Quasi-superplasticity in an Mg–Li–Al–Y alloy processed by rolling by Furong Cao, Bijin Zhou, Panning Xu, Guangming Xu

“…The microstructural evolution, mechanical properties, model, and deformation mechanism under hot tension were studied by optical microscope, X-ray diffraction, scanning electron microscope, energy dispersive spectroscopy, and tensile tester. Mechanical properties tests showed that the maximum elongation of 265.8% was achieved at 623 K and 5.0 × 10−4 s−1 Microstructural examination found that the tensile alloy is composed of α-Mg + β–Li dual-phase banded grains under high strain rate condition, which disappears when the strain rate decreases and the temperature increases. …”

Spore-Derived Isolates from a Single Basidiocarp of Bioluminescent <i>Omphalotus olivascens</i> Reveal Multifaceted Phenotypic and Physiological Variations by Rudy Diaz, David Bermudes

“…Radial growth rates fell into at least five distinct categories, with only slower-growing isolates obtained compared with the parental dikaryon. Scanning UV-vis spectroscopy of liquid-grown cultures showed variation in pigmentation in both the absorption intensity and peak absorption wavelengths, indicating that some isolates vary from the parental strain in both pigment concentration and composition. …”
