Here, we report a self-propelling system in which a millimeter-sized tube is confined within a hydrogen peroxide droplet on a superhydrophobic surface. The tubes are synthesized <i>via</i> chemical garden self-assembly and catalyze the decomposition of the peroxide to water and oxygen gas. The resulting droplet-tube cell exhibits diverse dynamic behaviors, including propeller-like spinning, orbital rotation, and long-range translational jumps, driven by the asymmetric growth and bursting of internally generated gas bubbles. These motions are sensitive to hydrogen peroxide concentration, which governs both the internal gas production rate and the system's active lifetime.

A polyimide-coated fiber for solid-phase microextraction (SPME) was then fabricated using a simple dipping method.

The developed polyimide-coated fiber-based SPME method, coupled with gas chromatography-flame ionization detection, exhibited low limits of detection (0.11–1.23 μg L<small>⁻¹</small>) and a wide linear range (1–500 μg L<small>⁻¹</small>) for polycyclic aromatic hydrocarbons in water samples. The method demonstrated excellent repeatability, with single-fiber repeatability ranging from 2.9% to 6.9% and fiber-to-fiber reproducibility between 3.9% and 11.5%. The recoveries of the analytes were between 82.7% and 107.2%. Additionally, the fiber exhibited outstanding durability, maintaining its extraction performance after more than 150 uses.

The birth defects and fragile lattice result in the sluggish Li⁺ diffusion kinetics and unfavorable structural degradation. Moreover, lattice strain, mechanical failures, surface reconstruction, and interfacial side reactions accelerate the decay process. Here, a proof-of-principle study of the lattice plainification (LP) strategy in a high-nickel NCM cathode is reported. The introduction of Al and Zr in transition metal layers by a wet chemistry and calcination method enables the simplification of the complex lattice structures to obtain an order phase and repair the various defects of NCM, thereby enhancing the lithium-ion transport. The modified LP-NCM exhibits a high initial discharge capacity of 157.3 mAh g^-1 with a capacity retention of 81% after 300 cycles at a 5C rate, significantly outperforming the pristine counterpart (50.9%). The LP-NCM/Gr pouch cells presented impressive cycling performance, achieving 80% capacity retention over 1000 cycles at 1C, which far surpasses the performance of the pristine NCM. Our method eliminates the rocksalt and disordered phases, and suppresses oxygen, lithium, and transition metal vacancies, as well as Li/Ni mixing. LP-NCM after cycling exhibits nanopores rather than cracks of pristine NCM. Our investigations reveal that the lattice plainification design approach flattens and toughens up the crystal lattice, which contributes to robust structural stability and improves the structure degradation, mechanical failures, and gas release.

In response, a market of anti-wrinkle formulations has emerged that claims to restore skin's youthful appearance. However, the biomechanical mechanisms behind this wrinkle reduction remain poorly understood due to the complex mechanics of multi-layer, furrowed structures. Using a combination of digital microscopy and thin-film mechanics techniques, we show that polymers contained in anti-wrinkle formulations form contracting films on the skin surface. This contraction leads to the appearance of fewer wrinkles in two synergistic ways. First, the amplitude of large wrinkles is reduced as the skin surface tries to match the polymer's reduction in length. Second, the skin-now in compression-microbuckles. These microbuckles diffusely reflect light, helping mask larger wrinkles. Using a simplified theoretical model, we explore how the mechanical properties of the skin and polymer alter both processes.
