Published: May 2005

AbstractDynamic surface properties of aqueous solutions of cationic fluorous surfactant CF3CF2CF2O(CF(CF3)CF2O)2CF(CF3)CONH(CH2)3N+(C2H5)2CH3I‐ (abbrev. FC‐4 ) were reported. The critical micelle concentration (cmc) (3.6×10‐5 mol/L) and equilibrium surface tensions γeq were measured by Krüss K12 tension apparatus. Dynamic surface tension γ(t) was measured in the range of 15 ms to 200 s using the MBP tensiometer. The surface excess Γ, as a function of concentration, was obtained from equilibrium tensiometry using the Gibbs equation. Data from these experiments were combined to analyze the γ(t) decays according to the asymptotic Ward and Tordai equation. The results show that at the initial adsorption stage, the dynamic surface tension data were all consistent with this diffusion‐controlled mechanism, and at the end of the adsorption process, there were some evidences for an adsorption barrier, suggesting a mixed diffusion‐controlled adsorption mechanism. Using measured quantities, the barrier strength was estimated as between 25 and 35 kJ/mol at 25 °C. The surface pressure plays an important role in contributing to the barrier.

Authors: Rong Guo , Xun Wei , Tian‐Qing Liu 
Published: May 2005

AbstractIn the system of SDS/n‐C5H5OH/n‐C7H16/H2O with the weight ratio of SDS/n‐C5H11OH/H2O system at 5.0/47.5/47.5, the upper phase of the system was W/O microemulsion, and the lower phase was the bicontinuous microemulsion. When the n‐heptane content was less than 1%, with the increase of the n‐heptane content, the capacitance (Co, Cod) in the upper phase (W/O) dropped, the capacitance (CBI, CBId) in the lower phase (BI) raised. At the same time, the W/O‐BI interfacial potential (ΔE), capacitance (Ci), and charge‐transfer current (ict) decreased. After the n‐heptane content reached 1%, with the increase of the n‐heptane content, ΔE, Ci and ict demonstrated no significant change.

AbstractReaction of anhydrous YbCl3with 2 equiv. of sodium 2,4,6‐tri‐tert‐butylphenoxide (ArONa, Ar=C6H2‐t‐Bu3‐2,4,6) and 2 equiv. of potassium diphenyl amide in THF afforded the first bis(aryloxo) amido‐lanthanide complex of (ArO)2Yb(NPh2)2K(THF)4(1). In1, the ytterbium and potassium were bridged via diphenyl amido ligands. The ytterbium metal center was coordinated to two oxygen atoms of aryloxide ligands and two nitrogen atoms of diphenyl amido ligands in a conventional distorted tetrahedral fashion, while the potassium interacted in η2‐fashion with two phenyl rings of the diphenyl amido ligands besides four THF molecules.1displayed moderate catalytic activities for the polymerization of methyl methacrylate and acrylonitrile.
Interaction of Methylamine with Highly Siliceous MFI, FAU and FER‐type Zeolites
Authors: Ai‐Jie Han , Yu Zeng , Juan Guo , Yue‐Fang Huang , He‐Yong He , Ying‐Cai Long 
Published: May 2005

AbstractThe adsorption of methylamine on highly siliceous MFI, FAU and FER‐type zeolites was investigated with XRD, FT‐IR, Raman, 13C and 29Si MAS NMR, and compared with the adsorption of methanol. As the adsorption of the amine, the relative intensity of XRD peaks of the zeolites has been changed significantly, the high‐resolution 29Si MAS NMR peaks have been broadened and shifted to low field, and the resonance of SiOH groups has appeared. The vibration of NH has been shifted to low frequency and CN vibration moved to high frequency in the IR spectra, and the 13C resonance peak broadened and shifted to high field for the adsorbed amine. The facts reveal an associating interaction between the perfect framework of the zeolites and the adsorbed methylamine with hydrogen bonds, leading to the formation of SiOH groups and the high desorption temperature of the methyl‐amine from the zeolites.
Ratiometric Fluorescent Receptors for Monosaccharides Based on the Intramolecular Charge Transfer in p‐Dialkylaminobenzanilides
Authors: Li‐Hong Liu , Han Zhang , Xuan Zhang , Yun‐Bao Jiang 
Published: May 2005

