the polarographic reduction of aromatic carbodiimides in anhydrous aprotic solvents goes through a carbene intermediate by a diffusion controlled process in two one-electron steps. the first step is the rate-determining step and converts the carbodiirnide to a radical anion (6) that reduces further by a fast one-electron step to a carbene dianion intermediate (7). this abstracts an oxygen, alon...

The formation and entrapment of tris(8-hydroxyquinoline)aluminum (Alq₃) molecules on the surface of anodic porous alumina (APA) immersed in an ethanol solution of 8-hydroxyquinoline (HQ) were investigated by absorption, fluorescence, and Raman spectroscopies. The effects of the selected APA preparation conditions (galvanostatic or potentiostatic anodization method, anodizing current and voltage...

The corrosion inhibition potential and efficacy of 2-hydropyrimidine-2-thione derivative on mildsteel in 0.5 M sulfuric acid solution was investigated using electrochemical polarization and FTIRspectroscopic techniques. In addition, docking studies were carried out as theoretical investigationof adsorption inhibitor on iron surface. The results of polarization studies indicate...

Estimation of forest biomass has received much attention in recent decades. Airborne and spaceborne (SAR) have a great potential to quantify biomass and structural diversity because of its penetration capability. Polarizations are important elements in SAR systems due to sensitivity of them to backscattering mechanisms and can be useful to estimate biomass. Full Polarimetric Synthetic Aperture ...

In this research, electrodeposition procedure was utilized for the synthesis of a new composite polymer: N-methylpyrrole–Triton–X100/N, N,N-diethylaniline (NMPY-TRX100/NNDEA) used as coating on carbon steel type OL 37 electrode corrosion protection. The surfactant Triton–X100, dopant ion throughout process electropolymerization, had significant impact protection by impeding penetration corrosiv...
