    Evaluation of Methods for Measuring Polyphenols in Conifer Foliage (2000)
    Springer
    Journal of chemical ecology 26 (2000), S. 2119-2140 
    Details
    ISSN: 1573-1561
    Keywords: Polyphenols ; condensed tannins ; plant adaptations ; plant–litter-soil interactions ; 13C NMR
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract There is a resurgence of interest in the quantification of polyphenols in plant tissues because of their presumed ecological importance in plant–litter–soil and plant–animal interactions. The influence of sample preparation, extracting solvent, foliage quality, and assay method was investigated for the quantification of total phenols and condensed tannins in conifer foliage. Our results suggest that it is not possible to recommend a single optimal protocol for quantification of total phenol and condensed tannin fractions from plant materials. In general, the use of aqueous acetone (50–70% v/v) with freeze-dried materials gave the highest recovery. The Folin-Ciocalteau method for total phenols and the butanol–HCl hydrolysis method for condensed tannins appear superior to other common assays tested. There were large differences (1.4–2.2 times) in the reactivity of purified condensed tannins among species, indicating the importance of an appropriate standard for polyphenol quantification. A solid-state 13C NMR method with an improved "interrupted decoupling" pulse sequence yielded the highest concentrations for condensed tannins. Assuming that 13C NMR provides an accurate measure of total condensed tannin, the other extraction/assay methods used in this study recovered 50–86% of the condensed tannin fraction. The recovery rate is correlated with the nitrogen content of the foliage, which suggests that the formation of protein–tannin complexes may limit the extractability of condensed tannins. While 13C NMR condensed tannin values may give the best value for total condensed tannin concentrations, the water-soluble fraction may have the greatest physiological and/or ecological significance.

    Flow regimes of the three-phase circulating fluidized bed (1995)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 41 (1995), S. 267-271 
    Details
    ISSN: 0001-1541

    Notes: Gas-solids circulating fluidized beds have been successfully used in catalytic cracking of heavy oil, coal combustion, and some metallurgical and physical processes (Grace, 1990). Gas-liquid-solids fluidized beds are operated mainly in conventional fluidization regimes without solids circulation or in the transport regime with low solids holdups (less than 5%) (Fan, 1989). A circulating/fast fluidization regime, however, has not been studied. A three-phase circulating fluidized bed has several potential applications in biochemical and chemical processes. Three-phase fluidized-bed bioreactors generally use light and small particles (Berk et al., 1984). Circulating operation can promote solids mixing and increase product throughput per unit bed cross section, while high shear stress can promote biofilm renewal (Pirozzi et al., 1990). In three-phase hydrotreating reactors, solids catalysts lose their activity due to the deposit of metal and coke on the surface. Circulating operation not only regenerates deactivated catalyst continuously using accompanying downcomers but also transfers heat to and from the reactor. This article discusses the flow regimes of the three-phase circulating fluidized bed.

    Nylon/Kevlar composites. II: Investigation of interfacesParts of this work have been presented at the IUPAC MACRO '90. (1991)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: The aim of this article was the investigation of the fiber-matrix interface of nylon/Kevlar composites. Both washed fibers and chemically treated fibers were used as reinforcements for nylon-6 and nylon-l1. Improvements of the mechanical properties were related to the increase in the nucleating abilities of the fibers, which was modified considerably by chemical treatments. Differential Scanning Calorimetry (DSC), X-Ray diffraction, optical microscopy, and scanning electron microscopy were used to investigate the interface between the matrix and the fibers. The chemical treatments performed on the Kevlar fibers were found to affect the size of the transcrystalline zone and its crystal structure.

    Notes: This paper deals with the characterization of the mechanical properties of Kevlar/nylon composites. It has been shown that addition of up to 5 % Kevlar to nylon matrices (nylon-6, nylon- 11, and nylon-6,6) is possible by melt blending, and results in improved mechanical properties as compared to the pure matrix. In order to increase the interfacial adhesion of the fibers and the matrix, various chemical treatments were performed on the fibers: surface hydrolysis, succinyl chloride reactions and suberoyl chloride reactions. These were shown to affect significantly the mechanical properties, and depending on the treatment Of the fiber, improvement or deterioration of the mechanical properties could be observed. The effect of humidity has also been investigated, and it was shown that the addition of Kevlar greatly reduced the susceptibility of the tensile modulus to humidity.
