Hydroxyapatite whiskers provide improved mechanical properties in reinforced polymer composites.
Synthetic hydroxyapatite (HA) whiskers have been utilized as a new, biocompatible reinforcement for orthopedic biomaterials. High-density polyethylene (HDPE) was reinforced with either the synthesized HA whiskers or a commercially available spherical HA powder using a novel powder processing technique that facilitated uniform dispersion of the reinforcements in the matrix prior to compression m...
متن کاملProperties of Doped GaSb Whiskers at Low Temperatures
Temperature dependencies of GaSb whiskers' resistance doped with Te to concentration of 1.7 × 1018 cm-3 were measured in temperature range 1.5-300 K. At 4.2 K temperature, a sharp drop in the whisker resistance was found. The observed effect is likely connected with the contribution of two processes such as the electron localization in the whiskers and transition in superconducting state at tem...
متن کاملThermoelectric properties of Bi2Sr2Co2O9 whiskers under hydrostatic pressure
We report the temperature dependence of thermopower (S) in the ab plane of Bi2Sr2Co2O9 ~BC-222! single crystalline whiskers under high pressure up to 1.2 GPa. Special modifications were made to our high-pressure transport measurement system to improve the measurement accuracy of S for whiskers with high resistance. Pressure improved the contact resistance dramatically. We observed a slight decr...
متن کاملActuation and Sensing properties of Electroactive Polymer Whiskers
In a world of unknown, touch modality is a key avenue for environments exploration. Implementation of such modality in mobile robot has been a major challenge for many research teams. Recently, several artificial whisker systems have been studied as promising tactile sensor. One key to the whisker’s functionality is its sensor system. Our laboratory recently synthesized new electroactive polyme...
متن کاملTin Whiskers Remain A Concern
The elimination of lead in electronic equipment due to governmental regulations (European Union End of Life Vehicle Directive and European Union Restriction of Hazardous Substances Directive) has increased the risk of electrical shorting due to the formation of tin whiskers in electronic products. Tin whiskers are hair-like tin structures that grow sporadically on surfaces coated with tin. Whis...
