Sending your favorite suit to the dry cleaners could one day become an infrequent practice. Researchers at Clemson University are developing a highly water-repellant coating made of silver nanoparticles that they say can be used to produce suits and other clothing items that offer superior resistance to dirt as well as water and require much less cleaning than conventional fabrics.
The patented coating — a polymer film (polyglycidyl methacrylate) mixed with silver nanoparticles — can be permanently integrated into any common fabric, including silk, polyester and cotton, the researchers say. In the long run, it can save time and money by reducing expensive dry cleaning bills. It is also environmentally friendly, they add.
The researchers described their work on the so-called “self-cleaning” coating last week during the 56th Southeast Regional Meeting of the American Chemical Society, the world’s largest scientific society, held in Research Triangle Park, N.C. “The coating doesn’t actually clean itself, but it does resist dirt much better than other fabric treatments,” explains research team member Phil Brown, Ph.D., a textile chemist with Clemson University in Clemson, S.C. “The concept is based on the lotus plant, whose leaves are well-known for their ability to ‘self-clean’ by repelling water and dirt. Likewise, when water is exposed to the treated fabric, the dirt will be carried away more easily. You will still need some water to rinse away dirt and stains, but cleaning will be quicker and less frequent.”

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
