Design and Fabrication of Multilayer Piezoelectric NEMS Resonators

We have successfully demonstrated the fabrication of self-actuating multilayer NEMS resonators including cantilevers and double clamped beams. Resonant sensors are widely used as precision mass sensors for the detection and quantification of small concentr ...

High-throughput computational screening of nanoporous adsorbents for CO2 capture from natural gas

Berend Smit, Efrem Daniel Braun, Sondre Kvalvag Schnell

With the growth of natural gas as an energy source, upgrading CO2-contaminated supplies has become increasingly important. Here we develop a single metric that captures how well an adsorbent performs the separation of CH4 and CO2, and we then use this metr ...

Optical-resolution photoacoustic imaging through thick tissue with a thin capillary as a dual optical-in acoustic-out waveguide

Demetri Psaltis, Christophe Moser, Nicolino Stasio, Emmanuel André Henri Bossy

We demonstrate the ability to guide high-frequency photoacoustic waves through thick tissue with a water-filled silica-capillary (150 mu m inner diameter and 30 mm long). An optical-resolution photoacoustic image of a 30 mu m diameter absorbing nylon threa ...

Enhanced Plasmid DNA Utilization in Transiently Transfected CHO-DG44 Cells in the Presence of Polar Solvents

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Yashas Rajendra, Divor Kiseljak, Sowmya Balasubramanian

Although the protein yields from transient gene expression (TGE) with Chinese hamster ovary (CHO) cells have recently improved, the amount of plasmid DNA (pDNA) needed for transfection remains relatively high. We describe a strategy to reduce the pDNA amou ...

An Innovative Technique for Water Retention Characterization of Highly Swelling Geomaterials

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

This paper presents an innovative method called Micro-cell technique to obtain the water retention curves of geomaterials particularly highly swelling clays such as MX-80 bentonite. This method is based on the controlled water content and measured suction ...

Microalgal carotenoid recovery in a biorefinery approach

Christof Holliger, Christian Ludwig, Jean-Paul Schwitzguebel, Mariluz Bagnoud, Olivier Laurent Emery

Introduction Microalgae culture to be effective as feedstock for bio-energy production needs to overcome constraining biotechnological, technological and economic factors [1]. In order to establish an economically viable process, the co-production of renew ...

Discovery of a novel pharmacological and structural class of gamma secretase modulators derived from the extract of Actaea racemosa

Patrick Fraering

A screen of a library of synthetic drugs and natural product extracts identified a botanical extract that modulates the processing of amyloid precursor protein (APP) in cultured cells to produce a lowered ratio of amyloid-beta peptide (1-42) (Aβ42) relativ ...

Method For Predicting Adsorbent Performance

Berend Smit

A method for predicting selective performance of an adsorbent is disclosed. The adsorbent is selected from a list of metals and/or metal cations for use in removing contaminants as thiophene derivatives in hydrocarbon feed. The metals or metal cations are ...

Lead salt resonant cavity enhanced detector with MEMS mirror

Niels Quack

We describe a tunable resonant cavity enhanced detector (RCED) for the mid-infrared employing narrow gap lead-chalcogenide (IV-VI) layers on a Si substrate. The device consists of an epitaxial Bragg reflector layer, a thin p-n+ heterojunction with PbSrTe ...
