Switch Solvent, Change Color
Researchers in South Korea have developed a carbon nanostructure capable of changing shape and color depending on the solvents used.
Transforming Rusty Steel Into Batteries
Scientists have successfully converted rusty stainless steel mesh into stable, low-cost electrodes for potassium-ion batteries.
Bend It Like Bamboo
The fibers in bamboo are distributed to maximize flexural rigidity with the smallest volume of wood material possible.
Gold That Goes Invisible When Ground
This gold compound shifts its emission profile by an unprecedented 452 nm when ground, changing from fluorescent blue to infrared.
Feather-Light Cathodes Unlock The Potential Of Lithium-Oxygen Batteries
It may be made entirely out of metal, but this cathode is still ultra-light.
Whisker Crystals Enable Cooling Without Coolants
One-dimensional crystals with very high thermoelectric efficiency could make ultra-low temperature cooling more practical.
Using Holographs To Move & Bend Cells At Will
Researchers in South Korea have used laser holography to control the movement of irregularly shaped microscopic objects including red blood cells.
Light-Sensitive Shape-Shifting Material Created
Researchers have created self-assembling molecules which can be broken down by ultraviolet light to recombine into novel and exotic shapes.
Gecko-Inspired Adhesive Sticks And Releases On Command
Scientists have developed a method to integrate nanostructured hydrogel fibers on an inorganic membrane to mimick the gecko's sticking and detaching mechanism.
