    Abstract: Solid electrolyte and at least one of piezoelectric and thermoelectric materials are incorporated into material systems to provide them with self-healing and adaptive qualities. The piezoelectric and thermoelectric constituents convert the mechanical and thermal energy, respectively, concentrated in critical areas into electrical energy which, in turn, guides and drives electrolytic transport of mass within solid electrolyte towards and its electrodeposition at critical areas to render self-healing and adaptive effects. Material systems incorporating the solid electrolyte but not the piezoelectric and thermoelectric constituents are also amenable to healing and adaptive effects through external application of electric potential for electrolytic transport of mass towards and its electrodeposition at critical areas.

    Abstract: Pulp fibers derived from wood or non-wood plants or recycled paper products, which are about 0.1-30 mm long and about 0.001-0.1 mm in diameter with length-to-diameter ratio of about 30-3000, are dispersed in conventional concrete mixtures using conventional mixing equipment for effectively improving fresh and hardened concrete properties at relatively low cost. Dispersion is achieved by individualizing the plant pulp fibers so that they are not fully bonded to each other, and dispersing the individual fibers in concrete at relatively low dosages of about 0.3-30 kg per cubic meter. Once individualized, the affinity of plant pulp fibers for water facilitates their dispersion in conventional concrete mixtures. Fresh concrete mixtures incorporating the dispersed individualized plant pulp fibers possess desirable workability, resistance to segregation and bleeding, pumpability, finishability, and reduced rebound when pneumatically applied. Hardened concrete materials incorporating the dispersed individualized plant pulp fibers provide improved crack resistance, toughness characteristics, impact resistance, fatigue life, abrasion resistance, and other mechanical, physical and durability characteristics. Precast and cast-in-pace concrete as well as plain and reinforced concrete and shotcrete benefit from such improvements in fresh and hardened material properties rendered by dispersed plant pulp fibers.

    Abstract: Method of joining articles using microscale brazing alloy particles reinforced with slender nanomaterials is described. Surface modified graphite nanomaterials were dispersed in a medium comprised of metal alloy particles, this dispersion was introduced at the interface between the joining articles followed by heating under ultra high vacuum. The nanomaterial-to-metal alloy surface contacts were enhanced by at least one of fusion, embedment and chemical reaction phenomena under high temperature and ultra high vacuum yielding true nanocomposite at the interface. The fusion, embedment and chemical reaction phenomena enhance at least one of the mechanical, electrical, thermal, durability and functional attributes of these contact points, which translate into improved properties of the joined article. The enhanced contact points enable effective use of the distinct qualities of nanomaterials towards development of joints which offer unique balances of strength, ductility, toughness, energy absorption, thermal stability, weathering resistance and other characteristics.

    Abstract: The present invented mechanism comprises more than two (legs) with phase difference (like polygon-shape, ellipse-shape, and etc) between their rotation angles to produce pre-loading for improved adhesion. Two rigid plates covered with adhesives are attached to each phase difference wheel. Each plate connects to the wheels via a hinge embodying a torsional spring, which forces the plate back to its original position after each contact with surface. The phase difference wheels are made of elastic materials for application of controlled pre-loads at contact surfaces during locomotion. The difference between height and width of each wheel as well as the elastic properties of the materials determine the pre-load pressure applied during locomotion. The pre-load pressure is not strongly dependent on the orientation of locomotion. This enables locomotion in vertical, inclined and even upside-down orientation and also in the non-gravity environment.

    Abstract: Pseudoelastic elements are shaped in order to form springs which exhibit relatively constant force levels over a major fraction of maximum deflection capacity during loading and also during unloading. The shape of sail pseudoelastic elements is chosen to concentrate at least one of flexural and torsional deformations within limited regions. The element may be braced outside said regions in order to further concentrate deformations within said regions. Loading of said pseudoelastic springs thus produces strains within said regions which are largely corresponding to the upper pseudoelastic stress plateau where strain variations cause relatively small changes in stress. Unloading of said pseudoelastic springs also produces strains within said regions which are largely corresponding to the lower stress plateau of the pseudoelastic stress-strain curve where stress is subject to relatively small changes with strain variations. Said psueodoelastic springs can be used in brush holders which can benefit from a relatively constant level of force as deflections occur due to brush wear.

    Abstract: A thermoplastic polymer of relatively low melt temperature is blended with at least one of thermosets, elastomers, and thermoplastics of relatively high melt temperature in order to produce a polymer blend which absorbs relatively high quantities of latent heat without melting or major loss of physical and mechanical characteristics as temperature is raised above the melting temperature of the low-melt-temperature thermoplastic. The polymer blend can be modified by the addition of at least one of fillers, fibers, fire retardants, compatibilisers, colorants, and processing aids. The polymer blend may be used in applications where advantage can be taken of the absorption of excess heat by a component which remains solid and retains major fractions of its physical and mechanical characteristics while absorbing relatively high quantities of latent heat.
