This work attempts to explore the dynamic and steady-state rheological properties of chitosan modified clay (CMCs) at highly hydrated state. CMCs with different initial chitosan/clay weight ratios (s) were prepared from pre-exfoliated clay via electrostatic adsorption process. Thermogravimetric analysis and optical microscopy were used to determine the adsorbed content of chitosan (m) in CMCs a...

Sebacic acid-based thixotropic supramolecular Ni( ii )/Zn( )-metallogels are utilized for inhibiting poisonous bacteria and offering light-responsive semiconducting diodes with non-ohmic conduction mechanism.

The aim of the work is a description of the rheological behaviour of thickened sewage sludge. The sample of thickened sludge was collected from the wastewater treatment plant, where pressure flotation unit is used for a process of thickening. The value of dry matter of collected sample was 3.52%. Subsequently the sample was diluted and the rheological properties of individual samples were obtai...

Direct ink writing (DIW) requires careful selection of composition with specific rheological properties, and it has limitations, such as the inability to create overhanging parts or branched geometries. This study presents an investigation into enhancing 3D printing process through use a heterophase system, aiming overcome these limitations. A modification was carried out in printer constructio...

In the present work, dynamics of a single spherical gas bubble surrounded by rheopectic fluid obeying Quemada model is numerically investigated while undergoes oscillatory motion due to acoustic forcing. The generalized form Rayleigh–Plesset equation has been used for studying in fluids. integro-differential representing solved using finite-element method (FEM) and also Gauss–Laguerre quadratur...

Thixotropic structural build-up is an intrinsic property of fresh cementitious materials, playing a significant role in pumpability, stability and formwork filling concrete, as well buildability 3D printing. This paper presents critical review on the thixotropic cement-based materials from viewpoints origins, evaluation methods, influencing factors applications. Recent research indicates that o...
