Special Issue Information

Dear Colleagues,

Emerging function nanomaterials owning tunable properties offer a wide range of opportunities for the challenging development and improvement of microsystems and devices in various research areas, e.g., microfluidic systems, microsensors, batteries, supercapacitors, fuel cells, hydrogen production, carbon dioxide reduction, solar energy conversion, et al. However, there are still bottleneck challenges in tuning the functional properties, e.g., structures, band diagrams, surface, interface, stability, and compatibility, of materials in nanoscience and nanotechnology. Here, this Special Issue of journal Molecules aims to reflect the tremendous world-wide attempts and achievements of emerging functional nanomaterials, including carbon-based materials, III-nitrides nanowires, transition metals, 2D materials, perovskite, porous materials, nano clusters, and so on, with their applications in various microsystems and devices. This special topic will present the recent attempts and demonstrations of nanomaterials fabrication technology, tunable structures and properties, and their applications, which may provide enormous information for the researchers working on nanomaterials-based applications.

We welcome the original research papers in the format of reviews, articles, and communications, with the topics including, but not limited to:

Functional nanomaterials for microsystems;
Functional nanomaterials for energy storage devices;
Functional nanomaterials for energy conversion devices;
Functional nanomaterials for new energy;
Functional nanomaterials for microfluidic devices;
Functional nanomaterials for micro/nano sensors
Functional nanomaterials for micro/nano robotics

Abstract

Conductive LaNiO₃ (LNO) films with an ABO₃ perovskite structure deposited on silicon wafers are a promising material for various electronics applications. The creation of a well-defined columnar grain structure in CSD (Chemical Solution Deposition) LNO films is challenging to achieve on an amorphous substrate. Here, we report the formation of columnar grain structure in LNO films deposited on the Si-SiO₂ substrate via layer-by-layer deposition with the control of soft-baking temperature and high temperature annealing time of each deposited layer. The columnar structure is controlled not by typical heterogeneous nucleation on the film/substrate interface, but by the crystallites’ coalescence during the successive layers’ deposition and annealing. The columnar structure of LNO film provides the low resistivity value ρ~700 µOhm·cm and is well suited to lead zirconate-titanate (PZT) film growth with perfect crystalline structure and ferroelectric performance. These results extend the understanding of columnar grain growth via CSD techniques and may enable the development of new materials and devices for distinct applications. Full article

Abstract

The development of multifunctional nanomaterials has received growing research interest, thanks to its ability to combine multiple properties for severing highly demanding purposes. In this work, holmium oxide nanoparticles are synthesized and characterized by various tools including XRD, XPS, and TEM. These nanoparticles are found to emit near-infrared fluorescence (800–1100 nm) under a 785 nm excitation source. Imaging of the animal tissues was demonstrated, and the maximum imaging depth was found to be 2.2 cm. The synthesized nanoparticles also show the capability of facilitating dye (fluorescein sodium salt and rhodamine 6G) degradation under white light irradiation. The synthesized holmium oxide nanoparticles are envisioned to be useful for near-infrared tissue imaging and dye-degradation. Full article

Abstract

As a promising technology, microreactors have been regarded as a potential candidate for heterogeneous catalytic reactions as they inherently allow the superior advantages of precise flow control, efficient reactant transfer, flexible operation, etc. However, the wide market penetration of microreactors is still facing severe challenges. One of the most important reasons is the preparation of a high–performance catalytic layer in the microreactor because it can directly influence the catalytic activity and stability the reactor and thus the deployment the microreactor technology. Hence, significant progress in depositing nanocatalysts in microreactors has been made in the past decades. Herein, the methods, principles, recent advances, and challenges in the preparation of the catalyst layer in microreactors were presented. A general description of the physicochemical processes of heterogeneous catalytic reactions in microreactors were first introduced. Then, recent advances in catalyst layer preparation in microreactors were systematically summarized. Particular attention was focused on the most common sol–gel method and its latest developments. Some new strategies proposed recently, including bio–inspired electroless deposition and layer–by–layer self–assembly, were also comprehensively discussed. The remaining challenges and future directions of preparing the catalytic layer in microreactors with high performance and low cost were highlighted. Full article
