f-element materials ∙ electronic-structure-driven synthesis ∙ anisotropic magnetic interactions ∙ spintronics
Magnetic anisotropy (the propensity for magnetization to align in a particular direction) is created by restricting the motion of electrons within a material.
The highly tunable electronic structure of the f-elements holds the promise of magnetic building units that allow predictive bottom-up design of powerful new magnetic materials.
tunneling magnetoresistance ∙ sensing devices ∙ magnetotransport ∙ nanoparticle solids ∙ colloidal nanoparticles
The precision control offered by magnetoresistive devices continues to be a driving force in electronic sensing technologies. Merging nanosynthesis with classic mechanisms allows us to rapidly explore sensitive, tunable magnetoresistance in monolithic, simply-prepared materials.
exchange bias ∙ exchange-spring magnetism ∙ bottom-up molecular design ∙ heterostructured materials
The nature of a magnetic material can be completely transformed by interactions with other materials on the sub-micron scale. Fundamental control of these powerful synergistic forces to construct new materials can proceed intuitively if single-domain magnets are used as the basic building units.
ultrasound contrast agents ∙ medical imaging ∙ polymer nanoparticles ∙ fluorophilic interactions
The interaction between vibrational energy (sound and ultrasound) and matter is well-understood and widely utilized in nature (echolocation), navigation (sonar), engineering (non-destructive testing), and medical diagnostics. By designing materials optimized to interact with sound in new ways, information-rich signals can be created, giving information about their location, enviroment, and motion.
biopolymers ∙ nature-inspired functional materials ∙ metal chelation ∙ amorphous materials characterization
Many biomaterials accumulate metals naturally or from environment pollution, yet the implications often remain opaque due to the complex amorphous structure of the material. Development of models based on magnetometry offers unique insight into coordination, redox state, electronic interactions, and reactivity of these vitally important materials.
