There’s possibly nothing more frightening than struggling to take a breath. Something asthmatics and others with respiratory diseases know all too well. Many of these people depend on portable oxygen concentrators, small … Read more
When it comes to solar panels, the future is flexible. Vanessa Young discovers how a MacDiarmid project is unlocking the possibilities of a new generation of solar cell technology. When we imagine solar panels, we think of hard rectangle frames, sitting upright on roofs, or spread out across expanses of deserts. But imagine flexible, bendy … Read more
