Muscovite mica sheets with a thickness of 12m were irradiated by various kinds of swift heavy ions in Heavy Ion Research Facility in Lanzhou(HIRFL).In the irradiation experiment,the fluence was kept in the range of 1×10^(10)∼1×10^(12) ions/cm^(2),whereas the electronic stopping power Se was in the range from 5.9 to 31.5 keV/*** vibrational modifications in irradiated mica were investigated by Fourier-transform infrared(FTIR)spectroscopy and the morphology of the nano-defects on the surface of mica was analyzed by the atomic force microscopy(AFM)in the tapping *** infrared spectrum showed that motions from all atomic types in the muscovite mica structure could be found in modes for all *** intensity of all observed vibrational modes,including the O-H stretching motion at 3621 cm^(−1),was found to decrease with increasing Se values and ion *** was indicated that formation of the defects and structural modifications take place in muscovite mica as a result of swift heavy ion *** it was found that more defects were introduced in mica by irradiation with higher ion fluences and higher electronic stopping power Se values.

InP crystals and GaN films were irradiated by 86Kr and 209Bi ions of initial kinetic energy 25 and 9.5 MeV/u, respectively. The ion fluence ranging from 51010 to 3.61012 ions/cm2 was applied. The thicknesses of the InP and the GaN films were 500 and 30 m, respectively. After irradiation, Raman spectra were measured using 532 nm laser as an excitation source in backscattering geometry.

Biological ion channels possess a remarkable ability to selectively modulate ionic flux and play an irreplaceable role in many life processes^([1]).The modulation of ion transport through nanopores or nanochannels has received considerable attention due to the similar transport mechanism of biological ion *** has become the most promising membrane material because of its good permeability,mechanical strength and chemical stability.
