TL;DR: In this paper, the authors examined the preparation and characterisation of hexane-in-water emulsions stabilised by clay particles, and concluded that the most stable emulsion can be prepared using a bentonite concentration of 2% (or more); an o/w ratio greater than 0.05% (w/v).

TL;DR: In this paper, the authors present an attempt to explain in a simple way, understandable to a broad spectrum of readers, the unusual combination of the mechanical properties of the recently developed new class of superhard nanocomposites, such as high hardness which significantly exceeds that of the rule of mixtures, enhancement of the elastic modulus as measured by the indentation technique, very high elastic recovery which is observed upon the indentations and the absence of crack formation even under elastic deformation corresponding to a strain of more than 10%.

Future experimental work is suggested which should bring further progress towards the understanding of these materials.

TL;DR: In this paper, the authors show that the bulk modulus of viscoelastic materials exhibits a singularity at ν = 1/2 and that the changes in the modulus are negligible as ν approaches 1 2.

TL;DR: In this paper, the most general objective stored elastic energy for a second gradient material is deduced using a literature result of Fortune ´ & Vallee, proving that these materials are characterized by seven elastic moduli and generalizing previous studies by Toupin, Mindlin and Sokolowski.
Abstract: In the spirit of Germain the most general objective stored elastic energy for a second gradient material is deduced using a literature result of Fortune ´ & Vallee. Linear isotropic constitutive relations for stress and hyperstress in terms of strain and strain- gradient are then obtained proving that these materials are characterized by seven elastic moduli and generalizing previous studies by Toupin, Mindlin and Sokolowski. Using a suitable decomposition of the strain-gradient, it is found a necessary and sufficient condition, to be verified by the elastic moduli, assuring positive definiteness of the stored elastic energy. The problem of warping in linear torsion of a prismatic second gradient cylinder is formulated, thus obtaining a possible measurement procedure for one of the second gradient elastic moduli.

TL;DR: In this paper, the elastic moduli of hexagonal beryllium oxide, zinc sulfide, and cadmium selenide at 25°C were determined by measuring ultrasonic wave velocities in the 20 to 50 MHz frequency range.
Abstract: The elastic moduli of hexagonal beryllium oxide, zinc sulfide, and cadmium selenide at 25°C have been determined by measuring ultrasonic wave velocities in the 20‐ to 50‐MHz frequency range. The data are compared with other literature data and discrepancies are discussed. The adiabatic bulk modulus, volume compressibility, and Debye temperatures are also computed.
