Chinese researchers turn industrial waste gas into remagic wristbandssin lens2010 Chicago Music Festivals - Something For Everyone It"s that time of year again. As spring settles in (albeit slowly), the summer music festival season in Denver is hard on its heels. We"ll be giving you a heads-up about some of these events as they approach-and we"ll start with the annual Westword Music Showcase, to be held June 22, 2013. What if another 9/11 event wristbands occurs? Will it be said it happened on Obama"s watch? Will he be blamed for things out of his control? What if President Obama follows UN direction and uses force in Darfur, or Somalia? Only time will tell, my friends. Trade indexes not individual stocks - Indexes generally have much lower volatility than individual stocks and for this reason, I rarely use this strategy on individual stocks. Using FFIV as a recent example, on one particular day, there was a negative news report and the stock dropped about 20%. While possible, it is incredibly rare that you would see an index fall by this much in a single day, but it occurs more regularly with individual stocks especially tech or small caps stocks. The bid-ask spread is also lower for indexes meaning you sport wristbands are not suffering a liquidity premium. Cold Souls: Rated for PG-13 for nudity and brief strong language. 97 mins. Full of angst, Paul Giamatti finds his solution in a company that promises to remove all stress, fear and worry by deep-freezing the soul and allowing customers to live angst-free. Giamatti"s soul is stolen and sold on black market to a Russian soap opera actress. In order to retrieve his soul, he must make his way to St. Petersberg and learn the real meaning of life along the way. Head to the beach. Many families say good-bye to summer by spending Labor Day weekend at Virginia Beach. The Verizon Wireless American festival wristbands will entertain people of all ages with oceanfront concerts, food and fun. Shows cost anywhere for $5 to $12, depending on whether an out-of-town group is playing, how popular the bands are, etc. If it"s a pretty big show, you can save a couple bucks by purchasing tickets online in advance. Some of the shows are all ages but, unfortunately, quite a few require attendees to be at least 21 years old. You can check their online calendar for specifics. Fishing is another popular pastime in Lorne. Beach fishing can be good but most anglers seem to prefer the Lorne pier where you can catch just about anything. Whiting and Flathead are a common catch and in winter you can get on to a school of Snapper. Squid can also be caught by jigging at the end of the pier. If you don"t have any luck there is no need to worry because the local fishing co-op is right near the pier and they do very good fish and chips. Wherever your Labor Day weekend plans take you, be careful on the road. Holiday traffic will be heavy and there"s construction around town and across the state.
BEIJING - Using a metal-free catalyst, Chinese researchers have turned industrial waste gas into a solid and transparent material that can be developed into resin lens, Science and Technology Daily reported Monday.
Carbonyl sulfide is the most abundant sulfur-containing gas generated by coal power plants and oil refineries. It can corrode buildings, cause haze and acid rain, and damage human health by causing diseases.
The gas can also destroy the ozone layer.
Researchers at Zhejiang University placed the gas in an autoclave with epoxide, a common chemical material, and a metal-free catalyst. These chemicals reacted and formed a polymer, a macromolecular compound which is colorless, transparent, and innoxious.
Further study showed that the polymer performed as ideal resin lens, and could be manufactured into glasses or optical fibers.
Zhang Xinghong, lead researcher on the study, said the key to the research was the development of the metal-free catalyst, which made the catalysis more simple, inexpensive, and effective than using a catalyst containing heavy metals.
The research, published in the journal Nature Communications, may contribute to the waste gas recovery and utilization.
