The Presence of Two Distinct Red Giant Branches in the Globular Cluster NGC 1851

, 2009
There is a growing body of evidence for the presence of multiple stellar populations in some globular clusters, including NGC 1851. For most of these peculiar globular clusters, however, the evidence for the multiple red giant-branches (RGBs) having ...

Hollow Cholesteric Liquid Crystal Elastomer Fiber with Synergistically Enhanced Resilience and Mechanochromic Sensitivity

Advanced Science, EarlyView.
It describes hollow cholesteric liquid crystal elastomer fiber with radial helix prepared by solvent evaporation‐induced assembly and template assistance. The fiber show mechanochromic wavelength blueshift of 2.25 nm·%−1 under low strain. Excellent mechanochromic reversibility and resilience are devoted by cross‐linking in the wall layer.
