Summary: In this study, hardwood and softwood lignins were used to produce bio-polyols for the synthesis of rigid and elastic polyurethanes. The reaction parameters were optimized using response surface methodology, and the effects of catalyst concentration, temperature, and Polyethylene glycol/Glycerol weight ratio on the properties of bio-polyols were evaluated. The optimal reaction conditions for rigid polyurethanes were similar for both lignins, while the conditions for elastic polyurethanes varied depending on the lignin used. The bio-polyols obtained at optimized conditions were fully characterized.

Summary: Plasmonic nanoparticles enhance the photocatalytic performance of semiconductor nanoparticles through light scattering, light concentration, hot electron injections, and plasmon-induced resonance energy transfer. They extend the absorption range and increase the quantum yield of electron-hole generation. However, the lack of systematic design for plasmonic-semiconductor nanoparticle conjugation is a common issue in the reviewed papers. This review emphasizes the importance of rational optical design and provides a useful guideline for researchers interested in enhancing photocatalytic activity and understanding plasmon-enhanced phenomena.

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.
