The Al<sub>2</sub>O<sub>3</sub> coating on the CsPbBr<sub>3</sub> surface is realized by in situ oxidation of trimethyl aluminum (TMA), which passivated the surface defects while blocking the intrusion of water and oxygen. The EVA film is formed by a solution method, which can further block the water and oxygen, and form the flexible composite with perovskite CsPbBr<sub>3</sub> nanocrystals with enhanced stability toward water and heat. After soaking for 360 h and heating for 5 h, the photoluminescence (PL) intensity is higher than that without passivation. The polymer EVA packaging strategy provided CsPbBr<sub>3</sub> with excellent extensibility and flexibility at 100% and 200% tensile rates, the PL intensity remains 91% and 88% of the initial intensity, which returns to the initial value after stretching.

There is great interest both in fundamental science and technical applications to better understand and technically control these forces. In this work, the influence of five different self-assembled bio and organic monolayer thin films on the Casimir force between a plate and a sphere is experimentally investigated. It is found that the films, despite being a mere few nanometers thick, reduce the Casimir force by up to 14%. Spectroscopic data indicate a broad absorption band whose presence can be attributed to the mixing of electronic states of the underlying gold layer and those of the molecular film due to charge rearrangement. Using Lifshitz theory, it is calculated that the observed change in the Casimir force is consistent with the measured change in the effective dielectric properties. The nanometer-sized molecules can penetrate small cavities, and cover any surface with high efficiency. This process seems compatible with current methods in the production of micro-electromechanical systems (MEMS), which cannot be miniaturized beyond a certain size due to ‘stiction’ caused by the Casimir effect.

Therefore, a method is proposed here for generating, controlling, and characterizing the morphology of hydrogel foams from liquid foam templates: Using the example of Alginate-CaHPO<sub>4</sub>-based hydrogel foams, a highly controllable foaming process is provided by bubbling nitrogen through nozzles into the solution, which produces hydrogel foams with millimeter-sized bubbles. A rheological characterization protocol of the foam's constituent material is first implemented and highlights the impact of the initial liquid foam properties and of the competition between the solidification kinetics and the foam aging mechanisms on the resulting morphology. X-ray tomographic characterization performed on solidifying and solidified samples then demonstrates that by controlling the temporal evolution of the foam via its formulation, it is possible to tune the final morphology of the alginate foams.
