“…In two recent reviews, as an alternative, Tian et al [ 19 , 20 ], reprising what was extensively described by Yao in 2019 [ 22 ], proposed a categorization more focused on the “final structure” and on the role of the cyclodextrin in the construction of the polymer. Similarly, Liu et al, in a recent and comprehensive review [ 35 ], divided cyclodextrin polymers into four categories, according to their structures (CD-based polyrotaxanes, grafted CD polymers, crosslinked CD polymers and CD-based star polymers). This division, in our opinion, takes into account the final structure but does not immediately clarify the presence of bonds or the presence of supramolecular forces.…”

Cyclodextrins (CDs) are a good alternative to reduce or enhance different biomolecule characteristics and have demonstrated great results in food science. However, CDs present intrinsic limitations that can be solved by derivative synthesis. This review represents a survey of the state of the art of CD-based materials and their uses in food science. A deep review of the structure is carried out and different groups for ordination are suggested. After that, different applications such as cholesterol complexation or its use as sensors are reviewed. The derivatives show novel and promising activities for the industry. A critical perspective of the materials suggests that they might not present toxicity, although more studies are required. These points suggest that the research in this field will be increased in the following years.

“…13 The exterior portion with ample hydroxyl groups can not only endow the CDs with great hydrophilicity but can also be modified with functional groups to adapt to the different physiochemical environments. [14][15][16][17][18] The interior cavity, which is the slightly nonpolar cavity of CDs in an aqueous environment, is more prone to encapsulating guest molecules with less polarity, and this makes CDs an ideal platform to deliver hydrophobic drugs. [19][20][21][22] Unique structures prepared by CDs, such as rotaxanes and polyrotaxanes, have been widely applied in biomedical applications as well.…”

“…Boron nitride (BN) aerogels are the ultralight ceramic materials assembled by BN nanoscale building block [1][2][3], and they exhibit low density, large specific surface area, excellent thermal/electrical insulation, outstanding chemical stability and desirable high-temperature oxidation resistance, which offer considerable advantages for various applications under extreme conditions [3], such as high-temperature superinsulation, thermal protection and environmental cleaning in harsh environment (acid, alkali), while the polymeric and carbonaceous aerogels could collapse easily with performance damping [4][5][6][7]. During the process of BN aerogels, how to construct porous network with nanoscale skeleton using BN nanoscale building blocks is of great significance for the mainstay of various applications [1].…”

Boron nitride (BN) aerogels, composed of nanoscale BN building units together with plenty of air in between these nanoscale building units, are ultralight ceramic materials with excellent thermal/electrical insulation, great chemical stability and high-temperature oxidation resistance, which offer considerable advantages for various applications under extreme conditions. However, previous BN aerogels cannot resist high temperature above 900 °C in air atmosphere, and high-temperature oxidation resistance enhancement for BN aerogels is still a great challenge. Herein, a calcium-doped BN (Ca-BN) aerogel with enhanced high-temperature stability (up to ~ 1300 °C in air) was synthesized by introducing Ca atoms into crystal structure of BN building blocks via high-temperature reaction between calcium phosphate and melamine diborate architecture. Such Ca-BN aerogels could resist the burning of butane flame (~ 1300 °C) and keep their megashape and microstructure very well. Furthermore, Ca-BN aerogel serves as thermal insulation layer, together with Al foil serving as both low-infrared-emission layer and high-infrared-reflection layer, forming a combination structure that can effectively hide high-temperature target (heated by butane flame). Such successful chemical doping of metal element into crystal structure of BN may be helpful in the future design and fabrication of advanced BN aerogel materials, and further extending their possible applications to extremely high-temperature environments.
