Abstract: A clathrate of 1-methylcyclopropene with ?-cyclodextrin, obtained as a solid particulate product, is modified by comminuting, classifying, or both to obtain a modified particulate. When subjected to identical atmospheric disgorgement conditions of humidity and temperature, identical masses of the modified and unmodified particulates exhibit different rates of 1-methylcyclopropene disgorgement. Specifically, we have found that a smaller mean particle size is inversely related to a greater rate of 1-methylcyclopropene release.

Abstract: A separation vessel containing a multi-phase mixture comprising oil and water comprises a buoyant thermal energy transfer device. The buoyant thermal energy transfer device further comprises a thermally conductive body and an internal heating element. The buoyant thermal energy transfer device defines a collective specific gravity between about 0.7 and about 1.2, which may be accomplished by adding positioning floats to the buoyant thermal energy transfer device. With such a collective specific gravity, the buoyant thermal energy transfer device is situated in the emulsion layer of the multi-phase mixture, with the internal heating element applying heat to emulsion layer, aiding in the breakage of emulsions. Demulsified oil and water may then be removed from the separation vessel.

Abstract: An adsorbate-selective metal organic framework includes a transition metal; and a plurality of organic molecules coordinated to the transition metal so as to preserve open coordination sites for selectively adsorbing molecules that have low-lying ?* orbitals. The transition metal has a lowest energy spin state in the presence of the selectively adsorbed molecules that are strongly bonding to the transition metal through ?-donating interactions which is different than the lowest energy spin state in the absence of these adsorbed molecules. The transition metal has also a lowest energy spin state in the presence of non-selected molecules that are weakly bonding to the transition metal through ?- and/or ?-accepting and/or donating interactions.
