Early detection of trace amounts of toxic gases in an open environment is vital for any successful attempt to contain subsequent damage. The sensors used must respond quickly and reliably in such a situation. A typical method to increase sensitivity is to use sensors that have a large exposed area. It is also desirable for the sensor to be small in size and to consume low power. These characterist

Composite fibers of single walled carbon nanotubes dispersed in poly(methyl methacrylate) and polystyrene are prepared using electrospinning. The single fiber electrical conductivity is measured as a function of the composition of carbon nanotubes. A noncontact method of measuring the carrier mobility at microwave frequency (14 GHz) using bimodal cavity is employed. The mobility measurements indi

Scientists from Japan Advanced Institute of Science and Technology show highly polarized photoluminescence (PL) from aligned polyethyleneoxide: polyphenylenevinylene derivative composite nanofibers. They demonstrate PL polarization ratios (parallel to perpendicular) greater than 13. This ratio is further increased (up to ~25) by stretching the nanofibers. According to authors, these results open u

Scientists developed a new and simple electrospinning method for producing aligned helical polymer nanofibers. The helical fibers were collected by a tilted glass slide. These helical structures were formed by jet buckling due to mechanical instability when hitting collector surface. Formation of the helical structures is dependent on the obliquity of the tilted glass slide and distance away from

It's a new endeavor of an old love...I used FIMO when it first hit the market. Most of the pieces I sold or gave away - I have only a few beads, and two pendants I just didn't have the heart to let go of left from those days.Fast forward to a day I feel compelled to work with clay but can't get to a ceramic studio and don't have the fingers to use FIMO classic - working out the hard, finger-gnarling clay. I found FIMO soft! I bought a few colors to test it out and now have a nice collection, create my own colors by mixing, AND serve the Muse by creating some sculptured jewelry!I was extremely pleased to see that Peggy, of Lucky Girl Trading Co and fellow Etsy artist, had written a very nice feature about these new pendants on her blog Lucky Girl Trading Co. - Make Every Day Your Lucky D

Wuuah..... *Stretchaysss* After 2 months and a little more of torture, Semester 4 BPharm will be coming to an end... Soon. Still got 3 more weeks until our study break. In the meantime, I'll just happily drift along with the crowd. :P But then, there's still this Pharmaceutical Analysis portfolio to deal with. T-T Haih.... T-TYesterday, I tried making stuff with the polymer clay I bought off eBay. The clay is quite tough but surprisingly very pliable and kneadable. It holds its shape quite well, unlike the normal plasticine we play with. The texture is a bit like Play-Doh, only much more workable and easier to get the shape you want.I wanted to make use of most of the colours - incorporate them all in one special charm. So what came to my mind was - a lollipop. :D Well, maybe it's because

An American-Korean team developed a new method for making wrinkled hard skins on the surface of polymers employing a focused ion beam. By controlling the direction and intensity of the ion beam, they literally carved patterns on flat areas of polydimethylsiloxane, a silicon-based organic polymer (the main ingredient in Silly Putty), by changing direction and [...]

By Astrid Lee, http://www.eArtfair.com/blog - Copyright 2007 To create beautiful polymer clay beads for your fine art jewelry, there are a number of steps you should take to ensure that right from the beginning you’re able to make a rather professional, artistic product, in an economical way. Article from http://www.eArtfair.com/blog FIRST THE BASICS: TIPS FOR USING POLYMER CLAY 1. Be a clean worker. That maeans work on clean surfaces and ensure clean hands. This practice keeps your work looking smooth and bright. 2. Polymer clay is typically softened by the heat of hands. Just knead it gently when taking it out of the pack. 3. Do not over- or under-bake your polymer clay. Instead, follow the instruction of your particular polymer clay (brand and type) you are using exactly, and you will get your baking just right. Each clay is slightly different and manufacturers will inform you of its unique nature and baking requirement. 4. While general household tools are useful for workin

If your old speakers are looking worn and tatty then you should consider buying these beauties! Ok, so at $24,990 the pair you may be saving for a while but they’re so pretty! These Polymer Logic speakers from Polymer Audio Research apparently have more pure diamond and gold than you’ll find in any $500,000 diamond ring - that’s some bling right there! The loudspeakers use diamond cone midrange drivers each side, Supravox TG1 tweeter and a pair of hand made vapor deposited titanium cone woofers - Abba never sounded so good! Not only that but the Polymer Logic’s titanium dome tweeters are covered with a pure layer of solid gold. So, anyone fancy a pair of $24,990 speakers?

Researchers have developed a new method for producing tandem solar cells, in which two solar cells working together to use a wider range of the solar spectrum. The physical properties of the semiconductor materials in each cell allow one to absorb light at longer wavelengths and the other to absorb light at shorter wavelengths. Researchers have made tandem solar cells before, but the vapor-deposition methods used to produce the multilayer structure have made the cells relatively expensive. Jin Young Kim and colleagues now describe a cheaper method for making a tandem semiconducting polymer cell, in which all of the layers, including the electrode connecting the two units, are processed from solution. They used bulk heterojunction materials made from semiconducting polymers and fullerene derivatives. The cell’s efficiency exceeds 6 percent at illumination of 200 milliwatts per cm2, which is quite good for cells produced via an all-solution method. Reference: “Efficient Tandem

Lately, I have been all about polymer clay jewelry. I think it is so cool how jewelry, wall art, and other functional objects can be made from clay. The closest I have come to using clay is making some really fun stuff with Play Dough. Oh wait...not exactly the same thing is it? At any rate, I just learned that the Polymer Clay Artists Guild of Etsy (PCAGOE) , a global group of artists working in polymer clay, has a fabulous monthly challenge and giveaway. This month, there are three incredible polymer prize packs valued at over $50 each (see pictures below!) Simply check out their site HERE and vote for your favorite entry.

Researchers are working on a polymer gel that when rubbed around the vaginal area will createa thin protective layer, similar to that of a condom.  The difference is that when semen comes in contact with this polymer gel a lethal dose (to the HIV virus) of chemicals is released.  As of now this technology is still years in the making but is showing pretty decent results.  Researchers say the gel will more than likely not be 100 percent effective, but the goal is to have it prove over 90 percent effective.  The best part about this technology is that it gives women the means of protecting themselves instead of always having to rely on their partner.  However, for now the condom is still the most successful at protecting against HIV/AIDS.  Also, if these results are successful then researchers say it is possible to use the same concept to help protect against pregnancy.  more info >>

There are a number of well known PE polymerization licenses which are applied in 80 percent of the world's PE Base Resin production lines. The main licenses are Unipol, Himont and Borstar. In each case there is a continuous stream of PE powder (fluff) being produced, which must be pelletized. It is in this pelletizing process that K-Tron feeders play a key role in metering the PE powder being fed into the compounder for pelletizing. The main component is PE Base Resin Powder and the additives...

What is a polymer?Plastics are polymers. The simplest polymer definition is something made of many units. Think of a polymer as a chain. Each link of the chain is the "-mer" or basic unit that is usually made of carbon, hydrogen, oxygen, and/or silicon. To make the chain, many links or "-mers" are hooked or polymerized together. Polymerization can be demonstrated by linking countless strips of construction paper together to make paper garlands or hooking together hundreds of paper clips to form...
