Cascaded‐piezoelectric‐transducers (CPETs) is a key component in modern energy‐conversion fields, possessing versatile applications in ultrasonic scalpels, acoustic levitation, and sonar. However, serious self‐heating inevitably occurs inside high‐power CPETs, severely limiting their practical applications in broader fields. To tackle this, multidirectional heat‐escape channels of multidimensional...
In order to solve the uneven distribution of carbon nanotube (CNT)/reduced graphene oxide (RGO) composite and enhance its electrochemical energy storage performances, a CNT/RGO macroscopic body was prepared by partially oxidation stripping CNT via modified Hummers method. The CNT is partially stripped to prepare the composite of CNT and graphene oxide, and subsequently processed by l-ascorbic acid...
