Nanodots From Pencil Leads

If you want to improve the efficiency of solar cells, use your pencil. Well, the graphite in pencils can now be used to make tiny nanodots. Graphite rods in sodium hydroxide solution produce nanodots which can potentially be used to augment existing solar panels.
Nanodots from pencil leads
The Pencil study involved using pencil "leads" as the cathode and anode, which were dropped into ethanolic sodium hydroxide. Nano particles of 3 nanometers (nm) were produced. Nanodots in a compound with carboxyl and hydroxyl collected on the anode. The nanodots were then drawn into the pores of a titanium and silicon dioxide template.

Other mesoporous materials have been tested. They each have particular properties in regard to sensing, catalysis and optoelectronics. This allows for fine tuning of solar panels. The pencil lead system improved current transfer from simulated sunlight by 38 per cent.

Anthropology Has New Theory on Australian Aboriginals

New theory on Australian Aboriginals - Anthropology. Australian Aboriginals split from Eurasians and moved south into the dry continent. Twenty thousand years later the world warmed up and Australia was cut off from its northern neighbors. This is the latest theory.  But when Europeans initially came to Queensland there were two types of native people. Each was a distinct genetic pool. One was like Papua New Guineans. The other was very slight and shorter. It is the latter that predominates today. Papua New Guineans Australian Aboriginals Some scientists still hold that there was only one move out of Africa. This is an unsustainable supposition. The doors for movement were always open. Australian Aboriginals were quite unique. It seems that they were the first to leave Africa. There is also the question of Tasmanian Aboriginals who were wiped out by arriving Europeans. There is no evidence of them now. They could not light fires. The flames had to be stol...

Beatboxing - Percussion Sounds of the Mouth

There must be a dearth of things to study. Scientists are now researching the odd sounds that people make. It may seem weird but its true. Those who can make odd sounds are called beatboxers. Scientists are interested in percussion sounds. These are expressed in Celtic, Chinese, North American and Indian cultures. Hip-hop is an area of great interest. A young "practitioner" had MRI scans done on his mouth while he created percussion sounds. The conclusion reached is that a lot of brainpower is involved in imitating percussion. It "is a small part of the larger puzzle," experts say. In my view it takes little mental concentration. Just put your tongue behind you top teeth a "tap" away. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml http://www.technorati.com/blogs/ . . . . . . . . . . . . . . . . . . . .
