MBJ-neutrosophic ideals of BCK/BCI-algebras [PDF]

open access: yesOpen Mathematics, 2019
Abstract The notion of MBJ-neutrosophic ideal is introduced, and its properties are investigated. Conditions for an MBJ-neutrosophic set to be an MBJ-neutrosophic ideal are provided. In a BCK/BCI-algebra, a condition for an MBJ-neutrosophic set to be an MBJ-neutrosophic ideal is given. In a BCK-algebra, a condition for an MBJ-neutrosophic subalgebra to

Half-metallicity and giant magneto-optical Kerr effect in N-doped NaTaO$_3$

open access: yes, 2012
We employ density functional theory using the modified Becke-Johnson (mBJ) approach to investigate the electronic and magneto-optical properties of N-doped NaTaO$_3$.

Fermi Surface of Metallic V$_2$O$_3$ from Angle-Resolved Photoemission: Mid-level Filling of $e_g^{\pi}$ Bands [PDF]

open access: yes, 2016
Using angle resolved photoemission spectroscopy (ARPES) we report the first band dispersions and distinct features of the bulk Fermi surface (FS) in the paramagnetic metallic phase of the prototypical metal-insulator transition material V$_2$O$_3$. Along

Structural Reassignment and Absolute Stereochemistry of Madurastatin C1 (MBJ-0034) and the Related Aziridine Siderophores: Madurastatins A1, B1, and MBJ-0035 [PDF]

open access: yesJournal of Natural Products, 2017
The madurastatins are pentapeptide siderophores originally described as containing an unusual salicylate-capped N-terminal aziridine ring. Isolation of madurastatin C1 (1) (also designated MBJ-0034), from Actinomadura sp. DEM31376 (itself isolated from a deep sea sediment), prompted structural reevaluation of the madurastatin siderophores, in line with

Assessment of the GLLB-SC potential for solid-state properties and attempts for improvement

open access: yes, 2017
Based on the work of Gritsenko et al. (GLLB) [Phys. Rev. A 51, 1944 (1995)], the method of Kuisma et al. [Phys. Rev. B 82, 115106 (2010)] to calculate the band gap in solids was shown to be much more accurate than the common local density approximation ...

Ramsey-type microwave spectroscopy on CO ($a^3\Pi$)

open access: yes, 2014
Using a Ramsey-type setup, the lambda-doublet transition in the $J=1,\, \Omega=1$ level of the $a^3\Pi$ state of CO was measured to be 394 064 870(10) Hz.

Origin of layer number dependent linear and nonlinear optical properties of two-dimensional graphene-like SiC

open access: yes, 2017
We theoretically discuss the physical origin of the dielectric constants [{\epsilon}({\omega})] and second harmonic generation coefficients [\{chi}(2)({\omega})] of the ABA-stacked two-dimensional graphene-like silicon carbide (2D-SiC) with the number of

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

open access: yesAdvanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

Structure and optical properties of high light output halide scintillators

open access: yes, 2010
Structural and optical properties of several high light output halide scintillators and closely related materials are presented based on first principles calculations. The optical properties are based on the Engel-Vosko generalized gradient approximation
