The role of groundwater colloids influencing mobilization or immobilization of actinides in natural aquatic systems is addressed in the context of safety aspects of nuclear waste disposal. Groundwater colloids from the Gorleben site (Lower Saxony, northwest Germany) are characterized in the presence of Eu(III) as a homologue for trivalent actinides. Scanning transmission X-ray microscopy (STXM) measurements...

We present the integration of enzyme-based lactate and glucose biosensors into hanging-drop networks. Hangingdrop networks are an ideal microfluidic platform for formation, cultivation, and continuous and long-term observation of 3D microtissues. The implementation of biosensors enables in-situ online monitoring of the effects of different culturing conditions and compound dosages on the microtissues...
We present a biosensor system comprising a chip with an array of silicon nanowire ISFETs and a CMOS chip with the signal-conditioning circuitry. An array of 48 silicon nanowires has been patterned via e-beam lithography. The on-chip circuitry is used to monitor the resistance of the nanowires by applying a constant voltage and measuring the respective current. The analog signal is then digitized on...
Biosensor microprobe arrays for the simultaneous in vivo detection of the neurotransmitters choline and L-glutamate are presented. Combined with a custom-developed CMOS chip, comprising 24 potentiostatic circuits, recordings can be performed at high signal-to-noise ratio in multiple areas of a rat's brain in parallel. The functionalization to create selective enzyme electrodes is based on electrochemical...
This paper reports on a differential impedance spectroscopy system for single-cell analysis, which also features an optical setup with machine-vision that simultaneously provides optical data for a direct comparison. Such a combined setup allows for benchmarking the differential impedance spectroscopy against the optical data in a quantitative way. Here we present simultaneously acquired optical and...
In 2007, SEMI's information and control committee approved a new version of SEMI E94 (E94-1107). This version relaxed the connection between carriers and control job for processing wafers and formally introduced a way to redirect material based on host requests after the beginning of processing. As simulations indicate, this new standard is impacting several fab performance indicators, including throughput,...
This paper presents the results of joint efforts by AMD, Qimonda, InReCon and Peer Group to identify overhead transport (OHT) performance limitations in 300 mm fabs as well as propose how to overcome some of these limitations by standardizing the handling of common exceptions.
This paper analyzes the effects of small lot manufacturing (SLM) on equipment operation and fab performance. It also discusses equipment front-end design challenges and describes options for carrier handling and AMHS operation to maximize the productivity benefits of small lot manufacturing. This paper focuses primarily on the material handling aspects of SLM and as such, does not discuss the influences...
