    Maillard Reaction in Glassy Low-Moisture Solids as Affected by Buffer Type and Concentration (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 63 (1998), S. 0

    Notes: This study's objectives were to investigate the effects of buffer type and concentration on the kinetics of the Maillard reaction in low-moisture solids. Glucose loss and brown pigment formation were evaluated in low-moisture glassy systems obtained by lyophilizing solutions containing various concentrations of phosphate or citrate buffer at pH 7 and 25°C. Rate constants for glucose loss decreased as buffer concentration increased, suggesting that a change in the system pH had occurred. Rate constants for browning increased with increasing phosphate buffer concentration and decreased with increasing citrate concentration. Phosphate buffer appeared to catalyze later pathways of the Maillard reaction.

    Glycine Loss and Maillard Browning as Related to the Glass Transition in a Model Food System (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 63 (1998), S. 0 
    Details
    ISSN: 1750-3841

    Notes: The effects of water activity and the glass transition on the rate constants for glycine loss and brown pigment formation due to the Maillard reaction were evaluated in a model food system. Equimolar glucose and glycine were incorporated into amorphous polyvinylpyrrolidones of various molecular weights and moisture contents. Glycine loss and brown pigment formation were quantified during storage at 25°C. At constant water activity, rate constants were higher in systems with lower glass transition temperatures. Glycine rate constants decreased upon matrix collapse, but browning rate constants were not affected by collapse. Changes associated with the glass transition influence bimolecular reactions and should be considered during product formulation and shelf-life testing.

    A molecular-dynamics simulation study of the adsorption and diffusion dynamics of short n-alkanes on Pt(111) (1994)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 101 (1994), S. 11021-11030

    Notes: Using molecular-dynamics studies and static potential-energy minimization, we have resolved the mechanisms by which n-alkanes (ethane through n-decane) diffuse on a model Pt(111) surface in the low-coverage limit of a single adsorbed molecule. Our simulations reproduce all of the experimental trends seen for the adsorption and diffusion of C3–C6 on Pt(111) and Ru(001). The short alkanes (C2–C8) behave as rigid rods and their motion involves coupled translation and rotation in the surface plane. For this series, there is a linear increase of the diffusion barrier with the molecular chain length. We have analyzed the compliance of the motion of the assumptions of a nearest-neighbor hopping model. Although hopping motion can be observed for all of the molecules at sufficiently low temperatures, the hopping involves a significant fraction of long jumps. As the temperature increases, the adsorption becomes virtually delocalized. Despite the extensive deviations of the motion from the assumptions of a nearest-neighbor hopping model, the static diffusion-energy barriers, arising from the minimum-energy path for hops between nearest-neighbor binding sites, agree well with those obtained from the tracer-diffusion coefficients for butane, hexane, and octane. For these molecules, multiple-site hops and long flights appear to influence the values of the preexponential factors, which are too large. Neither the diffusion barrier nor the preexponential factor for ethane agrees well with theoretical estimates. We attribute these discrepancies to the smallness of the static diffusion barrier and/or the existence of unique dynamical behavior for this molecule. Due to the increased difficulty of in-plane rotation and increased mismatch between the geometries of the molecule and the surface, the diffusion barrier for n-decane drops below that for n-hexane. The characteristic mechanism of motion for n-decane involves significant C–C–C bond-angle bending. © 1994 American Institute of Physics.

    Effects of environmental conditions on cell growth and poly-β-hydroxybutyrate accumulation in Alcaligenes eutrophus (2000)
    Springer

    Notes: Abstract Influences of the control of glucose and oxygen concentrations on cell growth and poly-β-hydroxybutyrate (PHB) accumulation in Alcaligenes eutrophus were studied. Glucose affects both biosynthesis and glycolysis directly and the other pathways indirectly. PHB accumulation could also be stimulated under oxygen limitation conditions, but the final PHB content within the cells was less than in the case of nitrogen limitation. When the culture was shifted from the PHB accumulation state to balanced growth conditions, PHB degradation occurred in the cells. The cell growth was inhibited by high PHB content within the cells.

    Notes: The recrystallization behavior of high strength automobile steel sheets (ZJ590L) developed by CSP technology is studied in this paper. The effect of the deformation temperature, reduction on the austenite grain size and the recrystallized fraction of ZJ590L steel during hot deformation has been investigated. Technique of test and analysis includes preparing stepped test piece and quantitative metallograph. The mechanism of austenite microstructure refinement has been discussed, which provides valuable references to set parameters of controlled rolling and controlled cooling process. The analysis shows that the austenite grain size fines with the increase of deformation temperature and reduction, and the recrystallized fraction increases. When the deformation temperature is above 1000℃ and reduction exceeds 40%, complete recrystallization can be obtained

    Notes: In this research, applications of different TiO2 electrode structures on Dye-Sensitized Solar Cellwere investigated. The different TiO2 electrode structures include: (1) synthesis of TiO2 nano-particlesand TiO2 film electrode by sol-gel and spin-coating method; (2) fabrication of the TiO2 film electrode byRF Sputtering; (3) fabrication of the rod TiO2 electrode by photo lithography. X-ray diffraction patternsshow that the best sintering temperature of nano-TiO2 thin film is 500oC, at which TiO2 anatase phaseforms best and the smallest particle-size (8-10 nm) can be obtained. Ultraviolet-visible absorption spectrareveal that the rod TiO2 electrode with TCPP sensitizer adsorbed on has the best optical absorption from400 nm to 700 nm. The results of current-voltage analyses reveal that the solar cell with rod TiO2electrode has higher conversion efficiency than the others. This result also provides clear evidence for thecontact area between TiO2 electrode and TCPP sensitizer plays an important role on the efficiency ofdye-sensitized solar cell

    Experimental Study on the Detection of Surface-Breaking Defects on Metal with the Scanning Laser Line Source Technique (2007)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: The scanning laser line source (SLLS) technique is a novel laser-based inspection methodfor the ultrasonic detection of small surface-breaking defects. The SLLS approach is based onmonitoring the change in laser generated ultrasound as a laser line source is scanning over a defect.It has provided enhanced signal-to-noise performance compared to the traditional pitch-catch orpulse-echo ultrasonic methods. In this paper, an experimental method is presented to detect surfaceacoustic waves (SAW) with polyvinylindene fluoride(PVDF) transducer. The ultrasonic signal isconverted into electric signal by piezoelectricity of the PVDF, which is attached to a micro-knifeedge clamped on a metal device. The SAW are excited by employing a pulsed Nd:YAG laser onaluminum plate with artificial surface-breaking defects. The laser line source is accurately shiftedby the motorized translation stage, while the PVDF is located at a fixed position on the specimen.When the laser line source is scanning over the defect, the ultrasonic signals are monitored,meanwhile the characteristic changes in the amplitude and frequency content are observed.Consequently, the position of the defect can be determined by analyzing the obtained signals. Theexperimental system with high sensitivity provides a detection method of small surface-breakingdefects on metal and gives convincing experimental evidence for the interaction mechanismbetween the SAW and the surface-breaking defects
