Selective oxidation of methanol to methyl formate (MF) is one of the most attractive processes to get valuable methanol-downstream products, where the supported Au and Pd catalysts were proved rather effective at low temperature. To search for highly

During the international campaign of June 1991, the active region AR 6659 produced six very large, long-duration flares (X10/12) during its passage across the solar disk. We present the characteristics of four of them (June 4, 6, 9, 15). Precise meas
