The team has created a prototype made of eight mm steel tubes and a transducer.
Every year, large amounts of plastic waste are dumped into the oceans. Much of it forms microplastics, which are tiny fragments of barely visible plastic that are roughly five mm in size.menace continues to pollute the oceans and can be toxic to aquatic animals and plants. Therefore, new technological solutions are required to combat the increasing presence of microplastics in the oceans.
“Because acoustic forces can push particles together, I wondered if we could use them to aggregate microplastics in water, making plastic easier to remove,” said Menake Piyasena, the principal investigator of this project, in aMicroplastics naturally scatter in flowing water , but after turning on sound waves, the particles concentrate along the tube’s sides , making them easier to remove.This device is intended to collect microplastics of varying sizes.
The device would cost approximately seven cents to operate for an hour and a half to clean one liter of water. Following these initial experiments, the team plans to test the prototype on a larger scale, focusing on cleaning ocean water.

Pulsing ultrasound waves could someday remove microplastics from waterwaysColorful particles of plastic drift along under the surface of most waterways, from headwater streams to the Arctic Ocean. These barely visible microplastics—less than 5 mm wide—are potentially harmful to aquatic animals and plants, as well as humans. So, researchers are devising ways to remove them and to stop them at their source. Today, a team reports a two-stage device made with steel tubes and pulsing sound waves that removes most of the plastic particles from real water samples.

What do the elements sound like?In chemistry, we have He, Fe and Ca—but what about do, re and mi? Hauntingly beautiful melodies aren't the first things that come to mind when looking at the periodic table of the elements. However, using a technique called data sonification, a recent college graduate has converted the visible light given off by the elements into audio, creating unique, complex sounds for each one. Today, the researcher reports the first step toward an interactive, musical periodic table.
