Research uncovers path to defect-free thin films

ScienceDaily (Sep. 20, 2012) ? A team led by Oak Ridge National Laboratory's Ho Nyung Lee has discovered a strain relaxation phenomenon in cobaltites that has eluded researchers for decades and may lead to advances in fuel cells, magnetic sensors and a host of energy-related materials.

The finding, published in Nano Letters, could change the conventional wisdom that accommodating the strain inherent during the formation of epitaxial thin films necessarily involves structural defects, said Lee, a member of the Department of Energy lab's Materials Science and Technology Division. Instead, the researchers found that some materials, in this case cobaltite, form structurally well ordered atomic patterns that can change their magnetic properties and effectively minimize the size mismatch with the crystalline substrate.

Epitaxial thin films, used in nanotechnology and semiconductor fabrication, are created by growing a crystal layer of one material on another in such a way that the crystalline structures align. The challenge is to grow the film coherently with minimal defects, which can have a catastrophic effect on a material's performance.

"We discovered properties that were not readily apparent in crystal, or bulk, form, but in thin-film form we were able to clearly see the atomically ordered lattice structure of lanthanum cobaltite," Lee said. "With this knowledge, we hope to be able to tailor the physical properties of a material for many information and energy technologies."

The researchers studied the material in different strain states using scanning transmission electron microscopy complemented by X-ray and optical spectroscopy. Using these instruments, the scientists could see unconventional strain relaxation behavior that produced stripe-like lattice patterns. The result is a material with useful magnetic properties and highly suitable for sensors and ionic conductors used in, for example, batteries.

This discovery and the ability to engineer the structure of materials could lead to advanced cathode materials in solid oxide fuel cells and batteries that can be charged much faster.

"Since cobaltites are promising candidates for magnetic sensors, ionic conductors and surface catalysts, this discovery provides a new understanding that can be used for artificial tuning of magnetism and ionic activities," Lee said.

Mom: Substitute teacher duct-taped kid's mouth shut

By NBC News staff

A mother in Louisiana is pursuing legal action against a substitute teacher she says put duct tape across her child?s mouth.

Michelle Droody says it took her a week to figure out why her nine-year-old son, a student at J. Wallace James Elementary School in Lafayette, La., was so upset.

?He just told me he didn?t want to go back to school no more,? Wallace told KATC TV in Lafayette. ?And he didn?t want to be friends with anybody in his class or school.?

Only after school officials interviewed about 100 students did Droody learn that a substitute teacher used red duct tape, normally used for arts and crafts projects, to quiet her son.

Dr. Pat Cooper, Superintendent of Lafayette Parish Public Schools, confirmed the incident to KATC, which happened September 12, and said the substitute treated the student both ?outside the boundaries of [their] discipline matrix? and ?outside the boundaries of common sense.?

Cooper said the teacher had been disciplined.

?We fell like we?ve taken the necessary disciplinary action against that teacher, but the parent always has the right to take additional charges.

Droody said she intends to pursue further criminal charges.?

?Now he has to face these same kids for the rest of the year that were sitting there laughing at him, the embarrassment and the shame that goes along with having someone you?re supposed to respect that comes and duct tapes your mouth shut in front of everybody," Droody said.

Lafayette Police Department Public Information Officer Paul Mouton told NBC News police were contacted by the school, and a report has been filed and police are actively investigating the incident.

?If investigators determine that enough probable exists, the detective in charge will issue a warrant and have the substitute teacher arrested,? Mouton said. ?If there?s not enough cause, the case will be submitted for review.??

This isn't the first time a teacher has tried to quiet a student by using duct tape.?

A third-grade teacher in Albuquerque was placed on administrative leave last October for allegedly duct-taping the mouths of two students to keep them quiet. A first grade teacher in Massachusetts was fired after she duct-taped 20 students, although she insisted the duct tape was tied to a book her students read earlier in the year.?

iOS 6 now available, here's what you need to know

18 min.

As Apple promised it would be, iOS 6 is here.? We gave it ? and the 200 or so new features it brings ? a close look. Here's are the key things you need to know about the latest version of Apple's mobile operating system.

Can?your device handle iOS 6?

According to Apple, you should be able to run iOS 6 on an Phone 3GS, an?iPhone 4, an iPhone 4S, a?fourth-generation iPod Touch, an?iPad 2 or a?third-generation iPad.?Yes, this means that folks with older iPod Touch devices, the original iPhone, or the iPhone 3G are officially out of luck.

Now, that's the official word. But?it's worth noting that?? like some other updates?? this particular iOS version might leave some of the older supported device feeling a bit sluggish. Keep that in mind, especially if you're using an iPhone 3GS, which was already left feeling a bit slow after the jump to iOS 5.

What makes iOS 6 so much better than older versions of iOS?
There?are over 200 new features to be found in iOS 6, but?? as always?? some stand out. Here are the key changes to know.

Siri
Siri has gotten some significant improvements in iOS 6. She's learned a lot of new languages (Italian, Mandarin, Cantonese, and more) and become friends with a lot of new services (such as OpenTable, Yelp, Rotten Tomatoes, and others).

This means that you can now get way more information directly from the personal assistant instead of being told that she'll search the Web for you. Now Siri will provide you with sports scores, movie times, and detailed restaurant information. On top of that, she can even help you make restaurant reservations, tweet for you, and even launch apps.

While Siri still isn't perfect, these changes are rather great and make it more likely that you'll actually use Siri for certain task instead of just treating her as a joke generator.?

Although ... if you do use Siri to amuse yourself, you may be happy to know that she's picked up some more jokes since the last time we explored how she says the darndest things.

Passbook
A new app called Passbook can store many of the things which normally clutter up your pockets. Boarding passes, discount cards, movie tickets, gift certificates, and so on can be contained securely within Passbook.?

