We highlight the recent developments in the preparation of electrospun nanomaterials to produce metal sulfides with distinct chemical and physical properties for a broad range of applications.

Superhydrophobic electromagnetic interference (EMI) materials are becoming increasingly important to the longterm service of outdoor all-weather electrical equipment. It is an urgent need to prepare flexible and robust high-performance EMI shielding materials to work in harsh environments. To this end, we demonstrate a delicate structure design of superhydrophobic EMI shielding material that possesses desired properties via chemical deposition of silver nanocluster on electrospun polymer nanofibers followed by stearic acid (SA) modification. The porous electrospun hybrid membrane with a spatially distributed silver coating enabled excellent electrical conductivity up to 57 319 S cm −1 . Notably, superior EMI shielding effectiveness (SE) of 90.14 dB in an ultrabroadband frequency range is achieved in conjugation with the specific shielding effectiveness (SSE/t) of 14 253 dB cm 2 g −1 , owing to the combined effects of favorable porous structure and interfacial polarization. The thin coating of the SA layer endowed the film with superhydrophobicity (water contact angle up to 156.7°) and superior corrosion resistance with only 6.56% loss in EMI SE after 40 days incubation in the salt spray tank. The integrated functionalities being achieved in the hybrid membrane, such as high resistance to mechanical deformation (3.55% loss in EMI SE after 2000 times of bending), self-cleaning property, long-term (12 months) performance stability under high mechanical and chemical tolerance, offer great promise for outdoor all-weather electronic equipment under harsh environments.

Isoniazid is an antibiotic primarily used in clinical treatment of tuberculosis, but excessive usage can lead to serious consequences such as hepatotoxicity, neurotoxicity, and even coma and death. Therefore, it is critical to exploit a quick, facile, and acute way for isoniazid analysis. In this work, we have demonstrated an efficient electrospinning–carbonation–wet chemistry reaction–calcination process to fabricate CuO/NiO nanotubes (NTs) as a promising nanozyme for peroxidase (POD) mimicking. In virtue of the distinct tubular structure and synergy between CuO and NiO from the mechanisms of both electron transfer and hydroxyl radical generation, a remarkably improved catalytic activity is realized for the CuO/NiO NTs compared with bare CuO and NiO samples. According to the admirable POD-like property, a rapid colorimetric detection for isoniazid is accomplished with a detection limit of 0.4 μM (S/N = 3) and favorable selectivity. In addition, the sensing capability of isoniazid in a real sample is also investigated with satisfactory results. This work offers a novel tactic to fabricate high-performance nanozymes with efficient isoniazid sensing capabilities to address challenges in disease treatment efficacy and public safety monitoring.
