Structural, optical and electrical properties of DC sputtered indium saving indium-tin oxide (ITO) thin films
(Elsevier GmbH, 2018)
Amorphous indium tin oxide (ITO) thin films with reduced to 50 mass% indium oxide
content were prepared by direct current (DC) sputtering of ITO target in mixed argonoxygen atmosphere onto glass substrates preheated at ...
Electrical characterization of the Macusanite volcanic glass and influence of nuclear fission tracks on electrical conductivity
(2020-11-01)
Direct current dielectrical measurements were performed on samples of natural volcanic glass Macusanite with and without previous heat treatment at 650 °C for 10 h. Samples were analyzed via Source Measure Unit Keithley ...
The Internet of Brain Things: Theoretical Basis for the Usage of Neuralink Chip
(IEEE, 2023)
If the chip called Neuralink is realized and marketable then a wide spectrum of biomedical opportunities shall be available. One of them is the potential usage of chip as an implanted antenna. In fact, once the chip begins ...
Análise da energia utilizada por bisturi elétrico na ablação de tecido orgânico
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Biomédica, 2014-12-19)
Electrosurgery is a surgical technique that uses an electrosurgical device for cutting, drying (desiccation), and coagulation of organic tissue, thereby reducing the risk of bleeding. Electrosurgical device uses sparking ...
Network reconfiguration and loss allocation in a deregulated environment of distribution systems
(2005-12-14)
Low flexibility and reliability in the operation of radial distribution networks make those systems be constructed with extra equipment as sectionalising switches in order to reconfigure the network, so the operation quality ...
