Ni(II)-dimethylglyoxime ion-imprinted polymer (Ni(II)-DMG IIP) was encapsulated in polysulphone and electrospun into nanofibres with diameters ranging from 406 to 854 nm. The structures of the Ni(II)-DMG encapsulated-IIP nanofibre, non-imprinted encapsulated-polymer nanofibre and polysulphone nanofibre mats were observed by scanning electron microscopy and evaluated by infrared spectroscopy. El...
A photochromic supramolecular nanofibre, composed of a diarylethene derivative, exhibits hydrodynamic alignment upon exposure to the audible sound. The aligned nanofibre outputs linear dichroism (LD), whose wavelength region can be switched reversibly with UV and visible light.
We study the coupling of spontaneously emitted photons from lasercooled Rb atoms to the guided modes of an optical nanofibre to demonstrate the potential such fibres offer as tools for detecting and manipulating cold atoms, even when the number of atoms is very small. We also demonstrate the integration of an optical nanofibre into an absorption spectroscopy setup, showcasing the ability of the...
We consider two rubidium atoms, prepared in the same S or P Rydberg states near an optical nanofibre. determine van der Waals interaction between them and identify novel features, including reshaping of anisotropy formation potential well nanofibre for states. attribute these phenomena to breaking rotation symmetry around interatomic axis due presence fibre. Our work constitutes important step ...

The growths of oil and gas exploration and production activities have increased environmental problems, such as oil spillage and the resulting pollution. The study of the methods for cleaning up oil spills is a critical issue to protect the environment. Various techniques are available to contain oil spills, but they are typically time consuming, energy inefficient and create secondary pollutio...
Some key parameters of supports such as porosity, pore shape and size are of great importance for fabrication and performance of zeolite membranes. In this study, we fabricated millimetre-thick, self-standing electrospun ceramic nanofibre mats and employed them as a novel support for zeolite membranes. The nanofibre mats were prepared by electrospinning a halloysite nanotubes/polyvinyl pyrrolid...
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...
In this paper, for the first time, polypyrrole-coated electrospun nanofibre mats have been used as separation membranes to electrolessly recover Au from aqueous [Au(III)Cl4] solutions, based on a continuous-flow membrane separation process. With a [Au(III)Cl4] solution passing through the nanofibre membrane, the Au(III) ions were converted into elemental Au. The gold recovered was deposited on ...
The nanocomposite web of calcium alginate and polyvinyl alcohol with varying proportion has been prepared by electrospinning and its application for wound healing is examined. Scanning electron microscope and Fourier transform infrared spectroscopy have been used to characterize the morphology and molecular fingerprint. The water vapour transmission rate of the blended nanofibre composite web h...
