(Universidade Estadual Paulista (Unesp), 2015-09-21)
This project is a website with interactive pages whose purpose is to explain in a contextualized way and in an accessible language to the consumer the chemical components that are part of the formulation of various products. ...
Numerical Solution for Reversible Chemical Reaction Models with Interactive Fuzzy Initial Conditions
(Springer, 2022-01-01)
This manuscript studies the reversible chemical reactions described by a system of fuzzy differential equations, with initial conditions given by interactive fuzzy numbers. The fuzzy solution is given by the Euler method ...
Stacking faults in SiCf/SiC composite obtained by chemical vapor reaction process
(2008-12-01)
SiC fiber-reinforced SiC matrix composite (SiCf/SiC) is one of the leading candidates in ceramic materials for engineering applications due to its unique combination of properties such as high thermal conductivity, high ...
A quantum chemical study on the formation of phosphorus mononitride
(Elsevier B.V., 2009-09-18)
The chemical mechanism of the (1)PN formation was successfully studied by using the CCSD(T)/6-311++G(3df,3pd) level of theory. The (1)NH(3) + (3)PH and (4)P + NH(3) reaction paths are not energetically favorable to form ...
Physical characterization of K-doped 0.9PMN-0.1PT synthesized by an association of the columbite route and the polymeric precursor method
(2005-12-01)
The solid solution 0.9PbMg 1/3Nb 2/3O 3-0.1PbTiO 3 is one of the most widely investigated relaxor ceramic, because of its high dielectric constant and low sintering temperatures. PMN-PT powders containing single perovskite ...
Chemical properties of different peats depending on origin and analytical method
(2009-10-23)
The chemical properties of 12 different peats have been analyzed by methods from VDLUFA (German Association of Agricultural Analysis and Research Institutes) and EN (European Committee for Standardization, Technical Committee ...
Chemical properties and decay resistance of eucalyptus grandis wood from steamed logs
(2012-12-01)
The objective of this study was evaluate the effect of the log steaming on the chemical properties and decay resistance of Eucalyptus grandis wood. Logs with diameter between 20 and 22 cm were studied. Half of logs were ...
Influence of storage on chemical properties of different peats
(2009-10-23)
The change of chemical properties during storage of 12 fertilized bagged peats of different origins at high temperature was investigated. The average values for N, soluble salts and EC decreased significantly, whereas the ...
Variables Involved in the Planting of Rice in the Rice Husk
(Trans Tech Publications Ltd, 2012-01-01)
Rice production in Brazil in 2010 was approximately 12,2 million tons, and to reach that amount several planting techniques were used with different strains of rice in different rice-growing areas. Since Rice Husk Ash (RHA) ...
