Crystals (ISSN 2073-4352) is an open access journal that covers all aspects of crystalline material research in different sections: https://www.mdpi.com/journal/crystals/sections. Crystals provides a forum for the advancement of our understanding of the nucleation, growth, processing, and characterization of crystalline and liquid crystalline materials. Their mechanical, chemical, electronic, magnetic, and optical properties, and their diverse applications, are all considered to be of importance. Additionally, we encourage contributors to send articles focused on crystals research (of small and high molecular weight). Their characterization by using modern techniques for crystal growth and high resolution characterization such as synchrotron radiation and modern methods for the growth of crystals for X-ray free electron lasers (XFELS) would also be welcome. Crystals can be used as a reference and publication source for the crystalline research community. Crystals publishes reviews, regular research articles, short communications and perspectives et al. Our aim is to encourage scientists to publish their experimental, theoretical and computational results in as much detail as possible so that results can be reproduced. Therefore, there is no restriction on article length.
