A Graphene Quantum Dot Film with a Nanoengineered Crack-Like Surface via Bubble-Induced Self-Assembly for High-Power Thermal Energy Management Applications

Ben Chu et al.

Summary: Films with nanoengineered crack-like surfaces were generated using a bubble-induced self-assembly method and self-dispersible graphene quantum dot (GQD) nanofluid. The crack-like micro/nanostructure not only improved capillary wicking performance but also enhanced heat transfer performance. Furthermore, the GQD film showed high stability and improved concentration ratio and electrical efficiency in concentrated photovoltaics for high-power thermal energy management applications.

Opto-Thermocapillary Nanomotors on Solid Substrates

Jingang Li et al.

Summary: Motors that can convert different forms of energy into mechanical work play a crucial role in the development of human societies. The miniaturization of motors to the nanoscale is challenging due to the strong Brownian motion in liquid environments. In this study, we develop light-driven optothermocapillary nanomotors that can operate on solid substrates, effectively suppressing the interference of Brownian motion. Our nanomotors demonstrate robust orbital rotation and have the capability to power functional devices at the nanoscale.

Site-Selective Bipolar Electrodeposition of Gold Clusters on Graphene Oxide Microsheets at a 3D Air|Liquid Interface

Pacharapon Kankla et al.

Summary: An innovative wireless approach is proposed for asymmetric site-selective deposition of gold clusters on graphene oxide microsheets by performing bipolar electrochemistry at the 3D air|liquid interface present in an assembly of bubbles constituting a foam. The exfoliated graphene oxide (EGO) microsheets are introduced into a bipolar electrochemical cell filled with foam composed of a nonionic surfactant, water, and a gold metal precursor, enabling successful site selective modification with gold clusters.
