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 ...

Modified 'white graphene' for eco-friendly energy

Scientists from Tomsk Polytechnic University (TPU), together with colleagues from the United States and Germany, have found a way to obtain inexpensive catalysts from hexagonal boron nitride or "white graphene." The technology ...

Researchers simplify tiny structures' construction drip by drip

Popping the top on house paint usually draws people to look inside the can. But Princeton researchers have turned their gaze upward, to the underside of the lid, where it turns out that pattern of droplets could inspire new ...

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 ...

Engineers give invisibility cloaks a slimmer design

Researchers have developed a new design for a cloaking device that overcomes some of the limitations of existing "invisibility cloaks." In a new study, electrical engineers at the University of California, San Diego have ...

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 ...

Seafloor carpet catches waves to generate energy

(Phys.org) —What do champion surfers who gathered at last week's Mavericks Invitational have in common with a UC Berkeley engineer? They all are looking to harness the power of big ocean waves.
