    • 摘要: In this review,the application of light ion irradiation is discussed for tailoring novel functional materials and for improving the performance in SiC or Si based electrical power devices.The deep traps and electronic disorder produced by light ion irradiation can modify the electrical,magnetic,and optical properties of films(e.g.,dilute ferromagnetic semiconductors and topological materials).Additionally,benefiting from the high reproducibility,precise manipulation of functional depth and density of defects,as well as the flexible patternability,the helium or proton ion irradiation has been successfully employed in improving the dynamic performance of SiC and Si based PiN diode power devices by reducing their majority carrier lifetime,although the static performance is sacrificed due to deep level traps.Such a trade-off has been regarded as the key point to compromise the static and dynamic performances of power devices.As a result,herein the light ion irradiation is highlighted in both exploring new physics and optimizing the performance in functional materials and electrical devices.

    • 摘要: Different preparation routes for TiO_(2)-supported natural and synthetic clinoptilolite(TiO_(2)/CP)composites were thoroughly investigated on the basis of sol-gel,hydrothermal,and in-situ hydrothermal methods.The micro-structural features and physicochemical properties of resultant TiO_(2)/CPs were characterized via X-ray diffraction patterns,scanning(transmission)electron microscope images,Fourier transform infrared spectra,inductively coupled plasma-optical emission spectrometry methods,BET-isotherms,UV-visible spectra,and surface charge potential distributions.The results showed that in-situ hydrothermal method led to well dispersions of loaded-TiO_(2) particles on the surface of leaf-like CP,while obviously aggregated TiO_(2) on a relatively distorted structure of CP was obtained using sol-gel and hydrothermal methods.Their adsorptive and photocatalytic efficiencies for removal of crystal violet(CV)dye in aqueous solution were also explored under UV-irradiations.The results demonstrated that TiO_(2)/CPs synthesized via sol-gel and in-situ hydrothermal methods presented the excellent performances with 98% removal efficiencies as compare to the bare commercial TiO_(2) which achieved 53%removal of CV dye.While,the in-situ hydrothermally synthesized TiO_(2)/CPs were the best due to their moderate energy cost,highest adsorption capacities and removal efficiencies.Particularly,the synthetic CPs as supports exhibited synergetic photocatalytic activities for the degradation of CV dye,which is attributed to their high surface areas,better adsorption capability,and fine dispersion of TiO_(2) particles.Adsorption and degradation kinetics of CV dye were found to follow the pseudo-second and pseudo-first order models,respectively.

    • 摘要: Phosphate material LiMnPO4 is popular for its high energy density(697 W·h·kg^(-1))and safety.When LiMnPO_(4) crystal grows,the potential barrier along b and c axis is strong,which makes the crystal grow along b axis to form a one-dimensional chain structure.However,the main migration channel of lithium ions in olivine structure is plane(010).By shortening the growth in the direction of b axis and enhancing the diffusion along the directions of a and c,two-dimensional nanosheets that are more conducive to the migration of lithium ions are formed.The dosage of polyols is the key factor guiding the dispersion of the crystals to the(010)plane.X-ray diffraction(XRD),Scanning electron microscopy(SEM),transmission electron microscopy(TEM)and other means are used to characterize the samples.After experiments,we found that when the ratio of polyol/water was 2:1,the morphology of the synthesized sample was 20–30 nm thick nanosheets,which had the best electrochemical performance.At 0.1C,the discharge specific capacity reaches 148.9 mA·h·g^(-1),still reaches 144.3 mA·h·g^(-1) at the 50th cycle.and there is still 112.5 mA·h·g^(-1) under high rate(5C).This is thanks to the good dispersion of the material in the direction of the crystal plane(010).This can solve the problem of low conductivity and ionic mobility of phosphate materials.
