Special Issue Information

Dear Colleagues,

Microsystems are miniaturized devices which perform specific or combined functions for computation and information processing; sensing and actuation; testing and measurement; molecule and material processing. This special issue aims to showcase research papers, short communications, and review articles that focus on recent progress in synthesis, assembly and testing of nanomaterials using microsystems and the functional applications of nanomaterials in microsystems. The topics of interest include, but are not limited to:

The use of microfluidics to synthesize, assemble, purify and deliver nanomaterials, functional nanostructures, and nanostructured thin films.

The use of micromachines to manipulate, assemble, separate and fabricate nanomaterials, nanostructures, and nanostructured thin films.

The use of microsystems for nanomaterial characterizations e.g. MEMS-based mechanical testing.

Microsystems with integrated nanomaterials such as catalytic microreactors; electrochemical biosensors; neural prosthetics; gas micro-sensors; smart sensors/actuators for biomedical applications; and micro batteries.

Capillarity refers to the driving force to propel liquid through small gaps in the absence of external forces, and hence enhanced capillary force has been pursued for various applications. In this study, flower like ZnO nanostructures are successfully deposited to enhance capillarity of microwick structures that are specially designed to augment boiling heat transfer performance. Microreactor-assisted nanomaterial deposition, MANDTM, is employed with a flow cell to deposit the ZnO nanostructures on a large sized microwick (4.3 cm × 10.7 cm) with dual-channel configuration. A capillary rise experiment based on the mass gain method is first performed using water and ethanol (EtOH) as the working liquids to demonstrate the enhanced capillary force induced by the ZnO nanostructure on the microwick structure. It is found that the coating of ZnO nanostructure effectively propels the working fluids through the nano- or micro pores created from the ZnO nanostructure and consequently improves the capillary force. In order to investigate the wicking mechanism of the ZnO coated microwick structure, the capillary rise result based on height measurement was compared with analytical models. It is found that the gravity effect and viscous force play an important role in wicking rise of the coated wick structure. This study aims at demonstrating the capability of the integrated MAND process with a flow cell for producing a large scaled nanostructured surface, which eventually has a great potential for enhanced boiling heat transfer.
