First underwater carpet cloak realized with metamaterial

Researchers at the Institute of Acoustics (IOA) of the Chinese Academy of Sciences have designed and fabricated an underwater acoustic carpet cloak using transformation acoustics, a scientific first. The research was published ...

New measurement technique finds harmful PFAS in indoor air

The air we breathe in our homes, schools, and workplaces can be polluted with harmful PFAS chemicals, according to a study published today in Environmental Science & Technology Letters. A new measurement technique developed ...

Closing the carpet production cycle

Current trends show worldwide demand for carpet rising five percent annually, with production projected to reach 18.6 billion square meters per year by 2016. Good environmental performance and sustainability are now key priorities ...

Polypropylene recycling from carpet waste

A significant part of carpet waste consists of petroleum-based polypropylene. As a non-recyclable product, disposing of it has previously meant incineration or landfill. However, a new solvent is now making it possible to ...

Researchers give unstable soils a carpeting

A new, more environmentally-friendly practice for soil strengthening, using recycled carpet, could see the construction industry substantially decrease its carbon footprint thanks to research from the UTS Centre for Built ...

Acoustics researchers develop novel underwater carpet cloak

Acoustic camouflage, realized by controlling wave propagation, has attracted much attention in recent years. Aided by a reflecting surface, acoustic carpet cloak has become one of the most practically feasible invisibility ...
