“…In addition, BG is the only one, which could bond to hard and soft tissue (7,8). Recent studies showed that the degradation products of bioactive glasses could stimulate the production of growth factors, cell proliferation and activate the gene expression of osteoblast (9)(10)(11)(12)(13)(14). Recent studies showed that increasing specific surface area and pore volume of BG may greatly accelerate the deposition process of hydroxyapatite (6).…”

Nano-bioactive glass (NBG) was prepared via sol-gel method and freeze-dried technique using polyethylene glycol (PEG) as templates. The influences of molecular weight and content of polyethylene glycol on the morphology and the size NBG particles were investigated. The optimal sintering temperature of NBG was determined by using thermal gravimetric (TG) and differential thermal analysis (DTA), and the NBG particles were characterized by Fourier-transformed infrared (FTIR) spectroscopy, transmission electron microscopy (TEM) and X-ray diffraction (XRD). The XRD pattern of NBG sintered at 650 • C in air confirmed that the calcined glass existed in amorphous state. The results indicated that the PEG molecular weight and PEG content have obvious effects on the morphology and size of the NBG particles. The size of NBG particle prepared with PEG-200 was beyond 1μm and the aggregation was obvious. The size of obtained NBG particle with PEG-10000 was between 50 nm and 80 nm, with a hollow spherical shape; while the morphology of the NBG with PEG-20000 was needle-shaped, with an average width of 20 nm and length of 100 nm. The particle size of the NBG particles decreased with the increase of PEG concentration.

“…Biomineralization in simulated body fluid and in vitro co-culture with MC3T3-E1 osteoblasts revealed the improved ability of CNFs/BG composites to promote the in vitro formation of apatite and MC3T3-E1 proliferation (Figs. 7a-c) [96]. Natural bone is a fiber-reinforced hybrid material composed of type-I collagen fibers and HA minerals.…”

Carbon nanofibers (CNFs) with diameters in the submicron and nanometer range exhibit high specific surface area, hierarchically porous structure, flexibility, and super strength which allow them to be used in the electrode materials of energy storage devices, and as hybrid-type filler in carbon fiber reinforced plastics and bone tissue scaffold. Unlike catalytic synthesis and other methods, electrospinning of various polymeric precursors followed by stabilization and carbonization has become a straightforward and convenient way to fabricate continuous CNFs. This paper is a comprehensive and brief review on the latest advances made in the development of electrospun CNFs with major focus on the promising applications accomplished by appropriately regulating the microstructural, mechanical, and electrical properties of as-spun CNFs. Additionally, the article describes the various strategies to make a variety of carbon CNFs for energy conversion and storage, catalysis, sensor, adsorption/separation, and biomedical applications. It is envisioned that electrospun CNFs will be the key materials of green science and technology through close collaborations with carbon fibers and carbon nanotubes.
