(4Z)-4-[(2,6-Diisopropyl­anilino)(phen­yl)methyl­idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one

In the title compound, C29H31N3O, the three terminal benzene rings are oriented at dihedral angles of 20.7 (3), 65.8 (3) and 72.6 (3)° with respect to the central pyrazolone ring. Intra­molecular N—H⋯O hydrogen bonding occurs between the imine and carbonyl groups. Inter­molecular C—H⋯π inter­actions are present in the crystal structure

Realizing the Value of Mobile Services in the Exhibition Industry – The Verification of Limit-to-Value Framework

The MICE industry and the M-Commerce service recently become a popular issue since the mature internet environment. It will be a significant subject to realize the IT investment in the MICE industry. The study is to test and verify the Limits to Value for IT Investments framework [1] and to redefine and modify the constructs of model to examine the barriers of IT value, in the context of M-Commerce in the MICE industry. This reforming model can help us understand the critical value discounting factors and the impact about adoption and usage of the innovative IT in the marketplace

Collimated directional emission from a peanut-shaped microresonator

Collimated directional emission is essentially required an asymmetric resonant cavity. In this paper, we theoretically investigate a type of peanut-shaped microcavity which can support highly directional emission with the emission divergence as small as 2.5o. The mechanism of the collimated emission is explained with the short-term ray trajectory and the intuitive lens model in detail. Wave simulation also confirms these results. This extremely narrow divergence of the emission holds a great potential in highly collimated lasing from on-chip microcavities
