Scientists create diamonds at room temperature in minutes – New Orleans, Louisiana

Diamonds may exist forever, but that doesn’t mean they need to take years to form. Gemstones are usually created after carbon has been crushed and heated well below the surface of the earth for billions of years. Australian scientists say the process was speeded up in just a few minutes and at room temperature. An international team of researchers led by the Australian National University (ANU) and RMIT University in Melbourne, Australia said they created two types on Wednesday to 640 African elephants balancing at the tip of ballet shoes. Use the equivalent pressure to produce diamonds at room temperature. Researchers said they were able to create two types of structurally different diamonds. One is similar to what is normally worn in jewelry, and the other is another type. Called lonsdaleite, it is found naturally in the impact of meteorites and is harder than most diamonds. Synthetic diamonds themselves are not new, they have already been created. d Since the 1940s, we have been researching in the lab to find cheaper, ethical and environmentally friendly stones. However, researchers were excited to create harder lonsdaleite diamonds that could be used to cut such diamonds, especially “ultrasound”, at room temperature. “The long-term goal of this work is to create more of this rare but very useful diamond,” said Xingshuo Huang, an ANU scholar working on the project. “It was the first time in our lab to be able to produce two types of diamonds at room temperature and it was exciting.” Diamonds grown in the lab are usually made by exposing carbon to intense heat.

Diamonds are typically formed over billions of years, at a depth of about 93 miles on Earth, with high pressures and high temperatures above 1,000 degrees Celsius (1,832 degrees Fahrenheit), “she said. “The twist of the story is how we put pressure on it.” Dougal McCulloch, a professor of physics at RMIT, who co-leads the study, and his team experiment with advanced electron microscopy techniques. I took slices from the samples and got a better understanding of what they were like. The team examined the sample and found that both regular and Lonsdaleite diamond veins were flowing. “It was great to see these little” rivers “of Lonsdaleite and regular diamonds for the first time and it really helped me understand how they were formed. “McCarlock said researchers at the University of Sydney and Oak Ridge National Laboratory in Tennessee, USA, were also involved in the study.

Diamonds may last forever, but that doesn’t mean they need to take years to form.

Gemstones are usually created after carbon has been crushed and heated well below the surface of the earth for billions of years. That’s why I’m so hungry for gems.

Now, Australian scientists say the process has been sped up in just a few minutes and at room temperature.

An international team of researchers, led by the Australian National University (ANU) and RMIT University in Melbourne, Australia, uses pressure equivalent to 640 African elephants balancing at the tip of ballet shoes to create two types at room temperature. Announced that it has created a diamond. ..

Researchers said they were able to create two types of structurally different diamonds. One is similar to what is normally worn in jewelery, and the other is naturally found at meteorite impacts and is called lonsdaleite, which is harder than most diamonds.

Synthetic diamonds are not new in their own right and have already been created in the lab since the 1940s to find cheaper, ethical and environmentally friendly stones.

However, researchers are excited to create harder Lonsdaleite diamonds that may be used to cut “supersolid” materials at room temperature, especially at mining sites. They said they were.

“The long-term goal of this work is to create more of this rare but very useful diamond,” said Xingshuo Huang, an ANU scholar working on the project. “Being able to make two types of diamonds at room temperature was exciting to achieve for the first time in our lab.”

Lab-grown diamonds are usually created by exposing carbon to intense heat.

Huge twist, sliding force

Jody Bradby, a professor of physics at ANU, said researchers applied enormous pressure to create “twisting or sliding forces” that caused carbon atoms to move into place to form diamonds. He said he thinks.

“Natural diamonds are typically formed over billions of years at about 93 miles of Earth’s depth, where high pressures and temperatures above 1,000 degrees Celsius (1,832 degrees Fahrenheit) are present,” she said. “The twist of the story is how we put pressure on it.”

Dougal McCulloch, a professor of physics at RMIT, who co-leads the study, and his team used advanced electron microscopy techniques to extract slices from experimental samples to better understand how they were formed. ..

When the team examined the sample, they found that both regular diamond and Lonsdaleite diamond veins were flowing.

“It’s great to see these little” rivers “of Lonsdaleite and regular diamonds for the first time, and it really helps to understand how they are formed,” McCulloch said.

Researchers at the University of Sydney and Oak Ridge National Laboratory in Tennessee, USA, also participated in the study.
