The single crystals of soluble pigment precursors were obtained. Upon simple thermal annealing, the t -Boc groups were removed and the soluble pigment precursor molecules with latent hydrogen bonding ...

Chemistry students partner with artist to recreate pigment patented by George Washington Carver UChicago students, Amanda Williams revive 100-year-old recipe for startling blue color ...

Considering the 18 cases of postnatal diagnosis of trisomy 7 reported in the literature, 16 were mosaic and 9 of them presented with pigmentary mosaicism. 4 Extracutaneous findings in trisomy 7 ...

Fiber lasers mode locked with large normal group-velocity dispersion have recently achieved femtosecond pulse durations with energies and peak powers at least an order of magnitude greater than those ...

We investigate the dielectric dispersion of water, specially in the low-frequency range, by using the impedance spectroscopy technique. The frequency dependencies of the real R and imaginary χ parts ...

At a prehistoric pigment mine, researchers glimpse our earliest moments in the Americas Derived from iron-rich rocks, red ochre is humanity’s oldest known pigment, with a discovery in a cave in Zambia ...

In this article, we reported a critical improvement on the measurement method for the dielectric dispersion characteristics of hydrate-bearing sediment in a frequency range between 1 MHz and 3 GHz, ...
