A modified Nafion dispersion for direct screen printing was developed and characterized. Commercial solution neutralized to its sodium form the solvent replaced by a screen-printing-compatible solvent. The has optimized rheological properties including shear-thinning behavior, thixotropy, moderate yield stress. elemental composition chemical states of were characterized X-ray photoelectron spec...

KEY POINTS The passive stiffness of the calf muscles contributes to standing balance, although the properties of muscle tissue are highly labile. We investigated the effect of sway history upon intrinsic ankle stiffness and demonstrated reductions in stiffness of up to 43% during conditions of increased baseline sway. This sway dependence was most apparent when using low amplitude stiffness-mea...

Compared with conventional two-part alkali-activated materials (AAMs), one-part AAMs have several advantages, especially the simple production using only water similar to ordinary Portland cement. However, are much less researched, in terms of rheology. Understanding rheological behavior such binders is a crucial step for their production, placement, and application construction industry. This ...

Tungsten trioxide (WO3) is used to prepare the important electrochromic layer of device as a wide bandgap semiconductor material. In this study, WO3 film was successfully prepared by screen printing. To modify thixotropy and wettability ink, polyvinyl alcohol (PVA) 2-perfluoroalkyl ethanol (FSO) were added in ammonium meta-tungstate (AMT) solution. We found that PVA additive could improve dynam...

Lamellar gel networks based on mixtures of cetostearyl alcohol and a cationic surfactant, cetyl-trimethylammonium chloride, were studied using combination rheometry optical coherence tomography (OCT) velocimetry. Experiments conducted in stress-controlled rheometer with parallel plate geometry. Each formulation was found to exhibit yield stress thixotropy. The shear start-up behavior response c...
