The hybrid surface combines hydrophobic nanowires and hydrophilic channels to prevent flooding of condensation
Schematic diagram of a 3D hybrid surface showing anti-loading properties by combining SEM images with film width and drop condensation. Credit: National Taiwan University Condensation is important for applications such as power generation, water harvesting, and cooling systems. However, when the surface temperature is much lower than the ambient steam, traditional surfaces suffer from poor performance under high sub-cooling. This…

China’s growing interest in Spanish and culture brings new channels for learning, such as reggaeton translation
Examples of comments on Chinese from one of the non-professional translators in Spanish and responses received from his followers analyzed in the UPF study. Credit: University of Pompeu Fabra – Barcelona A recent study by UPF examines new informal practices among Chinese communities learning Spanish. Hispanic songs, many of them, are translated into Chinese through the country’s main music streaming…

Water filters with nanoscale channels selectively remove stubborn “eternal chemicals”
Credit: Monash University Traditional water filters struggle to remove smaller PFAS molecules, but the new Monash designed filter changes it. Researchers at Monash University have developed water filter membranes that effectively remove small PFA molecules, overcoming the important challenges faced by traditional water filters. The researchers designed beta-cyclodextrin (βCD)-modified graphene oxide (GO-βCD) membranes using nanoscale channels that selectively retain PFA…

Hidden side channels of quantum sources can impair secure communication
Amita Gnanapandithan, a PhD student at the University of Toronto Engineering, demonstrated the existence of a “hidden” side channel in devices that generate photons used in quantum communications using both practical experiments and computer modeling. Credit: University of Toronto Engineering/Tyler Irving A team of researchers at the University of Toronto Engineering discovered a multidimensional side channel hidden in existing quantum…

Quantifying the way rivers bends may identify the origin of channels on other planets.
Credit: Lee Patrick of Pexel Whether it’s a river that blocks the earth, a lava that melts rocks, or water that slices ice, it twists and bends in a similar, reciprocating way. However, a new study led by scientists at the University of Texas at Austin found that the channels carved into the river had curves that were actually cut…
