Summary: This review discusses the challenges of thermal degradation in antioxidant compounds (AC) in the food industry and highlights various formulation strategies to improve their thermal stability. The use of technologies like emulsion, cyclodextrin, liposome, hydrogel, solid lipid nanoparticles, and natural deep eutectic solvent shows promise in preserving AC from thermal degradation.

Summary: This study utilizes the primary amide side-chain of acrylamide copolymers as an isocyanate surrogate. The isocyanate is generated through an electrochemical Hofmann rearrangement under mild conditions, resulting in the formation of O-alkyl carbamate side-chains in alcohol solvents. This represents a novel strategy for modifying amide-functionalized (co)polymers.

Summary: In this study, a bio-based polyether-polyurethane foam was successfully prepared using the prepolymer method. The foam showed good chemical stability with a weight loss of only 12% after soaking in a sodium hydroxide solution for 30 days. Enzymatic hydrolysis using cholesterol esterase was found to be more favorable than hydrolysis with NaOH, with a weight loss of 24%. The use of BHMF as a renewable chemical was crucial for the enzymatic degradation assay, and the foam also exhibited significant biodegradation in soil burial test after three months. This study highlights the potential of sustainable resources in producing biodegradable materials.

Summary: By applying a patented process, infusions without any kind of waste were prepared using all parts of edible plants and asparagus varieties. The polyphenol content and antioxidant activity of the infusions were measured, and it was found that Malva sylvestris L. and Asparagus officinalis L. var. Early California powders had higher polyphenol content compared to Calendula officinalis L. and Asparagus officinalis L. var. Vegalim. Further analysis is underway to compare these infusions with commercial ones.

Summary: In this work, a theoretical investigation was conducted to understand the underlying processes of chabazite supported fuel treatment and improve thermal stability. The study revealed various molecular interactions between zeolite and oxygenated species, and demonstrated that observed enthalpy changes can be used as a predictor for the removal of contaminants by zeolite.

Summary: Agricultural application is the main source of antibiotic consumption worldwide. Veterinary antibiotics, poorly metabolized by animals, end up in agricultural waste and are increasingly subjected to thermal treatment. However, there is a lack of research on the thermal decomposition mechanisms and products of these antibiotics.

Summary: The five synthesized polyhydroxybenzophenones exhibited significant antitumor and antioxidant activities, with compounds 1-3 and 5 showing promising potential for further structural modification. Compounds 1 and 2 demonstrated stronger cytotoxicity against hepatocarcinoma SMMC-7721 cells than cisplatin, while compounds 1, 2, and 3 exhibited stronger antioxidant activity than trolox. The antioxidant mechanism and strength of all compounds were further verified using computational chemistry.

Summary: Natural deep eutectic solvents (NADES) composed of choline chloride, sucrose, fructose, glucose, and xylose were used to extract antioxidants from sea knotgrass in this study. The NADES extracts showed higher antioxidant activity compared to conventional solvents, with ChCl:fructose being the most efficient in the radical scavenging assay. The phenolic composition of NADES extracts was less complex but contained similar proportions of major antioxidants like flavonols and flavan-3-ols compared to conventional extracts.

Summary: This study introduces a rapid and efficient system to adapt commercially available polymers for melt electrowriting (MEW) for the fabrication of micro-fibrous scaffolds. By pre-treating PLCL at 150 degrees C for 24-48 h, it can be printed into scaffolds at 110 degrees C with fiber diameters of 14-40 μm, becoming the first low-temperature MEW scaffolds of its kind. This approach requires no modification of the MEW machine and can be readily adopted by any MEW user with minimal polymer manipulation.

Summary: This study investigates the swelling effects of O-rings in different fuels and aromatic species, with Jet-A1 showing the highest swelling effect. Prepared seals exhibited a lower swelling rate compared to non-prepared seals. Results suggest that the percentage of aromatics in fuel directly influences the rate of swelling.

Summary: Aviation is a key player in the global economy, yet it contributes to climate change through emissions like CO2. Despite efforts to reduce its impact through policies, regulations, and research, it is unlikely that aviation will meet emission goals aligned with the Paris Agreement, even with technological advancements and sustainable fuels.

Summary: This report introduces the establishment of distributed databases for managing and integrating aviation fuels. With the recent accumulation of significant data for alternative fuels, a scalable, Json based format is proposed for storing fuels data. A joint database has been developed, containing data from various research programs and sources, which can be used for multiple purposes. Collaboration and further development opportunities are encouraged in the wider fuels community.
