The Role Of Glu/Gly/Zif-8 Edible Film In Improving The Superior Rheological And Water Vapor Barrier Properties And Antibacterial Activity For Active Food Packaging, Nancy Siti Djenar, Kardian Rinaldi, Dina Nur Rahma, Dina Kustiana

Chimica et Natura Acta

The low barrier to water vapor and gas is a critical limitation of glycerol-plasticized gluten-based edible films (GBEF) for food packaging applications. In this study, gluten (Glu) and glycerol (Gly) were cross-linked with 0.25–1.00% (w/v) zeolitic imidazolate framework-8 (ZIF-8) to improve interfacial compatibility and enhance the structural integrity of the film matrix. The formation of hydrogen bonds and electrostatic interactions between ZIF-8 and the Glu/Gly matrix strengthened the chemical network, resulting in increased tensile strength (TS). The water vapor transmission rate (WVTR) of Glu/Gly/ZIF-8 edible films (Glu/Gly/ZIF-8 EF) ranged from 1.085 to 1.453 g/m²/24 h, indicating significantly improved barrier properties. …

A New Testament Theology Of Evangelistic Prayer, Preston Gagnon

Doctoral Dissertations and Projects

Evangelistic prayer is widely assumed to be appropriate, but the biblical basis for the practice has been insufficiently argued. Some evangelistic resources assume evangelistic prayer is necessary. Others overlook the practice, and many discuss evangelistic prayer by making minimal arguments for the practice. Due to the lack of comprehensive arguments for evangelistic prayer, some authors have been able to claim that prayers for the lost are unbiblical. This dissertation enters the conversation by arguing that the New Testament presents evangelistic prayer as a biblically mandated, exemplified, and theologically supported practice. This argument is made by expositing twelve key New Testament …