Since the app has location support, it will also pull up the relevant item when you are near the place in which you'd use it. This means that your Sephora loyalty card will be right on your screen as you reach for a new lipstick, your boarding pass will appear as you arrive at the airport, and your Starbucks card will pop up as soon as you smell the coffee beans.

Facebook
Like Twitter, Facebook is now deeply integrated into iOS. You can post directly to the social network using a "tap to post" button in the Notification Center, from the Photo Roll, and more. And to make your life easier ??in theory, anyway ??you can allow events and birthdays which are listed on Facebook to populate in the Calendar app.

Do Not Disturb
Words can barely convey how incredibly useful the "Do Not Disturb" mode found in iOS 6 is.?This little feature allows you to silence alerts and calls for a while in way?significantly?more clever than what's offered by the regular volume toggle.?

You can designate regular "quiet hours" during which Do Not Disturb mode will automatically kick in, you can choose to allow calls from people who are listed in your favorites or contacts to ring through, or you can tell your iPhone to ring if someone calls twice within three minutes.

Maps
Not everyone will like how the Maps app has changed in iOS 6.?Apple has ditched Google Maps and now uses its own mapping solution (which is powered by TomTom).?This means that the Maps app is a wee bit different. There's Yelp integration, traffic information based on crowd-sourced data, automatically re-adjusting routes, and turn-by-turn directions.?

Yes, you read that right. There are finally turn-by-turn directions directly in the Maps app. And they're rather solid. (If they manage to get someone as?? ahem?? lacking in navigational skills as yours truly somewhere, they'll get anyone where he or she needs to go.)

Oh! And?Apple also added something called "Flyover" to Maps. This feature makes the whole world look a bit like a Sim City game by showing 3-D models of geographical features and buildings.

There are naturally some downsides to the revamped Maps app, of course. Without Google's gigantic and well-established pile of data, the Maps app can occasionally fail to find certain points of interest, lacks detail at certain zoom levels, and lacks public transportation information. They're tolerable shortcomings, but the Wall Street Journal's Walt Mossberg went as far as calling them the?"biggest drawback" of the iPhone 5 (which ships with iOS 6) when he reviewed the device.

Privacy
The new "Privacy" menu in the iOS 6 settings will help you sleep far more soundly at night. It breaks down the various items to which an app might request access (Contacts, Photos, Location Services, etc) and allows you to toggle each app's access to the item on and off.

This is a great way to check whether you accidentally gave an app more information than you intended?? and to simply take back some control later down the line.

Reply With Message and Remind Me Later
Odds are that you'll occasionally find yourself in a situation which prevents you from answering a call which matters. It's inevitable. But with iOS 6 you at least have the option of quickly replying with a preset text message or setting a reminder to return the call at a later time.

You can do either of those things in about the same amount of time it would take you to swipe your finger across your iPhone's screen.

What do you need to do before upgrading your?device?to?iOS 6?
Before you try upgrading your device to iOS 6, you need to make sure you have the latest version of iTunes. After you've taken care of that, you should really consider backing up your device?? just in case something goes wrong.

All you need to do in order to back up an iPhone, iPad, or iPod Touch is connect it to your computer, open up iTunes, right-click the gadget in the "Devices" menu, and select the "Backup" option. The software will take care of the rest. Once the backup process is complete, feel free to tap the "Check for Updates" button to get the iOS 6 download started. iTunes will walk you through the rest of the upgrade process. (Alternatively, you can also just update your device "over the air" by opening up the Settings app, tapping on "General," and selecting "Software Update.")

Want more tech news?or interesting?links? You'll get plenty of both if you keep up with Rosa Golijan, the writer of this post, by following her on?Twitter, subscribing to her?Facebook?posts,?or circling her?on?Google+.

Auto loan calculator is essential for the almost all at the time of financing the vehicle by means of loan. The auto mortgage multiplier is needed to perform out the total sum benefit to be repay every thirty day period alongside with the fascination rate. The desire rate and the sum of the observe are determined with the assist of the Car mortgage . The sum for the duration of funding must be determined exact or it may turn around into defeat to either of the frequent assembly. The loan seeker before generating an agreement have to estimate the installment to be compensated every single thirty day period and the desire price on the sum of mortgage. The calculation has to be accurate to guarantee a very good bargain.

Pink on Miley Cyrus, Hair: Beautiful! Rockin!


Miley Cyrus may have received some flak for her apparent Pink impression at the MTV Video Music Awards, but there's one person who had no problem at all with the young singer's red carpet look:

Pink herself!

Alecia Moore PictureMiley Cyrus Blonde Hairstyle

“Everyone has long, brown hair,” Pink said yesterday morning during an appearance on Today. “When two girls get fearless and shave their heads, it’s a big deal. I think we’re just a little more daring.”

That isn't the reaction many have had toward Miley Cyrus' new hair, of course, but Pink dismisses the haters.

“I think she’s beautiful," the pop star said of her fellow artist. "I think she rocks it way harder than I do."

Roleplayers Needed For Facebook Roleplay?

Hey blackrose13. Just so you know, it's against the rules to use our forums to advertise for roleplays that take place off-site, rather than on RoleplayGateway. If you have a site you wish to advertise, you can do so in the Roleplay Directory.

That said, I've edited your topic title to reflect this. I've also moved it to the 'Interest Check' forum, because in consideration of what I'd said earlier, your roleplay does not exist yet.

It's pretty easy to create your own roleplay on site, in all actuality, and all it takes is a visit to this page (which can also be found by hovering over the 'Roleplay' tab).

All that said, I wish you luck in creating your roleplay. If you'd like, feel free to PM me (requires 10 posts, but it is preferrable) or reply in-thread, and I'll check back.

Cheers and happy trails,
