Oct 28, 2020 · A relatively small number of guest molecules with a shorter induction time for pure guest hydrate nucleation can promote the formation of initial nuclei of a mixed hydrate. Detailed cage analysis shows that small guests such as CH 4 can induce the formation of more standard cages for mixture systems with either C 2 H 6 or C 3 H 8 systems ...
Jan 19, 2021 · We demonstrate that the CH 4 –CO 2 guest composition impacts the guest–host interactions in hydrates during static temperature measurements at 10 K, implying that these interactions are ...

Feb 5, 2024 · PDF. Tools. Share. Graphical Abstract. In this study, inclusion crystals composed of a benzophenone-naphthalenediimide host ( 1) and halobenzene guests were developed, unveiling unique fluorescence and room temperature phosphorescence (RTP) properties.
X-ray single crystal analysis revealed a 1: 1 host–guest inclusion complex of the composition [dMV @ CPA5]·5.27(H 2 O) in the P 2 1 / c space group of the monoclinic system. The asymmetric unit comprises one CPA5 molecule, one paraquat cation (modelled as disordered over two positions) included into the host cavity, and water molecules.
Aug 28, 2015 · In the case of clathrate hydrates (often simply referred to as “Hydrates”), the host is composed of hydrogen-bonded water molecules which are arranged in a three-dimensional crystalline lattice. 1 The guests that can be trapped within the water host lattice comprise small molecules, e.g., methane, carbon dioxide, hydrogen.
