The research of Dai group interfaces with chemistry, physics, materials science and biophysics. They are interested in solid state and soft condensed materials that have well-defined atomic structures. Ongoing projects include developing new synthetic routes to ordered nanomaterial architectures; electrical, mechanical, electromechanical and electrochemical characterizations at the nanoscale; and probing the real-space structures and functions of biological molecules. Their work are in the areas of material chemistry, inorganic synthesis, solid state physics, electron transport and scanning probe microscopy. A specific research program involves the development of new synthesis methods to obtain ordered carbon nanotube architectures on surfaces. These novel nanowire architectures are ideal model systems for addressing fundamental physics problems in low dimensions, and for future device applications. Their overall approach involves the combination of
inorganic synthesis of mesoporous catalytic materials and chemical vapor deposition with microfabrication techniques. With the synthesized nanowire architectures, they are carrying out electrical and electromechanical measurements of individual nanotube molecular wires, aimed to understand the properties of quasi-one-dimensional solids, elucidating quantum mechanical effects in small systems, and explore their applications in future miniaturized devices.
Another project involves using scanning probe microscopy techniques to probe the structural properties of biological macromolecules, and elucidate the interactions between individual molecular pairs.
