Reed Diffusers – An Explanation Of What They Are And How They Work

Article by Alex Muir

Reed Diffusers And How They WorkThe expression “home fragrances” is a relatively recent introduction to everyday language. It encompasses a variety of different products, the most well known of which – and certainly the most popular – is the scented candle. But you can also choose from room sprays, air fresheners, incense sticks and, increasingly commonly, reed diffusers. Diffusers are fast becoming a convenient alternative to scented candles, so we thought we would spend a few moments explaining a little about them to the uninitiated.So, what exactly is a reed diffuser? They are usually made up of three distinct elements: a bottle or container, scented oil, and the rattan reeds which distinguish the diffusers from other home fragrancing options. The bottles or containers are available in an assortment of shapes and sizes, from a simple clear jar to something much more ornate. The fragrant oil is placed in the jar, followed by the reeds. The oil travels up and through the reeds before being distributed throughout the surrounding atmosphere. The size of diffuser does not necessarily determine its potency, but you may very well choose a small diffuser in a bathroom whereas a reception room in a doctor’s office may require something larger to ensure the fragrance fills the entire room. Reed diffusers are easy to use. They are a safe, convenient alternative to candles as they do not require a flame to work and, once set up, are virtually maintenance free. To start using your diffuser, simply remove the packaging and set all the constituent parts on a flat surface. Then, uncap the bottle of oil and pour it into the empty jar or else simply uncap the container in which the oil is already housed. Then all you have to do is place the reeds into the filled container and enjoy the delightful aroma. The reeds have microscopic straw-like capillaries which when immersed in the oil soak it up and carry it along the whole reed. Please be aware that all reed diffusers are not the same. Put simply, when it comes to diffusers, as with scented candles, you get what you pay for. Premium quality scented candles and diffusers use high quality fragrant or essential oils which are obtained from plants, barks and other botanicals, meaning you receive a product which produces a natural subtle aroma which lasts much longer than cheaper alternatives made with synthetic fragrances. Another consideration is the reeds themselves. To work properly you must use rattan reeds which have the correct internal structure to allow the oil to diffuse properly. Cheap diffusers use wooden sticks which simply do not work and will leave you with a feeling of deep disappointment as well as empty pockets.Where can you use reed diffusers? Reed diffusers are perfect for using anywhere around the home, but because they do not rely on a flame to operate they are also eminently suitable for use in the workplace. At home they are perfect for using in reception areas to greet visitors with a lovely aroma as they enter your home, as well as in bathroom and, of course, the bedroom where diffusers with the natural fragrance of plants such as lavender or chamomile can help you relax and aid restful sleep.But basically, wherever you have a room, then you can use a reed diffuser. Shop owners use them to help create a pleasant and relaxing shopping experience. Reed diffusers can be found in waiting rooms of solicitors and dentists, where they can help clients relax. They are recommended by estate agents for use in the home before you have viewers over to inspect a house for sale. The list is virtually endless. Why not try one yourself today?

Question by bookworm: How to scanning electron microscopes and transmission electron microscope work?
i’m studying them in my science class, however the textbook is out of date and all the sites i’ve looked up give me various, different answers.
does anyone know a not too complicated way to explain how they work?

Answer by trb0257
The old SEM i used in the 80′s, a bulb which high currents passes through, providing a high energy x-ray source. the chamber is vacuum of all air, and supercooled with liquid nitrogen. the x-rays pass through a series of magnetic rings to narrow the beam, which is rasped, (moved back and forth like the old TV’s CRT), of a specimen. the specimen must be made non-conductive, by sputter coating it with graphite or other materials. A SEM, gives us a good visual of the surface of a specimen, and when the specimen is hit with narrow focused electron beam between 100 and 300 thousand volts, it gives off secondary x rays, which are picked up by crystal detectors (EDXRA). these detectors can give counts of secondary x-ray wavelengths specific to elements. different type detectors can pick up different elements, because some wavelengths overlap. advantage, SEM can take a large specimen, sample may only may need little preparation,

without the vacuum, air molecules bounce the beam, and if too much air, it can have a arch of electrons like a bolt of lighting.

a TEM has much higher magnification, is designed to look through very thin specimens, to get not surface as a SEM does, but to look inside a cell for example, , and different type of analysis can be done, we used crystal diffraction, see crystal structure at atomic level on asbestos fibers. the advantage, very high magnification, can see inside specimen in 3-D, the drawback, it takes long time to get a sample to the level, thin enough, it can be looked at in a TEM
