Most of us benefit from some sort of combustion every day. Whether for the release of heat or the expansion of gas to perform work, this special category of oxidation is probably the most widely-used chemical reaction in our daily lives.

Liquid Wood: The Renewable, Carbon-Neutral Fuel Alternative That Is Finally Ready to Burn
Discussions of sustainable energy don’t often include food flavorings. However, the same process that creates liquid smoke—the stuff you can buy at the grocery store to add a smoky flavor to just about anything—can produce liquid wood, a very environmentally friendly fuel.

What is SCADA?
SCADA stands for Supervisory Control and Data Acquisition system. It is a type of industrial control system (ICS), which is basically a computer system designed to monitor industrial processes in the real world. But unlike other industrial control systems, SCADA systems can compute multiple sets of data over long distances. The primary benefit of a SCADA system is the ability to see a visual representation of […]
