Andre Konstantin Geim is the one one that ever gained each a Nobel and an Ig Nobel. He was once born in 1958 in Russia, and is a Dutch-British physicist with German, Polish, Jewish and Ukrainian roots. “Having lived and worked in several European countries, I consider myself European. I don’t believe that any further taxonomy is necessary,” he says. He is now a physics professor on the University of Manchester. He additionally is hooked up as professor by way of particular appointment in cutting edge fabrics and nanoscience on the Radboud University Nijmegen within the Netherlands.
He shared the Noble Prize in 2010 with Konstantin Novoselov for their paintings on graphene. It was once following on their isolation of microscope visual grapheme flakes that the global research in opposition to practical applications of graphene took off. “We did not invent graphene,” Geim says, “we best noticed what was once laid up for 5 hundred yr underneath our noses.”
Geim and Novoselov are steadily concept to have succeeded in isolating graphene from graphite by way of peeling it off with bizarre duct tape till there best remained a layer. Graphene may then be seen with a microscope, as a result of the partial transparency of the fabric. That is, after dissolving the duct tape subject material in acetone, in fact. That could also be the tale Geim himself likes to inform.
However, he didn’t use – because the city fantasy is going – graphite from a commonplace pencil. Instead, he used a carbon pattern of utmost purity, specifically imported. He extensively utilized ultrasound ways. But, almost definitely the city legend will continue to exist, as did Archimedes’ tub and Newtons apple. “It is nice to keep some of the magic,” is the expression Geim steadily makes use of when he does now not desire a great tale to be drowned in arduous info or when he needs to stay discrete about nonetheless incomplete, however promising research effects.
Because of its chemical construction, graphene is a wonderful conductor: carbon has a valence of 4, however within the graphene construction best 3 electrons are sure, the fourth is unfastened. Potential brief to medium time period practical applications vary from new era sun cells to biosensors in addition to new era pc chips, unbreakable house crafts and feather weight bullet evidence jackets.
Geim expects practical applications of those fabrics will seem quickly after the research effects are printed. “In the past, it took forty years before new discoveries lead tot consumption market products. For graphene applications, only ten years passed.”
Geim is already having a look in a extra far away long run. He thinks that almost definitely, a lot more fabrics exist, that during buildings with just one layer of atoms have sudden houses. “I don’t believe this is only the case for carbon varieties, but also for other elements of the periodic system and even for complex molecules. I suggest we should look again at mica,” Geim tells youris.com. His more moderen research comes to graphene-based membranes. For a while, he isn’t satisfied anymore that graphene membranes exceed very a lot the prestations of present membranes in for example desalination of water. However, he needs to determine what reasons that water is in a position to go graphene membranes, whilst it’s unimaginable for different liquids.
Geim underlines the significance of pondering ‘out of the field’ and ‘trial and mistake’ experiments. This manner isn’t just a connection with his mechanical graphene peeling, but additionally to his Ig Nobel paintings. The Ig Nobel Prizes are given for strange or trivial clinical research achievements making other people chuckle, ahead of they lead them to suppose. Geim received this prize along with Mike Berry, for the levitation of a bit of frog in a powerful magnetic box. “First we used a hamster. After we saw the hamster didn’t like it, we took a frog.” Whether the frog favored the experiment, Geim does now not know. The hamster, dubbed H.A.M.S. ter Tisha, was once rewarded with a co-authorship of the research paper. The frog nonetheless stays nameless.
