Poly(vinyl chloride) Films Incorporated with Antioxidant ZnO-Flavonoid Nanoparticles: A Strategy for Food Preservation

Autor: Lilian R. Braga, Maria Graciele Oliveira, Leonardo M. Pérez, Ellen T. Rangel, Fabricio Machado

Publikováno v: Foods, Vol 13, Iss 17, p 2745 (2024)

Antioxidant films were prepared using poly(vinyl chloride) (PVC) incorporated with 0.5% or 1.0% zinc oxide (ZnO)-flavonoid (quercetin or morin) nanoparticles (NPZnO-Q% or NPZnO-M%) via the casting method. NP incorporation within the polymer matrix in

Simple synthesis of active films based on PVC incorporated with silver nanoparticles: Evaluation of the thermal, structural and antimicrobial properties

Autor: Lilian R. Braga, Paulo A. Z. Suarez, Ellen Tanus Rangel, Fabricio Machado

Publikováno v: Food Packaging and Shelf Life. 15:122-129

In this work, active antimicrobial films were synthetized with 1.0% to 8.0% silver ions incorporated into polyvinyl chloride (PVC), utilizing a simple solvent casting method was accomplished in a single step. The incorporation of silver in the PVC af

Vitamin A and vitamin E interaction behavior on chitosan microspheres

Autor: Thiago O. Carvalho, Sheila M. Evangelista, Alexandre G.S. Prado, André L. F. Santos, Carolina P. Pedroso, Lilian R. Braga

Publikováno v: Journal of Thermal Analysis and Calorimetry. 106:415-420

Chitosan is a biodegradable natural polymer with great potential for pharmaceutical applications due to its biocompatibility, high charge density, and non-toxicity. In this study, chitosan microspheres were successfully prepared by an adapted method

Calorimetric studies of removal of nonsteroidal anti-inflammatory drugs diclofenac and dipyrone from water

Autor: Alexandre G.S. Prado, Sheila M. Evangelista, Thiago O. Carvalho, Lilian R. Braga, Ana E. B. Matias

Publikováno v: Journal of Thermal Analysis and Calorimetry. 106:475-481

Chitosan microspheres were applied to remove the pollutants diclofenac and dipyrone from water. Adsorption studies were adjusted to Langmuir equation. The maximum number of adsorbed moles gave 5.25 × 10−4 and 4.83 × 10−4 mol of diclofenac and d
