A filter for environmental remediation

A team of researchers at Osaka University has developed a nanopowder shaped like seaweed for a water filter to help remove toxic metal ions. Made of layered sodium titanate, the randomly oriented nanofibers increase the efficacy ...

The surprising strength of liquid crystals

Dendrites are the destructive by-products of the cycle of charging and discharging lithium ion batteries. These tiny deposits form between the battery's anode and cathode, building up over time. Inevitably, they diminish ...

Oxygen can do a favor to synthesize metal-organic frameworks

Metal-organic frameworks, or MOFs, are composed of metal ions periodically surrounded by organic bridging molecules, and these hybrid crystalline frameworks feature a cage-like hollow structure. This unique structure motif ...

Metal-ion breakthrough leads to new biomaterials

Metals such as iron and calcium play a crucial role inside the human body, so it's no surprise that bioengineers would like to integrate them into the soft, stretchy materials used to repair skin, blood vessels, lungs and ...

The key to lowering carbon dioxide emissions is made of metal

Carbon dioxide (CO2) levels are rising and our planet is heating up. What do we do? What if we used this excess CO2 as a raw material to produce things we need—similar to how plants use it to produce oxygen.

Splitting water molecules for a renewable energy future

The future economy based on renewable and sustainable energy sources might utilize battery-powered cars, large-scale solar and wind farms, and energy reserves stored in batteries and chemical fuels. Although there are examples ...

Metal organic frameworks made to act as liquids

Innovative materials called metal organic frameworks (MOFs) could become much more versatile following research that shows that they can be manipulated as liquids.
