Carbon Nanoparticles of Varying Shapes as Additives in Mineral Oil Assessment of Comparative Performance Potential.

In this work, carbonaceous nanoparticles (NPs) of varying morphology, viz., multilayer graphene (lamellar, thickness ∼ 3-7 nm), graphite (spherical ∼70 nm), and multi-walled carbon nanotubes (tubular), were selected to explore their tribo-potential in oil under identical operating conditions. A series of nano-oils were prepared using API group III mineral base oil with a dispersant (1%) and selected NPs in incremental concentration (0.

Sternoclavicular Graft Versus Costochondral Graft In Reconstruction of Ankylosed Temporomandibular Joint.

Introduction: The temporo-mandibular joint (TMJ) is a complex anatomical structure that is concerned with mastication, deglutition, and speech. Ankylosis of the TMJ occurs when the condyle gets fused to glenoid fossa by bony or fibrous tissue. It is an incapacitating problem, commonly occurring in children and is usually associated with trauma or infection.
