Lenovo says company may try to acquire RIM to boost mobile business
BlackBerryLenovo?(0992) may be the world?s second-largest PC vendor, but it knows that it desperately needs to step up its game in the mobile world to stay relevant. Bloomberg reports that Lenovo CFO?Wong Wai Ming told the World Economic Forum in Davos on Thursday that his company is looking at a variety of options to boost its mobile game, including buying BlackBerry manufacturer Research in Motion (RIMM).
[More from BGR: BlackBerry 10 said to be overhyped, RIM?s comeback chances remain slim]
?We are looking at all opportunities ? RIM and many others,? he said. ?We?ll have no hesitation if the right opportunity comes along that could benefit us and shareholders.?
[More from BGR: Apple: ?Bent, not broken?]
At first glance this idea seems to have some merit since RIM?s enterprise-centric smartphones would seem to be a good fit with Lenovo?s enterprise laptops and tablets. According to Bloomberg, Ming said that Lenovo already ?has a team working on possible acquisitions? that ?has spoken to RIM and its bankers about various combinations or strategic ventures.?
Ming wouldn?t say if the company planned to make a formal offer to buy RIM anytime soon.

Local woman and family attend inauguration - News - News Item
RIVERSIDE - If there's any word to sum up how Laurie Fitzpatrick felt when she watched the presidential inauguration Monday in person in the nation's capital, it's pride.
"It was so moving," the Riverside woman said Tuesday evening by telephone.
She, her husband, Matthew, their two children, 7-year-old Erin and 10-year-old Megan, and her mother-in-law, Linda, of New York, were approximately the length of a football field away from the stage between the Capitol and the reflecting pool where president Barack Obama was sworn in Monday. They were so far away, they watched the event via video screens.
"If you squinted really hard, you could see someone at the podium," Laurie joked.
The family of five was provided with tickets to the ceremony through state Rep. Lynda Schlegel Culver (R-108), who got the tickets from U.S. Rep. Lou Barletta (R-11).
Fitzpatrick said she and Culver went to high school together, and she helped the representative in her election campaigns. She also is involved in discussions about early childhood education issues and is the president of Home and School Organization at Danville Primary School.
Being interested in politics since President Bill Clinton was in office, Fitzpatrick said she was thrilled when Culver offered the tickets.
"I couldn't speak," she said, noting she initially only made hand motions to her husband when she got off the phone with Culver.
Dreams, rights
Two moments of Obama's inaugural address stuck out to Fitzpatrick: when the president said everyone, regardless of sexual orientation, should have equal rights under the eyes of the law, and when he commented on the American dream of immigrants.
"Living in the community near Danville, I see that a lot," she said, noting the many physicians who come from other countries to practice medicine at Geisinger Medical Center. "They wouldn't come here if it's not a better place to live, and train, and a better place to be."
Her mother-in-law is 70, and never went to Washington, D.C., before, Fitzpatrick said.
"She's not an Obama supporter, but she decided it was a once-in-a-lifetime event, to see democracy in action. She told me later she was so glad she went," she said.

Controlled crumpling of graphene forms artificial muscle
Jan. 23, 2013 ? Duke University engineers are layering atom-thick lattices of carbon with polymers to create unique materials with a broad range of applications, including artificial muscles.
The lattice, known as graphene, is made of pure carbon and appears under magnification like chicken wire. Because of its unique optical, electrical and mechanical properties, graphene is used in electronics, energy storage, composite materials and biomedicine.
However, graphene is extremely difficult to handle in that it easily "crumples," which, depending on circumstances, can be a positive or negative characteristic. Unfortunately, scientists have been unable to control the crumpling and unfolding of large-area graphene to take advantage of its properties.
Duke engineer Xuanhe Zhao, assistant professor in Duke's Pratt School of Engineering, likens the challenge of controlling graphene to the difference between unfolding paper and wet tissue.
"If you crumpled up normal paper, you can pretty easily flatten it out," Zhao said. "However, graphene is more like wet tissue paper. It is extremely thin and sticky and difficult to unfold once crumpled. We have developed a method to solve this problem and control the crumpling and unfolding of large-area graphene films."
The Duke engineers attached the graphene on a rubber film that had been pre-stretched multiple times of its original size. Once the pre-stretch in the rubber film was relaxed, part of the graphene detached from the rubber while other part kept adhering on the rubber, forming an attached-detached pattern with a size of a few nanometers. As the rubber was relaxed, the detached graphene was compressed to crumple. Once the rubber film was stretched back, the adhered graphene will pull on the crumpled graphene to unfold it.
"In this way, the crumpling and unfolding of large-area atomic-thick graphene can be controlled by simply stretching and relaxing a rubber film, even by hand," Zhao said.
The results were published online in the journal Nature Materials.
"Our approach has opened avenues to exploit unprecedented properties and functions of graphene," said Jianfeng Zang, a postdoctoral fellow in Zhao's group and the first author of the paper. "For example, we can tune the graphene from being transparent to opaque by crumpling it, and tune it back by unfolding it."
In addition, the Duke engineers layered the graphene with different polymer films to make a "soft" material that can act like muscle tissues by contracting and expanding on demand. When electricity is applied to the graphene, the artificial muscle expands in area; when the electricity is cut off, it relaxes. Varying the voltage controls the degree of contraction and relaxation, giving actuation strains over 100 percent.
"Indeed, the crumpling and unfolding of graphene allows large deformation of the artificial muscle." Zang said.
"New artificial muscles are enabling diverse technologies ranging from robotics and drug delivery to energy harvesting and storage," Zhao said. "In particular, they promise to greatly improve the quality of life for millions of disabled people by providing affordable devices such as lightweight prostheses and full-page Braille displays. The broad impact of new artificial muscles is potentially analogous to the impact of piezoelectric materials on the global society."
Zhao's work is supported by the National Science Foundation's (NSF) Triangle Materials Research Science and Engineering Center, NSF Materials and Surface Engineering program, and National Institutes of Health (NIH). Other members of the team are Duke's Qiming Wang and Qing Tu.
