GaN nano- and micro-spheres fabricated selectively on silicon
(Elsevier Science BvAmsterdamHolanda, 2007)
Ultra-fast direct growth of metallic micro- and nano-structures by focused ion beam irradiation
(Nature Publishing Group, 2019-10-01)
An ultra-fast method to directly grow metallic micro- and nano-structures is introduced. It relies on a Focused Ion Beam (FIB) and a condensed layer of suitable precursor material formed on the substrate under cryogenic ...
Ordered Array Electrodes Fabricated by a Mask-Assisted Electron-Beam Method as Platforms for Studying Kinetic and Mass-Transport Phenomena on Electrocatalysts
(Wiley-VCH Verlag, 2018-09)
This work describes a method for fabrication of extensive ordered arrays of microelectrodes with varied geometries, surrounded either by an insulating surface of poly(methyl methacrylate) (PMMA) or by a conductive material ...
Study Experimental and Numerical Simulations of the Micro-hardness Tests in AL-FE alloy in Different Laser Beam ScanningEstudio experimental y simulación numérica de las medidas de microdureza en aleaciones Al-Fe en diferentes velocidades de barridos con rayo láser
(Universidad EAFIT, 2019-11-29)
In the Al–2.0 wt.%Fe alloy the laser surface remelting (LSR) treatment was executed to investigate the treated and untreated layers areas, at different laser beam scanning, among them, 80, 100 and 120 mm/s, to respect, was ...
Silver nanowires in poly(methyl methacrylate) as a conductive nanocomposite for microfabrication
(Institute of Physics Publishing, 2016-09)
Anovel nanocomposite resist is presented based on AgNWs dispersed in poly(methyl methacrylate). It is shown that this nanocomposite resist displays sheet resistances below 10 O sq-1 for concentrations of AgNWs higher than ...
Laser-modified titanium surfaces enhance the osteogenic differentiation of human mesenchymal stem cells
(2017-11-28)
Background: Titanium surfaces have been modified by various approaches with the aim of improving the stimulation of osseointegration. Laser beam (Yb-YAG) treatment is a controllable and flexible approach to modifying ...
Aplicação de diferentes métodos de análise de imagens para pesquisa em Endodontia: tomografia computadorizada de feixe cônico, micro-CT e nano-CT
(Universidade Estadual Paulista (Unesp), 2022-03-21)
Imagens tridimensionais são amplamente utilizadas na endodontia para avaliação de técnicas e materiais endodônticos, além de diagnóstico, planejamento e proservação. O objetivo deste estudo foi avaliar diferentes etapas ...
