  • Moisture Sorption Isotherm Method (.pdf)
    The relationship between water activity (aw) and moisture content at a given temperature is called the moisture sorption isotherm. This relationship is complex and unique for each product due to different interactions (colligative, capillary, and surface effects) between the water and the solid
  • Ensuring Better Control of Granulation
    in mobile liquid films. During wet granulation, liquid is added to the powder mix and distributed as films around and between the particles. There are three states of water distribution between particles. At low moisture levels, the pendular state, particles are held together by surface tension forces
  • MICRO:Tech Emergent
    water-based cleans do not always reach small, high-aspect-ratio features, and their residues are difficult to remove completely. In addition, drying wafers after water-based cleans can damage mechanically weak structures such as MEMS devices and porous low-k dielectrics. To meet the challenges posed
  • MICRO:Extreme Silicon by Peng Sun, p.41 (April '99)
    wafers and faces the evolving defect density requirements of the SIA roadmap, nonmetallic ionic contaminants on wafer surfaces have become an increasingly important concern. Because such impurities can degrade wafer surfaces, particularly in the presence of adsorbed water, they have detrimental
  • Felt Seals
    saturated and intermittently dried. It is damaged by alkalis. Untreated, it resists oil, greases, waxes, and most solvents. Mechanically interlocked synthetic-fiber felt seals withstand attack by strong acids and bases and are stable in water, common fuels, lubricants, hydraulic fluids, and solvents
  • "Hare's Looking at You, Kid. "
    which piece it attaches to, a microfabrication technique known as self-assembly. Capillary forces the same forces that drive water upward in plants pull the pieces together. The prototype lens does not correct the wearer 's vision, but the technique could be used on corrective lenses, Parviz says

  • Capillary Electrophoresis
    AccuSep polyimide fused-silica capillaries ( Waters , Milford, MA) of dimension 60 cm × 50 m ID were used.
  • Stone in Architecture
    by capillary water absorption.
  • Progress in Polymers in Concrete
    In our present research, the results exhibit that as the polymer/cement ratio (mp/mc) increases from 0% to 5%, the reduction in the capillary water absorption and the penetration depth of water into mortar is significant.
  • Introduction to Phytoremediation of Contaminated Groundwater
    As stated earlier, the magnitude of the ETp at a site provides an estimate of the atmospheric demand for water, which can be supplied by surface water, soil moisture, cap- illary water , and groundwater.
  • Unsaturated Soil Mechanics in Engineering Practice Complete Document
    Let us consider the vertical force equilibrium of the cap- illary water in the tube shown in Fig. 2.40.
  • Stone in Architecture
    In contrast, the maximum pores in S0 are smaller than 0.1 μm, which cannot be filled by capillary water absorption.
  • Encyclopedia of Agrophysics
    Bypass flow has previously been defined as the flow of “free” (i.e., non- or over- capillary ) water along macropores into and through an unsaturated soil matrix (Bouma, 1981; van Stiphout et al., 1987); in the field bypass flow often starts when …

    These range from ground water flow, to water intercepted by vegetation, water intercepted by surface depres- sions, capillary water rise in the soil, and water stored in the tis- sue of plants to name a few.
    Free water which freezes. at -1.5 deg. C. and unfree water which does not function as a solvent and which he divides into (a) capillary water which freezes at -1.11 deg. C. and, (b) combined water which does not freeze …