AbstractTwo dual fluorescent receptors (1 and 2) for monosaccharides based on 4‐dialkylaminobenzanilides (alkyl=methyl and n‐butyl) containing boronic acid group at the amido aniline were synthesized and their spectral properties were investigated. These receptors exhibited dual fluorescence with the long‐wavelength band displaying strong solvent‐polarity dependence, indicating the occurrence of the excited‐state intramolecular charge transfer (ICT). With increasing pH value in aqueous solutions, the hybridization of the boron atom changed from sp2 to sp3, inducing a decrease in the total fluorescence quantum yield. The experimental results indicated that the anionic form of the boronate group acted as an electron donor and the benzanilide‐like charge transfer was promoted upon hybridization change. In the presence of monosaccharides, the boronic acid in 1 and 2 changed from neutral to anionic form. The intensity of the locally excited (LE) state emission decreased in the presence of sugars while a slight increase in the intensity at the charge transfer (CT) emission occurred. Based on the change in the CT to LE intensity ratios of 1 and 2 due to sugar binding, ratiometric fluorescent assays for monosaccharide sensing were established.

Published: May 2005

AbstractThe cyclic voltammetric (CV) behaviors of NAD+were studied with a multi‐walled carbon nanotubes (MWNTs) modified glassy carbon (GC) electrode. In 0.05 mol/L tris(hydroxymethyl)aminomethane‐HCl (Tris‐HCl) buffer solution (pH=6.9), the MWNTs modified electrode showed high electrocatalytic activity toward reduction of NAD+. The electroreduction of NAD+was an irreversible diffusion controlled process. The cathodic peak current in‐creased linearly with increasing the concentration of NAD+. The influences of scan rate, temperature and concentration were also investigated.
Synthesis of 5,10,15,20‐Tetra[4‐(N‐ethylpiperazinyl)phenyl]‐porphyrin and Its Interaction with DNA
Authors: Can‐Cheng Guo , He‐Ping Li , Xiao‐Bing Zhang 
Published: May 2005

AbstractPiperazinyl‐porphyrin, 5,10,15,20‐tetra[4‐(N‐ethylpiperazinyl)phenyl]porphyrin (TEPPH2), was synthesized based on the special affinity of porphyrin to cancer cells and the antitumor activity of piperazine compounds. Its structure was characterized by UV‐vis and 1H NMR spectra and elemental analysis. A model for the interaction between TEPPH2 and calf thymus DNA was built, and the binding mechanism was investigated by UV‐vis and fluorescence spectra. The results indicated that TEPPH2 could intercalate into the base pairs of DNA strongly. One calf thymus DNA molecule could bind 88 TEPPH2 molecules, and the binding constant K is 8.4×106 L·mol‐1. The binding number and binding constant of TEPPH2 with DNA are higher than those of the known anti‐tumor drugs, tetrakis(4‐N‐methylpyridyl)porphine and the Schiff bases Ca/sal‐his and Ni/sal‐aln.

AbstractUsing highly dilute method and 5‐fold excess of diamine a new acyclic diamine containing pyridine moiety, N,N′‐bis(2‐aminoethyl)‐2,6‐pyridinedicarbamide (1a) was synthesized. Six novel linear polydentate Schiff base ligands containing pyridine and amide moieties, N,N′‐bis[β‐(R‐substitutedbenzalimino)ethyl]‐2,6‐pyridinedicar‐bamide (2a‐2e), where R=H, o‐OH, p‐OH, m‐NO2, p‐N(CH3)2, and N,N′‐bis(γ‐salicylideneaminopropyl)‐2,6‐ pyridinedicarbamide (2f) have been synthesized and characterized by elemental analysis, IR, UV‐Vis, MS and 1H NMR methods. The single‐crystal analysis of 2e showed that it belongs to triclinic system with P‐1 space group and the unit cell parameters: a=11.010(2) nm, b=13.865(3) nm, c=9.6537(19) nm, α=102.77(2) °, β=92.07(3)) °, γ=87.98(3)) °, V=1435.7(5) nm3, Z=2, Dc=1.230 mg·cm‐3, Mr=531.66. In addition, microcalorimetric test of the inhibitory capacities of these compounds for E. coli has shown that they have antibacterial activity to different extent and that of salicylidene Schiff base is the best. The structure‐activity relationship has been primarily discussed.
Microstorms in Cellular Polymers: A Route to Soft Piezoelectric Transducer Materials with Engineered Macroscopic Dipoles
Authors: Wegener Michael , Bauer Siegfried 
Published: May 2005

