Special Issue Information

Dear Colleagues,                

The utilization of nanofibers in technologies for a wide array of applications continues to represent both an important area of fundamental academic interest and commercial research. We invite authors to contribute original research articles or comprehensive review articles covering the most recent progress and new developments in the design and utilization of nanofibers for novel devices and fundamental studies relevant to applications in energy, biomedical engineering, environmental engineering, and sensing. This Special Issue aims to cover a broad range of subjects, from nanofiber synthesis to the design and characterization of nanofiber devices and technologies for a number of applications. The format of welcomed articles includes full papers, communications, and reviews. Potential topics include but are not limited to the following:

  • Preparation and characterization of nanofibers;
  • Novel methodologies for alignment, patterning, and scale-up of nanofibers;
  • Techniques for the improvement of nanofiber sensing properties;
  • Nanofiber-based composites for sensing applications;
  • Nanofibers for in vitro and in vivo sensing applications;
  • Applications of nanofibers as biomaterials and biomedical sensors;
  • Natural nanofiber applications;
  • Applications of nanofibers associated with renewable energy and sustainability;
  • Theoretical investigations on the preparation or applications of nanofibers;
  • Applications of nanofibers associated with environmental remediation and detection;
  • Prospects on advances, opportunities, and challenges of nanofiber applications.

:A plasmonic sensor based on a dual-side polished photonic crystal fiber operating in a telecommunication wavelength range is proposed and investigated numerically by the finite element method (FEM). We study the effects of structural parameters on the sensor’s performance and analyze their tuning effects on loss spectra. As a result, two configurations are found when the analyte refractive index (RI) changes from 1.395 to 1.415. For configuration 1, an RI resolution of 9.39 × 10−6, an average wavelength sensitivity of 10,650 nm/RIU (the maximum wavelength sensitivity is 12,400 nm/RIU), an amplitude sensitivity of 252 RIU−1 and a linearity of 0.99692 are achieved. For configuration 2, the RI resolution, average wavelength sensitivity, amplitude sensitivity and linearity are 1.19 × 10−5, 8400 nm/RIU, 85 RIU−1 and 0.98246, respectively. The combination of both configurations can broaden the wavelength range for the sensing detection. Additionally, the sensor has a superior figure of merit (FOM) to a single-side polished design. The proposed sensor has a maximum wavelength sensitivity, amplitude sensitivity and RI resolution of the same order magnitude as that of existing sensors as well as higher linearity, which allows it to fulfill the requirements for modern sensing of being densely compact, amenable to integration, affordable and capable of remote sensing.

In this study, we report on the fabrication and utilization of NiCr alloy nanoparticles (NPs)-decorated carbon nanofibers (CNFs) as efficient and competent non-precious catalysts for the hydrolytic dehydrogenation of ammonia borane (AB) at 25 ± 2 °C. The introduced NFs have been fabricated in one step using a high-temperature thermal decomposition of the prepared electrospun nanofiber mats (nickel acetate tetrahydrate, chromium acetate dimer, and polyvinyl alcohol) in an inert atmosphere. The chemical composition of the NFs with different proportions of Ni1−xCrx (x = 0.0, 0.1, 0.15, 0.2, 0.25, 0.3) was established via standard characterization techniques. These techniques proved the formation of disorder Cr2Ni3 alloy and carbon for all the formulations. The as-synthesized composite NFs exhibited a higher catalytic performance for AB dehydrogenation than that of Cr-free Ni–CNFs. Among all the formulations, the sample composed of 15% Cr shows the best catalytic performance, as more H2 was released in less time. Furthermore, it shows good stability, as it is recyclable with little decline in the catalytic activity after six cycles. It also demonstrates the activation energy, entropy (ΔS), and enthalpy (ΔH) with 37.6 kJ/mole, 0.094 kJ/mole, and 35.03 kJ/mole, respectively. Accordingly, the introduced catalyst has a lower price with higher performance encouraging a practical sustainable H2 energy application from the chemical hydrogen storage materials. Full article
