Can someone explain what they are trying to say with the whole, "room temperature" thing.
>The carbon is then hit with a single laser pulse lasting approximately 200 nanoseconds. During this pulse, the temperature of the carbon is raised to 4,000 Kelvin (or around 3,727 degrees Celsius)
Are they trying to say that they can make diamonds at STP as opposed to creating a controlled environment in a box?
- mkingston 11y agoI guess that's what they're saying. Contrast with: From https://en.wikipedia.org/wiki/Synthetic_diamond https://en.wikipedia.org/wiki/Synthetic_diamond Synthetic diamond is also widely known as HPHT diamond or CVD diamond after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively) And from https://en.wikipedia.org/wiki/Synthetic_diamond#Chemical_vapor_deposition https://en.wikipedia.org/wiki/Synthetic_diamond#Chemical_vap... Unlike HPHT, CVD process does not require high pressures, as the growth typically occurs at pressures under 27 kPa. [...] and optimizing the substrate temperature (about 800 °C)
- such_a_casual 11y agoThank you for the detailed response. As a layman, the article really confused me.
