Anti-Microbial activities of two Platinum(II) complexes bearing ethyl eugenoxyacetate and synthesis, structure of [PtCl(ethyl eugenoxyacetate-1H)(morpholine)]
Abstract: Two organo-metallic complexes of platinum(II), [PtCl(Eteug-1H)(C9H7N)] (P1), [Pt(Eteug-1H)(OC9H6N)] (P2), have been experimented on anti-microbial activity for the first time. P1 has activity against L.fermentum and B.subtilis bacterias with the IC50 values of 165.05, 220.58 µg/mL, respectively, P2 exhibits higher cytotoxicity on B.sub...

Study on the chemical composition, Biological activity and Physico-Chemical indicators of the weft-peel oil of Bac Giang oranges extracted by cold-pressing method
Abstract: The oil of Bac Giang orange weft peels were obtained by cold-pressing method and dried with Na2SO4. By using the GC-MS method, 33 components of the oil were estimated by comparing their retention times and molecular weights with the standards. In particular, there were 15 hydrocarbons such as monoterpenes: 53.51%, sesquiterpenes: 7.19%...

Structural simulation of Mg2SiO4 under compression
Abstract: The microstructure in Mg2SiO4 glass under high compression is studied by molecular dynamic method. This work revealed the correlation between pair radial distribution functions (PRDF) of Si-Si pair and bond angle distribution (BAD) of Si-O-Si and focus on clarifying the split peak of Si-Si PRDF. Moreover, visualizing the bonds of Si-Si...

Fabrication and characterization of CoFe2O4/CoFe2/SiO2 nanocomposite particles
Abstract: The CoFe2O4/CoFe2/SiO2 nanocomposite particles were synthesized using a sol- gel method and calcination in hydrogen. The magnetic properties and structure of nanocomposite particles calcinated at 600 oC and 900 oC in range of calcination time from 1 h to 4 h were investigated. The phase composition, surface morphology and magnetic prop...

Study of supporting electrolytes of KCl-Acetate buffer - NH4Ac for simultaneous determination of Zn2+, Cd2+, Cu2+, Pb2+ in acid mine drainage in Mao Khe, Quang Ninh by anodic stripping voltammetry at hanging mercury-drop electrode
Abstract. The simultaneous determination of Zn2+, Cd2+, Cu2+, Pb2+ in acid mine drainage (AMD) by differential pulse-anodic stripping voltammetrics (DPASV) with high sensitivity, selectivity, and accuracy is difficult because of many influential factors in the waste-water. This paper presents the results of studying supporting electrolyte for si...

Quantum condensation in a two-component system of atoms
Abstract. The Cornwall-Jackiw-Tomboulis (CJT) effective action at finite temperature is applied to study the quantum condensation of a two-component system of atoms. We derive the renormalized effective potential in the Hartree-Fock approximation, which preserves the Goldstone theorem. Numerical results show that there exist quantum condensation...

Structural, optical and electrical properties of undoped and al doped-ZnO films for use in photovoltaic devices
Abstract. ZnO films are deposited on glass substrates using a sol-gel spin coating method. To investigate the influence of Al doping concentration on structural, optical and electrical characteristics of films, Al doping concentrations are varied from 0% to 5%. The surface morphology, structure and optical transmittance characteristics of the fi...
