The thermal pyrolysis behaviour of a complex of β-cyclodextrin (CD) and potassium ferrioxalate (PF) was analyzed using gas chromatography coupled to time-of-flight mass spectrometry. Two rare inorganic ions: CO(2)(2+) and O(4)(+), neither of which was found in the cases of free β-CD and PF, were synchronously observed during the decomposition of the complex. Our observations led to proposed formation mechanisms of the ions, in which the structural transformation of a metastable intermediate ion…

Low-temperature carbonization and more effective degradation of carbohydrates induced by ferric trichloride.
The results demonstrated that FeCl(3) played the role of a catalyst during the degradation of the carbohydrates in solution, and a molecule-ion interaction emerged between FeCl (3) and the carbs in aqueous solution, resulting in a more effective degradation ofthe carbohydrates.
Temperature-dependent formation of Ru-based nanocomposites: structures and properties
A new route to produce Ru-based nanocomposites with mixed valence states of ruthenium is reported in this paper via a solid-phase sintering process. Precursor particles were prepared by an intimate
Structure, Property, and Function of Gallium/Urea and Gallium/Polyethylene Glycol Composites and Their Sintering Products: β- and γ-Gallium Oxide Nanocrystals
The first part of the study is devoted to the comparison between the doping effect of urea (a small molecule) and polyethylene glycol (PEG, a long-chain polymer) on the physical property of metallic
Distinctive electronic structure, unusual magnetic properties and large enhancement in SERS of 1D gallium nanoribbons achieved by doping calix[6]arene
The present work provides a novel route for forming one-dimensional (1D) gallium (Ga) nanoribbon materials with a host molecule calix[6]arene (CA-6) as a template by a facile, one-step and low
Creation of hollow microtubular iron oxalate dihydrate induced by a metallo-supramolecular micelle based on the self-assembly of potassium ferrioxalate and sodium dodecyl sulphate
A novel metallo-supramolecular micelle PF–SDS–SM was formed at room temperature through the self-assembly of potassium ferrioxalate and sodium dodecyl sulphate. This leads to a new reaction pattern
Leveling effects of ammonium salts on thermal stabilities of polyethylene glycols.
The interaction between inorganic ions and polymer molecules and the Hofmeister effect of ions in solution are two important factors affecting the stability of salt–polymer composites, because they can contribute to decrease the interaction between the polymer chains, leading to changes in the conformation and pyrolysis mode of polymers.
Formation, structure and thermal properties of the ternary aggregate of polyethylene glycol, β-cyclodextrin and ferrocene
In this study, we firstly describe the formation of a ternary aggregate of ferrocene (Fc), polyethylene glycol (PEG) and β-cyclodextrin (β-CD). Our results provide strong evidence for the fact that


Study of thermal stability of β-cyclodextrin/metal complexes in the aspect of their future applications
The interaction of cyclodextrins with transition metal ions, mostly due to the presence of similar complexes in biological systems. Metal polysaccharide chemistry plays a crucial role in crosslinking
A glycine ruthenium trithiacyclononane complex and its molecular encapsulation using cyclodextrins.
The cytostatic and antiproliferative activity of the complex Ru([9]aneS(3)(gly)Cl and its four CD inclusion compounds was tested on the human osteosarcoma MG-63 cell line and the results compared to the inhibitory effect exerted by the pure cyclodextrins.
Striking structural transformation from cyclic oligosaccharide to aromatic series by means of the effect of lithium carbonate based on gas chromatography coupled to time-of-flight mass spectrometry.
The efficient transformation from a sugar structure to an aromatic structure is ascribed to the contribution of the molecule-ion interaction between beta-CD and Li(2)CO(3) to provide new insight into the link between supramolecular chemistry and other fields such as organic synthesis, biomineralization, environmental protection, and energy utilization.
