TL;DR: In this paper, a causal relationship between the hydrogen-bonding ability of the liquid and the colloidal microstructure observed was investigated in a range of polar organic media and it was shown that the silica forms stable low-viscosity sols exhibiting shear thickening behavior in a host of liquids, including ethylene glycol and its oligomers and short-chain alcohols, such as n-propanol.

TL;DR: The combination of shear- and strain-thickening behavior can be qualitatively explained using a clustering mechanism, which attributes the various phenomena to the formation of temporary, flow-induced clusters.

TL;DR: In this article, the theory and role of interfacial rheological properties experimental results on foam rheology experimental techniques for the characterization of foams fundamental methods for measuring foam stability nonaqueous foams additives for foams foam wet processing in the textile industry foams in personal care products, enhanced oil recovery foams for firefighting foams, mineral flotation and separation processes science and technology of silicone antifoams.

TL;DR: In this paper, the authors compare different methods of measuring yield stress: conventional extrapolation of shear stress in steady shear experiments and dynamic experiments at large strain amplitudes, denoted by the maximum in the elastic stress, the product of the elastic modulus and strain, when plotted as a function of strain amplitude.

TL;DR: In this paper, the authors reported preparation of nanofibers containing alginate using two different molecular weights (MWs): 37 kDa and 196 kDa), and compared the solution properties, including entanglement concentration, relaxation time, conductivity, and surface tension, to their ability to be electrospun.
