Abstract An excellent combination of either oxides or metallic nanoparticles (NPs) and functional π‐electron rich conjugated molecules can originate a variety intriguing phenomena convenient for technological applications. Functional π‐conjugated aromatic hold the potential to control size, shape, morphology, optoelectronic properties through formation covalent interfaces. Interfacial charge transfer at nanoparticles−molecules interfaces plays vital roles in modulating photophysical...
Laser-induced graphene (LIG) on paper substrates is a desirable material for single-use point-of-care sensing with its high-quality electrical properties, low fabrication cost, and ease of disposal. While prior study has shown how the repeated lasing enables synthesis porous graphitic films, however, process-property correlation process surface microstructure electrochemical behavior, including charge-transfer kinetics, missing. The current presents systematic in-depth LIG to elucidate...
Abstract Flexible micro‐supercapacitors, with high energy and power density, using materials a low environmental impact are attractive for next‐generation storage devices. Carbon‐based widely used supercapacitors but can be increased in density via combination metal oxides. Red mud is an iron‐oxide‐rich by‐product of aluminum production, which needs to more utilized reduce its damage. To achieve flexible micro‐supercapacitor device laser‐induced graphene (LIG) supercapacitor realized from...
