Abstract. The mechanical properties of polymer composites based on polylactide vary significantly over a wide range values. It has been established that photodegradation low-density polyethylene – blends occurs both in the amorphous and crystalline phase PLA matrix, which leads to deterioration studied mixtures. Ozonolysis affects strength parameters polylactide-polyethylene samples as well pho...

The formation of secondary organic aerosol (SOA) from both ozonolysis and hydroxyl radical (OH)-initiated oxidation of α-pinene under conditions of high nitric oxide (NO) concentrations with varying relative humidity (RH) and aerosol acidity was investigated in the University of North Carolina dual outdoor smog chamber facility. SOA formation from ozonolysis of α-pinene was enhanced relative to...

Abstract. Stressed plants and polymer production can emit many unsaturated volatile organic esters (UVOEs). However, secondary aerosol (SOA) formation of UVOEs remains unclear, especially under complex ambient conditions. In this study, we mainly investigated ethyl methacrylate (EM) ozonolysis. Results showed that a substantial increase in H2SO4 particles promoted SOA with increasing SO2. An im...

Many studies have proved that ozone can decompose aflatoxins in peanuts, while polyphenols in peanut skins can also be destroyed due to its strong oxidative capacity. The polyphenols and their oxidative products in the peanut skin extracts at different ozonated times were separated and identified by HPLC-Q-TOF/MS. Based on the accurate molecular weight from mass spectrogram, and consulted the r...

Electrodynamic balance–mass spectrometry allows to study the ozonolysis of linoleic acid under strongly different ozone concentrations and reveals importance autoxidation at low concentrations.
