The flesh of fresh apricots when cut and exposed to the air rapidly develops a brown color due to enzymic oxidation. This phenomenon is of great importance in the freezing and freezing storage of fresh apricots and in the preparation of apricots for canning and drying. In commercial freezing the oxidizing enzymes of this fruit are controlled by treatment with dilute SO2 solution or by covering ...

The electrochemistry in liquid SO2 of RuII and OsII dendritic polynuclear complexes (two hexanuclear species, having as the core a bis-chelating ligand, and one decanuclear species, built around a metal core) has been performed together with that of several of their lower-nuclearity analogues (five dinuclear and one trinuclear species), which can be considered as components of the larger dendri...

The main aim of the present work is to study the accumulation of acetaldehyde and Strecker aldehydes (isobutyraldehyde, 2-methylbutanal, isovaleraldehyde, methional, phenylacetaldehyde) during the oxidation of red wines, and to relate the patterns of accumulation to the wine chemical composition. For that, eight different wines, extensively chemically characterized, were subjected at 25°C to th...

The oxidation behavior of fully dense Ti2SC was studied thermogravimetrically in air in the 500–800°C temperature range. The oxidation product was a single-layer of rutile in all cases. At 800°C, the oxide layer was not protective and the oxidation kinetics were rapid. At 600 and 700°C, and up to ~50 h, the kinetics were parabolic before they became linear. It was only at 500°C that the weight ...

We investigated the photosensitizing properties of secondary organic aerosol (SOA) formed during hydroxyl radical (OH) initiated oxidation naphthalene. This SOA was injected into an flow tube and exposed to UV radiation gaseous volatile compounds or sulfur dioxide (SO2). The particles were observed grow in size by photosensitized uptake d-limonene β-pinene. In presence SO2, a production (0.2–0....

Abstract. Sulfur dioxide (SO2) is a major atmospheric pollutant and precursor of sulfate aerosols, which influences air quality, cloud microphysics, climate. Therefore, better understanding the conversion SO2 to essential simulate predict sulfur compounds more accurately. This study evaluates effects in-cloud aqueous-phase chemistry on oxidation in Community Earth System Model version 2 (CESM2)...

Sulfur dioxide (SO2), a major air pollutant in developing countries, is highly toxic to plants. To achieve better air quality and landscape, planting appropriate grass species in severe SO2 polluted areas is very critical. Cynodon dactylon, a widely used warm season turfgrass species, has good SO2-tolerant ability. In this study, we selected 9 out of 38 C. dactylon accessions from Southwest Chi...
