  • Publication number: 20240192588
    Abstract: A reticle enclosure includes a base including a first surface, a cover including a second surface and coupled to the base with the first surface facing the second surface. The base and the cover form an internal space that includes a reticle. The reticle enclosure includes restraining mechanisms arranged in the internal space and for securing the reticle, and structures disposed adjacent the reticle in the internal space. The structures enclose the reticle at least partially, and limit passage of contaminants between the internal space and an external environment of the reticle enclosure. The structures include barriers disposed on the first and second surfaces. In other examples, a padding is installed in gaps between the barriers and the first and second surfaces. In other examples, the structures include wall structures disposed on the first and second surfaces and between the restraining mechanisms.

  • Patent number: 9029394
    Abstract: 2-aryl-4-quinolones are converted into phosphates by reacting with tetrabenzyl pyrophosphate to form dibenzyl phosphates thereof, which are then subject to hydrogenation to replace dibenzyl groups with H, followed by reacting with Amberlite IR-120(Na+ form) to form disodium salts. The results of preliminary screening revealed that these phosphates showed significant anti-cancer activity. A novel intermediate, 2-selenophene 4-quinolone and N,N-dialkylaminoalkyl derivatives of 2-phenyl-4-quinolones are also synthesized. These novel intermediates exhibited significant anticancer activities.
