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.
Researchers developed a light-responsive spiropyran and multi-walled carbon nanotube hybrid that accelerated Bisphenol A degradation under simulated solar irradiation and generated reactive oxygen species linked to pollutant breakdown. The catalyst also reduced cytotoxicity in MCF-7 cell tests and retained its crystalline structure across four reuse cycles, though its degradation efficiency declined gradually.
A research team led by Dr. Kyung-Soo Kang and Dr. Hyun-Jun Lee from the Hydrogen Energy Research Division of the Korea Institute of Energy Research (KIER) has developed novel Ni/Co-based heterostructure water electrolysis electrodes that deliver superior hydrogen production efficiency compared to conventional noble-metal electrodes.
