A revised method to create hydrophobic surfaces has implications for any technology where water meets a solid surface, from optics and microfluidics to cooking.
. The discovery challenges existing ideas about friction between solid surfaces and water and opens up a new avenue for studying droplet slipperiness at the molecular level. The new technique has applications in a range of fields, including plumbing, optics, and the auto and maritime industries.
By carefully adjusting conditions such as temperature and water content inside the reactor, the team could fine-tune how much of the silicon surface the monolayer covered. At low coverage, the water becomes a film over the surface, which had been thought to increase the amount of friction. 'We found that, instead, water flows freely between the molecules of the SAM at low SAM coverage, sliding off the surface. And when the SAM coverage is high, the water stays on top of the SAM and slides off just as easily. It's only in between these two states that water adheres to the SAMs and sticks to the surface.
The research used the national research infrastructure OtaNano was carried out by the Soft Matter and Wetting group at the Department of Applied Physics, which has also produced other pioneering water-repellent materials.Researchers develop a fabrication method to increase the efficacy and longevity of membrane separation technology. The team created a nanofibrous membrane with electrospinning, in which a liquid ...

Researchers correct overestimation by 'hot model' climate projections on warming in ChinaChanges in mean temperature and temperature extremes at regional scale under a warmer climate have received much attention. A subset of CMIP6 climate models, known as 'hot models,' have been projecting more significant warming due to greenhouse gases.
