Hydrogels are synthetic or natural polymer networks crosslinked either chemically or physically to maintain 3D structures that are able to absorb and retain large amounts of water. [ 1 ] Porous biocompatible hydrogels combine porosity with biocompatibility and play an important role in various biomedical applications, such as scaffold materials in tissue engineering, cell transplantation, and …
Abstract. Using Mn(NO3)2 and ozone as raw materials, b-MnO2 nanowires with diameters of about 6–12 nm, lengths of 2–5 mmand surface area of 73.54 m2 g-1 were synthesized by a simple hydrothermal process. The influences of synthesis conditions such as hydrothermal temperature, reaction time and ozone were investigated, and the growth process of b-MnO2 nanowires was discussed. The cataly…
A facile, green, low cost and efficient one-step technology to synthesize highly dispersible functional single-walled and multiwalled carbon nanotubes (f-SWNTs and f-MWNTs) up to supergrams is reported. Large-scale (up to hundreds of grams) synthesis of functional azides was developed at first, and various reactive groups (i.e., -OH, -NH2, -COOH, and -Br) were then introduced onto the convex…
