Recent Advances in Industrial Coarse-Grained Method Development & Modeling

Fraaije J.G.E.M., Handgraaf J.-W., Culgi, NL

In present day the crux of performing coarse-grained simulations is the actual parameterization of the (molecular) interactions and the validation of the outcome of a simulation. In a recent effort we have work on the [...]

Wafer level integration of epitaxial piezoelectric thin films for novel NEMS, MEMS and MOEMS applications

Dekkers M., Solmates BV, NL

It is well known that Pulsed Laser Deposition (PLD) is a very flexible and versatile technique allowing fast optimization of new and complex material thin films. The unique features of PLD allow for the integration [...]

Development of alumina/iron oxide nanocomposites as adsorbents for arsenic and fluoride removal from aqueous solutions: Process Optimization

Kennedy M., Kumar Sharma S., Prathna T.C., UNESCO-IHE, NL

The study was designed to optimize the process for the synthesis of alumina/ iron oxide nanocomposites and to investigate their potential as a sorbent to remove fluoride and arsenic from contaminated water. The nanocomposites had [...]

Scalable Production of Stabilized Catalysts via Atomic Layer Deposition

Dokania A., Goulas A., Grillo F., van Limpt B., van Ommen R., Delft IMP, NL

We report the use of several nanostructuring concepts using Atomic Layer Deposition (ALD) that coupled with porosity induction via heat treatment resulted to controllably accessible model catalysts. This enables more active, selective and stable catalysts. [...]

Directional wetting on chemically stripe-patterned surfaces

Jansen H.P., Kooij E.S., Zandvliet H.J.W., Univ. Twente, MESA+ Inst. Nanotechnology, NL

The ability to control liquids at surfaces is highly relevant for many application areas, including for example the performance and reliability of inkjet nozzles. Generally, the wettability of solid substrates can be modified both by [...]

Innovative gold nanoparticle patterning and selective metallization

Kooij E.S., Poelsema B., Raza M.A., Zandvliet H.J.W., Univ. of Twente, MESA+ Inst. Nanotechnology, NL

In this contribution we present a novel, simple, low-cost bottom-up method to enable patterned deposition of nanoparticles. Our approach does not require sophisticated equipment nor does it involve harsh chemical procedures. We show that pure [...]

RF-noise modeling in MOSFETs: excess noise, symmetry, and causality

Juge A., Klaassen D.B.M., Pijper R.M.T., Scheer P., Scholten A.J., Smit G.D.J., Tiemeijer L.F., van der Toorn R., NXP Semiconductors, NL

Modeling of RF-noise in MOSFET channels is one of the cornerstones for RF-CMOS-circuit design. Deep sub-micron technology nodes necessitate a proper treatment of excess noise as well as detailed modeling of parasitics. In addition, demanding [...]

Noble metal nanoparticles for plasmonic photothermal therapy of atherosclerosis

Gabinsky J., Kharlamov A., Erasmus University Medical Center, NL

Background: Our previous bench studies PLASMONICS and NANOM First-in-Man trial documented TAV reduction up to unprecedented 79.4 and 60.3 mm3 respectively with high level of safety and feasibility. Methods: The completed randomized two arm (1:1) [...]

Purification of EBID structures of noble metals by electron beam post-irradiation under oxygen flux

Mehendale S., Mulders J.J.L., Trompenaars P.H.F., FEI Electron Optics, NL

Although Electron Beam Induced Deposition (EBID) is considered as a single-step process for creation of three-dimensional nanostructures of different materials, direct deposition of highly pure metallic structures had been rarely achieved. Typically, use precursors such [...]

Hydrogel-based multi-stimuli responsive cilia

An H., Glazer P.J., Lemay S.G., Leuven J., Mendes E., Delft University of Technology, NL

We present large-scale multi-responsive cilia arrays that can be stimulated environmentally (via a pH change), electrically or magnetically. By means of micro-fabrication techniques, we created high-aspect ratio molds on which the polymer solution was cast. [...]
