However, in nuclear chemistry, the composition of the nucleus and the changes that occur there are very important.Īpplications of nuclear chemistry may be more widespread than you realize. Most chemists pay little attention to the nucleus of an atom except to consider the number of protons it contains because that determines an element’s identity. Although many people have an unfounded fear of radioactivity, smoke detectors save thousands of lives every year. When the current drops beneath a set value, another circuit triggers a loud alarm, warning of the possible presence of fire.Īlthough radioactive, the americium in a smoke detector is embedded in plastic and is not harmful unless the plastic package is taken apart, which is unlikely. When particles of smoke from a fire enter the smoke detector, they interfere with the ions between the metal plates, interrupting the flow of current. (This constant drain on the battery explains why the batteries in smoke detectors should be replaced regularly, whether the alarm has been triggered or not.)
The radioactivity of americium ionizes the air between the plates, causing a tiny current to constantly flow between them. Next to the plates is a small disk containing a tiny amount (∼0.0002 g) of the radioactive element americium. A battery in the circuit creates a voltage between the plates. This device is a smoke detector.Ī typical smoke detector contains an electric circuit that includes two metal plates about 1 cm apart. To avoid other conflicts, these plug-ins will also auto-deactivate the fonts upon closing a document.Most of us have at least one device in our homes that guards our safety and, at the same time, depends on radioactivity to operate properly. These plug-ins utilize Font Sense to precisely match and auto-activate the right font types when you open a document. Suitcase Fusion 2 comes with professional-grade auto-activation plug-ins for critical design and publishing apps, including InDesign, Illustrator, and QuarkXPress. It’s sleek, straightforward design makes it easy to locate, group, examine, preview and activate any font in your library. The new interface gives you the perfect excuse to mix a little play with your work. Not there yet? No worries, Suitcase Fusuion 2 also supports CS3 and QuarkXPress 7. Suitcase Fusion 2 is an early adopter too with seamless auto-activation support for Adobe InDesign and Illustrator CS4 and QuarkXPress 8.
Suitcase Fusion is the only industrial-strength font manager with precise Font Sense auto-activation, font repair functionality, and a central font repository, which provides unmatched sorting, searching, organizing and previewing capabilities, and eliminates duplicate font issues.
