Festures of LED Fluorescent:

Fluorescent powder, also called phosphor, most generally, is a substance that exhibits the phenomenon of luminescence. Somewhat confusingly, this includes both phosphorescent materials, which show a slow decay in brightness (> 1 ms), and fluorescent materials, where the emission decay takes place over tens of nanoseconds. Phosphorescent materials are known for their use in radar screens and glow-in-the-dark toys, whereas fluorescent materials are common in cathode ray tube (CRT) and plasma video display screens, sensors, and white LEDs.

Q: What are MAC eyeshadow pigments? Are they just like regular eyeshadow.. are they used the same way? Has anyone tried them and liked them?: NEVER TRIED THEM HEARD GOOD THANGS THO

Q: can the pigment know as Chinese purple form a matter wave in certain circumstances?: Scientists explore atomic mysteries of ancient pigment LOS ALAMOS, N.M., Nov. 18, 2004 -- University of California scientists from the National High Magnetic Field Laboratory, Pulsed Field Facility at Los Alamos National Laboratory, working with colleagues from Tokyo Metropolitan University, the University of Buenos Aires in Argentina, the National Institute of Chemical Physics and Biophysics in Estonia, the National High Magnetic Field Laboratory in Tallahassee, Florida and the University of Tokyo, have discovered an ideal candidate for Bose-Einstein condensation in the ancient Chinese pigment, Han Purple. In research featured recently on the cover of Physical Review Letters, the team describes how the application of a strong magnetic field to Han Purple (BaCuSi2O6) creates a gas of bosonic spin triplet excitations. The field acts as a chemical potential causing the weakly interacting bosonic gas to undergo Bose-Einstein condensation (BEC) when the temperature is reduced to minus 453 degrees Fahrenheit, six orders of magnitude higher than the temperature normally required for BEC in atomic gases.

Q: pretty self-explanatory...: Pigments help in making food for the plants they also give color to it.Pigments are of different types which give different color to its leaves or fruits.Like mango is green first and then turns yellow coz green pigment is replaced by yellow pigment. Green pigment in most of the fruits is present only till it requires food and is raw.

Q: How do you use pigments?: You can use Pigments for multiple things, eyes, cheeks and lips. -Eyes: With your clean fingers or with a small eyeshadow brush apply the pigment gently to your lids. If its a light color like white, apply it on the inner corner and under the brows. If its darker, like dark brown, apply it on the crease. You can also use it to line your eyes, I like to mix pigments with some moisturizer and with a really thin brush line my eyes. If its a matte pigment (with no shimmer or glitter) you can use it to fill in your brows. Lastly, you can use it on your lashes! I use some hair gel or clear mascara and I mix it with some pigments, I apply it with my finger or with an old mascara wand :) -Cheeks: Use it as a blush if its a pink, red, orange or coral color. Apply a small amount with a blush brush onto the apples of your cheeks. If its a white, very light brown or pink, use it as a highlighter. Apply with a small brush under you undereye area. If its a darker brown, use it as a bronzer or conturing powder. -Lips: Mix pigments with vaseline, olive oil or clear lipbalm to get a tinted gloss. If you want more precision, use a small brush to apply it. As you can see, Its all about the brush you use!! Hope it helped :)

Q: how are the pigments in clothes differ from plant pigments?: Pigments are pigments. They are made of molecules that absorb some colors and reflect others from the visible spectrum of light, which gives everything color. Black pigments absorb everything and reflect nothing, so black is the absence of color and it is why dark clothing are warmer in winter. White pigments reflect everything and absorb nothing, so clothing that is white is cooler in summer. Most plants have more chlorophyll, a green pigment, in them than other pigments, so the plant is overwhelmingly reflecting green back to our eyes and absorbing the red and blue ends of the spectrum. In fall, when the chlorophyll breaks down, we can see the yellow, orange, and red pigments that are also in the leaf for a few weeks. In this way, all pigments are alike. However, perhaps what your teacher is looking for is that the green pigment chlorophyll in plants not only absorbs red and blue wavelengths of light, it also uses that energy to excite electrons from the molecules of chlorophyll and send them through an electron transport chain that enables light energy to be converted to chemical energy and store it in the C-H bonds of glucose, which is made during photosynthesis. Other pigments, whether they be in clothes or other objects such as cars or just about anything else do not do this. Only plant chlorophyll, or the green pigment in plants, converts light energy to chemical energy. That is the one huge difference. Otherwise, like all other pigments, chlorophyll absorbs some wavelengths of light and reflects others, in the case of chlorophyll, green wavelengths of light.

