The electrochemical performances of fluorinated carbon nanofibres have been tested for a use as cathode material in primary lithium battery using LiBF4 PC:DME 1M as electrolyte. For a very narrow fluorination range [420-450°C], the fluorine content in the carbon nanofibres increases up to CF0.78 and so do both the energy and the power densities. A maximum of 8057 W.kg power density has been rea...

Considerable interest has been devoted to converting mechanical energy into electricity using polymer nanofibres. In particular, piezoelectric nanofibres produced by electrospinning have shown remarkable mechanical energy-to-electricity conversion ability. However, there is little data for the acoustic-to-electric conversion of electrospun nanofibres. Here we show that electrospun piezoelectric...

This work describes the application of oxo-derivatives of fullerene C60 and pristine fullerene as a nanocomposite in polymerous nanofibres. In this work we used oxofullerene derivative, of which preparation was presented by the authors of the State office for nuclear safety (Prague) on Nanocon 2009 and on Nanocon 2010 [1, 2]; there was presented its application in vivo as a radioprotective agen...

The objective of this study is to develop a structural nanocomposite of multiple components in the form of core-sheath nanofibres using coaxial electrospinning for the fast dissolving of a poorly water-soluble drug quercetin. Under the selected conditions, core-sheath nanofibres with quercetin and sodium dodecyl sulphate (SDS) distributed in the core and sheath part of nanofibres, respectively,...

The clinical development of neuropeptides has been limited by a combination of the short plasma half-life of these drugs and their ultimate failure to permeate the blood brain barrier. Peptide nanofibres have been used to deliver peptides across the blood brain barrier and in this work we demonstrate that the polymer coating of peptide nanofibres further enhances peptide delivery to the brain v...

In this paper an expedient fabrication of uniform nanofibres from a planar arylene–ethynylene tetracycle molecule is reported. The long-range one-dimensional molecular arrangement, which is mainly due to the favourable π–π stacking between the planar shape-persistent molecules, is conducive to enhancement of the exciton migration along the long axis of nanofibres. Such extended exciton migratio...

A method for simply and controllably modifying the surface of polyaniline nanofibres is described. The technique can be used to attach substituents bearing both acid and amine functional groups, making the materials suitable for further modification. Acid/amine functionalisation is achieved by a simple reflux reaction and therefore is a quick and easily scalable process. The modified nanofibres...

By acetylene pyrolysis at 650 and 5508C, carbon nanotubes were synthesized successfully in porous alumina templates anodized in sulfuric and/or oxalic acid solution. For templates anodized in oxalic acid followed by boiling in distilled water, thermal decomposition of acetylene at 6508C in the pores results in the formation of carbon nanofibres. For templates anodized in sulfuric acid, only car...

The dynamic behaviour of supramolecular systems is an important dimension of their potential functions. Here, we report on the use of stochastic optical reconstruction microscopy to study the molecular exchange of peptide amphiphile nanofibres, supramolecular systems known to have important biomedical functions. Solutions of nanofibres labelled with different dyes (Cy3 and Cy5) were mixed, and ...

Self-assembly of small molecules in water to form nanofibres, besides generating sophisticated biomaterials, promises a simple system inside cells for regulating cellular processes. But lack of a convenient approach for studying the self-assembly of small molecules inside cells hinders the development of such systems. Here we report a method to image enzyme-triggered self-assembly of small mole...
