Human ingestion of microplastics (MPs) is common and inevitable due to the widespread contamination of food items, but implications on the gastric digestion of food proteins are still unknown. In this study, the interactions between pepsin and polystyrene (PS) MPs were evaluated by investigating enzyme activity and conformation in a simulated human...
Over the last several years, the number of concepts and technologies enabling the production of environmentally friendly products (including materials, consumables, and services) has expanded. One of these ways is cradle-to-cradle (C2C) certified(TM). Life cycle assessment (LCA) technique is used to highlight the advantages of C2C and recycling as ...

Catalyst in the process on glycolysis of poly (ethylene terephthalate) (PET) wastes is a significant critical factor, which determine the efficiency and the cost of PET degradation. In this study, a kind of transition- metal-substituted polyoxometalates (POMs) Na-12 [WZnM2(H2O)(2)(ZnW9O34)(2)] =(M = Zn2+, Mn2+, Co2+, Cu2+, Ni2+) which have a sandwi...

This work reports measurements of effective oxygen diffusion coefficient in raw cork. Kinetics of oxygen transfer through cork is studied at 298 K thanks to a homemade manometric device composed of two gas compartments separated by a cork wafer sample. The first compartment contains oxygen, whereas the second one is kept under dynamic vacuum. The p...
Oxygen is one of the most important factors determining the aging potential of bottled wine, and oxygen diffusion into bottled wine is extremely dependent on the sealing effectiveness of the closure. A nondestructive colorimetric method was developed to measure oxygen diffusion from 1 to 9.8 mg/L during the postbottling period. This method was used...

For further improvement of PET-market two items are essential: Development of high-barrier materials (e.g. for sensitive applications like beer-bottles) and technological improvement of PET-recycling. Because of the insufficient elimination of contaminants there was no high-value creation for the mixed and contaminated PET-fraction from post-consum...
The following lectures were given at the experts' forum: Constitution and properties of high-performance thermoplastics (H.Muenstedt); Engineering plastics in comparison (G.Blinne); High-temperature thermoplastics (F.Zahradnik); Polypropylene for engineering applications (M.Gahleitner); Injection molding technology for high-performance thermoplasti...
