Derivated titanate nanotubes and their hydrogen storage properties

02-Jan-2010 | Zheng Chang, Jing Liu, Xiaoming Sun, Junfeng Liu, Frontiers of Chemistry in China, 2010

Titanate nanotubes and their derivates, Pd-loaded and Co2+, Zn2+, Cu2+, and Ag+ ion-exchanged titanate nanotubes, were respectively prepared and characterized by XRD, HR-TEM, and EDS. Their hydrogen storage properties were investigated, and the results revealed that the derivated titanate ...

Biocompatibility and in vitro antineoplastic drug-loaded trial of titania nanotubes prepared by anodic oxidation of a pure titanium

19-Dec-2009 | XiLin Xiao, LiXia Yang, ManLi Guo, ChunFeng Pan, QingYun Cai, ShouZhuo Yao, Science in China Series B: Chemistry, 2009

TiO2 nanotube (NT) arrays have been prepared by anodic oxidation of a Ti sheet, and carbon-deposited TiO2 NT arrays have been prepared by annealing TiO2 NT arrays in carbon atmosphere. The biocompatibility of the as-prepared NT arrays was investigated by observing the growth of osteosarcoma ...

Effect of electrooptical memory in suspensions of carbon nanotubes in liquid crystals

11-Nov-2009 | L. A. Dolgov, N. I. Lebovka, O. V. Yaroshchuk, Colloid Journal, 2009

Electrooptical response and microstructure of dispersions of multiwall carbon nanotubes in N-(4-ethoxybenzilidene)-4-n-butyl aniline nematic liquid crystal (LC) are studied. Irreversible response on the applied electric field (electrooptical memory) was revealed in oriented layers of such ...

Role of nanofiller in friction of polymers based on polycaproamide: Indirect effect

05-Nov-2009 | A. P. Krasnov, O. V. Afronicheva, V. A. Mit’, V. B. Bazhenova, T. V. Volkova, O. V. Sinitsyna, Ya. S. Vygodskii, I. ..., Journal of Friction and Wear, 2009

The effect of nanofillers (multiwalled carbon nanotubes) on the tribological behavior of polycaproamide is studied when introduced into the polymer by polymerization filling. The introduction of insignificant quantities (∼0.1 wt %) of nanotubes provides their homogeneous distribution in the ...

Alteration of the mechanical behaviour of polypropylene owing to successive introduction of multiwall carbon nanotubes and stretching

18-Sep-2009 | D. T. G. Katerelos, R. Joffe, D. Labou, L. Wallstrom, Mechanics of Composite Materials, 2009

Stretching effects on the morphology of polypropylene/carbon nanotube composites is the focus of this work. The material under investigation was composed of isotactic polypropy lene (iPP) and multiwall car bon nanotubes (MWCNTs) in amount of 0.5 wt.%. The iPP and CNTs were mixed under sonication ...

Aligned Nanorod Arrays: Additive and Emergent Properties

07-Jul-2009 | Pushan Ayyub, Journal of Cluster Science, 2009

Studies of one-dimensional nanostructures of various types (such as quantum wires, nanorods, nanotubes and nanobelts) have progressed substantially during the past decade and have been reviewed by a number of authors. Here, we provide a concise overview of the synthesis and special properties of ...

Recent Progress in the Study of Inorganic Nanotubes and Fullerene-Like Structures

07-Jul-2009 | R. Tenne; G. Seifert, Annual Review of Materials Research, 2009

The synthesis of WS2 inorganic nanotubes (INT) and inorganic fullerene-like (IF) structures in 1992 signified the opening of a fertile and challenging field of scientific endeavor. These structures were the first of a long and ever-expanding series of INT and IF structures. Although initially ...

Quantum-chemical modelling of nanotubes of titanium silicocarbides Ti2SiC, Ti3SiC2, and Ti4SiC3

29-Jun-2009 | A. N. Enyashin, A. L. Ivanovskii, Theoretical and Experimental Chemistry, 2009

Atomic models are proposed for nanotubes of the titanium silicocarbides Ti2SiC, Ti3SiC2, and Ti4SiC3, and their electronic structure and interatomic interactions are investigated by the density functional tight-binding method (DFTB) in comparison with the corresponding crystalline phases.
