Antioxidant activity and lipid peroxidation of selected wheat cultivars under salt stress Dr. Syed Rizwan Abbas Academia.edu. The antioxidant activity, total phenolic content (TPC) and lipid peroxidation was measured among 15 cultivars of wheat which are commonly used in Pakistan and the effect of salt stress was also evaluated.

Synthesis and aging properties of reactive antioxidant
The rubber antioxidant N‐(4‐anilinophenyl) methacrylamide (NAPM) was synthesized by a two‐step reaction using thionyl chloride (SOCl 2) with methacrylic acid (MAA) and consequently 4‐aminodiphenylamine (ADPA) as precursors.NAPM was characterized by IR, 1 H NMR and elemental analysis. Thermal stability, aging property of NAPM and mechanical properties of

- Does 4010na/cb/Nr composite increase thermo-oxidative aging resistance?
- The results shall indicate that, in comparison with 4010NA/CB/NR composite, there existed synergistic effect of antioxidant 4010NA and silica in 4010NA/SiO2 /NR composite on greatly enhancing thermo-oxidative aging resistance of NR material.
- Does antioxidant 4010na increase k value in Nr/CB/Nr composite?
- Moreover, upon adding antioxidant 4010NA into NR or CB/NR composite, the K values for 4010NA/NR or 4010NA/CB/NR composite did not exhibit a significant improvement. In contrast, it is noticeable that the addition of 4010NA caused a significant increase in K value for 4010NA/SiO 2 /NR composites in comparison with SiO 2 /NR composite.
- Does antioxidant 4010na reduce FFV and FCV of NR?
- (1) By means of QM simulation, the protective mechanism of antioxidant 4010NA for NR was elucidated quantitatively from the point of free energy of dissociation and energy barrier of reaction. (2) The addition of silica was capable of reducing FFV and FCV of NR, thereby improving O 2 barrier ability of NR.
- Does Nr composite have a Good thermo-oxidative stability?
- Consequently, the filled NR composite was of a better thermo-oxidative stability than the unfilled NR system. (3) Due to vulcanization accelerate effect of 4010NA, 4010NA/SiO 2 /NR composite had an appropriate high cross-linking density during the course of thermo-oxidative aging.
- Does antioxidant 4010na and silica enhance thermo-oxidative aging assistance?
- In this work, the synergistic effects of antioxidant 4010NA and silica on enhancing thermo-oxidative aging assistance for NR were investigated by experiments and molecular simulations, and the mainly conclusions were generalized as follows:
- Which raw materials are used to prepare Nr & 4010na blends?
- To avoid the disturbance of other additives, we only used raw materials NR, filler (CB or SiO 2 ), and antioxidant 4010NA to prepare NR, 4010NA/NR, CB/NR, 4010NA/CB/NR, SiO 2 /NR, and 4010NA/SiO 2 /NR blends. The weight loss of these blends were measured by TGA at 150 °C under nitrogen atmosphere.
