Computational design of multifunctional materials
We propose a general scheme for the computational design of new materials using density functional theory. We then apply the scheme to two classes of materials; ferromagnetic ferroelectrics and half-metallic antiferromagnets. Our first ‘‘designer’’ ferromagnetic ferroelectric has subsequently been synthesized and the predicted properties verified. Our computations on halfmetallic antiferromagne...
متن کاملPreparation and characterization of multifunctional magnetic mesoporous calcium silicate materials
We have prepared multifunctional magnetic mesoporous Fe-CaSiO3 materials using triblock copolymer (P123) as a structure-directing agent. The effects of Fe substitution on the mesoporous structure, in vitro bioactivity, magnetic heating ability and drug delivery property of mesoporous CaSiO3 materials were investigated. Mesoporous Fe-CaSiO3 materials had similar mesoporous channels (5-6 nm) with...
متن کاملMultifunctional Upconversion-Magnetic Hybrid Nanostructured Materials: Synthesis and Bioapplications
The combination of nanotechnology and biology has developed into an emerging research area: nano-biotechnology. Upconversion nanoparticles (UCNPs) have attracted a great deal of attention in bioapplications due to their high chemical stability, low toxicity, and high signal-to-noise ratio. Magnetic nanoparticles (MNPs) are also well-established nanomaterials that offer controlled size, ability ...
متن کاملMultifunctional molecular carbon materials--from fullerenes to carbon nanotubes.
This critical review covers the timely topic of carbon nanostructures-fullerenes and carbon nanotubes-in combination with metalloporphyrins as integrative components for electron-donor-acceptor ensembles. These ensembles are typically probed in condensed media and at semi-transparent electrode surfaces. In particular, we will present a comprehensive survey of a variety of covalent (i.e., nanoco...
متن کاملThe Mechanics of Multifunctional Materials
Nano-structured NiTi instantaneously transforms from fcc austenite via an intermediate phase (the R-phase) into monoclinic B19’ martensite. At a grain size less than a critical limit of about 50nm no transformation can be observed even upon cooling down to cryogenic temperatures. In slightly larger grains the martensite appears as a laminate of alternating twinrelated Bain correspondence varian...
