“…As known from previous studies, by adding particles or other polymers into PAN polymer, the diameter of nanofibers increases compared to pure PAN nanofibers [ 58 , 82 ]. Furthermore, the dimensional stability under thermal treatment is improved and the nanofiber mats contract less, are more flexible and not as fragile compared to pure PAN nanofiber mats [ 58 , 69 , 86 ].…”

“…The SPAD arrays can be considered as solid-state detectors providing imaging capabilities at the single photon level and are used in areas of data and telecommunication security, quantum key distribution applications, advanced driver assistance systems, fluorescence detection, remote-sensing technology, biophotonics, and robotics [ 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 ]. Advantages of SPADs include unprecedented photon counting and time-resolved performance, and therefore they can be used when deep sub-nanosecond timing performance is required [ 63 , 64 , 68 ].…”

Electrospinning enables simple and cost-effective production of magnetic nanofibers by adding nanoparticles to a polymer solution. In order to increase the electrical conductivity of such nanofibers, the carbonization process is crucial. In this study, the chemical and morphological properties of magnetic nanofiber mats prepared from polyacrylonitrile (PAN)/magnetite were investigated. In our previous studies, PAN/magnetite nanofiber mats were carbonized at 500 °C, 600 °C, and 800 °C. Here, PAN/magnetite nanofiber mats were carbonized at 1000 °C. The surface morphology of these PAN/magnetite nanofiber mats is not significantly different from nanofiber mats thermally treated at 800 °C and have remained relatively flexible at 1000 °C, which can be advantageous for various application fields. The addition of nanoparticles increased the average fiber diameter compared to pure PAN nanofiber mats and improved the dimensional stability during thermal processes. The high conductivity, the high magnetization properties, as well as shielding against electromagnetic interference of such carbonized nanofibers can be proposed for use in single photon avalanche diode (SPAD), where these properties are advantageous.

“…Other techniques for SPADs time-gating were proposed in the following years; some examples can be found in Refs. [80][81][82][83][84][85][86][87][88][89][90][91][92]. However, it is worth noting that: (i) none of them (apart the one proposed in Ref.…”

This work reviews physical concepts, technologies and applications of time-domain diffuse optics based on time-gated single-photon detection. This particular photon detection strategy is of the utmost importance in the diffuse optics field as it unleashes the full power of the time-domain approach by maximizing performances in terms of contrast produced by a localized perturbation inside the scattering medium, signal-to-noise ratio, measurement time and dynamic range, penetration depth and spatial resolution. The review covers 15 years of theoretical studies, technological progresses, proof of concepts and design of laboratory systems based on time-gated single-photon detection with also few hints on other fields where the time-gated detection strategy produced and will produce further impact.
