Summary: This study introduces a hydrophobically modified bacterial cellulose nanofibrils (BCNF)-stabilized Pickering emulsion system, which can limit the influx of metal ions through the interface. The C18 alkyl chain-grafted BCNF (C18BCNF) can readily associate to generate a resilient thin membrane at the oil-water interface regardless of the type of oil, essential for the production of stable emulsion drops. By manipulating the grafting amount of the C18 alkyl chains and controlling the C18BCNF concentration, the viscoelasticity of C18BCNF-armored Pickering emulsion can be feasibly tuned.

Summary: Pickering emulsions, stabilized by adsorbed particles, have high potential for application in the food industry. They provide more benefits compared to emulsions stabilized with surfactants, such as lower susceptibility to coalescence and possible encapsulation and controlled release of functional compounds. Additionally, they can be used for fat reduction and encapsulation of sensitive compounds.

Summary: The study developed foam-based microwave absorbers with excellent photo-thermal conversion and thermal insulation properties using the oil-in-water Pickering emulsion gelation approach combined with freeze-drying. The hybrid foam consisted of cellulose nanofibrils and polylactic acid as three-dimensional skeleton, with carbon nanotubes and Fe3O4 nanoparticles homogeneously incorporated to form a conductive network with hetero-interfaces. The foam exhibited an optimal reflection loss value of -65.14 dB and high photo-thermal conversion performance, with superior thermal insulation compared to commercial foams. This research may provide a promising approach for developing ultralight and high-performance microwave absorbers with multifunctional applications.

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.
