Crystalline structures and preferential surfaces developed in the Al-Ni-O System
(Elsevier, 2019-08)
This work describes the synthesis of an Al2O3-Ni-Al2NiO4-NiO composite. The composite is obtained in two-steps. At the first step, powders of Al, Ni and C are mechanically mixed and compressed as pellets. At the second ...
Chemical Etching and TEM Crystalline Quality Assessment of Single Crystalline ZnSe Ingots Grown by I2 Vapor Phase Transport
(Cosmos Scholars Publishing House, 2015-12)
Crystalline defects were studied in single crystalline ZnSe grown by chemical transport using I2 as gaseous carrier. Transmission electronic microscopy determined an excellent structural order in the micrometric and ...
Physico-chemical and structural properties of crystalline inulin explain the stability of Lactobacillus plantarum during spray-drying and storage
(Elsevier Science, 2018-11)
The stabilizing capacity of crystalline inulin during spray-drying and storage of Lactobacillus plantarum CIDCA 83114 was assessed. In a first step, the physical properties of the matrices were investigated, using amorphous ...
Unveiling a crystalline topological insulator in a Weyl semimetal with time-reversal symmetry
(American Physical Society, 2014-09)
We consider a natural generalization of the lattice model for a periodic array of two layers, A and B , of spinless electrons proposed by Fu [Phys. Rev. Lett. 106, 106802 (2011)] as a prototype for a crystalline insulator. ...
Modified Genetic Algorithm to Model Crystal Structures: III. Determination of Crystal Structures Allowing Simultaneous Molecular Geometry Relaxation
(John Wiley & Sons Inc, 2004-12)
The modified genetic algorithm (MGAC) has been extended to allow simultaneous relaxation of molecular geometry during optimization of the crystalline structure. The method was applied to L-alanine and DL-alanine for two ...
Crystalline electrical field effects on powdered RE Cu4Al8 (RE = Tb, Dy, Ho and Er) intermetallic compounds
(Elsevier, 2021-03)
In this work, structural and magnetic properties RE Cu4Al8 (RE = Tb, Dy, Ho and Er) family of compounds are reported. Measurements of X-ray diffraction, tem- perature (T) and magnetic eld (H) dependencies of magnetization ...

Characterization of nanocellulose obtained from Cereus Forbesii (a South American cactus)
(Universidade Federal de São Carlos, 2019-11)
Crystalline cellulose nanofibers are obtained from the bark of Cereus Forbesii, a cactus native to the arid areas of South America. The obtaining of cellulose nanofibers was carried out in several steps: pretreatment of ...
