The observations of the exceptionally bright gamma-ray burst (GRB) 130427A by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope provide constraints on the nature of these unique astrophysical sources. GRB 130427A had the largest fluence, highest-energy photon...

Flexibility and color monitoring of cellulose nanocrystal iridescent solid films using anionic or neutral polymers.

ACS applied materials & interfaces

Bardet R, Belgacem N, Bras J.
PMID: 25552332
ACS Appl Mater Interfaces. 2015 Feb 25;7(7):4010-8. doi: 10.1021/am506786t. Epub 2015 Feb 17.

One property of sulfated cellulose nanocrystals (CNCs) is their ability to self-assemble from a concentrated suspension under specific drying conditions into an iridescent film. Such colored films are very brittle, which makes them difficult to handle or integrate within...

PMID: 12437764
BMC Anesthesiol. 2002 Nov 01;2:6. doi: 10.1186/1471-2253-2-6.

BACKGROUND: A recent article in the New Scientist argued that women were under-represented in clinical trials which, until now, had masked the finding that ibuprofen 400 mg was ineffective in women.METHODS: Meta-analysis of randomised, double-blind placebo-controlled trials of ibuprofen...

PMID: 18259224
Appl Opt. 1997 Jul 01;36(19):4367-81. doi: 10.1364/ao.36.004367.

Third-generation synchrotron radiation light sources provide partially coherent radiation. Certain topics in the optical design of beam lines and monochromators can be studied with electric-field distributions only rather than with intensity distributions of the light source. The radiation characteristics...
