Microfluidic Cell Culture Chambers with Nanoporous Walls for Chemical Communication

Reconstruction of phylogenetic trees based on 16S rRNA gene sequencing reveals that so far only a tiny fraction of microbial diversity has been cultured in the laboratory. One major reason behind this "unculturability" is that many microbes function in symbiosis, frequently exchanging metabolites to sustain their own metabolism, while key exchanged metabolites have hardly been identified. To ad...

Vacuum-cleaning system for isolation chambers.

To encourage the utilization of the isolation chamber as a research tool, the cost of its use should be lowered. Methods and devices must be developed which make more efficient use of the space within the isolator and allow the operator to work more effectively in this confined area. A simple vacuum-cleaning system is described; it consists of a nozzle and flexible hose which connect through th...

Extruded Aluminum Vacuum Chambers for Insertion Devices

Extruded aluminum vacuum chambers are commonly used in the storage rings of synchrotron facilities. For 18 years the APS has designed and fabricated vacuum chambers made from extruded aluminum for use with insertion devices at the APS and for use at other facilities including BESSY II, the Swiss Light Source (SLS), the Canadian Light Source (CLS), the TESLA Test Facility (TTF), and the European...
