We have obtained spatially resolved near-infrared spectroscopy of the Venus nightside on 15 nights over three observing seasons. We use the depth of the CO absorption band at 2.3μm to map the two-dimensional distribution of CO across both hemispheres. Radiative transfer models are used to relate the measured CO band depth to the volume mixing ratio of CO. The results confirm previous investigations...
Near-field scanning optical lithography (NSOL) is a relatively new technique for patterning delicate organic thin films. Here, it has been used to fabricate a thin film optical phase grating in the semi-conducting polymer poly(p-phenylene vinylene). Recent advances in the development of the NSOL technique have been exploited to demonstrate its capability for producing photonic structures with nanoscale...
