In this study, geometrically modified microchannels fabricated using a stereolithography technique are employed to analyze micromixing of polymeric solutions. Experimental and numerical analyses were conducted evaluate the qualitative quantitative validity Newtonian fluid flow inside channels. An in-house image processing code was used dye concentration distributions resulting from complex tran...

In this work, nanocomposite (NC) hydrogels based on polyacrylamide/chromium triacetate were prepared at different reaction mixture (gelant) volumes and their crosslinking process and viscoelastic behaviors were studied. The X-ray diffraction (XRD) patterns taken from the NC hydrogels containing laponite nanoparticles did not show any distinct characteristic basal reflection for all of the NC hy...

The generation of shear waves from an ultrasound focused beam has been developed as a major concept for remote palpation using shear wave elastography (SWE). For muscular diagnostic applications, characteristics of the shear wave profile will strongly depend on characteristics of the transducer as well as the orientation of muscular fibers and the tissue viscoelastic properties. The numerical s...
