Combined Ramp and Squeeze at the Large Hadron Collider

In the first two years of operation of the CERN Large Hadron Collider (LHC), the betatron squeeze has been carried out at constant flat top energy of 3.5 TeV. Squeeze setting functions are separated from the energy ramp functions. This ensured a maximum fl ...

Biomimetic soft lithography on curved nanostructured surfaces

Jürgen Brugger, Thomas Kiefer, Valentin Flauraud, Vaida Auzelyte

In this paper a nano-molding process using a nature-created master is demonstrated. The eye of night moth Agotis Exclamationis having 100 nm-scale structures on a curved surface is used as biomimetic master mold from which nanostructures are replicated ont ...

Numerical analysis of zeptogram/Hz-level mass responsivity for in-plane resonant nano-electro-mechanical sensors

Mihai Adrian Ionescu, Dimitrios Tsamados

This paper presents numerical analysis of an in-plane resonant nano-electro-mechanical (NEM) sensor based on mass-detection principle using a 3D FEM electromechanical simulation combined with a NEM/MOS hybrid circuit simulation. The self-assembled linker m ...

Correlation between anionic substitution and structural properties in AlCr(OxN1-x) coatings deposited by lateral rotating cathode arc PVD

Alireza Karimi, Hossein Najafi

The influence of oxygen content on the properties of cathodic arc-deposited AlCr(OxN1-x) coatings has been studied. All samples were prepared in a nitrogen-rich mixture of N-2 and O-2 at 550 degrees C using lateral rotating arc cathodes (LARC) technology t ...

Nanocomposite Coatings for Solar Energy Conversion: Large Opportunities for Small Structures

Andreas Schueler

Due to their fascinating optical and electronical properties, nanometer-scaled structures play an important role in solar energy conversion [1]. Nanocomposite coatings consist typically of dielectric, semiconducting or metallic nanocrystals embedded in a h ...

Development of MEMS Programmable Diffraction Gratings for Spectroscopic Applications in the Visible, Near- and Mid-Infrared

Robert Andrew Lockhart

This work presents the development of two MEMS programmable diffraction gratings designed for spectroscopic applications in the visible, near- and mid-infrared. These devices have been developed to limit distortion of their optical surfaces at rest and thr ...

Plasma Spray-CVD: A New Thermal Spray Process to Produce Thin Films from Liquid or Gaseous Precursors

Christoph Hollenstein, Philippe Frédérique Bruno Guittienne, Malko Gindrat

New dedicated coating processes which are based on the well-known LPPS (TM) technology but operating at lower work pressure (100 Pa) are being actively developed. These hybrid technologies contribute to improve the efficiencies in the turbine industry such ...

Air cooling powered by façade integrated coloured opaque solar thermal panels

Andreas Schueler, Stefan Mertin

For building integration of solar-powered energy systems, aesthetic aspects play an importantrole. Covering a standard solar collector with a coloured glazing, opaque to the human eye but highly transparent to solar energy, permits a perfect architectural ...

U-Shaped Nano-Apertures for Enhanced Optical Transmission and Resolution

Hatice Altug, Arif Engin Cetin, Serap Aksu

The subject of light transmission through optically thin metal films perforated with arrays of subwavelength nanoholes has recently attracted significant attention. In this work, we present experimental and calculated results on optical transmission/reflec ...
