Electrospinning is a prominent technique for micro/nanofiber production and has received significant attention in the 21st century. It enables the production of ultrafine fibers using a variety of polymers, including synthetic, natural, and hybrid materials. Electrospun nanofibers (NFs) possess unique properties such as a high surface‐to‐volume ratio, tunable pore structures, and customizable composition, making them highly desirable in various fields such as biomedical science, textiles, sensors, filters, energy, and packaging. Here, particular attention will be given to the application of NFs in biomedical fields. The use of NFs for the delivery of drugs, growth factors, proteins, nanoparticles (NPs), etc., holds significant promise in the field of biomedical science. To combine these compounds with NFs, various electrospinning techniques have been developed with outstanding improvements, and based on the requirements of the application type, different electrospinning processes are favored. In this review, the most common drug loading methods into NFs, generally used synthetic/natural polymers for NF production, and their application in drug delivery systems, tissue engineering, and wound dressing will be mentioned. Finally, challenges and future perspectives for above mentioned biomedical applications were discussed.This article is protected by copyright. All rights reserved.

Hierarchical porous nanowire-like MoS 2 /CoNiO 2 nanohybrids were synthesized via the hydrothermal process. CoNiO 2 nanowires were selected due to the edge site, high surface/volume ratio, and superior electrochemical characteristics as the porous backbone for decoration of layered MoS 2 nanoflakes to construct innovative structure hierarchical three-dimensional (3D) porous NWs MoS 2 /CoNiO 2 hybrids with excellent charge accumulation and efficient ion transport capabilities. Physicochemical analyses were conducted on the developed hybrid composite, revealing conclusive evidence that the CoNiO 2 nanowires have been securely anchored onto the surface of the MoS 2 nanoflake array. The electrochemical results strongly proved the benefit of the hierarchical 3D porous MoS 2 /CoNiO 2 hybrid structure for the charge storage kinetics. The synergistic characteristics arising from the MoS 2 /CoNiO 2 composite yielded a notably high specific capacitance of 1340 F/g at a current density of 0.5 A/g. Furthermore, the material exhibited sustained cycling stability, retaining 95.6% of its initial capacitance after 10 000 long cycles. The asymmetric device comprising porous MoS 2 /CoNiO 2 //activated carbon encompassed outstanding energy density (93.02 Wh/kg at 0.85 kW/kg) and cycling stability (94.1% capacitance retention after 10 000 cycles). Additionally, the successful illumination of light-emitting diodes underscores the significant potential of the synthesized MoS 2 /CoNiO 2 (2D/1D) hybrid for practical high-energy storage applications.

The Volumetric Homogenization Method (VHM) is one of the most commonly used methods for neutronics calculation in reactors or components. However, the use of VHM for the Double-Heterogeneous (DH) System may lead to a large deviation in reactivity calculation. The deviation of DH System using the VHM can be expressed by the theoretically modified optical length. When the theoretically modified optical length is less than 10−4, the deviation caused by the VHM will be less than 100 pcm. This paper points out that the existing theoretically modified optical length for some cases of DH systems is not accurate, and this method is only for pin cell. In this paper, by calculating a series of DH models and their corresponding VHM models, it is found that the water-uranium ratio and the shape of fuel region seriously affects the reactivity calculation deviation of particle-dispersed fuel, the original modified optical length does not take this into account, resulting in unacceptable errors. On this basis, the application of optical length to physical boundaries for DH system is further discussed and the shape correction factor is taken into consideration. Therefore, an improved optical length is proposed, which greatly expands the range of application of the physical boundary judgment methods for the double heterogeneity of dispersed particle fuel. The numerical results show that the accuracy of the improved optical length in defining the physical boundary of double heterogeneous system is higher than the theoretically modified optical length.
