The Structural Design of a Complete Band Gap using Non-Uniform Photonic Crystals with Low Index Material

open access: yesMajlesi Journal of Electrical Engineering, 2023
This study presents a photonic bandgap formation in a non-uniform 2D photonic crystal structure with low index rods relative to the air background. In order to find an absolute photonic band gap formation, photonic lattices of two non-uniform square and ...

The AdS 3 × S 1 chiral ring

open access: yesJournal of High Energy Physics, 2021
We study AdS 3 × S 1 × Y supersymmetric string theory backgrounds with Neveu-Schwarz-Neveu-Schwarz flux that are dual to N $$ \mathcal{N} $$ = 2 superconformal theories on the boundary. We classify all worldsheet vertex operators that correspond to space-

Investigating the impact of chemical structures on the photocatalytic degradation rates over ZnO nanorods: An oxidative pathways perspective

open access: yesCatalysis Communications, 2023
Zinc oxide (ZnO) nanorods were coated on glass substrates and used as photocatalysts to evaluate the kinetic behavior of three different aromatic structures: i) single aromatic ring (phenol), ii) poly-aromatic ring (methylene blue), and iii) complex ...

Remarks on rings of constants of derivations [PDF]

open access: yesProceedings of the American Mathematical Society, 1989
Let k k be a field of characteristic p > 0 p > 0 and D ≠ 0 D \ne 0 a family of k k -derivations of k [ x , y ] k[x,y] . We prove that k [

l-doublet splittings in Δ vibrational state of 15N14N16O isotopomer

open access: yesChemical Physics Impact, 2021
We report the direct experimental evidences of l-doublet fine splittings between the parity doublet e and f sub-states of β-site isotopomer of nitrous oxide (15N14N16O) in the (1220)←(0220) ro-vibrational transition for l = 2 (i.e.

Determination of Acid Dissociation Constants (pKa) of Bicyclic Thiohydantoin-Pyrrolidine Compounds in 20% Ethanol-Water Hydroorganic Solvent

open access: yesInternational Journal of Analytical Chemistry, 2014
The acid dissociation constants of potential bioactive fused ring thiohydantoin-pyrrolidine compounds were determined by potentiometric titration in 20% (v/v) ethanol-water mixed at 25±0.1°C, at an ionic background of 0.1 mol/L of NaCl using the ...

Gauge invariants, correlators and holography in bosonic and fermionic tensor models

open access: yesJournal of High Energy Physics, 2017
Motivated by the close connection of tensor models to the SYK model, we use representation theory to construct the complete set of gauge invariant observables for bosonic and fermionic tensor models. Correlation functions of the gauge invariant operators

Constants are Definable in Rings of Analytic Functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1994
The analytic functions defined in a fixed domain form a ring with pointwise addition and multiplication. We describe a way to define constants in the ring using a first-order formula which is independent of the domain.
