Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A
Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.

Journal of Applied Polymer Science, EarlyView.Treatment of polypropylene fabric in oxygen plasma was used to impart the fabric surface with more hydrophilic surface properties. Changes in bulk properties were minimal as the modification mainly affected the fabric surface. Bulk fabric properties water retention, moisture content and wicking were monitored over a period of 33 days.
