Synthesis of a silver nanoparticle ink for fabrication of reference electrodes
Autor: Ana Elisa Ferreira Oliveira, Arnaldo César Pereira, Mayra Asevedo Campos de Resende, Lucas Franco Ferreira
Publikováno v: Talanta Open, Vol 5, Iss , Pp 100085- (2022)
The silver nanoparticle (AgNP) ink synthesized was simple, well-dispersed, did not need sintering, had excellent conductivity and can be used as a conductive ink in several areas, particularly in the fabrication of reference electrodes. The AgNP ink

Development of highly stable conductive multiwalled carbon nanotube ink using covalent and non-covalent functionalization for electrochemical sensors
Autor: Ana Elisa Ferreira Oliveira, Arnaldo César Pereira, Lucas Franco Ferreira
Publikováno v: Journal of Electrochemical Science and Engineering, Vol 11, Iss 3 (2021)
The purpose of this work was the fabrication of a conductive carbon nanotube (CNT) ink. The proposed CNT ink remained remarkably stable over several months. The method includes combining the covalent and non-covalent functionalization, resulting in i

De Tolstói a Toy Story: um caso de texto multimodal e seus estratos digitais
Autor: Ana Elisa Ferreira Ribeiro
Publikováno v: Texto Digital, Vol 17, Iss 1 (2021)
Neste artigo, partimos da relação existente, mas não dependente, entre multiletramentos e estudos de multimodalidade para, então, abordar um texto de produção e distribuição digitais, empregando parcialmente uma metalinguagem proposta por Kre

What is and what is not a book: its materiality and editorial processes
Autor: Ana Elisa Ferreira Ribeiro
Publikováno v: Fórum Linguístico, Vol 9, Iss 4, Pp 333-341 (2013)
In this paper, we propose a discussion on e-books as a marked product, not just as a discursive framework or because its format, but also by an editorial process at least partially distinct from the printed book. Moreover, the concepts of material fo

Validação de métodos cromatográficos por clae para análise das vitaminas B1, B2, B6 e niacina naturalmente presentes em farinha de cereais Validation of hplc methods for analysis of vitamins B1, B2, B6 and niacin naturally present in cereal flours
Autor: Ana Elisa Ferreira Presoto, Ligia Bicudo de Almeida-Muradian
Publikováno v: Química Nova, Vol 31, Iss 3, Pp 498-502 (2008)
Complex B vitamins are present in some cereal foods and the ingestion of enriched products contributes to the recommended dietary intake of these micronutrients. To adapt the label of some products, it is necessary to develop and validate the analyti

Fully handwritten electrodes on paper substrate using rollerball pen with silver nanoparticle ink, marker pen with carbon nanotube ink and graphite pencil
Autor: Ana Elisa Ferreira de Oliveira, Arnaldo César Pereira, Lucas Franco Ferreira
Publikováno v: Analytical Methods. 14:1880-1888
Herein, a so-called carbon nanotube (CNT) electrode was printed in on a paper substrate using the handwriting technique and carbon nanotube ink in a marker pen to print the working electrode, graphite pencil to print the counter electrode and graphit

Experimental vs. simulation analysis of LoRa for vehicular communications
Autor: Thales T. Almeida, Ana Elisa Ferreira, Fernando Molano Ortiz, Luís Henrique M. K. Costa
Publikováno v: Computer Communications. 160:299-310
LoRa, a Low Power Wide Area Network (LPWAN) technology, demands reduced network infrastructure to cover a large area, with low power consumption. In the context of vehicular communications, LoRa has the potential to support monitoring and cooperative

β-Cyclodextrin electropolymerization: mechanism, electrochemical behavior, and optimization
Autor: Ana Elisa Ferreira Oliveira, Guilherme Braga Bettio, Arnaldo César Pereira
Publikováno v: Chemical Papers. 73:1795-1804
The main purpose of this manuscript was to study the electropolymerization using cyclodextrin as a monomer for application as electrochemical sensors. This process was first studied by Morales et al. and will be discussed in this work using a systema
