Binary Companions of Evolved Stars in APOGEE DR14: Search Method and Catalog of ∼5000 Companions
Abstract Multi-epoch radial velocity measurements of stars can be used to identify stellar, substellar, and planetary-mass companions. Even a small number of observation epochs ...
Covalent Organic Frameworks: Design, Synthesis, and Functions
Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with permanent porosity and highly ordered structures. Unlike other polymers, a significant...
Transfer of Large-Area Graphene Films for High-Performance Transparent Conductive Electrodes
Graphene, a two-dimensional monolayer of sp(2)-bonded carbon atoms, has been attracting great interest due to its unique transport properties. One of the promising applications ...
