waste-consuming green alkali-activated materials (AAM) can serve as a sustainable alternative to traditional Portland cement. However, the use of activators in AAM has posed challenges due to their high costs, embodied energy, and carbon dioxide emissions. This paper provides a comprehensive review on sodium system activators (SSA), classifying them into three categories and discussing their advantages and disadvantages, source and preparation mechanisms, mechanical properties, cost, and environmental impact. The study concludes that green commercial activators show the most potential for development and offers suggestions for promoting the use of SSA in AAM.

Summary: The study showed that dGN with N and O atom as the electron acceptor for C atom had higher specific activities in terms of electrochemical surface areas, while S-doped dGN exhibited low activity possibly due to the low bond polarity between C and S atom. The physical adsorption of hydrogen peroxide on the carbon catalysts limited the reaction kinetics, further influencing the reaction efficiency.

Summary: In this study, core-shell PdAu octahedrons (Oct), PdAu truncated octahedrons (t-Oct), and PdAu nanocubes (NC) were successfully synthesized, and their specific activities in glucose oxidation reaction (GOR) and glucose sensors were systematically studied. The kinetic studies showed that the specific activities (S-A1) of the nanocrystals followed the order of t-Oct > Oct > NC, indicating that glucose easily bonded to t-Oct with the (211) facet. However, the specific activity (S-A2), estimated by the moles of electrons over ECSA, showed the order of Oct > t-Oct > NC. The facile electron transfer of GORs occurred via PdAu Oct with an electron-rich Au shell. Additionally, PdAu Oct demonstrated high recoveries when used as a glucose sensor for energy drinks.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
