Special Issue Information

Dear Colleagues,

The aim of this Special Issue is to stimulate the scientific exchange of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the application of crystalline materials in industry.

We cordially invite you to publish the latest scientific results, both theoretical and experimental, concerning the nucleation and growth kinetics of metals, semiconductors, superconductors, and magnetic materials, both in the form of single crystals and thin polycrystalline layers.

Recent achievements in the synthesis and growth of monocrystalline and polycrystalline materials have expanded their potential for a wide range of existing and prospective applications, including optics and electronics, as well as biomedicine, quantum computing, etc. Therefore, they are important materials with a bright future in both basic model research in the field of solid-state physics and chemistry and engineering applications.

We invite you to contribute to this Special Issue of Crystals, entitled “Synthesis, Structure and Property Analysis of Crystalline Layers,” which is intended to serve as a multidisciplinary forum covering broad aspects of the science, technology, and applications of a broad range of crystalline materials.

Aluminum oxide (Al2O3) films have been investigated for use in various applications, and numerous deposition techniques have been reported. The spray synthesis method has the advantage of forming a thin layer of crystal at low temperatures using the appropriate precursors. A precursor prepared by diluting Methylaluminoxane with N-methyl pyrrolidone was sprayed onto a porous membrane while varying conditions such as the substrate temperature, feeding speed, and spray amount. The solution penetrated the film during spray application, and the ultra-thin layers deposited on the side wall of the internal pores were observed using a cross-sectional transmission electron microscope (XTEM). The lattice image obtained using the TEM and the composition analysis conducted using a scanning TEM and an energy-dispersive X-ray spectroscope suggest that this thin layer is a layer of Al2O3. The formation of Al2O3 occurred at lower temperatures than in previous reports. This is a major advantage for applications with low-melting-point materials. The most suitable spraying conditions were determined based on the state of deposition on the surface and inside the membrane. These conditions were applied to a three-layer separator for lithium-ion batteries and their effect on thermal stability was investigated. Through heating experiments and XRD analysis, it was confirmed that the shrinkage and melting of the separator are suppressed by spraying. This process can be expected to have wide applications in low-melting-point materials such as polyolefin. Full article

There are high demands for the early and reliable detection of metal components used in safety-critical structures. Nondestructive testing (NDT) is a pivotal technique used across industries to assess a material’s integrity without causing damage and has been used in early crack detection of metals, mainly based on changes in the crystal structure and magnetic properties of metals. This review provides an overview of internal and external detection technology based on nondestructive testing methods such as ultrasonic, electromagnetic, ray, magnetic particle, etc. Especially, the integration of advanced methodologies such as machine learning and artificial intelligence deserves a place in NDT methods. Furthermore, the multifactorial detection method is promoted to enhance the sensitivity and detection range due to advantage integration but still has emerging challenges for safer equipment and applications. The review aims to compare these methods and outline the future challenges of NDT technologies for metal crack detection. Full article
