Dural defects are a common problem in neurosurgical procedures and should be repaired to avoid complications such as cerebrospinal fluid leakage, brain swelling, epilepsy, intracranial infection, and so on. Various types of dural substitutes have been prepared and used for the treatment of dural defects. In recent years, electrospun nanofibers have been applied for various biomedical applications, including dural regeneration, due to their interesting properties such as a large surface area to volume ratio, porosity, superior mechanical properties, ease of surface modification, and, most importantly, similarity with the extracellular matrix (ECM). Despite continuous efforts, the development of suitable dura mater substrates has had limited success. This review summarizes the investigation and development of electrospun nanofibers with particular emphasis on dura mater regeneration. The objective of this mini-review article is to give readers a quick overview of the recent advances in electrospinning for dura mater repair.

“…The hybridized (nickel-cobalt-oxygen-CNFs) nanocomposites exhibited good supercapacitance performance with a specific capacitance of 836 F g −1 and retention of 80.9% after 2000 cycles. In addition, electrospinning technology is more attractive and promising for practical applications due to its ease of operation, environmental friendliness, and large-scale production capacity [18,[25][26][27][28][29].…”

The preparation of composite carbon nanomaterials is one of the methods for improving the electrochemical performance of carbon-based electrode materials for supercapacitors. However, traditional preparation methods are complicated and time-consuming, and the binder also leads to an increase in impedance and a decrease in specific capacitance. Therefore, in this work, we reduced Ni-Cu nanoparticles on the surface of nitrogen-doped carbon nanofibers (CNFs) by employing an electrostatic spinning method combined with pre-oxidation and annealing treatments. At the same time, Ni-Cu nanoparticles were vulcanized to Ni–Cu–S nanoparticles without destroying the structure of the CNFs. The area-specific capacitance of the CNFs/Ni–Cu–S–300 electrode reaches 1208 mF cm−2 at a current density of 1 mA cm−2, and the electrode has a good cycling stability with a capacitance retention rate of 76.5% after 5000 cycles. As a self-supporting electrode, this electrode can avoid the problem of the poor adhesion of electrode materials and the low utilization of active materials due to the inactivity of the binder and conductive agent in conventional collector electrodes, so it has excellent potential for application.

GeSe2 anode materials possess energy densities higher than those of the commercial graphite anode for lithium-ion batteries (LIBs). However, the limited cycling life and poor inherent conductivity present significant difficulties for their use in various fields. LIBs’ lifetime and capacity density depend on their electrode materials, where structural stability and a slow diffusion control mechanism are crucial factors. In this study, amorphous nanosize GeSe2 uniformly anchored on graphite sheets (GeSe2/G) was prepared using ball milling. For comparison, the cycle performances of pure GeSe2 and GeSe2 with the same ball milling conditions (M-GeSe2) were tested. The results showed that ball milling enabled uniform anchoring of GeSe2 nanoparticles of ∼200 nm on graphite nanosheets without aggregation, where the introduction of graphite not only served as electron transfer layers to effectively improve the electrical conductivity but also assisted in reducing the volume growth and comminution of GeSe2 during Li+ insertion/extraction procedures. When served as anode materials for LIBs, the GeSe2/G nanocomposites showed high Li+ storage properties, i.e., a high reversible capacity of 812.8 mAh g–1 at 0.1 A g–1. After 50 cycles, GeSe2/G still reached 650 mAh g–1, which was much higher than M-GeSe2 (392.3mAh g–1) and GeSe2 (183 mAh g–1). Even at 1 A g–1, the GeSe2/G anode exhibited a high reversible capacity of 409.6 mAh g–1 and remarkable cycling stability, with a high capacity retention of 63% after 300 cycles.
