Normal mode spectrum of the parallel-chain Β-sheet This is paper number 39 in a series on “Vibrational Analysis of Peptides, Polypeptides, and Proteins,” of which paper number 38 is Ref. 19.
(Wiley Subscription Services, Inc., A Wiley Company, 1988-06)
Normal mode calculations have been carried out for parallel-chain Β-sheet structures. These include the parallel-chain pleated sheet of poly( L -alanine) and the parallel-chain rippled sheet of polyglycine. Dipole derivative ...
Supercritical fluid jet expansions of polar aromatic carboxylic acids using simple derivatization with detection by resonant two-photon ionization
(Elsevier, 1988)
In this work simple derivatization is used as a means of enhancing the solubility of polar aromatic carboxylic acids in supercritical CO2 and N2O. The supercritical fluid is then expanded from 200 atm and 40[deg]C through ...
Dynamics of growth of silica particles from ammonia-catalyzed hydrolysis of tetra-ethyl-orthosilicate
(Elsevier, 1988-07)
The NH3-catalyzed formation of colloidal silica particles from tetra-ethyl-orthosilicate (TEOS) in methanol and ethanol is studied by means of light scattering and Raman spectroscopy. We find that the growth is characterized ...
Strain and temperature accelerated relaxation in polycarbonate
(John Wiley & Sons, Inc., 1988-11)
The nonlinear viscoelastic behavior of glassy polymers and its relationship to ductile yielding is studied by single- and double-step stress relaxation experiments. In the latter case a small stress relaxation step is ...
Homogeneous enzyme-linked competitive binding assay for biotin based on the avidin-biotin interaction
(Elsevier, 1988)
A homogeneous enzyme-linked competitive-binding assay for biotin with glucose-6-phosphate dehydrogenase (G6PDH), is described. This assay is based on the interaction between a G6PDH/biotin conjugate with avidin, a natural ...
A total synthesis of the naturally occurring pyrrolo[2,3-]pyrimidine nucleoside, mycalisine A
(Elsevier, 1988)
The first total synthesis of mycalisine A, a pyrrolo[2,3-]pyrimidine nucleoside, was accomplished by a multi-step synthesis from toyocamycin.
Laser-driven micro-explosive bonding of aluminium films to copper and silicon
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1988-06)
Laser explosive microfabrication was used to bond micrometre-thick aluminium films to both copper and silicon substrates. Bonding was observed in both systems for laser intensities greater than about 1 × 10 9 W cm −2 and ...
Observation of coupled quasi-two-dimensional electronic excitations in tilted magnetic fields
(Elsevier, 1988)
We report on a magneto-Raman scattering investigation of free and donor-bound electrons in GaAs/AlxGa1-xAs quantum wells. For fields perpendicular to the layers, the spectra show intersubband transitions of photoexcited ...
