Among specific topics are a far infrared modulating spectropolarimeter, magnetic field morphology studied by multi-scale polarimetry in and around the filamentary dark cloud GF-9, light echo polarization for geometric distance measurement, testing the density of distribution of young circumstellar disks, and simulating polarized light from exoplanets.
CD spectra for the wild type Cry1Ac and mutant toxins, H168Q and H168R, were recorded on a Jasco J-500A spectropolarimeter. Molar ellipticity was calibrated with 26.69 mM d-10-camphorsulfonic acid.
A portable spectropolarimeter for field crop canopies: Distinguishing species and cultivars of fully developed canopies by polarized light.
Paris, June 24 (ANI): Astronomers, using the NARVAL spectropolarimeter of the Bernard-Lyot telescope in France, have obtained the first detection of a magnetic field on the bright star Vega.
We measured circular dichroism spectra, in methanol solution, at room temperature by use of a Jasco model 810 spectropolarimeter. Circular dichroism spectra were expressed by molar ellipticity in units of millidegrees (m[degrees]).
But in June 1990, when Zhang made the peptide and then analyzed its twist with an instrument called a spectropolarimeter, he realized that it looked nothing like a telephone cord.
CD measurements were carried out on a Jasco spectropolarimeter (Model J-815) equipped with a microcomputer.
CD and UV-vis spectra were measured using a Jasco model J-810 spectropolarimeter (Easton, MD, USA).
Optical rotations were obtained on a PerkinElmer 241 Polarimeter (Waltham, MA, USA), and CD measurements were performed with a JASCO J-815 Spectropolarimeter. UV data were measured using a Beckman Coulter DU 800 spectrometer (Tokyo, Japan).
Circular dichroism (CD) measurements were performed on a Jasco J-815 spectropolarimeter (Jasco Corp., Tokyo, Japan), equipped with a PTC-423S/15 Peltier cell holder for temperature control using a 1 mm path length quartz cuvette under constant nitrogen flow.
CD spectra were collected on a Jasco J-715 spectropolarimeter. Near and far UV CD spectra (200-250 nm) were collected with 0.1 and 1mg/mL of the enzyme placed in a path length of 0.1 and 1cm, respectively.
