    Polar and dispersion force contributions to the total surface free energy of wood (1978)

    Notes: Summary Mathematical models for the polar and dispersion force contribution to the total surface free energy of a solid are reviewed. Experimentally, the geometric-mean and harmonic-mean models are compared for the surface of Douglas-fir wood. Data for both models compare favourably with results from the literature for other man-made and naturally occurring polymeric surfaces. Arguments are offered favoring the use of the harmonic-mean model for characterizing the surface of wood.

    The effects of aging and extraction on the surface free energy of Douglas fir and redwood (1979)
    Springer

    Notes: Summary The effects of aging and extraction on the polar and dispersion components of the surface free energy of redwood and Douglas-fir were investigated. Extracted Douglas-fir and extracted and unextracted redwood have similar dispersion and polar force contributions to the total surface free energy, with the polar forces marginally predominant. Unextracted Douglas-fir has predominantly dispersion forces, an observation probably related to low or nonpolar extractives in this species. Loss of surface free energy with aging appears to be related to environmental rather than wood factors.

    Description / Table of Contents: Zusammenfassung In Anlehnung an die vonReynolds undHower (1970) sowie vonPerry undHower (1970) aufgezeigten Untersuchungsmethoden wurden an Beispielen von bohrproben tertiärer Feinkornsedimente aus dem Wiener Becken Untersuchungen zur Identifizierung und quantitativen Erfassung von Illit-Smektit Mixed-Layer-Phasen durchgeführt, wobei die Behandlung bzw. Ausschaltung von Störeffekten durch detritäre Mineralanteile im Rahmen dieser Methoden in den Vordergrund der Arbeit gestellt wird. Die durchwegs tonigen Silten entsprechenden Proben enthalten in der Fraktion kleiner 0,2 Mikron im wesentlichen Glimmer, Kaolinit und als quellfähige Phase Illit-Smektit, die mit zunehmender Teufevon einer Mischphase mit zufälliger Ordnung und 75% Smektit-bzw. 25% Illitanteilen zu einer geordneten Mixed-Layer-Bildung von 20% Smektit und 80% Illit überleitet. Da die Zusammensetzung der Proben hinsichtlich der Verbreitung von Illit-Smektit, Glimmer und Kaolinit keine Veränderungen aufweist, können Beeinflussungen der beiden zuletzt genannten Phasen im Zuge des Illitisierungsprozesses ausgeschlossen werden. Die zur Illitbildung erforderliche Zufuhr von Kalium und Aluminium erfolgte demnach auf Kosten der Nicht-Ton-Minerale.
    Notes: Summary With reference to the previously published papers byReynolds andHower (1970) andPerry andHower (1970) pelitic sediments from bore hole samples from the Tertiary sequence of the Vienna Basin have been studied to investigate the layer silicate assemblages and to carry out a quantitative estimation of the mixed-layering in the illitesmectite mixtures. Beside these problems one of the primary purposes of this paper is to indicate how interfering reflections from detrital layer silicates can be handled and resolved from diffraction patterns. The samples correspond to clayey silts. Within the less than 0.2 micron fractions they essentially contain mica, kaolinite and illite-smectite as expandable phase. Dependent on depth the composition of these mixtures is intermediate between an interstratified mixed layer phase consisting of about 75 percent smectite layers and 25 percent illite and an ordered mixture which contains about 20 percent smectite and 80 percent illite layers. Since the mineral components maintain essentially constant portions throughout the samples, mica and kaolinite do not enter the illitization reaction. The necessary potassium and aluminum ions were derived from the nonclay constituents.
