During the past 30 years, more and 3D-printing techniques based on suspensions with specific rheological properties have been innovated improved. In this review, principles of dispersing controlling powders for suspension-based 3D printing are summarized. The direct ink writing (DIW) taken as an example printing. According to property requirement writing, routes how its can be manipulated summa...

The paper reviews recent experimental results concerning a wide variety of magnetic nanofluids with high saturation magnetization. Magnetic, rheological and magneto-rheological properties are presented and discussed, especially related to nanostructural processes and colloidal stability in applied magnetic field.

The biogas process has long been a part of our biotechnical solutions for the handling of sewage sludge and waste. However, in many cases the existing process applications need to be optimized to improve the extent of biogas production as a part of the energy supply in a sustainable and viable society. Although the principles are well known, process disturbances and poor substrate utilization i...

Using rheological shear and oscillation measurements, it is possible to determine the viscoelastic properties of a system quantitatively, as a function of the many influential parameters. The aim here was to establish structure-property relationships for a polymer in a solvent system from the viscoelastic material functions correlated with data from polymer analysis These structure-property rel...

In this work, a stable NiFe2O4 paraffin based ferrofluid was prepared via high energy milling. The rheological properties of ferrofluid were studied. Bingham plastic, HerschelBulkley and Casson models were used to evaluate the shear stress-shear rate dependency. The ferrofluid exhibited a shear thinning behaviour for all studied magnetic field. The magneto-viscous effect and thixotropy of...

A series of Graphene Oxide/ Polyacrylamide (GO/PAM) super-elastic nanocomposites with different amounts of Graphene Oxide Nanosheets (GONSs) (0.5, 1, 1.5, and 2 wt. %) were synthesized using an in-situ polymerization in an aqueous medium in this paper. To this end, we proposed a method for obtaining super-elastic nanocomposites with a high dispersion of GONSs in the PAM chains as well as in a r...

There are many kinds of deformable objects in our living life. Some of them demonstrate rheological behaviors, such as human tissues, food, and clay. Comparing with elastic or viscoelastic objects, rheological objects have not been studied intensively. Especially, effective methods for parameter identification have not been established until now. In this paper, we summarize two FE dynamic model...

Rheological object, such as various food products and biological tissues, has both elastic and plastic properties. Modeling of rheological object has not been studied frequently comparing with the modeling of elastic one. Our previously developed FE models of rheological objects were based on triangular or tetrahedra finite elements. In this paper, the FE model of rheological object formulated ...

The objective of this study was to investigate the effect of selected biopolymers on the rheological properties of surimi. In our paper, we highlight the functional properties and rheological aspects of some starch mixtures used in surimi. However, the influence of some other ingredients, such as cryoprotectants, mannans, and hydroxylpropylmethylcellulose (HPMC), on the rheological properties o...

As the search of hydrocarbon has moved to more remote and unconventional areas, including low temperature offshore Arctic circle, new challenges have also emerged life industry. The biggest drilling fluid-related challenge in environments, is maintaining fluid properties under an extreme difference between bottom hole surface. rapid change conditions can affect mud rheological reduce performanc...
