    Notes:
    Abstract Ultrasonic propagation characteristics of collagen solutions are reported. The concentration dependences of the various ultrasonic parameters of the solvent (acetic acid) and the solute (collagen) are compared. The ultrasonic velocities for acetic acid and collagen are comparable, while the attenuation is very high in collagen solutions. The adiabatic compressibility and the free length in collagen solutions decrease with increasing concentration. The relaxation time increases rapidly with concentration of collagen, unlike that for acetic acid.

    Notes:
    Abstract The mechanical properties and fracture behaviour of dry and native elastoidin are studied as a function of strain rate, and the plastic set behaviour of the dry elastoidin is found to be sensitive to strain rate. The results are correlated with the scanning electron microscopy of the fractured ends of dry and native elastoidin. Broken ends of dry elastoidin, fractured at a strain rate of 10.0 min−1, appear blunt and under the same conditions the native specimen's ends appear sharp.

    Notes:
    Abstract The strain-rate dependence of collagen fibre, a viscoelastic material, was studied both in the native and dry conditions. The strain rate effect was observed in the stress-strain, plastic set behaviour of both dry and wet collagen fibres. Fractured ends of the broken fibres, observed using scanning electron microscopy, showed that the fracture behaviour was different at high and low strain rates. The results are compared with those for elastoidin.

    Notes:
    Poly(acrylonitrile) (PAN) was solution blended with poly(n-butyl methacrylate) (PnBMA) in various proportions. Compatibility in these blend systems was analyzed using ultrasound. The ultrasound velocity and attenuation results show that the two polymers formed a compatible blend. Viscosity and other derived parameters like free volume and internal pressure of the blends show that PAN form into an ideal blend with PnBMA in the compositions of 60 : 40 and 40 : 60. © 1994 John Wiley & Sons, Inc.

    Notes:
    Casein was grafted with a binary mixture of acrylonitrile and n-butyl methacrylate. The mechanical properties of the grafted casein films were studied at various extension rates. The fractured surfaces were analyzed using scanning electron microscopy. With the increase in extension rate, the strain at yield increases to a maximum value and then decreases to a limiting value. The stress at yield and the energy at break steadily increase with the increase in the rate of extension.

    Notes:
    Simple stress-strain characteristics of silk do not give sufficient information on the influence of the rate of testing in silk. A methodology is described to quantify individual components of viscoelasticity which clearly brings out the influence of the strain rate on the viscous component of the system. © 1996 John Wiley & Sons, Inc.

    Notes:
    Casein was grafted with mixtures of acrylonitrile (AN) and n-butyl methacrylate (n-BMA). The mole ratios of AN: n-BMA were 0.9:0.1 and 0.8:0.2. The mechanical properties of the grafted casein films were studied under uniaxial and biaxial stress conditions. A reduction in longitudinal stress and elongation at break was observed with the simultaneous application of lateral stress. Scanning electron micrographs of the stretched films (uniaxial and biaxial stress) are also presented.
