“…A glass slide with patterned Au electrodes was attached to the steel substrate to collect the electrospun nanofibers. After collection, the nanofibers were sintered in air at 480 • C for 1 h to remove the PVP and obtain NiO nanofibers on the glass substrate, devoted to gas sensing application [87]. The nickel nitrate used as Ni precursor dissolved in water/ethanol using poly(vinyl alcohol) (PVA) polymer demonstrated an average diameter of 58 nm for the nanofibers, which is three-fold smaller than the fibers prepared in other solvents and can be explained by the high dynamic viscosity, the high surface tension, and the high conductivity of the solution (water/ethanol).…”

The review paper provides a comprehensive analysis of nickel oxide (NiO) as an emerging material in environmental monitoring by surveying recent developments primarily within the last three years and reports the growth processing and strategies employed to enhance NiO sensing performance. It covers synthesis methods for pristine NiO, including vapor-phase, liquid-phase, and solution-processing techniques, highlighting advantages and limitations. The growth mechanisms of NiO nanostructures are explored, with a focus on the most recent research studies. Additionally, different strategies to improve the gas sensing performance of NiO are discussed (i.e., surface functionalization by metallic nanoparticles, heterostructure formation, carbon-based nanomaterials, and conducting polymers). The influence of these strategies on selectivity, sensitivity, response time, and stability of NiO-based sensors is thoroughly examined. Finally, the challenges and future directions that may lead to the successful development of highly efficient NiO-based gas sensors for environmental monitoring are introduced in this review.

“…Additionally, coaxial electrospinning provides the opportunity to make hybrid fibers out of two or more completely different materials, with each material adding a different functionality to a single fiber, allowing the use of such a fiber for various applications . Oxide-based nanofibers have carved a niche as gas sensors either by conductivity , or by optical properties . Conducting additives like carbon nanotubes (CNTs), graphene, etc., have been utilized to enhance the conductivity of a conducting polymer or to induce it in a usually insulating fiber .…”

This article adds a new direction to the functional capability of protein-protected atomically precise gold clusters as sensors. Counting on the extensively researched intense luminescence of these clusters and considering the electron donating nature of select amino acids, we introduce a dual probe sensor capable of sensing changes in luminescence and conductivity, utilizing bovine serum albumin-protected atomically precise gold clusters hosted on nanofibers. To this end, we have also developed a hybrid nanofiber with a conducting core with a porous dielectric shell. We show that clusters in combination with nanofibers offer a highly selective and sensitive platform for the detection of trace quantities of trinitrotoluene, both in solution and in the vapor phase. In the solution phase, trinitrotoluene (TNT) can be detected down to 1 ppt at room temperature, whereas in vapor phase, 4.8 × 109 molecules of TNT can be sensed using a 1 mm fiber. Although the development in electrospinning techniques for fabricating nanofibers as sensors is quite substantial, a hybrid fiber with the dual properties of conductivity and luminescence has not been reported yet.
