Fluorescent materials in the form of quantum dots (nanocrystals of cadmium-selenide) were added to the abrasive slurries used in lapping and polishing glass samples in an attempt to tag damage sites as they were created during the material removal processes (Figure 1). Quantum dots that were trapped in these defects were then subject to laser excitation and imaged on a confocal fluorescence mic...

Look at the cloud-cat, lapping there on high With lightning tongue the moon-milk from the sky!

In the finishing process of optical glass, polishing with ceria, silica or zirconia slurry is conventionally adopted. The machining process, however, has problems involving inefficiency and a detrimental impact on the environment. Therefore, it is strongly recommended that the process be replaced with fixed-abrasive machining, but conventional fixed-abrasive tools have problems relating to low ...

The technology of ultra-precision machining, spanning almost three decades, has only in recent years experienced major advances in machine design and, subsequently, performance and productivity. In the 1970’s, ultra-precision machining techniques were successfully adopted for the manufacture of computer memory discs used in hard drives, and also photoreceptor components used in many photocopier...
