Revisiting (anti)aromaticity and chemical bond in planar BXNX clusters (x = 2-11)

Relativistic effects on the ring current strengths of the substituted borazine: B3N3H6 ( X=H, F, Cl, Br, I, At)
(2019)
In this study, we report about the relativistic effects on the aromaticity of borazine, B3N3H6, and their halogenated derivatives (B3N3F6, B3N3Cl6, B3N3Br6, B3N3I6, and B3N3At6), via the magnetically-induced current density ...
Reversing the persistent current of particles in a driven optical ring lattice
(2015)
We study the dynamics of persistent bosonic currents in closed-loop atom circuits in the form of ring lattices and under the action of time periodic driving. The closed-loop atom circuits are described by a Bose-Hubbard ...
Aromaticity of [M-3(mu-X)(3)X-6](0/2-) (M = Re and Tc, X = Cl, Br, I) Clusters Confirmed by Ring Current Analysis and Induced Magnetic Field
(2018)
We present new evidence that supports the aromatic character of the clusters of formula: [M-3(mu-X)3X6](0/2-) (M = Re and Tc, X = Cl, Br, I). Our computations clearly show that these clusters present a special response to ...
Canonical orbital contributions to the magnetic fields induced by global and local diatropic and paratropic ring currents
(John Wiley and Sons Inc., 2017)
Propriedades mecânicas de peças com dimensões estruturais de Pinus spp: correlação entre resistência à tração e classificação visual
(Sociedade de Investigações Florestais, 2009)
A redução da disponibilidade de espécies de madeiras nativas e seus efeitos na economia, associada ao fortalecimento dos conceitos de preservação ambiental, criou a necessidade de desenvolvimento de alternativas viáveis ...
Retention force and wear characteristics of three attachment systems after dislodging cycles
(2018-11-01)
Several attachment systems for mandibular implant-supported overdentures are currently available and studies are required to understand their mechanical properties. The objective of this study was to evaluate the retention ...
