The last triennium, and coincidentally the last few years of the 20th century, has been a most remarkable time for Commission 9, and for astronomy in general. Ground-based astronomy in particular has received an enormous boost due to the arrival of a

Warfarin enantiomerrs that have previously been reported to be difficult to separate on cyclodextrin bonded high-performanceliquid chromatographic supports can be easily and completely resolved on a stationary phase obtained by deposition on silica o

Several β-cyclodextrin (β-CD) chiral stationary phases (CSP) for HPLC were prepared, from silica beads coated with polyvinylimidazole (PVI). The functionalization carried out by reaction with 3-chloro-2-hydroxypropyl β-CD, gave rise to supports wi

Long-focal-length microlens arrays is one of the main components of the Shack- Hartmann type wavefront sensor. For an application in astronomy we have developed a specific microlens manufacturing process based on photolithographic techniques. At firs

We present the focal instrumentation set up on the 2-m telescope at Pic du Midi, France developed to achieve third order aberration corrections on turbulence-degraded images using a photon-counting detector, a wavefront sensor, and a deconvolution me

For fast photon counting cameras and their applications, present centroiding electronics are not fast enough to match the pixel rate. We are designing a new architecture for the centroiding process. The basic principle is to select only the useful pi

Microlens arrays made by engraving photoresist coatings are suitable for astronomical applications, especially in the Shack-Hartmann type of wavefront sensor. Their characteristics have to be carefully chosen to fit the turbulence strength. Our instr

Cyclomaltoheptaose (β-cyclodextrin, 1) can act as a phase-transfer catalyst owing to its ability to form host-guest complexes. Reaction of 1 with 2,3-epoxy-propyltrimethylammonium chloride (2) gave mainly 2-O-(2-hydroxy-3-trimethyl-ammoniopropyl) de
