using lasers to create super-hydrophobic materials
Bookmarked 574 weeks ago scientists at the university of rochester have used lasers to transform metals into extremely water repellent or super-hydrophobic materials without the need for temporary coatings super-hydrophobic materials are desirable for a number of applications such as rust prevention anti-icing or even in sanitation uses however as rochesters chunlei guo explains most current hydrophobic materials rely on chemical coatings in a paper http:scitationaiporgcontentaipjournaljap117310106314905616 published today in journal of applied physics guo and his colleague at the universitys institute of optics anatoliy vorobyev describe a powerful and precise laser-patterning technique that creates an intricate pattern of micro- and nanoscale structures to give the metals their new properties this work builds on earlier research by the team in which they used a similar laser-patterning technique that turned metals black http:wwwrochesteredunewsshowphpid=2701 guo states that using this technique they can create multifunctional surfaces that are not only super-hydrophobic but also highly-absorbent opticallyguo adds that one of the big advantages of his teams process is that the structures created by our laser on the metals are intrinsically part of the material surface that means they wont rub off and it is these patterns that make the metals repel waterthe material is so strongly water-repellent the water actually gets bounced off then it lands on the surface again gets bounced off again and then it will just roll off from the surface said guo professor of optics at the university of rochester that whole process takes less than a second the materials guo has created are much more slippery than teflona common hydrophobic material that often coats nonstick frying pans unlike guos laser-treated metals the teflon kitchen tools are not super-hydrophobic the difference is that to make water to roll-off a teflon coated material you need to tilt the surface to nearly a 70-degree angle before the water begins to slide off you can make water roll off guos metals by tilting them less than five degreesas the water bounces off the super-hydrophobic surfaces it also collects dust particles and takes them along for the ride to test this self-cleaning property guo and his team took ordinary dust from a vacuum cleaner and dumped it onto the treated surface roughly half of the dust particles were removed with just three drops of water it took only a dozen drops to leave the surface spotless better yet it remains completely dry guo is excited by potential applications of super-hydrophobic materials in developing countries it is this potential that has piqued the interest of the bill and melinda gates foundation which has supported the work in these regions collecting rain water is vital and using super-hydrophobic materials could increase the efficiency without the need to use large funnels with high-pitched angles to prevent water from sticking to the surface says guo a second application could be creating latrines that are cleaner and healthier to uselatrines are a challenge to keep clean in places with little water by incorporating super-hydrophobic materials a latrine could remain clean without the need for water flushing but challenges still remain to be addressed before these applications can become a reality guo states it currently takes an hour to pattern a 1 inch by 1 inch metal sample and scaling up this process would be necessary before it can be deployed in developing countries the researchers are also looking into ways of applying the technique to other non-metal materials guo and vorobyev use extremely powerful but ultra-short laser pulses to change the surface of the metals a femtosecond laser pulse lasts on the order of a quadrillionth of a second but reaches a peak power equivalent to that of the entire power grid of north america during its short burstguo is keen to stress that this same technique can give rise to multifunctional metals metals are naturally excellent reflectors of light thats why they appear to have a shiny luster turning them black can therefore make them very efficient at absorbing light the combination of light-absorbing properties with making metals water repellent could lead to more efficient solar absorbers solar absorbers that dont rust and do not need much cleaningguos team had previously blasted materials with the lasers and turned them hydrophilic meaning they attract water in fact the materials were so hydrophilic that putting them in contact with a drop of water made water run uphill http:wwwrochesteredunewsshowphpid=3387help us caption ampamp translate this videohttp:amaraorgvga08 |

aquatop display
Bookmarked 648 weeks ago aquatop display is a projection system that uses white water as a screen surface this system allows the user039s limbs to freely move through under and over the projection surface using the unique characteristics of fluid we propose new interactions methods specific to the projection medium water our system uses a depth camera to detect input on and over the water surface to allow for interactions such as protruding fingers out from under the water surface and scooping up the water with both hands this type of interaction is not capable with current impenetrable rigid body flat surfaces for example by floating one039s limbs on the water surface it is also possible to fuse one039s body with the displayed objects for further augmented interaction by 039becoming one039 with the screen |
