Summary: Through optimizing the size and alignment of inorganic platelets and improving the interfacial interaction with polymers, intensive studies on bioinspired multilayer composites have led to the development of a new strategy of polymer chain orientation to enhance mechanical properties. By enhancing the stiffness and alignment of multiple polymer chains, a large enhancement in mechanical properties, including Young's modulus, tensile strength, and toughness, is achieved in bioinspired multilayer films consisting of oriented sodium carboxymethyl cellulose chains and alumina platelets. The increased chain orientation induces a failure mode transition in the multilayered films, leading to improved stress transfer and a highly effective increase in modulus, strength, and toughness.

Summary: In this study, two metastable reconstruction states with distinct stacking orders and strain soliton structures were identified in small-angle twisted graphene using conductive atomic force microscopy. The switching mechanism between these two states was found to propagate spontaneously in a domino-like fashion. The fine structure of the bistable states is critical for understanding the unique properties of van der Waals structures with tiny twists.

Summary: Janus engineering of transition metal dichalcogenide monolayers induces significant current-induced spin polarization, which can be effectively controlled by external strain. The Rashba spin-orbit coupling and hexagonal warping of the valence bands play a key role in determining the spin polarization. The Janus WSSe monolayer shows potential for flexible two-dimensional spintronics devices.

Summary: The objective of this study was to investigate multiphase systems based on blends of polylactic acid (PLA) and polyamide 11 (PA11), ranging from blends to multilayers. By using reactive extrusion, PLA/PA11 blends compatibilized with a multifunctionalized epoxide, Joncryl, were obtained. The thermal, morphological, rheological, and mechanical behaviors of these materials were studied. The results revealed that the addition of Joncryl as a compatibilizer significantly reduced particle size and interfacial tension, resulting in ductile behavior in the tensile properties. Furthermore, the effects of interdiffusion and diffuse interphase formation on structure, rheology, and mechanics of compatible multilayered systems fabricated with forced-assembly multilayer coextrusion were investigated based on these findings. This study contributes to a deeper understanding of the interfacial properties, such as rheological, mechanical, and morphological behaviors, and their control in multilayer polymers produced by coextrusion, enabling their use in advanced applications.

Summary: When liquid alkane droplets are placed on a surfactant solution surface, a mixed monolayer is formed as alkane molecules penetrate into the surfactant-adsorbed film. Cooling the mixed monolayer results in a thermal phase transition from a two-dimensional liquid to a solid monolayer. The distribution of counterions in the mixed monolayer is affected by this surface phase transition, as verified by total-reflection XAFS spectroscopy and surface quasi-elastic light scattering. Understanding these effects is important for the future applications of colloidal systems involving surfactants and alkane molecules, such as foams and emulsions.

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.
