Abstract: A new phosphorescent iridium metal with cyclometalated and dimethyl carboxylate bipyridine ligands complex 1 was synthesized and characterized. The ester functional were designed and connected as amine recognition group. The UVVis absorption and luminescence properties of complex 1 were investigated with amine. The result show that complex 1 exhibited high selectivity and efficient signaling behavior n-butylamine in acid catalyst.

Abstract: Many parameters are involved in reduction process but carbon availability, process temperature and process time hold the role. This research conducted to find the relation effects of three main factors mention previously. This research used lateritic rocks from Sebuku Island as the iron source and coal as carbon source. Particle size with the highest Fe content is used for reduction process. Variations in reduction process made in mass ratio, process temperature, and process time. The mass ratios are 1:4 and 1:5. The process temperatures are 900^OC and 1000^OC. Process times are 10, 20, and 30 minutes. Characterization process used XRD and XRF. The results show that carbon availability is important and combinations of higher carbon supplies and process temperature are able to prevent further oxidation.

Abstract: Several surfactants were studied in cemented carbides ball milling in this paper by analyzing cemented carbides mechanical properties and SEM images. Appropriate surfactants used in ball milling were selected to replace commonly used surfactant, stearic acid. Impacts of surfactants on hardness, magnetic force and magnetic saturation were also discussed. Oleic acid and AEO-3 as the better surfactant than stearic acid were selected after experiments. How containing oxygen compound affects the cemented carbide mechanical property cannot be recommended at this stage; further investigations are required.

Abstract: Distributions of the electrode information within cavities are much more complex than simulation results. In this paper, a novel set of experiments scanning real potential variations inside cavities under current control were employed to characterize local electrochemical information. Wide variation-fluctuations of electrode potentials have been experimentally revealed. Furthermore, combined with the theoretical analysis and measurement results, kinetic parameters range inside cavities can be indirectly derived.

Abstract: The purpose of this work was to study coating process of high dispersion silver particles on short single-walled carbon nanotubes (Short-SWCNTs) by electroless plating method with an assistance of ultrasonic agitation. The silver-coated carbon nanotubes were prepared and characterized by Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray Spectroscopy (EDS). The results revealed that silver particles with average sizes of 42±0.006 nm, 58±0.008 nm and 59±0.005 nm were achieved using ultrasonic-assisted electroless plating time of 15 min, 30 min and 45 min, respectively. The silver particle size was increased with increasing electroless plating time. Besides, the ultrasonic agitation promoted well dispersion and homogeneity of silver particles on the surface of carbon nanotubes.

Abstract: In this study, we fabricated fibers with nanoporous structure via needleless electrospinning with a rotating disc from a ternary system of solvent/nonsolvent/poly (caprolactone) (PCL). PCL was dissolved in a mixture solution of dichloromethane (DCM) and N,N-dimethylformamide (DMF) with a certain ratio. During disc-electrospinning, the volatile DCM would evaporate speedily, cooling down the surface of polymer jets, which condensed the water around. After the evaporation of nonsolvent DMF and water, irregular pores were observed both on the surface and the internal part of the fibers.

Abstract: In the present study, we fabricated the CNT-porous ZnO composite by Microwave Plasma Jet Chemical Vapor Deposition (MPJCVD) System. The morphology and characteristics of the CNT-porous ZnO were examined by SEM, EDS and Raman spectrometer. Finally, a few carbon content was found to exist within the CNT-porous ZnO nanocomposite.

Abstract: In this paper, study of preparation and testing of polymer nanocomposites (PNC) based on polypropylene matrix and montmorillonite nanofillers is described. Samples were prepared by twin-screw extrusion and injection molding to final shape. Changes of basic properties of these PNC ́s were tested and described in main part of this article.
