the bone mineral consists of tiny hydroxyapatite (ha) crystals in the nanoregime. nanostructured ha is also expected to have better bioactivity than coarser crystals. this paper reports on the in vitro evaluation of bone like ha nanopowders. the prepared ha nanopowder was characterized for its phase purity, chemical homogeneity and bioactivity. fourier transform infrared (ft-ir) spectroscopy wa...

in a hydrothermal route devoted for synthesis of ca10(po4)6(oh)2 (ha) nanostructures, morphology can be controlled by experimental condition to form magical ha or nanostructured nanoparticles. in an intermediate condition, a novel nanostructure namely rose-like bundle of ha rod-likes was found, which is different from known ha nanostructures. the chemical synthesis of nanopowders under hydrothe...

The use of co-deposition instead of sequential deposition during the preparation of Pd–Ag thin films by electroless plating deposition leads to two different nanostructures, e.g. a dendritic nanostructure or a more compact and dense film, allowing to analyze the role of this parameter, at equal membrane composition, on the performances. In pure H2 the permeability to hydrogen of the second type...

Micro–Nanostructure-Assisted Luminescence The micro-nanostructure engineering provides an effective strategy for improving the luminescent characteristics of perovskite materials and optoelectronics. In article number 2100084, Yan-Qing Li, Jian-Xin Tang, co-workers summarize recent developments micro–nanostructure-assisted optical manipulation approaches to enhance photo/electroluminescence emi...

DOI: 10.1002/adom.201600356 of the local environment. [ 5 ] Confi nement of plasmon modes to a surface of metal nanostructures under the constraints imposed by the fi nite boundaries of the nanostructure alters their dispersion, only allowing for discrete solutions. In the quasi-static limit, where the wavelength of the excitation light is much larger than the size of the nanostructure, the nan...

Current applications of carbon-based supercapacitors are limited by their low energy density. One promising strategy to enhance the energy density is to couple metal oxides with carbon materials. In this study, a porous MnCo2O4.5 nanoneedle/carbon aerogel hybrid nanostructure was synthesized by assembling MnCo2O4.5 nanoneedle arrays on the surface of channel walls of hierarchical porous carbon ...

beryllium  oxide  (beo)  nanopowder  was  synthesized  using  sol-gel method  and  the  effects  of  changes of  chemical  reagents  were investigated.  because  of  tissue  equivalence  and  other  outstanding thermoluminescence  (tl) properties of  the bulk material  in x and γ dosimetry, the applicability of this nanostructure in tl dosimetry was studied  following  irradiation to  the 137 c...

A novel type of 1D nanostructure with characteristics between those of a solid nanowire and a hollow nanotube, i.e. a peashell-like nanostructure comprising a 1D wire with periodically embedded hollow nanobubbles, is presented for the first time; as an example, MgO peashell-like nanostructures exhibit extraordinary dielectric and magnetization properties.
