DOI: 10.1007/s10570-019-02278-3
Abstract: A thorough rheological study of the behavior of cellulose nanocrystals (CNC) in water was undertaken, focusing on the main characteristics of rod-like suspensions that allign under flow and can display liquid crystal behavior at rest,… read more here.

Abstract: Cardiovascular mechanical stresses trigger physiological and pathological cellular reactions including secretion of Transforming Growth Factor β1 ubiquitously in a latent form (LTGF-β1). While complex shear stresses can activate LTGF-β1, the mechanisms underlying LTGF-β1 activation remain… read more here.

Abstract: We have determined the susceptibility of T4 DNA (166 kilobase pairs, kbp) to fragmentation under steady shear in a cone-and-plate rheometer. After shearing for at least 30 min at a shear rate of 6000 s -… read more here.

DOI: 10.1122/1.4990049
Abstract: Oscillatory and steady shear of cellulose in 1-ethyl-3-methylimidazolium methylphosphonate {[EMIm][P(OCH3)(H)O2]} were studied for cellulose concentrations from 0.017 to 10 wt. %, spanning the dilute, semidilute unentangled and entangled regimes. The overlap concentration of our cellulose in… read more here.

DOI: 10.3390/polym9060205
Abstract: The exponential Phan–Tien and Tanner (PTT), Giesekus, Leonov, and modified extended Pom–Pom (mXPP) differential constitutive models are evaluated in two ways: with regard to steady shear characteristics and with regard to large amplitude oscillatory shear… read more here.
