Self-assembled vortex crystals induced by inhomogeneous magnetic textures
(2019-01-01)
We investigate the self-assembly of vortices in a type-II superconducting disk subjected to highly nonuniform confining potentials produced by inhomogeneous magnetic textures. Using a series of numerical experiments performed ...
Emergent Geometry of Inhomogeneous Planar Crystals
(American Physical Society, 2018-03)
Uniform triangular crystals are the ground state for particles that interact isotropically in two dimensions. However, when immersed in an external potential, for example, one arising from an electric field, a flow field, ...
Dispersed lipid liquid crystalline phases stabilized by a hydrophobically modified cellulose
(2007-02-27)
Aqueous dispersions of monoolein (MO) with a commercial hydrophobically modified ethyl hydroxyethyl cellulose ether (HMEHEC) have been investigated with respect to the morphologies of the liquid crystalline nanoparticles. ...

Engenharia de cristais: estudo conformacional, topológico e energético de t-butilpirazóis e bis-t-butilpirazóis
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2019-02-22)
This work presents a proposed crystallization mechanism and conformational study of regioisomers of 5(3)-aryl-3(5)-carboxyethyl-1-(1,1-dimethylethyl)-1H-pyrazole (aryl, 4-X-C6H4, where X = H, F, Cl and Br) and a series of ...
Interplay between conformation and crystal packing in aryl propargyl ethers: Structural and spectroscopic properties of 2-(prop-2-yn-1-yloxy)acene derivatives
(Wiley Blackwell Publishing, Inc, 2019-09-13)
The 2-(prop-2-yn-1-yloxy)naphthalene (compound I) and 1-nitro-2-(prop-2-yn-1-yloxy)benzene (compound II) were prepared in excellent yields by the reaction of propargyl bromide with 2-naphthol and 2-nitrophenol, respectively. ...
Comparison of conformations of diesters of stabilized phosphonium ylides in solution and in the crystal
(2009)
Computed bond lengths and angles of methyl ethyl and dimethyl triphenyl phosphonium ylidic diesters, 1b, c, respectively, are similar to those in the crystal, as for the diethyl ester, 1a, where both acyl oxygens are anti ...
