Nano-hydroxyapatite (HA) was directly synthesized on a silk fibroin (SF) template using the property of SF being soluble in a concentrated CaCl(2) solution as a HA source of calcium at pH 7.4 and room temperature. The microstructure and bonding state were investigated by x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential(More)
Chitosan fibers were introduced into a poly(L-lactic acid)/beta-tricalcium phosphate (PLLA/beta-TCP) matrix as reinforcement to prepare scaffold materials for bone tissue engineering with adequate initial strength and a feasible degradation rate. The structure and morphology of the composites were observed by a scanning electron microscope (SEM). The(More)
Cylinder- and bamboo-shaped boron nitride nanotubes (BNNTs) have been synthesized in large scale via a facile chemical vapor reaction route using ammonia borane as a precursor. The structure and chemical composition of the as-synthesized BNNTs are extensively characterized by X-ray diffraction, scanning electron microscopy, high-resolution transmission(More)
Silicon carbide (SiC), a compound of silicon and carbon, with chemical formula SiC, the beta modification ( β-SiC), with a zinc blende crystal structure (similar to diamond), is formed at temperature below 1700°C. β-SiC will be the most suitable ceramic material for the future hard tissue replacement, such as bone and tooth. The in vitro cytotoxicity of(More)
We report a new type of core-shell heterostructure consisting of a rod-like NiCo2S4 (NCS) core and an urchin-like Ni(1-x)Co x (OH)2 (NCOH) shell via a simple hydrothermal route coupled with a facile electrodeposition. NCS nanorod arrays (NRAs) can not only act as excellent electrochemically active materials by themselves, but they can also serve as(More)
Novel SiOC nanocomposites were successfully synthesized from commercial silica sol and sucrose via a simply designed route. The formation of SiOC nanocomposites was studied using thermogravimetry and differential scanning calorimetry. The synthesized nanocomposites were characterized by Fourier transform infrared spectroscopy, x-ray fluorescence(More)
We rationally designed a facile two-step approach to synthesize ZnMn2O4@G composite anode material for lithium-ion batteries (LIBs), involving a template-free fabrication of ZnMn2O4 nanorings and subsequent coating of graphene sheets. Notably, it is the first time that ring-like ZnMn2O4 nanostructure is reported. Moreover, our system has been demonstrated(More)
We demonstrate that novel three-dimensional (3D) B(OH)3 and α-Fe2O3 nanoparticles decorated carbon microspheres (B(OH)3/α-Fe2O3-CMSs) can be fabricated via a facile thermal treatment process. The carbon microspheres with diameter of 1-3μm and decorated B(OH)3 and α-Fe2O3 nanoparticles with diameters of several to tens of nanometers are successfully(More)
Carbon nanofibers decorated with porous carbon nanotubes have been prepared by electrospinning and annealing methods. Microwave reflection loss of the products is investigated in the frequency range of 2-18 GHz. The bandwidth with a reflection loss less than -10 dB covers a wide frequency ranging from 7.0 to 14.1 GHz with the thickness of 3.0-5.5 mm, and(More)
The structural stability, electronic and optical properties of α-Si3N4 nanobelts orientating along the different directions with surface H, F and Cl modifications are investigated using first-principles methods. The stabilities of α-Si3N4 nanobelts are greatly affected by the surface modifications and increased in the order of H, Cl and F. All the modified(More)
