They demonstrate a 300-fold increase in coupling strength compared to that of bulk strontium ruthenate by reducing its electronic dimensionality Many interesting functional properties of materials with advanced applications often rely on the electron–phonon coupling strength. However, the coupling strength is believed to be an intrinsic material property, which limits…

Researchers introduce hydrotropic-supporting electrolyte to enhance the solubility of organic redox molecules for electrochemical capacitors Redox-enhanced electrochemical capacitors (ECs) are a sustainable alternative to the dominant battery technologies that use metal ions and corrosive chemicals. However, obtaining organic redox-active electrolytes with sufficient solubility for use in redox-enhanced ECs is challenging…

The new graphene-based conductive hydrogel electrodes offer convenience of use, controllable degradation, and excellent signal transmission Implantable bioelectrodes have great potential for efficient biological signal transmission. However, use of conventional metal-based bioelectrodes is associated with painful incision, tissue inflammation, inefficient signal transduction, and uncontrolled stability in living biological systems. To…

Scientists devise a position-controlled doping strategy to improve the thermoelectric performance of indacenodithiophene-based polymer High charge carrier mobility and low thermal conductivity of indacenodithiophene (IDT)-based polymers make them ideal candidates for thermoelectric materials. However, they suffer from low electric conductivity, a prerequisite for high thermoelectric performance. …
