“…A schematic representation of the preparation steps is given in Fig. From the practical viewpoint, this process offers versatile opportunities such as foam-like hydrogels (via fast depressurization), extension to other biopolymers [34], and bactericidal activity of pressurized CO 2 [32]. The carbon dioxide-induced gelation is a novel technique and although the role of pressurized CO 2 in the stiffening of hydrogels is documented [3,21,31], it is not yet fully understood.…”

“…Recently, this method was extended to ionotropic cross-linking by using insoluble carbonates like CaCO 3 as source of cations and alginate as biopolymer [21 -23]. This process does not require any cross-linking agents and can be further extended to other biopolymers such as cellulose and chitosan [34]. In this work, hydrogels prepared by CO 2 -induced gelation served as starting matrices to produce cryogels.…”

However, existing examples are limited to the supercritical drying of the hydrogels, whereas freeze-drying is a widely used alternative remaining unexplored in the combination with CO 2 -induced gelation.…”

This work presents a novel route toward porous scaffolds for tissue engineering and regenerative medicine (TERM) applications. Hybrid cryogels with gelatin, gellan gum, carboxymethylcellulose, and lignin were prepared by a two-step process. Textural properties of the cryogels were analyzed by SEM and micro-computed tomography. The results indicated that rapid freezing retained sample shape and yielded macroporous materials. The mechanical properties of the cryogels were characterized in compression mode. Cytotoxicity studies indicated that the hybrid-alginate cryogels did not present cytotoxicity and have the potential to be used in TERM.

“…было предложено множество методик. Так, производство гибридных аэрогелей, которые включают в себя как неорганическую, так и органическую фазу, встраивание наноча-стиц в матрицу геля, формирование взаимопроникающих сетей и армирование волокнами и наполнителями являются примерами изученных подходов [128][129][130].…”

“…Для получения гибридного альгинат-лигнинового аэрогеля предложено использовать сжа-тый углекислый газ для усиления гелеобразования [128]. Полученные результаты показали, что пористость таких материалов можно контролиро-вать посредством соответствующего изменения состава реакционной смеси и режимов сушки.…”

Aerogels are a class of open nonfluid porous solid materials known for their low density, high specific surface area, and accessible pores. This combination of characteristics makes them highly promising for a wide gamut of applications ranging from thermal and acoustic insulation, catalysts and sensors, adsorbents and absorbents, energy storage, carriers for drug delivery and nutrition, and scaffolds for tissue engineering and regenerative medicine to starting materials for carbon aerogels and porous mixed oxides. Aerogel technology has faced significant bottlenecks in its commercialization, since its discovery in the 1930s, due to limited technical information and processing expertise required for production scaling. This article presents the significant technology developments in the past 10 years, highlighting the paradigm shift in aerogel processing. Lastly, this article invites the reader to envisage and contribute to a new generation of aerogel materials and applications with the fundamental tenets of aerogel production and pore engineering.
