Types of back pain Backache is most common in the lower back ('lumbago'), although it can be felt anywhere along your spine, from your neck down to your hips.
Graphene (/ËÉ¡raef.ËÉ¡rÃ¦f/) iËn is an allotrope of carbon in the form of a-two, dimensional-atomic, scale hexagonal lattice in which one atom forms each. Vertex it is the basic structural element of other, allotropes including, graphite, charcoal carbon nanotubes and. fullerenes
Researchers have found yet another use for the wonder material graphene. A composite material made from reduced graphene oxide and magnetite could effectively remove arsenic from drinking water, according to new work done in South Korea. Graphene is a sheet of carbon just one atom thick that also exists as an oxide. Reduced graphene oxide (RGO) is a chemical state of the material that has gained electrons. The purification process works by dispersing a magnetite-RGO composite in water, where it soaks up arsenic. The composite is then quickly and efficiently removed from the water using a permanent magnet.
