Spectral energy distributions and colours of hot subluminous stars
Open Astronomy, 2018 Photometric surveys at optical, ultraviolet, and infrared wavelengths provide ever-growing datasets as major surveys proceed. Colour-colour diagrams are useful tools to identify classes of star and provide large samples.

Journal of the Society of Materials Science, Japan, 2006 Equal channel angular pressing (ECAP) invented by Segal was applied successfully to metal process of aluminum and magnesium alloys for increasing their strength by fining the grain size. But a little attention has been paid to its application to polymers.

Enhancing Ductility of ECAP Processed Metals
Materials Science Forum, 2010 Mechanical properties such as hardness, mechanical strength or fatigue resistance are by far the most successful material behaviour improved by the ECAP processed. However, the lack of ductility is the most critical negative effect. Combination of multimodal grain size is one of the most promising solutions to improve the strength/ductility balance ...
