DSC study of selected antioxidants and their binary
DSC study of selected antioxidants and their binary mixtures in styrene–butadiene rubber. In the case of mixtures the best stabilizing properties can be assigned to the mixture of 6PPD with 4-phenylamino phenol. The cooperation between antioxidants in the binary mixtures was characterized by the values of S-factor. The results indicate that only the mixture of 6PPD with 4-phenylamino phenol exhibits a synergistic effect at 130 °C.

IJERPH | Free Full-Text | An Increased Risk of Stunting
We conducted an observational study of 194 pregnant women from two different study sites in rural Cambodia. Socioeconomic and anthropometric data was obtained from the women and their newborns. In addition, we collected blood and urine samples from the women for further analyses in planned papers. There were significant differences between the two study groups for clinical outcomes.

Compatibility study of rosmarinic acid with excipients
In this regard, the aim of the present study was to evaluate, for the first time, the compatibility of RA with excipients commonly used in solid dosage forms at a 1:1 (RA:excipient) ratio using differential scanning calorimetry (DSC), thermogravimetry (TG), Fourier-transform infrared (FTIR), solid-state nuclear magnetic resonance (ssNMR), and ...

The synthesis of novel Schiff base antioxidants to promote
There is of great interest in promotion of anti-thermal aging properties of natural rubber (NR) to improve the applicability. In this study, two novel Schiff base antioxidants (SBAOs) for NR were synthesized utilizing 4-aminodiphenylamine with 3,5-Di-tert-butyl-2-hydroxybenzaldehyde or cinnamic aldehyde in an ethanol medium.

Antioxidant activity of p-phenylenediamines studied by DSC
Thermogravimetry (TGA) and differential scanning calorimetry (DSC) were used to study the oxidation of ethylene/propylene rubber stabilized with several antioxidants, among them IPPD, where the onset temperature of the oxidation peak was considered as a measure of the antioxidant activity , .
