In this work, we investigated the use of a homogeneous Al-doped zinc oxide (AZO) buffer layer to improve the performance of an organic light-emitting diode (OLED) device fabricated on an AZO anode. For this, 10-nm-thick AZO buffer layers with Al doping concentrations of 3.1, 4.1, and 5.1 at % were grown on 140-nm-thick AZO anode films containing 2.1 at % Al by atomic layer deposition. The elect...

Density functional theoretical method has been used to investigate the IR spectrum, heat of formation and thermal stability of a new energetic material, viz., 2,5,2'-triazido-1,1'-azo-1,3,4-triazole. The detonation velocity and pressure are evaluated using the Kamlet-Jacobs equations, based on the theoretical density and heat of formation. The bond dissociation energies for the weakest bonds ha...

An investigation of the migration of 3-chloro-p-toluidine hydrochloride (CPTH) on treated rice baits to soils in Louisiana rice fields was completed. The persistence of free CPTH in these soils was evaluated with field and laboratory experiments. These soils were also screened for the presence of CPTH degradation products. Soils treated with CPTHfortified rice bait and aqueous solutions of CPTH...

It is well known that a lot of organic polymers of liquid crystals containing azo-groups exhibit optical anisotropy after polarized UV light irradiation. In recent year, optical properties of anisotropic nanoparticles in polymers of non-crystalline solid being regularly aligned by external mechanical or magnetic stimulus have been studied with polarized fluorescence spectroscopy and Bragg refle...

Azo compounds have high exothermic characteristics and low thermal stability, which have caused many serious thermal accidents around the world. In general, different locations (e.g., equatorial or polar regions) have different UV intensities. If the azo compound exists in an inappropriately stored or transported condition, the decrease in thermal stability may cause a thermal hazard or ageing....

A new nano-sized cobalt(II) coordination polymer, (CoL1).0.5DMF.1.5CH3OH(1); [H2L1 = 5-(4-Carboxy phenyl azo) salicyilic acid] has been synthesized by a sonochemical method. The thermal stability of compound 1 was studied by thermo- gravimetric and differential thermal analyses. Nano-structure of this coordination polymer was characterized by elementa...

In 1932, 1933, and 1934 Yoshida5' 6, 7,8,9 announced the production of liver-cell tumors in the white rat after prolonged feeding with o-aminoazotoluene (2-amino-5-azotoluene). This compound is dosely related to the azo dye, Scharlach R, and is structurally unlike any of the carcinogenic hydrocarbons of the phenanthrene series. Aside from structure, the compound has aroused considerable interes...
