The MACS experiment performed at PSI in the 1990s provided an yet unchallenged upper bound on probability for a spontaneous conversion of muonium atom, { M=}({\mu^+e^-}) M=(μ</mml:mi...

steam reforming integrated with oxidation of methanol was considered with numerical simulation. the parallel micro-channels with circular cross sections were used. because when the catalytic deposited inside the rectangular micro-channels, it fills up the edges. hence, the approximation of a cylindrical channel is appropriate. effect of this changing in cross section was considered and results ...
