Due to their non-toxic nature, biodegradability and production from renewable resources, research has shown an increasing interest in the use of biosurfactants in a wide variety of applications. This paper reviews the characterization of rhamnolipid and sophorolipid biosurfactants based on their hydrophilicity/hydrophobicity and their ability to form microemulsions with a range of oils without ...

In this study, multiwall carbon nanotubes (MWCNTs) and double-wall (DWCNTs) have been dispersed in polylactide (PLA) polyamide 11 (PA11) using an internal mixer. Rheological characterization confirmed the formation of nanotube (CNT) networks PLA PA11 attributed to well-dispersed CNTs respective matrices. A lower rheological percolation threshold PLA/MWCNT nanocomposites (less than 0.5 wt. %) co...

Magneto-rheological fluids (MRF) are suspensions of particles which can be magnetized. MRF exhibit fast, strong and reversible changes in their rheological properties when a magnetic field is applied. A commercially available damping system that takes full advantage of the controllable technology of MRF and delivers valveless damping control appeared on passenger vehicles in 2003. Further comme...

Applications of nanowires into future generation nanodevices require a complete understanding of the mechanical properties of the nanowires. A great research effort has been made in the past two decades to understand the deformation physics and mechanical behaviors of nanowires, and to interpret the discrepancies between experimental measurements and theoretical predictions. This review focused...

A comprehensive rheological characterization of highly concentrated suspensions or pastes is mandatory for a targeted product development meeting the manifold requirements during processing and application of such complex fluids. In this investigation, measuring protocols for a conclusive assessment of different process relevant rheological parameters have been evaluated. This includes the dete...
