Summary: This research examines the dynamics of dependence and causality between the S&P Kensho Clean Energy (CE) and Cleantech (CT) indices and two green bond indices, as well as four Islamic bond indices. The study finds that the dependence of CE and CT on Sukuk and green bond indices strengthens in the long and medium term, particularly in normal or bearish market conditions. AA- and A-rated Sukuk indices and Green Bond Select (GBS) indices exhibit stronger dependence with CE and CT compared to other instruments. Furthermore, causality is predominantly observed from Sukuk and bond indices to CT and CE in the frequency domain.

Summary: We present a strategy to tune the catalytic behavior of the pincer-Co catalyst by investigating the effect of partners such as (18-crown-6)K+, W(CO)(3), and W(PMe3)(3) on the nitrile hydroboration reaction. The partner's influence on the cobalt center's electron-richness and the donor ability of the pincer ligand is revealed through pi-coordination. These findings suggest a notable partner effect that can be explored by experimentalists to tune the reactivity of catalysts without ligand modification.

Summary: An ecofriendly resorcinol derivative, dimethyl-4,6-dihydroxyisophthalate (DDIP), is investigated as an anticorrosion agent for low carbon steel in hydrochloric acid solution. It is found that the DDIP compound effectively reduces the corrosion rate of the steel, with a higher mitigation efficiency at higher dosages. The compound's adsorption on the steel surface follows Langmuir's concept and is a combination of physisorption and chemisorption. The study also reveals the formation of a protective film on the steel surface in the presence of the DDIP inhibitor, confirmed by various characterization techniques. Quantum characteristics further support the potential of the DDIP compound as a promising inhibitor.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
