Perovskite is quickly gaining on silicon in the solar cell field, but it has one major drawback – durability. Now, a new treatment has been shown to keep perovskite solar cells working at 99% of their efficiency after 1,000 hours of use.

While reusing cutlery is always better than discarding it, most people aren't going to be packing a knife and fork whenever they grab some fast food. Scientists have thus designed a plant-and-wood-based material that dissolves once broken apart.

It sounds like a superhero's origin story: scientists have discovered a new type of material created after lightning struck a tree. This particular form of crystalline phosphorus has never been seen on Earth, and could belong to a new mineral group.

Scientists at the University of Rochester claim to have created a material that acts as a superconductor at room temperature and lower pressures than ever before. If confirmed, this “reddmatter,” as they call it, could mark a major breakthrough.

Perovskites are one of the most promising new materials for solar cell technology. Now engineers at the University of Rochester have developed a way to more than triple the material’s efficiency by adding a layer of reflective silver underneath it.

With the world focused on addressing climate change, scientists have had to get creative when it comes to developing sustainable building materials that tackle CO2 emissions. A team has now engineered wood that is stronger and traps carbon dioxide.

Modern concrete starts to fall apart within decades – but ancient Roman structures are still standing strong after 2,000 years. Engineers have found an inclusion that helps ancient concrete self-heal cracks, and shown how we can recreate the recipe.

Scientists at the University of Maryland have developed a novel gel sheet material with excellent absorption abilities, which they imagine finding use everywhere from messy kitchens to operating theaters.

As one of the strongest materials known to science, spider silk regularly finds itself at the center of exciting engineering breakthroughs, but a new study involving a quick chemical bath could see silkworm silk outperform it.

Engineers have developed a new 3D-printed titanium alloy with a unique microstructure that makes it ultra-strong. Not only is it stronger than other forms of titanium, but it has the highest strength-to-weight ratio of any 3D-printed metal ever made.

Old electronics are tricky to recycle, meaning they clog up landfills while locking valuable metals away. Now scientists have demonstrated printed circuits that can be degraded on demand, returning their materials to reusable forms.

We've seen some inventive ideas around how giant turbine blades might be saved from landfill at the end of their lives, and scientists have just thrown another one into the mix with some wide-ranging, and delicious, potential.
