Special Issue Information
Dear Colleagues,
Liquid crystal (LC), as a smart soft material, has a lot of fascinating properties, including self-assembly, stimuli responsiveness, and birefringence. In the past few decades, LC materials have been widely investigated in state-of-the-art research, serving as enabling technology building blocks. Here, we highlight a few critical and unique properties of LCs and their applications. (1) LC small molecules are mobile and can self-assemble into complex structures, which enable designing and tailoring dynamic material surfaces and interfaces. The thermal-induced and light-induced phase transition enables smart windows with LC shading and actuators with LC elastomers. (2) Sensitive to electric field, magnetic field, temperature, light exposure, and pressure, LC polymers can change the alignment and yield mechanical responses. Therefore, LC-based sensors and actuators have been applied in the fields of soft robotics, flexible electronics, biomedicine, etc. (3) LCs are birefringent, which allows for phase modulation, polarization modulation, and intensity control through the spectrum of UV, visible, infrared, and microwave. The optoelectronic tuning makes LCs a mainstream solution to displays and spatial light modulators. The ability of surface patterning and volume patterning opens the door to flat optics, which significantly reduces the size and weight of AR/VR devices, microscopes, and Lidar sensors. This Special Issue aims to collect innovative work on LC materials and applications to accelerate LC research for science and technology development.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
