Infrared array imaging and spectrophotometry of the nuclear region of the 'hot-spot' galaxy NGC 2903
Previous studies of the hot-spot galaxy NGC 2903 at a variety of wavelengths have shown that considerable star formation is occurring within the complex hot-spot structures in this galaxy's nuclear region. A K-band (2.2 microns) image of the galaxy's nuclear region has been obtained with an infrared CCD and compared to V-band (0.55 micron) and 1-micron

Regional Differences of Hemodynamics and Oxygenation in the Human Calf Muscle Detected with Near-Infrared Spectrophotometry [PDF]
Measurements in muscle tissue are often performed at a selected single location over the muscle of interest. The hypothesis is that the values obtained reflect the status within the entire muscle or muscle group. This, however, may not be the case. The study was performed to investigate whether this hypothesis is true for hemodynamics and oxygenation ...

Synthesis and Characterization of SCDs/TiO2 Composite
Synthesis of sulphur-doped carbon nanodots immobilized on the TiO2 surface (SCDs/TiO2) composite was carried out using the sol-gel method with SCDs and titanium tetraisopropoxide (TTIP) as precursors. SCDs were prepared from citric acid monohydrate, urea,
