Ever since the discovery of fullerenes, towards the end of the last century, a number of new findings about these molecules is afoot. With its unique chemical and physical properties, the applications and uses of these molecules may be infinite.
Acids and Bases - Definition, Examples, Properties, Uses Definition of Acid The term acid and base have been defined in different ways depending on the particular way of looking at the properties of acidity and basicity. Arrhenius first defined acids as compounds which ionize to produce hydrogen ions, and bases

Graphene and fullerenes - Properties of materials - OCR Properties of materials Carbon atoms can form four covalent bonds. This lets it form many different organic substances, and to exist as diamond, graphite and fullerenes.
Undetectable by the human eye, nanoparticles can exhibit significantly different physical and chemical properties to their larger material counterparts. The definition given by the European Commission states that the particle size of at least half of the particles in the number size distribution must measure 100 nm or below.

Encyclopædia Britannica, Inc. Coal, petroleum, natural gas, and oil shale are mainly compounds of carbon and hydrogen derived from plant and animal sources deposited in the Earth millions of years ago and subjected to high pressure. These deposits were once a part of what is called the carbon cycle, a dynamic system of change still occurring.Through photosynthesis, plants use sunlight to
carbon nanotube Properties & Uses BritannicaA SWNT can be described as a long tube formed by wrapping a single graphene sheet into a cylinder with diameter of about 1 nanometer, the ends of which are capped by fullerene cages. The fullerene structures, with alternating structures of five hexagons adjacent to one pentagon, form the surface with desired curvature to enclose the volume. The sidewalls of carbon nanotubes are made of
chemical element - Kids Britannica Kids Homework HelpA chemical element is a basic substance. It cannot be broken down into simpler substances. Chemical elements are the building blocks for all matter that is, everything that takes up space in the universe. They are sometimes just called elements.
These properties and others highlight graphenes tremendous potential for a vast range of applications, from energy to biomedicine to electronics. Graphene is the parent form of the carbon allotropes graphite, composed of stacked layers of graphene, and the fullerenes, hollow molecules made of graphene. The fullerenes include buckyballs
methane Definition, Properties, Uses, & Facts BritannicaMethane, colorless, odorless gas that occurs abundantly in nature and as a product of certain human activities. Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases.
rhodium Definition, Properties, Uses, & Facts BritannicaRhodium, chemical element, one of the platinum metals of Groups 810 (VIIIb), Periods 5 and 6, of the periodic table, predominantly used as an alloying agent to harden platinum. Rhodium is a precious, silver-white metal, with a high reflectivity for light.
Soil is a mixture of minerals and organic material that covers much of Earths surface. Minerals are bits of rock , and organic material is the remains of living things that have died. Soil is not as solid as rock. It has many small spaces, called pores, that hold water and air. In some places on Earth, a Fullerene - Carbon nanotubes BritannicaClosed fullerene structures, incorporating sulfides of such metals as tungsten and molybdenum, exhibit excellent solid-lubricant properties. Conducting carbon nanotubes may be coated with sheaths of metal sulfides to produce tiny insulated electrical wire.
