UNSW researchers are exploring how an Australian native coastal plant could help improve the strength and flexibility of biodegradable films.
Researchers developed a solar-spectrum-driven photocatalytic leaching method that uses mild organic acids and a reusable catalyst to extract critical metals from spent lithium-ion battery cathodes under simulated sunlight. The system achieved high leaching efficiencies across several cathode chemistries, while process modeling projected lower environmental impacts and competitive economics compared with conventional recycling routes.
Researchers developed a photolithography-compatible electroforming process that co-deposits mechanically fibrillated cellulose nanofibers with carboxymethyl cellulose to create thin, free-standing microscale structures. The composite films averaged about 4.2 GPa in Young’s modulus, while a 300 nm suspended bridge resonated at 23.34 kHz under vacuum, with modeling indicating residual tensile stress from constrained drying.
A new research project will develop next-generation composites from mycelium to create a sustainable alternative to expanded polystyrene (EPS) in protective and transit packaging.
Colloidal quantum dots are prized for their size-tunable optical properties and solution processability, making them attractive for next-generation displays and lighting.
A delicious chocolate chip cookie all comes down to its bake. A minute too long and you'll be munching on a crunchy cookie.
Mechanical microembossing altered the surface structure and near-surface PLA/PBAT distribution of 70/30 blend films while preserving previously reported water-repellent behavior. Under controlled incubation with Bacillus subtilis, patterned films showed greater biodegradation-related mass loss than untreated films, with the largest loss reaching 7.50% after 115 days.
Researchers showed that recycled PET can be combined with 10 wt% waste cellulosic fibers to produce usable composites, provided processing conditions limit thermal degradation. Performance depended strongly on the PET feedstock, with the TiO2-containing grade showing the smallest losses in molecular weight, strength, and ductility.
The VERSO project, led by AIMPLAS, the Plastics Technology Centre, promotes digitalization and the circular economy in the packaging sector through the application of the Digital Product Passport (DPP) and the validation of reuse systems.
Researchers used ultrasound-assisted carbonation to control water confinement in fresh cement paste, producing a highly refined pore network with 96.8% of pores below 200 nm. The resulting paste combined high specific compressive strength, greater high-frequency sound transmission loss, strong strength retention after water saturation, and cumulative CO2 uptake of 7.11% of cement mass after 28 days.
