Janus-faced viscoelastic gelling agents—possessing both elastic and viscous characteristics—provide materials with unique features including strengthening ability under stress a liquid-like character lower viscosities relaxed conditions. The mentioned multifunctional is manifested in several body fluids such as human tears, synovial liquids, skin tissues mucins, endowing the special physical re...

single-walled carbon nanotubes (swnts) are among the promising nano-devices for delivery of therapeutic agents. yet the drastic hydrophobic natures of swnts make their handling and hence application difficult.several researches have been conducted to make them more hydrophilic and water dispersible and less toxic. among the different approaches, dispersion methods exploit different reagents suc...

INTRODUCTION The discovery of the conductive properties of conjugated organic polymers in the late 1970s initiated intense investigations of their synthesis, chemistry and physical properties. Today, they are widely studied for various applications, e.g. optoelectronics in displays or organic solar cells. Beyond general academic curiosity towards the generation and properties of unusual nanostr...

We review the viscous and viscoelastic behaviours of concentrated food emulsions and plant food suspensions. Special attention has been given to the influence that food processing exerts on the rheological characteristics of the abovementioned foodstuffs.
