Advertising is commonly presented in the context of media articles or programs that are intended to engage the consumer. An important aspect of this engagement is media transportation, where a person not only attends to information but also is absorbed into the narrative flow of a story in a pleasurable and active way. This research examines the effects of the transportation experience produced by the media context on the impact of ads that appear in that context. Three studies show that transportation can have both positive and negative effects on advertising. Intrusion of the ad into the transportation process is shown to mediate the negative effects, which occurs independently of involvement.
CO2 hydrogenation to ethanol is of practical
importance
but poses a significant challenge due to the need of forming one C–C
bond while keeping one C–O bond intact. CuI centers
could selectively catalyze CO2-to-ethanol conversion, but
the CuI catalytic sites were unstable under reaction conditions.
Here we report the use of low-intensity light to generate CuI species in the cavities of a metal–organic framework (MOF)
for catalytic CO2 hydrogenation to ethanol. X-ray photoelectron
and transient absorption spectroscopies indicate the generation of
CuI species via single-electron transfer from photoexcited
[Ru(bpy)3]2+-based ligands on the MOF to CuII centers in the cavities and from Cu0 centers
to the photoexcited [Ru(bpy)3]2+-based ligands.
Upon light activation, this Cu–Ru–MOF hybrid selectively
hydrogenates CO2 to EtOH with an activity of 9650 μmol
gCu
–1 h–1 under 2 MPa
of H2/CO2 = 3:1 at 150 °C. Low-intensity
light thus generates and stabilizes CuI species for sustained
EtOH production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
