Unlike the fluorescent colors of quantum dots
, the colors emitted by the new carbon dots
depend on the color of light that the researchers use to excite them.
AIST plans to develop surface treatment techniques for quantum dots
to specifically label objectionable fungi and foreign substances invading various food production processes including the production of fermented food, and apply the techniques developed to evaluation of the optimal process management.
Hiring outside consultants also makes sense when a special expertise is required that may not be readily available within the downsized DOT
The results showed that the children were usually able to pick the larger set, even if the dots
were different sizes and took up different amounts of space.
The late Herb Caen was the last master of the "three-dot
" style: that journalistic anachronism in which short items are separated by three dots
(technically they're "ellipses.
We have to separate [pictures] into dots
to create the illusion that there are many colors on the page," said Bob Schrimpf, a technician who helps transform artwork into the metal press plates that print our pages at Quad.
SEVEN UP As it turns out, Nozik's crew was focused on the wrong quantum dots
has been in a closed Beta test, but the site is now available to the public.
Compared with conventional fluorescent labels, which are typically made of organic molecules and come in only a few colors, quantum dots
are brighter, and stabler, and can be tuned to emit a variety of wavelengths simply by varying the size of the particle.
com) today introduced the first commercially available non heavy-metal quantum dot
product for life science research, its Molecular Plate T2-MP EviTags(TM).
Chan published one of the two simultaneous reports that showed how semiconductor quantum dots
could tag cells with microscopic beacons of light.
are nanoscale crystals of semiconductors that behave as single "super atoms.
