Elastomeric composites for Arctic conditions: operation features and development experience

Elastomeric composites with tuned electromagnetic characteristics

This paper presents a novel elastomeric composite that exhibits a deformation-induced change in chirality. Previous efforts primarily dealt with a coil array in air without chiral tuning. Here, a composite is created that consists of an array of parallel, metallic helices of the same handedness embedded in a polymer matrix. The chiral response of the composite depends on pitch, coil diameter, w...

Preparation and Characterization of Shape Memory Elastomeric Composites

Shape memory polymers (SMPs) are a class of smart poly-meric materials that have the ability to " memorize " a permanent shape, be manipulated to retain or " fix " a temporary shape, and later recover to its original (permanent) shape upon a stimulus such as heat, electricity, or irradiation. 1-3 A large number of SMPs have been developed and utilized for actua-tors, deployable medical devices,...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Sealing of Rotary Drums for Operation Under Pressurized Conditions

Elastomeric nanoparticle composites covalently bound to Al2O3/GaAs surfaces.

This article reports the modification of Al2O3/GaAs surfaces with multifunctional soft materials. Siloxane elastomers were covalently bound to dopamine-modified Al2O3/GaAs semiconductor surfaces using MPt (M = Fe, Ni) nanoparticles. The sizes of the monodisperse FePt and NiPt nanoparticles were less than 5 nm. The surfaces of the nanoparticles as well as the Al2O3/GaAs substrates were modified ...
