Cornell researchers have harnessed a chemical reaction typically used in rocket fuel ignition to create a ... forming carbon tubes with a unique abundance of five-membered carbon rings, unlike ...

We are fascinated by the hybrid rocket engine which [Ben Krasnow] built and tested in his shop. It is actually using a hollow cylinder of acrylic as the fuel, with gaseous oxygen as an oxidizer.

When it doesn't, well, it is still a tube of explosive material ... The SpaceX Falcon 9's Merlin engines use rocket-grade kerosene (RP-1) fuel with liquid oxygen as the oxidizer.

The trials verify that the fuel can survive the harsh environment of a nuclear rocket reactor. Up until now, the main way of propelling spacecraft has been through chemical rockets. To be fair ...
