Langmuir probe diagnostic studies of pulsed hydrogen plasmas in planar microwave reactors
Langmuir probe techniques have been used to study time and spatially resolved
electron densities and electron temperatures in pulse-modulated hydrogen
discharges in two different planar microwave reactors (fmicrowave= 2.45 GHz,
tpulse= 1 ms). The reactors are (i) a standing-wave radiative slotted waveguide
reactor and (ii) a modified travelling-wave radiative slotted waveguide
reactor, which generate relatively large plasmas over areas from about 350 cm^2
to 500 cm^2. The plasma properties of these reactor types are of particular
interest as they have been used for basic research and for plasma processing,
e.g. for surface treatment and layer deposition. In the present study the
pressures and microwave powers in the reactors were varied between 33 and 55 Pa
and 600 and 3600 W, respectively. In regions with high electromagnetic fields
shielded Langmuir probes were used to avoid disturbances of the probe
characteristic. Close to the microwave windows of the reactors both the
electron density and the electron temperature showed strong inhomogeneities. In
the standing-wave reactor the inhomogeneity was found to be spatially modulated
by the position of the slots. The maximum value of the electron temperature was
about 10 eV and the electron density varied between 0.2 and 14*10^11 cm^-3. The
steady state electron temperature in a discharge pulse was reached within a few
tens of microseconds whereas the electron density needed some hundreds of
microseconds to reach a steady state. Depending on the reactor the electron
density reached a maximum between 80 and 200 microseconds after the beginning
of the pulse.Comment: 16 pages including 18 figures. The following article has been

Mass spectrometry-based draft of the mouse proteome.
The laboratory mouse ranks among the most important experimental systems for biomedical research and molecular reference maps of such models are essential informational tools. Here, we present a quantitative draft of the mouse proteome and phosphoproteome constructed from 41 healthy tissues and several lines of analyses exemplify which insights can be gleaned from the data. For instance, tissue- and cell-type resolved profiles provide protein evidence for the expression of 17,000 genes, thousands of isoforms and 50,000 phosphorylation sites in vivo. Proteogenomic comparison of mouse, human and Arabidopsis reveal common and distinct mechanisms of gene expression regulation and, despite many similarities, numerous differentially abundant orthologs that likely serve species-specific functions. We leverage the mouse proteome by integrating phenotypic drug (n > 400) and radiation response data with the proteomes of 66 pancreatic ductal adenocarcinoma (PDAC) cell lines to reveal molecular markers for sensitivity and resistance. This unique atlas complements other molecular resources for the mouse and can be explored online via ProteomicsDB and PACiFIC
