Even though Christmas is more than 7 months away, and is one of the furthest things from most Long Islanders" minds, but this cold and dreary weather this week has me thinking of happier times while wearing a sweater...
If you want to splurge on your date night why not give one of the dinner cruise lines a call. Most dinner cruises are not crowded and give great sex appeal as you drift off away from a brightly lit city. Often they have wonderful bands and dancing goes on for three hours.
During the month of April, music lovers will also be treated to an eclectic mix of concerts, festivals and parties ranging from jazz to electronica to indie rock. Signature festivals include The Dinah, Palm Springs Women"s Jazz Festival, Opera in the Park, Coachella Valley festival wristbands, Stagecoach Country festival wristbands, and Brew at the Zoo.
KEN STRINGFELLOW: I would have it sell a bajillion copies, like, tomorrow. I know it"s a great album but I also event wristbands know we"ll have to work hard to convince people it"s something to listen to. We"re not the latest, shiniest flavor. But we"re the tastiest. This I know!
Saturday"s festival is geared toward the whole family and admission sport wristbands is free for all Celebrate Downtown C"Mon will be held at th Maine in downtown Tulsa. Musical talent will include Mary Cogan, Rochelle Chambers, David Skinner Band, WallStreet, Eldredge Jackson, and Jeff Shadley Group.
You will find all the Disney Characters in their festive attire for the party (think loud holiday sweaters), as well as many party goers! There will be many more characters out to meet, greet, and take pictures and for autographs. You can expect to see all of the major Disney characters as well as Santa Claus, Mrs. Claus, Scrooge McDuck- who is extremely rare during the rest of the year!
Billy Draws Two will be opening for Queensyryche, a heavy metal band formed in 1981 in Belleview, Washington, on July 31 at the Canal Fest Concert Series in Lockport, N.Y.
WASHINGTON - A team of Chinese scientists has used graphene to create an artificial gas detector that is as good as a dog"s nose.
The study, reported Wednesday in ACS Nano, a monthly scientific journal of the American Chemical Society, showed that the graphene-based nanoscrolls can mimic a dog"s sensitive sniffer, which is lined with millions of tiny capillaries.
It is well known that dogs have a better sense of smell than humans. For years, scientists have been trying to develop an artificial detector that is just as good as a canine"s nose.
Drawing inspiration from the capillary structure, researchers from South China Normal University and Beihang University found a way to modify the graphene with a polymer to make high-quality nanoscrolls.
These nanoscrolls have a large surface area like that in dog"s nose. They are stable at high temperatures, and are strong and durable.
Previous studies have produced the graphene-based nanoscrolls, which are nanosheets of graphene rolled up in continuous and uniform manner.
But they are difficult to manufacture, consume a lot of energy and difficult to scale up.
And past studies have used raw graphene or modified graphene that either left behind some unrolled structures, or shriveled up and aggregated, respectively.
The team prepared graphene-based nanoscrolls with the addition of poly or sodium-p-stryrenesulfonate, using the freeze-drying method to create uniform, unaggregated structures.
It showed that the nanoscrolls had a wide, tubular shape, and almost all of the graphene was rolled up.
The researchers then incorporated the nanoscrolls into a gas sensor, which was highly selective and sensitive.
They said that this method had the potential for large-scale production.
