New Sorbent from Agro-industrial Waste and its Potential Use in 17ß-Estradiol and 17α-Ethynylestradiol Removal
Suzimara Rovani*, Éder C. Lima, Renato Cataluña, Andreia N. Fernandes

In recent years, the increasing introduction of new chemicals in the market, and the development of more accurate analytical methods, added a variety of endocrine disruptors compounds (EDC). Even though they are found in very low concentrations (range of ng L-1) there is still a lack of knowledge about long-term risks of EDC for non-target organisms as well as for human health.

Droplet Microfluidics for 3D Epithelial Cell Culture
Monika Dolega (Pyzalska), Xavier Gidrol, Nathalie Picollet-D’hahan

The challenge facing 3D cell culture today is to adapt current models to a systems biology approach - in particular, to enable RNA interference-based screens to study the effects of the microenvironment on cellular function.

Design of Mixed-Criticality Applications on Distributed Real-Time Systems
Domit?ian Ta?mas?-Selicean and Paul Pop

In this thesis, we are interested in mixed-criticality applications (both in the safety and time domains) implemented using heterogeneous processing elements (PE) interconnected using TTEthernet. We address the problem of synthesizing mixed-criticality applications on partitioned architectures, at the PE level and at the communication level.

Isolation, Identification, and Determination of Designer Anabolic Steroids Commonly Found in Dietary Supplements
Sarah E. Voelker, M.S.; Travis M. Falconer, Ph.D.; Jonathan J. Litzau; Mary B. Jones; Lisa M. Lorenz

A general analytical approach in identifying emerging steroid-like compounds is presented, including analysis by GC-MS, LC-MS, and/or HPLC-UV. Isolation of unknown compounds was achieved by high performance liquid chromatography with fraction collection. Isolated compounds were characterized by Nuclear Magnetic Resonance spectroscopy and high resolution accurate mass-mass spectrometry to elucidate their structure.

Microfluidic chips with microscale traps for cancer cells study by confocal laser scanning microscopy
K.I. Belousov (1),, I.V. Kukhtevich (1,2), A.S. Bukatin (2,3), A.A. Evstrapov (1,2,3)

In this work, microfluidic chip with integrated microscale hydrodynamic traps for fixation of cancer cells in native state to study by confocal laser scanning microscopy in the chip’s chamber was designed, fabricated and tested.

Direct On-chip Storage and Release of Liquid Reagents for Diagnostic Lab-on-a-Chip Devices
Daniel Czurratis*, Thomas Brettschneider*, Yvonne Beyl*, Sven Zinober*, Franz Lärmer*, Roland Zengerle**

We present a direct on-chip storage and release of liquid reagents for diagnostic lab-on-a-chip devices. Reagent release is pressure driven and realized by braking up a barrier film through a deflection of a flexible membrane.

Polymerized Poly(ethylene glycol) Diacrylate Microfluidic Membrane Valves
Chad I. Rogers, Joseph B. Oxborrow, Long-Fang Tsai, Gregory P. Nordin, and Adam T. Woolley

Polymerized poly(ethylene glycol) diacrylate (poly-PEGDA) was fabricated into pneumatically controlled, non-elastomeric membrane valves as a nonspecific adsorption resistant alternative to polydimethylsiloxane valves. Temporal response, valve closure, and long-term durability of these poly-PEGDA valves were evaluated.
