摘要： Nanoparticle sized metal or alloy is synthesized through a reverse micelle system which includes the steps of a) forming a concentrated aqueous solution of transition metal salts with platinum salts b) dispersing the metal salt solution in a non aqueous solution of a surfactant c) adding a reducing agent to reduce the metal salts to metallic alloy nano-particles in the absence of oxygen d) separating the metallic alloy nanoparticles 1s) heating the metallic alloy nanoparticles under controlled time, atmosphere and temperature conditions sufficient to form particles of a desired size and magnetic characteristics . The, precipitated metal or alloy nanoparticle has an average size of 3nm and is superparamagnetic. Through controlled annealing treatment, the magnetic characteristics of the nanoparticles can be manipulated to achieve specific values in the final product that is suitable for predetermined applications. The nanoparticles exhibiting superparamagnetism are suitable for magnetic bio-bead applications. Weakly ferromagnetic magnetic alloy nanoparticles are suitable for actuator applications. The strongly ferromagnetic magnetic alloy nanoparticles exhibiting high coercivity can be potential candidate for magnetic data storage applications.

摘要： A passive memory device (2) includes a plurality of resonant members (3), e.g. of a cantilever or bridge-type form, that may have different resonant frequencies and that may be held against vibrations by end or side tethers (4). Data may be recorded in the device (2) by removing various of the tethers (4), so that, on applying an excitation signal, e.g. from a transmitter (5), untethered resonant members (3) vibrate strongly in response to their resonant frequencies, and provide a response signal that can be picked up e.g. by a receiver (6) and correlated with the excitation signal frequencies to determine which resonant members (3) have been untethered. The response by an untethered resonant member can correspond to a logical "1", whilst the lack of a response signal at a known resonant member frequency can correspond to a logical "0", or vice versa. The device may be made using MEMS technology, and various device structures and excitation/detection methods are disclosed including the use of excitation/detection circuitry within the device and the use of magnetic, Lorentz, electrostatic and/or piezoelectric forces.

摘要： A temperature-monitoring device for attachment to an item, e.g. a frozen food or health product, includes a trigger member (3) that is triggered by a set temperature condition to change state and so register exposure to the temperature condition. In one embodiment, the trigger member (3) is biased to disengage a Thermalloy element (11) once the Thermalloy's Curie temperature is exceeded and its magnetic force is weakened. The trigger member (3) moves sufficiently so that it will not re-engage the Thermalloy (11), even if temperatures recede. Exposure to a high temperature can thus be determined from the trigger member's state, e.g. by detecting an impedance change in an associated circuit, e.g. in an adjacent coil (9) through vibration of the trigger member (3) under an applied signal, or in a circuit (18) due to an open circuit at the trigger member (3) and Thermalloy (11). The device may be manufactured using MEMS technology. To allow storage above the Curie temperature, a tether (14) may initially hold the trigger member (3). The device may be activated, e.g. after freezing the item, by removing the tether (14), e.g. through laser ablation or a fusing current.
