Article Abstract
Silica aerogels are highly porous materials known for their low density and extensive surface area, making them ideal for applications in thermal insulation, catalysis, and environmental remediation. This study investigates the structural changes of functionalized hydrophobic silica aerogels used as carriers of the LCC ICCG enzyme. The aerogels were synthesized using the sol-gel method, with trimethylethoxysilane (TMES) as a functionalizing agent to enhance hydrophobicity. The enzyme-encapsulated aerogels were characterized using hyperpolarized Xe NMR, Si NMR, nitrogen sorption analysis, TEM, contact angle measurements, and FT-IR spectroscopy to evaluate their structural and chemical properties. The results confirmed successful encapsulation of the enzyme, as indicated by changes in the pore structure and network morphology. These findings demonstrate that functionalized silica aerogels can effectively support LCC ICCG immobilization, offering a promising approach for plastic degradation applications.

The application of aerogels in textiles is limited because their poor moisture permeability and mechanical properties. Aerogel flowers with down-like structures for clothing filling are prepared by laser cutting bacterial cellulose. The nanoporous structures of the aerogels maintained excellent heat preservation performance, and the large pores between flowers provided a channel for water vapor transmission.

Bionic synthesis technology has made significant breakthroughs in porous functional materials by replicating and optimizing biological structures. For instance, biomimetic titanium dioxide-coated carbon multilayer materials, prepared via biological templating, exhibit a hierarchical structure, abundant nanopores, and synergistic effects. Bionic mineralization further enhances microcapsules by forming a secondary inorganic wall, granting them superior impermeability, high elastic modulus, and hardness.

ZrO aerogels are renowned for their exceptional stability and high positive charge, positioning them as promising candidates for various applications. However, the inherent frangibility and contractibility of ZrO aerogels pose significant challenges in processing and drying intactly. In this study, we introduce a novel approach to fabricate 3D-printed ZrO-based aerogels through electrostatic attraction-assisted cogelation process, utilizing a silica reinforcement and rheological adjustment strategy.

The trade-off between sensitivity and detection range has limited the performance of flexible pressure sensors, hindering their deployment in advanced human-machine interfaces and precision healthcare monitoring. Inspired by the ion-mediated electrogenesis of electric eels, we report a bioinspired iontronic pressure sensor (IPS) that overcomes this bottleneck by coupling MXene-functionalized electrodes with a hierarchical silica aerogel/ionic liquid (ILA) dielectric. This architecture enables pressure-driven, reversible ion migration within the porous dielectric and enhances electrical double-layer (EDL) formation at the electrode-dielectric interface.

Traditional high-density thermal protection systems (TPSs) limit the maneuverability of hypersonic vehicles while lacking stealth capabilities. In this work, we propose a strategy to integrate electromagnetic wave absorption and thermal protection in an aerogel composite by introducing a PEDOT:PSS heterointerface via ethanol-assisted gel impregnation. Ethanol also functions as secondary doping, enabling tuning of the electromagnetic parameters of the aerogel by adjusting the doping level.
