At the Photonics West, the leading international fair for photonics taking place in San Francisco (USA) this week, Nanoscribe GmbH, a spin-off of Karlsruhe Institute of Technology (KIT), presents the world’s fastest 3D printer of micro- and nanostructures. With this printer, smallest three-dimensional objects, often smaller than the diameter of a human hair, can be manufactured with minimum time consumption and maximum resolution. The printer is based on a novel laser lithography method.
“The success of Nanoscribe is an example of KIT’s excellent entrepreneurial culture and confirms our strategy of specifically supporting spin-offs. In this way, research results are transferred rapidly and sustainably to the market,” says Dr. Peter Fritz, KIT Vice President for Research and Innovation. In early 2008, Nanoscribe was founded as the first spin-off of KIT and has since established itself as the world’s market and technology leader in the area of 3D laser lithography.
PureMadi, a nonprofit University of Virginia organization, will introduce a new invention – a simple ceramic water purification tablet – during its one-year celebration event Friday from 7 to 11 p.m. at Alumni Hall.
Called MadiDrop, the tablet – developed and extensively tested at U.Va. – is a small ceramic disk impregnated with silver or copper nanoparticles. It can repeatedly disinfect water for up to six months simply by resting in a vessel where water is poured. It is being developed for use in communities in South Africa that have little or no access to clean water.
“Madi” is the Tshivenda South African word for water. PureMadi brings together U.Va. professors and students to improve water quality, human health, local enterprise and quality of life in the developing world. The organization includes students and faculty members from engineering, architecture, medicine, nursing, business, commerce, economics, anthropology and foreign affairs.
During the past year, PureMadi has established a water filter factory in Limpopo province, South Africa, employing local workers. The factory produced several hundred flowerpot-like water filters, according to James Smith, a U.Va. civil and environmental engineer who co-leads the project with Dr. Rebecca Dillingham, director of U.Va.’s Center for Global Health.
