Analysis of gamma-amino butyric acid in the germinated brown rice by pre-column derivatization with 2, 4-dinitrofluorobenzene
Hyok-Chol Ri, Jong-Ho Yun, Kye-Ryong Sin +1
This paper reports the analytical method for gamma-amino butyric acid in the germinated brown rice by liquid chromatography. GABA was derivatized by pre-column derivatization with…
Determination of Trace Moisture Content in Dimethylacetamide by Gas Chromatography
Yong-A Choe, Chan-Hyon Han, Kye-Ryong Sin
Dimethylacetamide is used as a solvent in polymer processing and moisture in DMA affects the morphology and mechanical properties of the polymer products. This paper describes a me…
Bonding charge distribution analysis of molecule by computation of interatomic charge penetration
Yong-U Ri, Young-Hui Pyon, Kye-Ryong Sin
Charge transfer among individual atoms in a molecule is the key concept in the modern electronic theory of chemical bonding. In this work, we defined an atomic region between two a…
Influence of temperature and humidity on the detection of benzene vapor by piezoelectric crystal sensor
Chan-Hyon Han, Yong-A Choe, Jong-Ho Yun +1
The effects of temperature and humidity on the estimation of air pollution by benzene by using the piezoelectric crystal gas sensor were studied. Polyvinylchloride films were used…
Relative Distribution of Water Clusters at Temperature (300-3000K) and Pressure (1-500MPa)
Yong-U Ri, Chang-Sob Kwak, Kye-Ryong Sin
At 300-3000K and 1-500MPa, variations of relative contents for small water clusters (H2O)n (n=1~6) were calculated by using statistical mechanical methods. First, 9 kinds of small…
Study on the Electronic Structure and Stability of Some OPE(oligo-phenylene-ethynylene derivative)-RE3N@C80 Dyads by PM7
Kye-Ryong Sin, Sun-Gyong Ko, Hong-Gol O +1
In this paper, we investigated the electronic structure and stability of some mesomorphic OPE-RE3N@C80 dyads from the oligo-phenylene-ethynylene derivatives (OPE) and the trimetall…
Study on the Electronic Structure and Stability of Some Endohedral Fullerenes - RE3N@C80 (RE = Sc, Y, La) by PM7
Kye-Ryong Sin, Sun-Gyong Ko, Kwang-Yong Ri +1
In this paper, we investigated the electronic structure of some endohedral fullerenes containing rare earth nitride and the stability of their benzyne-adducts by PM7, the semiempir…
