Characterization of self-cleaning properties on superhydrophobic aluminum surfaces fabricated by direct laser writing and direct laser interference patterning
(Elsevier B.V., 2020-09)
Self-cleaning ability on technical surfaces can increase the added value of a product. A common path to achieve this property is making the surface superhydrophobic so that water droplets can roll down, picking up dirt ...
Platinum nanoparticles produced by EG/PVP method: The effect of cleaning on the electrooxidation of glycerol
(Elsevier, 2013-05)
Carbon supported Pt nanoparticles (NPs) have been prepared through polyols method using PVP. As observed with a large number of surfactants employed in NPs synthesis, it is very difficult to attain an efficient NPs cleaning, ...
An analytical method for selecting the optimal nozzle external geometry for fluid dynamic gauging
(Elsevier, 2011-08)
Fluid dynamic gauging (FDG) was developed to measure, in situ and in real time, the thickness of a soft deposit layer immersed in a liquid without contacting the surface of the layer. An analysis based on the lubrication ...
Effect of different rotary instrumentation techniques and thermoplastic filling on apical sealing
(Faculdade De Odontologia De Bauru - USP, 2004-03)
The aim of this study was to evaluate apical sealing after root canal treatment using two different rotary instrumentation techniques and two thermoplastic root canal filling techniques. The study was performed in 115 human ...
Influence of Hero Apical instruments on cleaning ovoid-shaped root canals
(Sociedade Brasileira de Pesquisa Odontológica, 2011)
The cleaning capacity of Hero 642 nickel-titanium files, complemented by the Hero Apical instruments in flattened roots, was determined by histological analysis, considering the area of action of the instruments on the ...
Estudo da influência do formato das partículas na operação de filtração de gases
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2009-09-01)
Particle morphology is a parameter which deserves great attention in industrial processes. This parameter affect some processes and products like medicines production and cosmetics which are developed by the compaction ...
Method for determination of root curvature radius using cone-beam computed tomography images
(Fundação Odontológica de Ribeirão Preto, 2008)
This article describes and discusses a method to determine root curvature radius by using cone-beam computed tomography (CBCT). The severity of root canal curvature is essential to select instrument and instrumentation ...
Behavior of hardened steel grinding using MQL under cold air and MQL CBN wheel cleaning
(Springer, 2019-12-01)
Nowadays, environmental concern and the search for environmentally friendly techniques have contributed to industrial development towards sustainability. Production without social and environmental impact is one of the ...
Shaping ability of rotary or reciprocating systems for oval root canal preparation: a micro-computed tomography study
(2018-03-10)
Objectives: To evaluate the shaping ability and cleaning after oval root canal preparation using one or more instruments in reciprocating or rotary motion. Materials and methods: Oval-shaped mandibular incisors were selected, ...
