Abstract: Present embodiments include composite dental materials for use in fillings and crowns, and methods of making the same. The composite materials can include biocompatible dental resin matrices and filler materials. The filler materials can include various types of magnetic nanoparticles. Additional embodiments include method of forming composite dental materials using a magnetic field and methods for forming aluminum oxide (Al2O3) nanoparticles. Other embodiments according to present teachings include methods for filling dental cavities and forming dental crowns.

Abstract: Methods of manufacturing a carbon structure including exposing a carbon fiber substrate to oxygen at a first predetermined temperature and activating the carbon fiber substrate by exposure to oxygen at a second predetermined temperature. A catalyst including palladium is deposited on the activated carbon fiber substrate. The deposited catalyst on the carbon fiber structure is exposed to a hydrocarbon at a third predetermined temperature to grow carbon structures thereon. The carbon structures grown can be multimodal in nature with structures that are nano-scale and/or submicron-scale.

Abstract: According to various embodiments of the present teachings, there is a metal-carbon nanotubes composite and methods of making it. A method of forming a metal-carbon nanotube composite can include providing a plurality of carbon nanotubes and providing a molten metal. The method can also include mixing the plurality of carbon nanotubes with the molten metal to form a mixture of the carbon nanotubes and the molten metal and solidifying the mixture of the carbon nanotubes and the molten metal to form a metal-carbon nanotube composite.
