Scientists created spheres of titanium dioxide petals destroy bisphenol A
08 October 2018 Current Affairs:

Scientists at Rice University in the U.S. have created tiny spheres that can catch and destroy BisPhenol A (BPA). The micron-sized spheres are a collection of titanium dioxide petals

BPA is a synthetic chemical used to make plastics that often contaminates water. It is commonly used to coat the insides of food cans, bottle tops and water supply lines. BPA is hydrophobic and naturally attracted to the cavity. Once trapped, Reactive Oxygen Species (ROS) produced by the spheres degrades BPA into harmless chemicals. 

The researchers determined that 200 mg of the spheres per litre of contaminated water degraded 90% of BPA in an hour, a process that would take more than twice as long with unenhanced titanium dioxide.
