Under the combined contributions of two-photon absorption (TPA), TPA-induced excited state absorption or three-photon absorption (3PA), both compounds exhibit broadband reverse saturation absorption, which extends to 1550 nm.

Here, we prepared a novel chitosan-based green active composite film, employing chitosan nanoparticles encapsulating gallic acid as nanofillers. The interfacial interactions between the nanoparticles and chitosan matrix were found to significantly enhance the mechanical properties and barrier properties of the composite film. Moreover, the integration of gallic acid-loaded nanoparticles substantially improved the antimicrobial and antioxidant activities of the composite film. These improvements are crucial for inhibiting the proliferation of food-borne microorganisms and the oxidation of lipids, thereby preserving the quality and safety of foods. Freshness preservation experiments have demonstrated that this composite film could effectively mitigate the quality degradation of crayfish meat during storage, thereby verifying its potential application in the field of food packaging.

This challenge has sparked tremendous interest among scientists, driving the pursuit of innovative methods to vitrify non-meltable ZIFs for various applications. Herein, we show a universal approach for synthesizing glasses and foams from non-meltable and porous ZIFs, such as 2D ZIF-7 and 3D ZIF-8, which stand as the most promising porous materials of the ZIF family. This approach is based on the combination of liquid-mediated sequential structure perturbation and post-heat treatment, yielding a variety of highly microporous ZIF foams like glass. The synthesized ZIF foams exhibit superior gas adsorption capacities compared to melt-quenched ones. The as-fabricated membranes based on ZIF foams demonstrate ultrahigh H<small>₂</small> permeance and good H<small>₂</small>/CH<small>₄</small> selectivity. In comparison to the melt-quenching technique, our structural perturbation strategy allows for the synthesis of a significantly greater quantity of glasses and foams from a single batch.
