in this paper effect of sio 2 nanoparticles was investigated on potato starch films. potato starch films were prepared by casting method with addition of nano-silicon dioxide and a mixture of sorbitol/glycerol (weight ratio of 3 to 1) as plasticizers. sio 2 nanoparticles incorporated to the potato starch films at different concentrations 0, 1, 2, 3, and 5% of total solid, and the films were dri...

Using a nationally representative, longitudinal sample of Asian American late adolescents/young adults (ages 18-26), this article investigates the link between peer effects, school climate, on the one hand, and substance use, which includes tobacco, alcohol, and other illicit mood altering substance. The sample (N = 1585) is drawn from the National Longitudinal Study of Adolescent Health (Waves...

throughout the present, caseinate based edible films containing extracts of pomegranate peel were prepared in 3 levels of ×1, ×1.5 and ×2 (mic) and the physicomechanical, thermal, antimicrobial, and barrier properties of the films studied. to assess the microstructure changes resulting from the addition of the antimicrobial extracts, sem images were prepared from the surface and cross-section o...
