Lotus Glass Repels Water, Dirt, Bacteria

first_imgImagine never having to wash your windows again.  That would be a huge boon not only for window washers on skyscrapers, but for astronauts on the space shuttle or space station.  It may become a reality, thanks to the lotus plant.    Science Daily reported on work by a company in Atlanta that has developed a transparent coating for glass that renders it impervious to dirt and water.  The secret: imitating the surface of a lotus leaf, which “contains innumerable tiny spikes that greatly reduce the area on which water and dirt can attach.”  NASA’s Goddard Space Flight Center is taking a keen interest in this technology, because it can “prevent dirt from accumulating on the surfaces of spacesuits, scientific instruments, robotic rovers, solar array panels and other hardware used to gather scientific data or carry out exploratory activities on other objects in the solar system.”  The latest work seeks to manufacture the material such that it can withstand the harsh space environment.    For us earthlings, the applications of lotus-leaf surface coatings to everyday objects – eyeglasses, windshields, camera lenses and windows – promises a low-maintenance, clear view through the looking glass.  And there’s an extra benefit.  The material also repels bacteria.  Think of how hospitals could stay more hygienic with lotus-like surfaces on walls, windows and equipment.    For previous stories on the properties of the lotus leaf, see 10/17/2006, 01/18/2005 and 10/27/2004.This all began when someone looked at lotus leaves in the rain and noticed how the water beads up and runs off, leaving a clean surface.  Look around at nature and notice what other technologies have already been designed and could be applied to human needs. (You may want to get an early start if you manufacture windshield wipers.)  There’s a bright future in biomimetics, no thanks to Darwin. (Visited 16 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

From Pretoria to Durban, the country became a hive of excitement in anticipation of the tournament.“[The excitement] is about South Africa and we’re taking it to the world,” musician Brian Temba, who was based in the UK until 2009, said from stage. A number of musicians, including Khanyo Maphumulo, Lulu Dikana, Camagwini, Watershed and many others, brought the stage alive to encapsulate the excitement of South Africans for the long-awaited event.“What an amazing day. It is 100 days to go. We will have an incredible event in South Africa,” said Lupi Ngcayisa, a producer at local radio station Metro fm.Ngcayisa, who runs a charitable campaign supplying underprivileged children with new school shoes, brought the message home to fellow South Africans that their visitors will expect nothing but ubuntu when they arrive in June. “It is up to us to ensure that the people who come here are treated with the utmost respect.”Sorina “The Flooze” Erasmus from popular local soapie 7de Laan was one of the stars of the event and got everyone hyped up about the Diski Dance, a dance style she, like many other South Africans, seems to have perfected.The City of Johannesburg used the day to send a message to the world that it’s ready to welcome them. Johannesburg is the only city in the country that will host matches in two stadiums, Ellis Park and Soccer City, and will stage 15 games including the opening match, a semi-final and the final.City employee Smokey de Clown, as he identified himself, could have easily won a prize for best dressed South African on the day. With a painted face and a strange outfit, designed from his work uniform, De Clown was a real clown, but he had an important message for tourists: “We want to show the world that Joburg is ready. Bring the world cup to Joburg.”Thanks for Football FridaysDavid Mabu is one of those colourful football fanatics who never misses a Bafana Bafana game. Mabu, a staunch Kaizer Chiefs supporter, was visibly excited as he moved and swayed with the singing crowd. “I’m the happiest fan… I’m even happy that South Africans are starting to get excited.“We’re the luckiest generation. This did not happen in our fathers’ time, but it’s happening in 2010,” said Mabu.He’s grateful for Football Fridays, the campaign spearheaded by the International Marketing Council that urges people to wear a football jersey every Friday until the World Cup kicks off. “I’m impressed by whoever created the Football Fridays concept. People are starting to buy Bafana jerseys, that will inspire the team.”Encouraging Bafana BafanaNobody doubts that the nation will get behind Bafana. The vuvuzela has become an unstoppable phenomenon and it will be blaring in support of the team. The nation will sing songs of support and the world will know that “Africa’s time has come, Ke Nako” indeed, as a local slogan goes.“We should encourage Bafana Bafana in whatever way we can,” said Benedict Majatladi from Alexandra.“We know what Bafana needs, they need power. The power inside of you can do wonders,” said singer Lulu Dikana, exhorting the national squad.The main event marking the 100 days remaining to the first match, which sees South Africa and Mexico face off, took place in Durban. Deputy President Kgalema Motlanthe, Fifa President Sepp Blatter and about 120 local and international journalists were in attendance.“South Africans are excited for a good reason,” President Jacob Zuma said at an event in the UK. “The World Cup provides an excellent opportunity to promote our country as a place of dynamism, growth and opportunity.”last_img read more
