This essential oil has been used for almost 100 years in Australia but is now available worldwide both as neat oil and as an active component in an array of products. The primary uses of tea tree oil have historically capitalized on the antiseptic and anti-inflammatory actions of the oil.
A computer graph is a graph in which every two distinct vertices are joined by exactly one edge. The complete graph with n vertices is denoted by Kn. The following are the examples of complete graphs. The graph Kn is regular of degree n-1, and therefore has 1/2n(n-1) edges, by consequence 3 of the handshaking lemma.
Researchers from Zhejiang university in Hangzhou, China, showed off their newly developed graphene aerogel by balancing a block of the stuff on a delicate cherry blossom. The sponge-like matter is made of freeze-dried carbon and graphene oxide and is the lightest solid material in the world. Chinese researchers showed off their graphene aerogel by balancing it on the petals of a cherry blossom. 2  The sponge-like matter is made of freeze-dried carbon and graphene oxide and is the lightest material ever made. 3  Graphene was developed nine years ago by two Russian researchers working at Manchester University.
