A highly efficient three-phase single drop microextraction (SDME) method is presented by using an organic-aqueous compound droplet. A coupling microdevice is designed to produce compound droplets in different sizes conveniently. In this way, the volume ratio of organic phase to aqueous phase in a compound droplet can be significantly reduced. Good operability and droplet stability were observed...
Herein, we report a hybrid polyoxometalate organic-inorganic compound, Na2 [(HGMP)2 Mo5 O15 ]⋅7 H2 O (1; where GMP=guanosine monophosphate), which spontaneously assembles into a structure with dimensions that are strikingly similar to those of the naturally occurring left-handed Z-form of DNA. The helical parameters in the crystal structure of the new compound, such as rise per turn and helical...
A quantum chemical study of the corrosion inhibition properties of some organic inhibitormolecules, pyridine, 2-picoline, 3-picoline, 4-picoline, 2, 4-lutidine at the aluminum surface inhydrochloric acid (HCl) was carried out. The models of the inhibitors adsorption on the Al-surfacewere optimized with the HF and B3LYP level using the 6-31G and LANL2DZ basis sets fromthe program package Gaussia...
