Experimental and numerical study of heat transfer in hot machined workpiece using infrared radiation
(2014)
One of the greatest problems found in machining is related to the cutting tool wear. A way for increasing the tool life points out to the development of materials more resistant to wear, such as PCBN inserts. However, the ...
Simultaneous preconcentration of copper, zinc, cadmium, and nickel in water samples by cloud point extraction using 4-(2-pyridylazo)-resorcinol and their determination by inductively coupled plasma optic emission spectrometry
(ELSEVIER SCIENCE BV, 2009)
A procedure for simultaneous separation/preconcentration of copper. zinc, cadmium, and nickel in water samples, based on cloud point extraction (CPE) as a prior step to their determination by inductively coupled plasma ...
Métodos de controle de deformações para análise não-linear de estruturas
(Universidade Federal de Minas GeraisUFMG, 2004-03-31)
This work discusses the determination of the equilibrium paths in the nonlinear finite element structural analysis. A detailed study about the incremental-iterative procedures, that use load and displacement combinations ...
Methods for Lithium Ion NASICON Preparation: From Solid-State Synthesis to Highly Conductive Glass-Ceramics
(2020-12-10)
Lithium ion-containing Na+ Super Ionic Conductor (NASICON) electrolytes are important materials for new energy-storage technologies. The NASICON abbreviation represents several compounds with similar structures applied as ...
Effect of calcium on the structural properties of Ba(1-x)Ca (x) TiO3 particles synthesized by complex polymerization method
(Springer, 2014-04-01)
Ferroelectric materials, such as barium titanate (BaTiO3), have been extensively studied for application in electronic and optical devices. The substitution of Ba by Ca is an effective method to improve the piezoelectricity ...
Insights of adsorption isotherms with different gases at 77 K and their use to assess the BET area of nanoporous silica materials
(Springer, 2021-09)
There is a well-known relationship between porous materials performance in a given process and their textural properties. These properties include specific surface area, among others, where the most widely used experimental ...
Ni/C nanostructures: Impregnating-method preparation, textural and structural features, and catalytic property for the hydrogen production
(Cambridge University Press, 2022)
Desenvolvimento de método para a análise quantitativa da rugosidade de substratos cerâmicos argilosos
(Universidade do Vale do Rio dos Sinos, 2021-08-26)
The diversification of materials used as substrates in Civil Construction hinders the standardization of building systems, increasing the probability of pathological manifestations. An example of this is the detachment of ...
