Description of LED Fluorescent:

Many phosphors(Florescent Powder) tend to lose efficiency gradually by several mechanisms. The activators can undergo change of valence (usually oxidation), thecrystal lattice degrades, atoms – often the activators – diffuse through the material, the surface undergoes chemical reactions with the environment with consequent loss of efficiency or buildup of a layer absorbing either the exciting or the radiated energy, etc.


Festures of LED Fluorescent:

Phosphor layers provide most of the light produced by fluorescent lamps, and are also used to improve the balance of light produced by metal halide lamps. Various neon signs use phosphor layers to produce different colors of light. Electroluminescent displays found, for example, in aircraft instrument panels, use a phosphor layer to produce glare-free illumination or as numeric and graphic display devices. White LED lamps consist of a blue or ultra-violet emitter with a phosphor coating that emits at longer wavelengths, giving a full spectrum of visible light.

Q: My wife went to the eye doctor to get new glasses (because she couldn't renew her driver's license with her glasses she had been using), and the doctor said that she wasquot;losing pigment" in both of her eyes. He said not to worry, but he wants her to make an appointment every 6 months, instead of just once a year.What does it (her losing pigment in her eyes) mean? Is it really nothing to worry about?(My wife doesn't seem worried, she hates going to doctor's but she trusts them when she goes to them; she doesn't ask questions-- she feels that if she needed to know something the doctor would tell her.)
I'm going thru the same thing, I have been to see my eye dr every 6 months to find out about pigment loss and I am losing my pigment at a fast rate 4 times worse than 6 mths ago. they are calling in the specialists about it, so YES worry!!!
Q: What is a pigment and their function in photosynthesis?
chlorophyl is the pigment i think. it is in the leaves of plants, that is where the photosynthesis takes place.
Q: Know this ounds kinda obvious but just wanted to confirm, is there more pigment in the middle of the beetroot than on the edges?
I've known it to be in the skin and thats from a cooking point of view.
Q: Please and thank you, it doesn't say so on the website.
Mac Pigment Ingredients
Q: (After the fifteenth century)
Pigment is color in powder form. An example is lamp black; it was first made from the soot of kerosene lamps ground fine. Binder is a substance used to hold pigment together and make it adhere; in the previous example, linseed oil would be the binder for the lamp black pigment. Vehicle is a medium acting as a solvent, carrier, or binder for paint; turpentine or mineral spirits would be a vehicle but so would linseed oil as well to help dilute the paint and help it cover a large area. Hope that helps and thanx.
Q: We see pigments everywhere in products. They make a variety of things we see today. Where does it come from? Do they actually take a red rose pedal, grind the color and designate it as the color red?
Yes, cheaper brands use actual dye. Like, literally dye, as in the stuff you can dye clothing with.
Q: I'm onto black-berry.. I wonder what else is available in 98362.
Pigments from the past came from rocks, minerals, plants, and other natural materials. Those things are all still available. You can take classes at some universities that teach how to make your own paints, or dry pigments. For native American pigments, you have to research which tribe used which colors. To be totally authentic you could visit the tribe of your choice and see if you can learn from them. Sticking to your own zip code will not net you much, usually.
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.
