Filtration tests were designed with fixed filtration durations and varying relaxation lengths to study the influence of relaxation time on flux recovery and fouling removal.
Chemists and physicists use relaxation effects to study processes that take only a fraction of a second.
Together, these considerations have motivated our interest in the utility of fluorine relaxation parameters to study ligand receptor interactions.
For example, Nieto and Pimentel [6] extended a second-order thermostat model to the fractional model; Ding and Jiang [7] used waveform relaxation methods to study some fractional functional differential equation models.
A particular research emphasis were placed on employing the dielectric relaxation technique to study the dielectric constant, dielectric loss and electric modulus (M″) of the fluorinated alicyclic-functionalized polyimide film FPI-4 and its control sample NPI-4.
This research demonstrates the possibility of using NMR relaxation spectroscopy to study phase transformations of water in gas hydrate systems at temperatures below 273 K, including the region of their metastable states on the P T phase diagram below the ice hydrate gas equilibrium pressure.
Epoxy films were subject to various successive loading unloading cycles including elongation, recovery, annealing, and stress relaxation in order to study the reversibility of the orientation during relaxation processes.
Nuclear Magnetic Resonance NMRR) methods (imaging and relaxation time) allow to study the water content and the pore size distribution in cementitious materials.
In an effort to improve our understanding of the structural changes during ultrasonic treatment, proton NMR transverse relaxation was used to study butyl rubber gum before and after ultrasonic treatment, and ultrasonically devulcanized unfilled butyl rubber.
A new test, known as antistress relaxation, allows us to study, exclusively, the anelastic deformation, i.e. one which is recoverable with time, of various polymers over a wide range of stresses and temperatures until the yield flow point is reached.
