“…20,21 Due to the incorporation of CNCs, the absorption wavelength related to the stretching vibration of –OH peak of CNC/RC slightly shifted to a lower wavelength (from 3336 cm −1 to 3329 cm −1 ), indicating an increase in hydrogen bonds between hydroxyl groups of RC films and CNCs. 22 As expected, other differences introduced by the addition of CNCs were not obvious, from the low CNC contents deposited on the surface of RC films.

“…All films exhibited a broad peak at 3100−3500 cm −1 attributed to O−H stretching (Figure S1c). 49,50 The neat CNC film presented peaks at 3325 and 3280 cm −1 responding to intra-and intermolecular hydrogen bonding, respectively. 51 The FT-IR spectra of the composite films had peaks similar to those of the neat CNC films, which confirmed that the proximity of the glucan does not destroy the network of intra-and intermolecular hydrogen bonding of CNC particles, and the preservation of hydrogen bonding is conducive to close packing of the glucan backbone with CNCs.…”

The fabrication of biomimetic photonic materials with environmental stimuli-responsive functions from entirely biobased materials is becoming increasingly challenging with the growing demand for biodegradable materials. Herein, the effect of glucan with different molecular weights on the mechanical performance and tunable structural color of iridescent CNC composite films was investigated. The existence of glucan did not influence the self-assembly performance of CNCs, but rather led to an improvement in the mechanical performance, enabling cholesteric CNC composite films with an adjustable structural color. Simultaneously, the iridescent films showed a conspicuous redshift and enlarged initial pitch without obstruction of the chiral structure. In response to environmental humidity, the structural colors of the iridescent composite films can be changed by regulating their chiral nematic structure. In particular, the films demonstrate a reversible structural color change between blue and red at RH between 50 and 98%. The resulting biobased iridescent composite films have potential applications in decorative coating, optical and humidity sensing, and anticounterfeiting.

SummaryHard capsules are a frequently used oral medication delivery form. This study aims to evaluate the potential of tilapia fish gelatine as a suitable material for hard capsules, by analysing various gelatine properties under different extraction temperatures (50 °C, 60 °C, 70 °C, and 80 °C) and extraction periods (6 h and 12 h). The results showed a range of values for the gelatine yield (22‐33% (w/w)), gel strength (141‐ 360 g), molecular weight distribution (140‐300 kDa), and amino acid composition (185‐220/1000 residues). FG70‐12 (296) and FG60‐6 (266) were found to have gel strength between 200‐300 g thus suitable to be used as hard capsule material. Interestingly, the strongest gelatine having 360 g gel strength obtained from FG50‐6 (fish gelatine extracted at 50 C for 6 h) became the essential ingredient for preparing hard capsules because two times dipping was enough to obtain the standard weight and thickness. A slight loss of moisture identified during drying and rapid dissolution (4‐8 minutes) detected from fish gelatine capsule at pH 6.8 or below. Therefore, hard capsules for pharmaceutical applications could be developed from fish gelatine as an alternative gelatine with similar properties as commercial hard capsules and satisfying the pharmacopoeia standard.
