By changing the direction of a magnetic field, so-called magneto-tactic bacteria are able to make a full U-turn. They can be taught line dancing in this way, inside the tiny micro channels of a lab on a chip.
Researchers have found a solution using visible light to reduce waste produced in chemically activated molecular switches, opening the way for industrial applications of nanotechnology ranging from anti-cancer drug delivery to LCD displays and molecular motors.
In the fight against global warming, carbon capture is gaining momentum, but standard methods are plagued by toxicity, corrosiveness and inefficiency. Using a bag of chemistry tricks, materials scientists have invented low-toxicity, highly effective carbon-trapping 'sponges' that could lead to increased use of the technology.
Researchers have discovered that if lead atoms are intercalated on a graphene sheet, a powerful magnetic field is generated by the interaction of the electrons' spin with their orbital movement. This property could have implications in spintronics.
Traditional genomic, proteomic and other screening methods currently used to characterize drug mechanisms are time-consuming and require special equipment, but now researchers offer a multi-channel sensor method using gold nanoparticles that can accurately profile various anti-cancer drugs and their mechanisms in minutes.
In new work, researchers find Ga ion vacancy is the critical factor that causes the high off-state current, low on/off ratio of GaTe FET and large hysteresis at room temperature through electrical transport measurements at variable temperatures and first-principles calculations as well.
Recent research efforts have led to a new technique to magnetically deliver drug-carrying particles to hard-to-reach targets. The method has the potential to transform the way deep-tissue tumors and other diseases are treated.
A new method that creates large-area patterns of three-dimensional nanoshapes from metal sheets represents a potential manufacturing system to inexpensively mass produce innovations such as plasmonic metamaterials for advanced technologies.
If seeing is believing, C.K. Choi has a passion for clarity - in a very tiny world. The assistant professor of mechanical engineering's research lies at the micro-scale, in channels no thicker than a strand of hair.
