Summary: Due to its hierarchical structure, wood can generate electricity from mechanical energy through piezoelectric behavior. This study presents a scalable method to synthesize wood/ZnO composites with multilayered ZnO morphologies for efficient mechanical energy conversion. The synthesis process involves fabricating charged wood templates, infiltrating precursors, and hydrothermally growing ZnO, resulting in controlled ZnO morphologies and maintaining the hierarchical structure. Stereo-digital image correlation reveals that the homogeneous distribution of multilayered ZnO enhances piezoelectric performance. The wood/ZnO composite exhibits an output voltage of 1.5 V and an output current of 2.91 nA under periodic mechanical compression (8-10 N) for 300 cycles. The scalable synthesis strategy and excellent piezoelectric performance are crucial for the design of advanced wood nanocomposites for sustainable and efficient energy conversion systems.

Summary: This paper presents a method to generate hierarchical wrinkles in two-dimensional electronic materials, allowing for spatial control over adjacent wavelengths. A rigid fluoropolymer mold was used to pattern sacrificial polymer skin layers on various 2D materials, resulting in 2D material wrinkles with wavelengths proportional to the local skin thickness. The generation of second-generation wrinkles was also demonstrated by applying subsequent cycles of polymer skin coating, strain relief, and removal. This area-specific hierarchical wrinkling enables engineering of the local properties of 2D materials and their heterostructures.

Summary: The use of deagglomerated nanodiamond particles suspended in PDMS has shown significant electrorheological effects, with hydrogenated nanodiamonds exhibiting the most powerful effect. Even at low concentrations, these suspensions demonstrate high yield stress and excellent sedimentation stability. The relationship between yield stress and electric field follows a power law, indicating a conduction mechanism at play. The type of functional groups on the nanodiamond surface plays a crucial role in the rheological behavior of the suspensions.

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.
