Lithium dual uptake anode materials: crystalline Fe3O4 nanoparticles supported over graphite for lithium-ion batteries
(Pergamon-Elsevier Science Ltd, 2017-12)
Graphite, the usual anode material for current technology of lithium ion batteries (LIB), has great advantages and its processing is widely known and industrially feasible. For improving the anode's capacity, recent research ...
Aspects of the anodic behaviour of duplex stainless steels aged for long periods at low temperatures
(2003)
Duplex stainless steel samples were aged at low temperatures (300 and 400 °C) for 1000 and 2000 h. Their anodic behaviour was studied in a 0.1 N concentration of sulphuric acid, which revealed that the polarisation curves ...
Electro-catalytic performance of 60%NiO/Ce0.9Zr0.1O2 cermets as anodes of intermediate temperature solid oxide fuel cells
(Elsevier, 2013-03-26)
This paper analyses the electrocatalytic performance of a 60%NiO/Ce0.9Zr0.1O2 anode under reducing atmospheres, using a symmetric cell configuration, [anode/electrolyte/anode], with Samaria doped Ceria (SDC) as electrolyte. ...
Dual-surface modification of titanium alloy with anodizing treatment and bioceramic particles for enhancing prosthetic devices
(Springer, 2017-04)
In this work, two strategies of surface modification of metallic biomedical implants are presented. An anodizing treatment onto titanium surface to enhance a barrier effect for minimizing corrosion and a bioactivation of ...
Bi-Anodal Transcranial Direct Current Stimulation Combined With Treadmill Walking Decreases Motor Cortical Activity in Young and Older Adults
(2021-12-03)
Background: Walking in the “real world” involves motor and cognitive processes. In relation to this, declines in both motor function and cognition contribute to age-related gait dysfunction. Transcranial direct current ...
Producción de bioelectricidad utilizando nanofibras duales de TiO2/carbón como electrodo de una celda de combustible microbiana

Determination of electrochemical parameters and corrosion rate for carbon steel in un-buffered sodium chloride solutions using a superposition model
(2007)
Corrosion of carbon steel in un-buffered NaCl solutions was studied applying linear potential sweep technique to a rotating disk electrode. Current-potential curves were obtained from linear potential sweep at a rate of 1 ...
Use of Cyclic Voltammetry to Describe the Electrochemical Behavior of a Dual-Chamber Microbial Fuel Cell
(MDPI, 2019-09-14)
Cyclic voltammetry (CV) was used in this work to describe the electrochemical behavior of a dual-chamber microbial fuel cell (MFC). The system performance was evaluated under vacuum and non-pressurized conditions, different ...
Sistema bioeletroquímico para remoção de corante tetra-azo em solução aquosa usando eletrodos de grafite
(Universidade Federal de PernambucoUFPEBrasilPrograma de Pos Graduacao em Engenharia Civil, 2019)
Estimulação transcraniana por corrente contínua durante o exercício aeróbio na doença de Parkinson: efeitos agudos na atividade cortical, cognição e andar
(Universidade Estadual Paulista (Unesp), 2019-08-07)
Dentre os comprometimentos motores associados à doença de Parkinson (DP), os distúrbios do andar são os mais incapacitantes aos pacientes. Disfunções cognitivas e do córtex cerebral, presentes na DP, influenciam nos ...
