This invention relates to carbon compounds, and more particularly to morpholine compounds and their preparation. And, in accordance with the invention certain novel compounds may be had, which are capable of important usages in the fields of photographic developers, local anesthetics, anti-oxidants,....
Chemical sunscreens contain organic (carbon-based) compounds that absorb the sun’s harmful rays and convert them into harmless heat, while mineral sunscreens use inorganic compounds, like zinc oxide or titanium dioxide, to block rays and reflect them away from the skin. ...
Fabrication of an electron-emitting device entails distributing electron-emissive carbon-containing particles (22) over a non-insulating region (12). The particles can be made electron emissive after
