Why dragon's breath? “When you eat it, you will smoke like a dragon,” reads the vendor's sign. While the dessert sounds cool, the liquid nitrogen used can be as cold as negative 320 degrees.

A Cryo-Refrigerator, mounted on the built-in dewar, then liquefies the Nitrogen gas. Step 3: Storing and Dispensing Liquid Nitrogen The liquefied Nitrogen drops into a built-in certified dewar for a ...

Scientists in China have simulated a system that combines liquid-based direct air capture with diabatic compressed air energy storage, for the benefit of both processes. Exploring its economic ...

I AM much puzzled by some recent results as to the density of nitrogen, and shall be obliged if any of your chemical readers can offer suggestions as to the cause. According to two methods of ...

One of Roger Ruan’s liquid nitrogen generator prototypes. “The main idea is simply to use air, water and electricity to produce nitrate, ” said Ruan, a professor at the University of Minnesota.

There were definitely some limitations too. The relatively low yield of just 130cc per hour and high 1400W power draw make this more of a novelty than an efficient liquid nitrogen generator.
