3D printing with a bite

Dentistry is a new frontier for the application of additive manufacturing or 3D printing. The technology is able to produce components with complex geometry, such as those evident in dental frameworks. Find out how it was introduced in the traditional, artisan-based industry of dental laboratories.

Detecting landmines for a safer world

While the use of landmines has reduced over the last 20 years, they are still present in many countries as the result of actions such as civil wars and insurgencies. Cost-effectiveness and the appropriate technology are key to aid in humanitarian demining.

Graphene's material promise

Just one atom thick but stronger than diamond, graphene’s mix of mechanical and electrical properties have proposed it as the answer to many questions. Where do graphene's strengths lie in industry and where does it fall down?

Birds flying in a V formation

Migratory birds such as ducks and geese fly in a symmetric V-shaped flight pattern, known (not unexpectedly) as a V formation. The reasons for this follow from the applications of aeronautics, fluid dynamics and energy minimisation.

Should we trust connected devices?

Domestic applications of the Internet of Things (IoT) can yield myriad benefits, but they also bring risks. Paul Taylor FREng, Partner, Risk Consulting, at KPMG LLP, asks whether these risks should make us question whether we should trust the devices that connect our homes to the internet.

Processing the plastic problem

Plastic waste is an increasing global problem. While efforts are being made to encourage recycling and less usage, plastics – especially those that are hard to recycle – are still causing pollution. Recycling Technologies is using a chemical process to create a high-value product from plastic waste.
