Functional biogeography may bridge a gap between field-based biodiversity information and satellite-based Earth system studies, thereby supporting conservation plans to protect more species and their contributions to ecosystem functioning. We used airborne laser-guided imaging spectroscopy with environmental modeling to...

Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Oct;60(4):4252-6. doi: 10.1103/physreve.60.4252.

The ordering process and kinetics in thin films (200-800-nm thick) of a thermotropic side-chain liquid-crystalline polymer have been investigated vertically and laterally, respectively, by x-ray reflectivity and atomic-force microscopy. The original smooth and amorphous spin-coated films initially become corrugated...

J Am Chem Soc. 2008 Dec 24;130(51):17552-62. doi: 10.1021/ja8068038.

The nanoporous metal-organic framework, Fe(bpe)2(NCS)2 x 3(acetone), SCOF-4(Ac) (where bpe is 1,2-bis(4'-pyridyl)ethane), displays a two-step spin crossover (SCO) transition (65-155 K) that is sensitive to the presence of acetone guest molecules. Structural analyses have revealed a structural phase transition,...

Angew Chem Int Ed Engl. 2009;48(14):2549-52. doi: 10.1002/anie.200805178.

Bottoms up! A discrete metallo-supramolecular nanoball (see picture), synthesized by using "bottom-up" methodologies, uniquely undergoes a solvent-sensitive, physically addressable electronic spin switching. The switching occurs by thermal, light, or solvent perturbation, where importantly it can be switched "on" or...

PMID: 19916507
J Am Chem Soc. 2009 Dec 09;131(48):17546-7. doi: 10.1021/ja908415z.

The impact of modest, industrially accessible pressures (0-1.2 GPa) on the structure and porosity of the zeolitic imidazolate framework Zn(2-methylimidazole)(2), ZIF-8, was investigated using in situ powder X-ray diffraction in combination with sorption measurements for pressure-treated samples. The framework...
