22 Jan 2015 - Golden 'nano-drill'
Spherical gold particles are able to ‘drill’ a nano-diameter tunnel in ceramic material when heated. This is an easy and attractive way to equip chips with nanopores for DNA analysis, for example. Nanotechnologists of the University of Twente published their results in Nano Letters.
22 Jan 2015 - Dutch engineers popular with US companies
Many alumni of the three technical universities (Twente, Delft and Eindhoven) work in the United States. These universities recently began setting up joint local alumni chapters in places such as Boston, New York, Seattle, San Francisco and Houston. With over 3,000 members in the US, the network of these Dutch alumni is very impressive. For example, the worldwide network of Dutch alumni is larger than the alumni network of the prestigious Massachusetts Institute of Technology (MIT).
20 Jan 2015 - FOM Valorisatieprijs uitgereikt
De FOM Valorisatieprijs is op 20 januari uitgereikt aan Dave Blank en Guus Rijnders, van het MESA+ Instituut voor Nanotechnologie van de UT. Zij hebben de prijs ontvangen uit handen van Hans Clevers, voorzitter van de Koninklijke Nederlandse Akademie van Wetenschappen.
14 Jan 2015 - 250,000 euros subsidy for UT spin-off MyLife Technologies
MyLife Technologies BV, a spin-off company of UT research institute MESA+, received a subsidy of 250,000 euros of the ministries of Education, Culture and Science and Economic Affairs, in the form of a loan. The subsidy is intended for converting scientific innovative knowledge into commercial applications. The company develops sticking plasters that have hundreds of tiny needles in them, with which you can painlessly administer vaccines in a completely new fashion.
14 Jan 2015 - Nanoparticles for clean drinking water
One way of removing harmful nitrate from drinking water is to catalyse its conversion to nitrogen. This process suffers from the drawback that it often produces ammonia. By using palladium nanoparticles as a catalyst, and by carefully controlling their size, this drawback can be eliminated. It was research conducted by Yingnan Zhao of the University of Twente’s MESA+ Institute for Nanotechnology that led to this discovery.
12 Jan 2015 - “Upside down, boy you turn me”
Ever since the early 1900s work of Niels Bohr and Hendrik Lorentz, it is known that atoms display characteristic resonant behavior to light. The hallmark of a resonance is its characteristic peak-trough behavior of the refractive index with optical frequency. Scientists from the Dutch MESA+ Institute for Nanotechnology at the University of Twente have recently infiltrated cesium atoms in a self-assembled opal to create a hybrid nanophotonic system. By tuning the opal’s forbidden gap relative to the atomic resonance, dramatic changes are observed in reflectivity. In the most extreme case, the atomic reflection spectrum is turned upside down compared to the traditional case. Since dispersion is crucial in the control of optical signal pulses, the new results offer opportunities for optical information manipulation. As atoms are exquisite storage devices for light quanta, the results open vistas on quantum information processing, as well as on new nanoplasmonics. The results appear in the leading journal Physical Review B that is published by the American Physical Society (APS).
9 Jan 2015 - Publication in Biophysical Journal
This week, Biophysical Journal has published an article by dr.ir. Claas Willem Visser (postdoc at the research group Physics of Fluids) et al., on Quantifying Cell Adhesion through Impingement of a Controlled Microjet. In this work, the shear stress exerted by the jet on the impingement surface in the micrometer-domain has been both modelled and measured, and has subsequently been correlated to jet-induced cell detachment.

6 Jan 2015 - Allard Mosk appointed Fellow of the Optical Society of America
Prof. Allard Mosk from the department of Complex Photonic Systems (COPS) at the MESA+ research institute has been appointed a Fellow of the Optical Society of America (OSA). The appointment is in recognition of Mosk's development of a new approach to the focusing and imaging of light through strongly scattering media, such as paint, paper and biological tissue.
