In addition to solar wind pick-up of cometary ions, charge exchange between solar wind ions and cometary neutrals is, potentially, an important comet-solar wind interaction closer to the nucleus. One monitor of the charge exchange rate is the relative abundances of solar wind He 2+ and He ...
Effect of Electric Field on Ion Transport in Nanoporous Membranes with Conductive Surface The effect of an external electric field on the ionic conductivity and selective properties of ceramic membranes based on alumina nanofibers coated with a ... DV Lebedev,VS Solodovnichenko,MM Simunin,... -...
Although there are several examples of ionic liquid gels that exhibit photochromism and photoconductivity, this is the first report of an ionic liquid gel that exhibits both these properties as well as charge accumulation. We conducted experimental and theoretical investigations to understand the ...
of an expansion of a host lattice, which usually gives rise to a decrease of the crystal field splitting and results in the shift of 5d–4f emission towards short wavelengths24. Robbin observed an interesting phenomenon regarding the luminescence of YAG: Ce; i.e., the characteristic absorption...

Lawrence - that’s a great distillation of wisdom for Li-ion batteries. I suggest one addition/update to an otherwise faultless article. The iPad battery is rated at 80% capacity after 1000 charge cycles - whereas the iPhone, as stated above, is rated at 80% after 500 cycles.User...
According to Pauling’s second rule3, the ionic bond strength is related to an ion’s charge divided by its coordination number. The idea was followed inter alias by Brown4, whose method is now widely used in the crystallography of minerals. It relays on correlation of bond distance to bond...
