Milling time is one of the most important factors for achieving the desired particle size of milled powders. Generally, the particle size of milled powders decreases with increasing milling time. However, long milling time results in agglomeration of small particles for some powders [9]. The using of the NDT method gives lot information about these microstructures in particular the magnetic NDT...

This study investigates the effects of nanostructure size and surface area on the rheological properties of un-cross-linked poly(propylene fumarate) (PPF) nanocomposites and the mechanical properties of cross-linked nanocomposites as a function of the nanostructure loading. Three model carbon nanostructures were examined, C(60) fullerenes, ultra-short single-walled carbon nanotubes (US-tubes) a...

In situ amplitude modulated-atomic force microscopy (AM-AFM) has been used to probe the nanostructure of mixtures of propylammonium nitrate (PAN) with n-alkanols near a mica surface. PAN is a protic ionic liquid (IL) which has a bicontinuous sponge-like nanostructure of polar and apolar domains in the bulk, which becomes flatter near a solid surface. Mixtures of PAN with 1-butanol, 1-octanol, a...

This paper reports dimensional dependence of the mechanical response in carbon nanostructure composites to near-infrared (NIR) light. Using polydimethylsiloxane, a common silicone elastomer, composites were fabricated with one-dimensional multi-wall carbon nanotubes (MWNTs), two-dimensional single-layer graphene, two-and-a-half-dimensional graphene nanoplatelets and three-dimensional highly ord...

The nanostructure of Ce doped OMS-2 plays a very important role in its catalytic property. We demonstrate by density functional theory (DFT) calculations that the unique nanostructure of the Ce ion substituted OMS-2 with Mn vacancy in the framework is beneficial for the improvement of catalytic activity, while the nanostructure of the Ce ion substituted OMS-2 without defects are detrimental to ...

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...

a carbon nanocomposite electrode has been designed by incorporation of montmorillonite nanoclayinto the carbon ionic liquid electrode for the electrochemical determination of amitriptiline . the surface ofthe proposed electrode was characterized by scanning electron microscopy. the presence of ionic liquid asa binder is believed to be responsible for the electrocatalytic activity of the propose...

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...
