Recently, interest in eco-friendly techniques for producing antibacterial food packaging films has surged. Within this context, plasma polymerization is emerging as a promising approach for applying degradable antibacterial coatings on various plastic films. This research therefore employs an atmospheric pressure aerosol-assisted plasma deposition technique to create polyethylene glycol (PEG)-like coatings embedding zinc oxide nanoparticles (ZnO NPs) of varying sizes on polyethylene (PE) substrates.

Material And Methods: This was a prospective registry study of patients with STEMI admitted within the first 24 hours of the disease onset. Patients were evaluated and treated according to the current clinical guidelines.
Amorphous mesoporous materials are promising as catalysts for processes involving or forming bulk molecules. In a reaction such as acetone condensation to form mesitylene, an effective catalyst should not only have a developed porous structure but also have active centers of acidic and basic types. The sol-gel approach allows one to obtain titanosilicates with such characteristics.

However, the degradation of these coatings in contact with food remains underexplored. This study employs an aerosol-assisted atmospheric plasma system to deposit polyethylene glycol (PEG)-like coatings with 1 wt% zinc oxide (ZnO) nanoparticles on a polymer substrate.

- Nonthermal plasma (NTP) treatment is a new technology in the food industry but may increase lipid oxidation due to reactive species, particularly as the degree of unsaturation in lipids rises.
- The study examined six different unsaturated lipid methylesters using a nonthermal surface dielectric barrier discharge, analyzing classical oxidation indicators and specific volatile products to assess the oxidation effects.
- Findings indicated that plasma treatment heightened oxidation levels in line with lipid unsaturation, while its long-term effects on oxidative stability were influenced by plasma input gas, sample sensitivity, and antioxidants.
