A study of a C Α, Β -didehydroalanine homo-oligopeptide series in the solid-state by 13 C cross-polarization magic angle spinning NMR
(John Wiley & Sons, Ltd., 2004-06)
The fully extended peptide conformation (2.0 5 -helix) has been investigated for the first time in the solid-state by 13 C cross-polarization magic angle spinning NMR. The compounds examined are members of a terminally ...
Potentiometric ion- and bio-selective electrodes based on asymmetric cellulose acetate membranes
(Elsevier, 1989)
The potentiometric response properties of ammonium-, carbonate-, and proton-selective electrodes prepared by incorporating appropriate neutral carriers within novel asymmetric cellulose acetate membranes are reported. The ...
Electron diffraction study of the molecular structure of bis(trifluoromethyl)peroxide
(Elsevier, 1977-07)
The following structural parameters and estimated standard deviations (3[sigma]) have been found for (CF3O)2,: rg, (O-O) = 1.419 +/- 0.020 A, rg (C-O) = 1.399 +/- 0.009 A, rg (C-F) = 1.320 +/- 0.003 A, [angle](C-O-O) = ...
Phonon Raman spectra, molecular motions, and phase transitions of dimethylacetylene crystal
(Elsevier, 1973-07-15)
The phonon Raman spectra of crystals of dimethylacetylene, perdeutero-dimethylacetylene and their mixtures have been investigated down to 20[deg]K. The high temperature phase shows only one line and the low temperature ...

Hydrazine adsorption and decomposition on the GaAs(100)-c(8 x 2) surface
(Elsevier, 1994-12-20)
Temperature programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS), and high resolution electron energy loss spectroscopy (HREELS) have been used to study the decomposition mechanism of hydrazine (N2H4) on the ...
Non-biomimetic route to deoxyadenosine adducts of carcinogenic polycyclic aromatic hydrocarbons
(Elsevier, 1991-10-21)
Aminotriols are prepared by direct aminolysis of the diol epoxides of polycyclic aromatic hydrocarbons, providing a substantial improvement over literature methods. The condensation of aminotriols with 6-halopurine ...
Proteomic analysis of cold adaptation in a Siberian permafrost bacterium – Exiguobacterium sibiricum 255–15 by two-dimensional liquid separation coupled with mass spectrometry
(WILEY-VCH Verlag, 2006-10)
Bacterial cold adaptation in Exiguobacterium sibiricum 255–15 was studied on a proteomic scale using a 2-D liquid phase separation coupled with MS technology. Whole-cell lysates of E. sibiricum 255–15 grown at 4°C and ...
The microwave spectrum of argon-phosphorus trifluoride
(Elsevier, 1987-01-23)
The argon-PF3 complex has been prepared in a supersonic expansion of Ar (98%) and PF3 (2%). A Fourier-transform micro-wave spectrometer employing a Fabry-Perot cavity was used to assign 28 rotational transitions. The ...
