The left inset is a photograph of bismuth telluride (Bi2Te3)-based thermoelectric (TE)... view more  Credit: Korea Institute of Science and Technology(KIST) A thermoelectric device is an energy conversion device that utilizes the voltage generated by the temperature difference between both ends of a material; it is capable of converting heat energy, such as waste heat from industrial sites, into electricity that can be used in daily l...

 E-Mail IMAGE: Schematic diagram of a nickel-based 3D nanohelix electrocatalyst system doped with oxophilic transition metal atoms. Incorporation of oxophilic transition metals into the nickel-based nanohelixes with abundant surface active sites optimizes the... view more  Credit: POSTECH To resolve the energy crisis and environmental issues, research to move away from fossil fuels and convert to eco-friendly and sustainable hydrogen energy is well underway around the world. Recently, a team of researchers at POSTECH has proposed a way to efficiently produce hydrogen fuel via water-...

 E-Mail IMAGE: Optical microscope (OM) and scanning electron microscope (SEM) images of viscous liquid metal particles during stretching. During this process, the oxide film on the surface of the microparticles may stretch... view more  Credit: POSTECH Today's electronic devices strive for new form factors - to make them foldable, stretchable, and deformable. To produce such devices that are highly stretchable or deformable, it is necessary to develop electrodes and circuit lines whose electrical properties can withstand harsh deformation or mechanical damage. To this, POSTECH-Yonse...
