Metamaterial prism creates a reverse rainbow

(Phys.org)—In a normal rainbow, red is always on "top" while violet is on the "bottom." This is true whether the rainbow is created by a glass prism or by water droplets in the sky, and is due to the way that these materials ...

Cleaning desal plants with mathematics

A Curtin University engineering team has used a mathematical formula to help develop a system which could minimise down time and save on maintenance costs for desalination plants.

Shaking the topological cocktail of success

Graphene is the miracle material of the future. Consisting of a single layer of carbon atoms arranged in a honeycomb lattice, the material is extremely stable, flexible, highly conductive and of particular interest for electronic ...

Powdered milk is a vital ingredient in infant formula and also used in a wide a range of baked goods and confectionary products. It is manufactured using an energy-intensive process chain that involves concentrating and drying ...

Study shows forward osmosis desalination not energy efficient

In a recent study published in the Journal of Membrane Science, MIT professor John Lienhard and postdoc Ronan McGovern, both of the Department of Mechanical Engineering, reported that, contrary to popular support, forward ...

How plants may be evolving to the lack of bees

Plants which used to have two types of male reproductive organs – to increase their chances for fertilisation – are reverting back to one type. And in some cases, they are becoming self-fertilising.
