The Persian Empire (539-330 BCE) was the first world empire in history. At its height, it united a territory stretching from present-day India to Libya - and it would take 2,000 years before significantly larger empires emerged in early modern Eurasia. Its size and power was revered by some, feared…

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

The Wadi al Jizzi Archaeological Project is a systematic and long term archaeological surface survey project, investigating the rich archaeological heritage of the Wadi al Jizzi region (Oman) from the Paleolithic until the early Modern period.
