Floral Scent Variation in Cyrtorchis letouzeyi (Orchidaceae) Between Natural Versus Cultivated Environments

open access: yesBiotropica, Volume 57, Issue 3, May 2025.
Shade houses serve as effective scientific tools for ex situ cultivation and orchid conservation in tropical forests. A comparison of the floral scent chemistry of Cyrtorchis letouzeyi between shade houses and natural populations in Cameroon revealed the same dominant compound, identical qualitative compositions across sites, but variations in emission

Spectral Evidence For A Directional Molecular Rotation In Intermolecular Hydrogen Bonded Liquids

open access: yes, 2015
Vapour and liquid phase infrared spectra of ethanol, 2,2,2-trifluoroethanol, isopropanol and 1,1,1,3,3,3,-hexafluoro-2-propanol were studied. A narrower width is found for several specific ro-vibrational bands in liquid spectra as compared to those of ...

Connecting micelles by metallo-supramolecular interactions: towards stimuli responsive hierarchical materials

open access: yes, 2009
A novel strategy to link block copolymer micelles via metal-ligand interactions, leading to hierarchical supramolecular networks is presented. The mechanical properties of the obtained materials can be tuned easily by the choice of the metal ions used ...
