Summary: The study demonstrated the use of pineapple peel extract as a natural antioxidant in the fabrication of PVOH and corn starch films. The addition of PPEs improved the antioxidant properties, enhanced the thermal stability, and increased the elongation at break of the films. These findings suggest that PVOH/ST/PPE films could be a promising material for producing active biodegradable packaging to preserve food products from oxidation reactions.

Summary: In this study, natural plant polyphenol-proanthocyanidin (PAC) and layered clay-layered double hydroxides (LDHs) were incorporated into poly(vinyl alcohol) (PVA) coatings to create PAC/PVA and PAC functionalized LDHs (LDHs@PAC-Cu)/PVA dual active coatings, which were then applied to PLA base films to develop PLA active films. The results demonstrated that the addition of LDHs@PAC-Cu significantly enhanced the active packaging functions and gas barrier properties of PLA films. Furthermore, the antioxidant and antibacterial properties of PLA films reached high levels, and the shelf life of pasteurized milk was extended. Active substances release test showed that LDHs@PAC-Cu not only delayed the release of active substances in the early stage, but also supplemented their release in the later stage, effectively prolonging the shelf life of food. Therefore, PLA active films have great potential in active food packaging.

Summary: The mechanical performance of thermoplastic bulk samples obtained from different types of wheat flours was evaluated. Bran presence increased the strength and reduced the elongation at break of the thermoplastics. The grinding level also had an effect on the properties, with finer grinding resulting in higher strength and lower elongation. The presence of bran affected the exposure of starch granules to the plasticizer.

Summary: In recent years, a wide range of high temperature materials have been developed for use as Thermal Protection Systems (TPS). Graphite, a carbon-based material, has been widely used as a TPS material but it has limitations in terms of mechanical properties and resistance to thermal shocks. To overcome these limitations, carbon fibers are introduced into a carbon matrix to produce Carbon/Carbon Composites (CCCs). In addition, research has been conducted on alternative matrices such as phenolic resins, cyanate esters, bismaleimides, and benzoxazines in combination with carbon fibers. This paper provides a review of the current challenges in manufacturing high char yield matrices and carbon fibers derived from alternative precursors. The possibility of producing carbon fibers from precursors other than PAN, Rayon, and Pitch, as well as non-oil based phenolics, bismaleimides, cyanate esters, and benzoxazines, is discussed.
