The massive Wolf-Rayet Binary LSS1964 (=WR29), II: the V light curve [PDF]

, 2009
Context. WR 29 is a known WN7h+O double-lined binary system with a rather short period (3.164 days). Aims. We search for light variations to determine the inclination of the system and thus the absolute masses of both components. Methods.

Biodegradable Biocomposites of Isosorbide‐Plasticized Corn Starch Reinforced With Green Graphene: Enhanced Properties for Sustainable Applications

Polymer Composites, EarlyView.
Different properties of biocomposites based on TPS with isosorbide as a plasticizer and green graphene filler. ABSTRACT New biocomposites of corn starch plasticized with isosorbide and filled with two types of “green” graphene with different oxygen content, 1% (G99) and 8% (G92), were processed by melt blending.
