Effects of expanded graphite's structural and elemental characteristics on its oil and heavy metal sorption properties.

Expanded graphite has promising potential environmental applications due to its porous structure and oleophilic nature, which allow it to absorb large quantities of oil. The material is produced by intercalating graphite and applying heat to convert the intercalant into gas to cause expansion between the layers in the graphite. Using different intercalants and temperature conditions results in varying properties of expanded graphite.

Influence of Nanoparticles on Thermal and Electrical Conductivity of Composites.

This review analyzes thermal and electrically conductive properties of composites and how they can be influenced by the addition of special nanoparticles. Composite functional characteristics-such as thermal and electrical conductivity, phase changes, dimensional stability, magnetization, and modulus increase-are tuned by selecting suitable nanoparticle filler material. The conductivity of composites can be related to the formation of conductive pathways as nanofiller materials form connections in the bulk of a composite matrix.
