Dear all: I want to calculate the C-C bond energy of diamond and the dangling bond energy on diamond surface by DFT. How can I do? Can you tell me ? Thanks a lot! H. L. Yu :confused:

Wow, one of the main malls in the capital of my country had an "accident". http://www.dominicantoday.com/app/article.aspx?id=14731" Most of the pictures are here http://www.clavedigital.com/afuera/Portadas/EDiamond/Galeria.htm"

A very intelligent, humorous, wise and handsome guy with a degree in anything (preferably not physics and art), who would buy me this http://www.ashford.com/product/index.asp?sn=458045054&md_id=1&pf_id=40646&dept_id=60&comp=Y on Valentine's day! :blushing: Intelligent: IQ > 150 Handsome...

I have searched the web top to bottem for any articles on Pyrolytic Diamond, I am starting to believe that nobody has thought of doing such a material Experiment. There are tons of articles on Pyrolytic Graphite but none of Pyrolytic Diamond. I am aware that Pyrolytic Graphite Levitates on...

Why can't stuff like this ever happen to me? :frown: "An anonymous gift-giver left a $15,000 diamond engagement ring to the owner of an unlocked car in western Massachusetts with a typed note hinting at a broken heart. "Merry Christmas. Thank you for leaving your car door unlocked...

Does anybody know much about, or know where I could find out about, diamond colloid? It is the most energy dense chemical fuel, correct? And if that is true, that would mean it can react to expend the most energy per ounce of any chemical reaction, right?

Lets create a pseudo team of engineers for the purpose of producing the latest advancement in Diamond Evacuated Bubbles, Our team is trying to win a pseudo X-prize, The pseudo prize consists of many millions of pseudo dollars and a lifetime pseudo contract with NASA for the production of the...

Diamond has a tetrahdral shape stucture, an allotrope of carbon with each carbon covalently bonded to 4 others. But what happens at the end Carbon of a diamond?

Validity of hydrogen model for Diamond semiconductors Hi I've calculated the shallow impurity binding energy for diamond for an experiment I'm doing.. I'm just wondering how valid is hydrogen model for this? We assume that the free electron and donar nucleus can be modeled as a...

Hi. I need some help. A baseball diamond is a 90 foot square. A player approaches 3rd base at a rate of 28 feet per second at the instant he is 30 feet from 3rd base. Find the rate of change of the player's distance from homeplate. So df/dt= 28 But I don't know where to go from here.

Can lightning break diamond..? :redface:

I just viewed a news episode concerning synthetic and natural diamonds. Scientifically, there is no difference. But, according to a certain man (whose name escapes me) who examines the clarity of natural diamonds and makes sure they're ready for sale..., there is a difference--an emotional one...

I see in an article on computers that because of faster operating speeds and more transistors per chip, the heat generated will be too much for silicon processors to handle thus a need for something that will and they believe man-made diamond based computer chips are the answer. Is this the...

I have a couple of questions that I need help with. I tried doing the first one but don't know if it is correct. Should the second one be done the same as the first? 1. What is the speed of light in diamond if the index of refraction is 2.42? n=c/v v=3*10^8/2.42 = 1.23*10^8 m/s 2.Given...

Why can't we manufacture 'diamond'?
