Special Issue Information

Dear Colleagues,

The importance of developing advanced miniaturized devices cannot be emphasized enough, especially in the era of the fourth industrial revolution (4IR), because the underlying hardware technologies driving the 4IR are closely associated with the miniaturized devices. For example, miniaturization of electronic devices has led to remarkable achievements in various 4IR applications, such as sensors, robotics, the Internet of Things (IoT), 3D printings, etc., by improving the degree of integration of microchips, enhancing the cooling performance, etc. While various manufacturing processes have enabled scientists and engineers to achieve these rapid advances in miniaturization technologies, in particular, fiber forming techniques and their resulting micro- and nanofibers have overcome numerous challenges and achieved remarkable breakthroughs over the past few years. Such light and flexible but sturdy one-dimensional (1D) fibrous materials, along with cost-effective and scalable fabrication processes, hold great promise for further achievements in fields for miniaturization technologies.

This Special Issue aims to provide and highlight current research progresses on advanced miniaturized devices based on micro- and nanofibers (fabricated by various fiber forming methods, including electrospinning, solution blowing, to name a few), which will be of great value to the community pertaining to miniaturization technologies.

This study presents the doping of higher alkanes, namely, pentadecane (C15) and hexadecane (C16), with ZnS:Mn nanoparticles to create new types of in-line optical fiber sensors with unique optical properties. In this research, the phenomenon of light beam leakage out of the taper and its interaction with the surrounding materials is described. The fabricated new materials are used as cladding in a tapered optical fiber to make it possible to control the optical light beam. The manufactured sensor shows high sensitivity and fast response to the change in the applied materials. Results are presented for a wide optical range of 1200–1700 nm with the use of a supercontinuum source and an optical spectrum analyzer, as well as for a single wavelength of 800 nm, corresponding to the highest transmitted power. The results present a change in the optical property dependence on the temperature in the cooling and heating process. For all materials, the measurements in a climatic chamber are provided between 0 and 40 °C, corresponding to the phase change of the alkanes from solid to liquid. The addition of nanoparticles to the volume of alkanes is equal to 1 wt%. To avoid a conglomeration of nanoparticles, the anti-agglomeration material, Brij 78 P, is used. Full article
