Surface micro- and nanobubbles were formed in situ using a conventional scanning electron microscope by radiolysis of water confined liquid cells with electron-transparent windows. The shapes contact angles the bubbles at window corner directly measured microscope. All observed close to 90°, regardless size, indicating that had almost maximized Laplace pressure. Bubble formation far from irradi...

The yields of ionic and excited molecule reactions in y-radiolysis of liquid propane from 35 to -130C have been assessed by isotopic analysis of C3Hs-l-C3Ds+Oz and CH3CD2CH3 -1-02 mixtures. From a comparison with gas phase data the following conclusions are reached for the gas to liquid phase change: (a) the ionic decomposition yield rlecreases by :5 69 %, (b) the net excited molecule decomposi...