AbstractCellular polymers can be internally charged by “microstorms” (silent or partial discharges) within the voids of the polymer foam. The resulting material, which carries positive and negative charges on the internal void surfaces, is called a ferroelectret. Ferroelectrets behave like typical ferroelectrics, hence they provide a novel class of ferroic materials. The soft foams are strongly piezoelectric and can be used, in a wide range of applications, as transducers for interconverting mechanical and electrical signals. Herein, an overview is provided on the preparation of cellular polymers by physical foaming (extrusion, biaxial stretching, and controlled inflation by pressure treatments), on their charging by “microstorms”, on their piezo‐ and pyroelectricity, and on analogies to ferroelectrics. Finally, a survey of selected applications is presented.
Energy Transfer in Single Hydrogen‐Bonded Water Molecules
Authors: Bakker Huib J. , Gilijamse Joop J. , Lock Anjan J. 
Published: May 2005

AbstractWe study the structure and dynamics of hydrogen‐bonded complexes of H2O/HDO and acetone dissolved in carbon tetrachloride by probing the response of the OH stretching vibrations with linear mid‐infrared spectroscopy and femtosecond mid‐infrared pump–probe spectroscopy. We find that the hydrogen bonds in these complexes break and reform with a characteristic time scale of ≈1 ps. These hydrogen‐bond dynamics are observed to play an important role in the equilibration of vibrational energy over the two OH groups of the H2O molecule. For both H2O and HDO, the OH stretching vibrational excitation relaxes with a time constant of 6.3±0.3 ps, and the molecular reorientation has a time constant of 6±1 ps.
Power factor improvement of single‐phase diode rectifier circuit by field‐weakening of inverter‐driven IPM motor
Authors: Takahashi Isao , Haga Hitoshi 
Published: May 2005

AbstractThis paper proposes a novel inverter drive system to improve the input power factor of single‐phase diode rectifier. Conventional rectifiers need a high‐frequency switching device and a reactor to improve the input power factor. However, the proposed power converter does not need the switching device, electrolytic capacitor, or reactor. By making many ripples across the DC‐bus voltage, the input power factor can be improved. The proposed system consists of only a single‐phase diode rectifier, small film capacitor, three‐phase inverter, and motor. The proposed system adopts an interior permanent magnet (IPM) synchronous motor. The IPM motor is well known as a high‐efficiency motor and can realize field weakening. The basic ideas of the inverter control method are based on the following operations: the inverter's controlled synchronous with the DC‐bus ripple voltage by field‐weakening method, and direct active power feeding from the source side to the motor without smoothing the DC‐bus voltage. This paper describes that the proposed method can obtain an input power factor of 97.3% by experimental tests, and realizes the goals of small size and long life of the system. © 2005 Wiley Periodicals, Inc.

Study on dependence of AC transport current losses in YBCO‐coated conductors on distribution of critical current density and n value
Authors: Miyagi Daisuke , Tsukamoto Osami 
Published: May 2005

AbstractWe measured AC transport current losses in three kinds of thin‐film YBCO‐coated conductors made by different processes. The results showed that the loss characteristics were different and that some of the conductors did not follow the Norris strip model which is generally believed to well explain the loss characteristics of YBCO conductors. In the paper, an analytical model in which distribution of critical current density and n value of the conductor are taken into consideration is proposed to describe the AC transport current loss characteristics more generally than the Norris strip and elliptical models. It is shown that the analytical model explains well the measured loss characteristics of the three kinds of conductors. © 2005 Wiley Periodicals, Inc.

A dynamic mathematical model and vector block diagrams for class of hybrid‐field synchronous motors
Authors: Shinnaka Shinji 
Published: May 2005

AbstractThis paper proposes a new dynamic mathematical model and new block diagrams for a newly emerging class of salient‐pole hybrid‐field synchronous motors (HFSM) that have rotor field by both permanent magnet and winding. The proposed mathematical model has the following completeness and generality. (1) It consists of three consistent basic equations such as circuit, torque, and energy‐transmission equations. (2) It deals with pole saliency and contains nonsaliency as a special case. (3) It is a dynamic model and contains a static one as a special case. (4) It is established in the general reference frame including stator and rotor reference frames as special cases. The proposed new block diagrams using vector signals for salient‐pole HFSM are established based on the model. It has the following attractive features. (1) It succeeds in realizing clear configurations with physically meaningful vector signals, which are helpful for understanding motor electromagnetic mechanisms and useful for designing controllers for the salient‐pole HFSM. (2) Vector signals utilized as transfer signals between blocks are defined in the general reference frame. Consequently, the vector‐signal block diagrams in the frame can be directly and easily reduced to the ones in such a specific frame as stator and rotor frames. (3) It is compact. Two typical and compact but sufficiently general vector‐signal block diagrams are newly presented. © 2005 Wiley Periodicals, Inc.
