Cancer Treatment A cancer treatment in which glass microspheres deliver radioactivity directly to diseased areas in the body is currently being tested. Canada already uses the treatment, which shows success for liver cancer, and may be appropriate for other cancers. The treatment is promising, because it replaces the need for external beam radiation, which can cause unnecessary damage to healthy surrounding tissues. Too large to pass outside of the diseased liver, the spheres remain harmlessly in the organ even after their radioactivity has disappeared. Newsletters Fun Activities Chocolate, like glass, is cooled rapidly to form a noncrystalline solid.
All electronic devices use microelectronic packages or integrated circuits in order to function.
These packages are fragile and must be protected from corrosion. Even the slightest corrosion of any of the elements in the package will impair operation. One form of protection is to encapsulate the package in glass.
