Abstract: Embodiments of the present disclosure pertain to methods of sorption of H2O from an environment by associating the environment with a porous material such that the association results in the sorption of H2O to the porous material. The porous material includes a (M)-2,4-pyridinedicarboxylic acid coordination polymer, where M is a divalent metal ion selected from the group consisting of Mn, Fe, Co, Ni, Mg, and combinations thereof. The coordination polymer has a one-dimensional pore structure and shows reversible soft-crystal behavior. The porous material may be a Mg(II) 2,4-pyridinedicarboxylic acid coordination polymer (i.e., Mg-CUK-1). The methods of the present disclosure may also include one or more steps of releasing the sorbed H2O from the porous material and reusing the porous material after the releasing step for sorption of additional H2O from the environment.

Abstract: Disclosed is a method of producing an olefin using a circulating fluidized bed process, including: (a) supplying a hydrocarbon mixture including propane and a dehydrogenation catalyst to a riser which is in a state of a fast fluidization regime, and thus inducing a dehydrogenation reaction; (b) separating an effluent from the dehydrogenation reaction into the catalyst and a propylene mixture; (c) stripping, in which a residual hydrocarbon compound is removed from the catalyst separated in step (b); (d) mixing the catalyst stripped in step (c) with a gas containing oxygen and thus continuously regenerating the catalyst; (e) circulating the catalyst regenerated in step (d) to step (a) and thus resupplying the catalyst to the riser; and (f) cooling, compressing, and separating the propylene mixture, which is a reaction product separated in step (b), and thus producing a propylene product.

Abstract: The present invention relates to a composition for temperature sensors including graphene oxide, DNAzyme and PNA, a temperature sensing method and a kit using the same. In the present invention, when the DNAzyme/PNA duplex is dissociated at a certain temperature, graphene oxide adsorbs PNA with excellent selectivity and irreversibility, enabling recall of temperature, to permit delayed color development in the time of need. Also, the target temperature can be easily and quickly detected with the naked eye through the color change of the colorimetric reagent, and the thermosensor is technically convenient and easy to apply, so it can be used in various biological applications. Moreover, it can be used as a barcode (on/off) system using a combination of PNA probes with various lengths, and thus can be broadly applied to sensing a diverse range of temperatures.
