13. Polyamide 11 porous films by NIPS: the influence of miscibility and polymer crystalline formation in pores structure and morphology
This study described the morphology, crystallinity, thermal and mechanical characterization of Polyamide 11 (PA11) porous film prepared by non-solvent induced phase separation (NIPS) method using formic acid (FA) as solvent. In addition, the miscibility of PA11/FA/H2O system was performed to generate a ternary phase diagram. The porous films morphology was i

16. Reduced Graphene Oxide/Ruthenium Oxide Hexacyanoferrate Nanocomposite for Electrochemical Determination of Ethanol in Commercial Samples
Reduced graphene oxide/ruthenium oxide hexacyanoferrate (rGO/RuOHCF) modified electrode showed synergic activity between the materials attested by the increase of electrochemical current and stability. The preparation of the nanocomposite was made by a simple two-step electrochemical approach. The material structure was characterized by spectroscopic techniq

19. Trypanocidal Activity and Increased Solubility of Benznidazole Incorporated in PEG 4000 and Its Derivatives
Selecting a polymer depends on its characteristics, the properties of the drug and of the remaining ingredients in the formulation. The drug, when incorporated into a polymeric matrix, can show several advantages when compared with its conventional form. In this context, this work describes the preparation and characterization of polyethylene glycol (PEG 400

20. Incorporation of Fluorescent Dyes in Electrospun Chitosan/Poly(ethylene oxide)
Polymeric films have been increasingly investigated due to the ease of miniaturization and integration in several sensor devices. Films obtained from the electrospinning technique have a controlled diameter and homogeneity, and substances can be incorporated into the polymeric network. Electrospinning fiber of chitosan (Ch) and poly(ethylene oxide) (PEO) was

21. FETISHIZED READING AND WRITING IN THE ENGLISH PATIENT AND ATONEMENT FILM ADAPTATIONS
Abstract Reading and writing-related objects, whether in the form of books, letters, or typewriters, are central elements in the films The English Patient, by Anthony Minghella (1996), and Atonement, by Joe Wright (2007), both adapted from novels. By drawing similarities between these two adaptations (Hutcheon 2013; Elleström 2017), the present text illustr

22. SIN NOMBRE, BABEL, AND THE CONFLICTS IN CONTACT ZONES
Abstract Contact zones can be understood as spaces where cultures meet and establish relations of power based on historical processes of domination and inequality. In such spaces and under such circumstances, power dynamics are sometimes resulted from the act of geographic dislocation, executed either by the individual from a central culture who is seen as t

23. Green biosynthesized Satureja rechingeri Jamzad-Ag/poly vinyl alcohol film: quality improvement of Oncorhynchus mykiss fillet during refrigerated storage
Abstract The nanosilver food packaging films were developed by polyvinyl alcohol activated with Satureja rechingeri extract (S-AgNPs/PVA) using the solvent casting to evaluate the freshness of Oncorhynchus mykiss fillets during 14 days at the refrigerated temperature. The 160 pieces of fish were enfolded in 4 types of films as main group-series. The main com
