Laundry capsules that contain single doses of detergent and take up less space than conventional detergents are set to make a comeback. That’s the topic of an article in the current edition of Chemical & Engineering News (C&EN), weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.
C&EN Assistant Managing Editor Michael McCoy explains that the technology behind films used to package the single doses of detergent have come a long way in the five decades since their debut. Previous versions of the encapsulating films interacted poorly with the detergent and had short shelf-lives. And another type of single-dose formulation — essentially a tablet of compressed laundry powders — didn’t dissolve fully, leaving partially consumed chunks among the clean clothes.
In recent years, single-dose liquids packaged in polyvinyl alcohol film have caught on in the U.K. and France. The German company Henkel now has plans to market a similar “mono-dose” in the U.S. in the coming weeks, and Procter & Gamble plan to launch “Tide Pods” within a month. The same dose is used regardless of the amount of laundry that needs to be washed. Although the main technical challenges have been solved, experts say that “the jury is still out” on whether consumers are ready for these products.

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...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