Q: What are the roles and type of plant pigments?: Pigments are able to absorb specific wavelengths of light which power photosynthesis. Chlorophyll, which is green, absorbs all wavelengths except green. Each photon excites an electron in the light harvesting complexes of a photosystem in a chlorophyll molecule, eventually producing ATPs. Other pigments will be a different color and will be able to absorb other wavelengths, maximizing energy absorbency when the sun's rays change. Pigments are chemicals inside living things that absorb certain types of light. In plants, the pigment chlorophyll in leaves absorbs sunlight for photosynthesis to work, where the energy comes from. Chlorophyll absorbs all light except green, which is reflected. That's why most plants are green...

Q: why do plants need more than one pigment for light absorption?: Pigments are molecules with an array of covalent bonds capable of absorbing a photon of light that has only a certain wavelength. The absorbed wavelength is only a fraction of the continuous range of wavelengths reaching the reaction center of a chloroplast. Each pigment species absorbs a different portion of the spectrum. So most photosynthesis works in combinations of pigments to absorb a across the visible spectrum and somewhat beyond. Some pigments (accessory photosynthesis carotenoid pigments) absorb useful wavelengths to pass the energy to chlorophyll A while the Xanthophyll Cycle pigments absorb potentially harmful high energy wavelengths for dissipation. Accessory pigments provide a range of spectra collection that allowed plants to adapt successfully to environments of differing light conditions. Pigments provide coloration to signal flower or fruit maturity to pollination partners or seed dispersal partners. Anthocyanins and carotenoids perform these communication functions. Phytochrome is a pigment that absorbs one wavelength only to toggle to another shape capable of absorbing at a different wavelength. Algae and plants both use this system to inform them of the time of year so they can synchronize with the best season in their habitat for reproduction efforts to succeed. Plants use phytochrome to regulate the photoperiod of flowering or seed germination.

Q: How can you extract pure pigments from a sample of leaves in a form that you could test the absorbency of the various pigments??I don't know how to extract enough pigment in order to fill a cuvette and measure the absorbance, please help!! :D: Separation of plant pigments using chromatography. Paper chromatography is a useful technique in the separation and identification of different plant pigments. In this technique, the mixture containing the pigments to be separated is first applied as a spot or a line to the paper about 1.5 cm from the bottom edge of the paper. The paper is then placed in a container with the tip of the paper touching the solvent. Solvent is absorbed by the chromatographic paper and moved up the paper by capillary action. As the solvent crosses the area containing plant pigment extract, the pigments dissolve in and move with the solvent. The solvent carries the dissolved pigments as it moves up the paper. The pigments are carried along at different rates because they are not equally soluble. Therefore, the less soluble pigments will move slower up the paper than the more soluble pigments. This is known as developing a chromatogram.

Q: I am planning on purchasing MAC, but what r the differences... thanks to all...I want to have an idea before I head to the mall.: Pigments are really loose eye powders. For MAC, it's kind of like 'balls of sparkles' If you want really sparkly eyes, you'd probably want this. Dip your eye makeup brush in water, then in the pigment. I find this to work well, and it really compliments the product. It's best applied over a dark eyeshadow or primer. An eyeshadow is a packed together powder. (As you probably know) MAC eyeshadow comes on bright and radiant. So if you just want a simple look, this product works well. I suggest MAC - PaintPot. It's a creamy eyeshadow that is easy to blend. It's not waterproof, but it's difficult to rub off. It can act as a primer too.
