ROSAT observations of the dwarf starforming galaxy Holmerg II (UGC 4305)

, 1999
We present ROSAT PSPC and HRI observations of the dwarf irregular galaxy Holmberg II (UGC4305). This is one of the most luminous dwarf galaxies (Lx~ 10^{40} erg s^{-1} cm^{-2}) detected in the ROSAT All-Sky Survey.

Development and Application of Full Spectrum Direct Reading Arc Emission Spectrometer E5000 and Its Application in Geochemical Sample Analysis

Yankuang ceshi, 2015
In geochemical sample analysis, some elements such as Ag, B, Sn are difficult to analyze. Traditional alternating current Arc Emission Spectrometry is used to analyze them, for example Spectrograph and Multi-channel Arc Emission Spectrometer.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Real-Time Plasma Process Condition Sensing and Abnormal Process Detection

Sensors, 2010
The plasma process is often used in the fabrication of semiconductor wafers. However, due to the lack of real-time etching control, this may result in some unacceptable process performances and thus leads to significant waste and lower wafer yield.

Optical spectra of a quantum dot in a microcavity in the nonlinear regime

, 2008
The optical emission spectrum of a quantum dot in strong coupling with the single mode of a microcavity is obtained in the nonlinear regime. We study how exciton-exciton interactions alter the emission spectrum of the system, bringing the linear Rabi ...
