Festivities at the Delft Innvations Award ceremony<\/p><\/div>\n

TU Delft\u2019s best 24 inventions were presented at the first-ever \u2018Delft Innovation Award\u2019 ceremony, held last Tuesday. Delta presents the winner and two other favourites of the newspaper\u2019s science desk.<\/strong><\/p>\n

And the winner was Professor Bert Wolterbeek, with his entry \u2018Chemical Separation\u2019 \u2013 a procedure that allows a wider range of nuclear reactors to produce medical isotopes. Bob Ursem, director of the botanical garden, received the Demo award, which will allow him to have a 20,000 euros prototype made of his fine-dust reduction system. The public\u2019s favourite was Rolf Hut\u2019s invention, Disdro, a microphone turned into a rain meter.<\/p>\n

TU Delft\u2019s Executive Board initiated the Delft Innovation Award (DIA) in an attempt to make innovations more visible and put researchers in the limelight. \u201cScientific inventions form the link between pure science and ground-breaking innovations that are applicable for economic or societal benefit,\u201d according to a statement on TU Delft\u2019s website. The competition was open to all scientific staff members. On the application form they had to explain the applicability and innovativeness of their submissions. Variable criteria, of which two had to be fulfilled, included sustainability, aesthetics, simplicity and usability. Eight jury members, handpicked for their links to technology and innovation, assessed the submissions, under the jury presidency of Rector Karel Luyben.<\/p>\n

Bert Wolterbeek enables wider production of medical isotopes - TvD<\/p><\/div>\n

Radiodiagnostics<\/strong>
\nEvery now and then news media announce a possible shortage of radioisotopes because one or more of the high flux reactors where medical isotopes are produced has been decommissioned. Currently there are only five reactors worldwide suited for producing 99Molybdeen \u2013 the precursor of 99mTechnetium, which is used for cancer diagnosis. The invention by the faculty of Applied Science\u2019s radiation and isotopes for health section aims to rectify the pending shortages: the new 99Mo production process they developed doesn\u2019t require the high neutron fluxes of special high flux reactors. In fact, more nuclear reactors can be used for the isotope production.<\/p>\n

The key to their innovation is the chemical separation of irradiated 99Mo from the 98Mo target. At first glance this seems impossible, since the capture of a neutron does not change the chemical properties. But Bert Wolterbeek and his team have shown that the recoil energy of the formed 99Mo makes the atom breaks loose from its neighbours, which allows it to be flushed out and collected. So far, up to 25 percent of the activated Mo-atoms have been collected afterwards.
\nFour patents protect the Chemical Separation invention. The team is currently developing technology to scale up the production. The 20,000 euro award will be used in the research. \u201cIt gives us a bit more elbowroom\u201d, says Wolterbeek.<\/p>\n

Rafa Bidarra made virtual worlds affordable - TvD<\/p><\/div>\n

Virtual Creation<\/strong>
\nIt must feel a bit like being the good Lord in the act of Creation: you simply draw a dashed blue line towards the ocean, and a rich meandering river emerges, complete with realistic sandy shores and reed banks. SketchaWorld, a software jointly developed by the computer graphics group at EEMCS and TNO, aims to do for virtual world design what Google\u2019s Sketchup did for 3D modeling: make it accessible to the masses. The user simply defines the type of landscape and adds waterways, vegetation, roads and urban structures at will. The computer keeps track of the structures in several layers, while automatically filling in the details (like a bridge where a road crosses a river) and providing the photorealistic rendering. \u201cCreating such a virtual environment used to require months of digital slavery,\u201d says Dr Rafael Bidarra, only half jokingly. It was that enormous non-creative effort that inspired him four years ago to try and develop software that takes care of the tedious detailing, thus allowing designers to concentrate on the landscape instead of the pixels. \u201cSketchaWorld allows users to concentrate on what they want and forget about the how to make it.\u201d Eventually, the resulting 3D virtual worlds may be exported for use in (serious) games and simulations. Bidarra hopes that a techno-starter will bring the technology to the market.<\/p>\n

Mick Eekhout made the first eco urban villa - TvD<\/p><\/div>\n

Eco-apartments<\/strong>
\nToo much wind last Monday hindered the assembly of the Concept House prototype on the grounds of RDM. But knowing its developer, Professor Mick Eekhout, a new attempt will be made as soon as the weather permits. The Concept House is the result of four years of development between the TU\u2019s faculty of Architecture and a dozen enterprises involved in the building and installation sectors, with each contributing 10,000 euro per year to develop an energy-producing apartment. Other contributors followed, which led to the creation of a budget for building a prototype \u2013 a definitive first in the faculty\u2019s history.<\/p>\n

The Concept House produces energy via PV-panels situated on its roof. Moreover, the house saves energy by recirculation of heat and has been equipped with the most energy-efficient cooling and heating: a heat pump coupled to a deep heat basin. Measuring 7.5 by 15 metres, the apartments are meant for normal families. The wood-framed and tiled \u2018shoe boxes\u2019 may be stacked four stories high in the form of urban villas.<\/p>\n

Eekhout is still looking for a \u2018normal family\u2019 to take up residence at the RDM site. However, such a family shouldn\u2019t mind being studied by industrial design researchers eager to record their energy behaviour.<\/p>\n
