This work aimed to analyze the possibility and performance of the temperature controlled hyperthermia based on AC heating of magnetic nanoparticles with low Curie temperature. Temperature dependence of dynamic magnetic susceptibility has been studied experimentally on fine powders of La(0.8)Ag(0.15)MnO(2.95) in the frequency range of 0.5-2.0 MHz. Critical(More)
The purpose of this study was to introduce newly synthesized nanomaterials as an alternative to superparamagnetic ironoxide based particles (SPIO) and thus to launch a new platform for highly controllable hyperthermia cancer therapy and imaging. The new material that forms the basis for this article is lanthanum manganite particles with silver ions inserted(More)
In this paper, we have analyzed mechanical resonances in carbon nanotubes (CNTs) based on single, vertically-oriented tubes for their potential application in high-frequency, high-Q, miniaturized resonators. The nano-electro-mechanical (NEM) resonators were modeled using a commercially available finite-element-simulator, where the electro-mechanical(More)
We report the observation of an unusual phase assembly behavior during the growth of hexagonal LuFeO(3) thin films which resulted in the formation of epitaxial Fe(3)O(4) nanolayers. The magnetite layers were up to 5 nm thick and grew under the conditions at which Fe(2)O(3) is thermodynamically stable. These Fe(3)O(4) nanolayers act as buffer layers(More)
A survey questionnaire concerning the procedures used to distribute controlled substances was mailed to 100 randomly selected Massachusetts hospital pharmacies. The tabulated results were compared to a similar study surveying 285 short-term medical and surgical hospitals nationwide. Of the 58 responding hospitals, 47 (81%) reported controlling either all or(More)
