We have studied the quantitative structure-property relationship between descriptors representing the molecular structure and glass transition temperature (T(g)) for 103 molecules including organic electroluminescent (EL) devices materials. Eighty-six descriptors were introduced and among them seven descriptors (one topological descriptor, one thermodynamic(More)
Measurements of aerosols were made in 2001 and 2002 at Dunhuang (40 degrees 00'N, 94 degrees 30'E), China to understand the nature of atmospheric particles over the desert areas in the Asian continent. Balloon-borne measurements with an optical particle counter suggested that particle size and concentration had noticeable peaks in super micron size range(More)
