Like most high school students, I didn’t know what career I wanted to pursue. A group of senior mining engineering students pointed me into the right direction. They told me: “If you like to play with big machines and to blow up stuff legally, then go into mining engineering.”
Computer chips and electronic circuitry made from diamonds? Sounds like just bling, but nanodiamond-based components for microelectronic devices not only are very robust; they’re inexpensive.
Developed by researchers at Vanderbilt University, the devices are made by depositing a thin nanodiamond film on a layer of silicon dioxide and then vacuum-packaging it.
What do the blockbuster movie Avatar, high-performance sports gear, the Angry Birds phone app, and pollution-eating bacteria have in common? They are among a host of fascinating innovations developed by engineers and featured in the newest edition of the American Society for Engineering Education’s (ASEE) Engineering, Go For It magazine.

Carlos Barrios, the thirteenth miner to be freed, emerges from the capsule
On August 5, 2010, the San José copper-gold mine near Copiapó, Chile collapsed, leaving 33 men trapped over 2,000 feet below ground.
Sixty-nine days later (a record period of time for surviving underground), all 33 of the miners were rescued.
The miners spent 17 days underground before making contact with the outside world. But once they did, engineers had to race to devise an escape shaft that could reach so deep underground – and safely, without harming the men trapped below. In the mean time, teams of rescue specialists worked to make sure the miners stayed healthy and fed.
The Jwaneng diamond mine in Botswana is the richest diamond mine in the world, producing roughly 14 million carats of diamond a year.
When deepening excavations revealed a harder geological ore body at the Jwaneng mine, more powerful crushers were requested to reduce large rocks into smaller ones and differentiate the diamonds from other raw materials such as rock ore.
