Collagen fiber and polyvinyl alcohol barrier films for food packaging
Biodegradable, heat-sealable films combining collagen fiber with polyvinyl alcohol (PVA) for food packaging applications. Validated at lab scale (TRL 4) on sliced meats, fresh meat, and strawberries, with demonstrated ox...
Pressure-driven shoe cooling system using thermodynamic refrigeration principles
A novel footwear technology that leverages foot pressure to passively cool shoe interior air through a miniaturized refrigeration cycle. The system combines a pressurized heel chamber with relief nozzles that expand air ...
Botanical extract-based herbicides for grass weed control in agricultural crops
A research team at Universidade Federal de Santa Maria has developed aqueous botanical extracts from five plant species that control grass weeds in crops such as rice, corn, and soybean. Laboratory and greenhouse tests s...
Biodegradable chitosan and gum arabic films enhanced with ionic liquids from essential oils
Introducing biodegradable films made from chitosan and gum arabic, enhanced with ionic liquids derived from natural sources like eugenol and cinnamic acid. These films offer improved microbiological properties for food a...
Biochemical herbicide targeting weeds
UFSM is developing a biochemical herbicide derived from the fungus Fusarium fujikuroi as a sustainable alternative to synthetic chemicals like glyphosate. The project aims to provide an effective, environmentally friendl...
