To improve the manufacturing efficiency of ceramic MOX fuels, wet processes, such as extrusion, are studied a novel production method. The flowing behavior, is essential to obtain smooth and defectless rods. This work provides study on rheological properties paste assesses possibility produce nuclear fuel by extrusion. Surrogate powders UO2 PuO2 were used, respectively TiO2 Y2O3. A with 40.9%vo...

Under specific conditions, rod-like cellulose nanocrystals (CNC) can assemble into structurally ordered soft glasses (SGs) with anisotropy that be controlled by applying shear. However, to achieve full structural control of SGs in real industrial processes, their response mixed shear and extensional kinematics needs determined. We hypothesise knowing the rheology CNC-based glass adopting a suit...

The mechanical properties of liver can sensitively indicate the progression of hepatic fibrosis. Mechanical tissue characterization involves the analysis of the complex shear modulus measured either by oscillatory rheometry or by in vivo elastography. In this study, bovine liver specimens were investigated by oscillatory rheometry and multifrequency magnetic resonance elastography (MRE) in a co...

In this study, the compatibility of the blends of polypropylene (PP) and polybutene-1(PB-1) homopolymer before and after long chain branching process were studied. The blends were prepared and long-chain branched directly via reactive extrusion process in presence of free radical initiator and trimethylolpropane tri methacrylate (TMPTMA) poly functional monomer. The optimum percentage of TMPTMA...

Economic processing of lignocellulosic biomass requires handling the biomass at high solids concentration. This creates challenges because concentrated biomass behaves as a Bingham-like material with large yield stresses. Here we employ torque rheometry to measure the rheological properties of concentrated lignocellulosic biomass (corn stover). Yield stresses obtained using torque rheometry agr...

The development and growth of microfluidics has stimulated interest in the behaviour of complex liquids in microscale geometries and provided a rich platform for rheometric investigations of non-Newtonian phenomena at small scales. Microfluidic techniques present the rheologist with new opportunities for material property measurement and this review discusses the use of microfluidic devices to ...
