Core–shell Gd2O3-Coated B4C–Al composites with simultaneously enhanced neutron capture and thermal conductivity

Materials Research Letters
Core–shell boron carbide (B4C) particles coated with ∼100 nm gadolinium oxide (Gd2O3) were synthesized via a metal–organic framework route. Aluminum (Al) matrix composites reinforced with uncoated B4C, Gd2O3, or core–shell B4C@Gd2O3 were comparatively ...

Self-standing and high-performance B4C/Sn/acetylene black@reduced graphene oxide films as sodium-ion half/full battery anodes

, 2021
Sn-based materials show great potentials as sodium-ion battery (SIB) anodes. However, limited to the preparation process and expensive raw materials, it is a great challenge to large-scale produce self-standing Sn-based materials.
