(Phys.org) —In the growing area of flexible, transparent electronic devices, silicon has not played much of a role. Instead, materials such as indium tin oxide, carbon nanotubes, and others are often used to make bendable electronics.

Now in a new study, researchers have synthesized silicon nanowires and woven them into a paper that outperforms many other paper-like materials in terms of transparency and flexibility. Since today's integrated circuit technology is designed for silicon (in bulk form), silicon nanowires would be much more compatible with these existing technologies than other materials, an advantage that could potentially rejuvenate research into silicon-based flexible electronics.

The researchers, Chunlei Pang, Hao Cui, Guowei Yang, and Chengxin Wang, at F2080 in Guangzhou, China, have published their study on the flexible, transparent, and self-standing silicon nanowires paper (FTS-SiNWsP) in a recent issue of Nano Letters.

As the researchers explain, bulk silicon is brittle at room temperature and only becomes ductile close to its melting temperature of about 1400 °C. In contrast, nanoscale silicon possesses a very large straining ability that enables flexibility at room temperature. However, weaving silicon nanowires into a paper-like material has been challenging because it requires achieving a unique interlocking alignment using controlled, catalyst-free growth methods.

Here, the researchers developed a simple method to synthesize silicon nanowires and assemble them into the desired interlocking alignment using a vertical high-frequency induction furnace. SiO powder and Ar gas (serving as a carrier gas) get blown into the furnace where they are quickly heated to about 1600 °C and kept there for 1 hour. The heat causes the SiO powder to decompose into SiO2 vapor and Si particles, both of which are transported by the Ar gas to a low-temperature zone where they stratify under gravity action due to their different molecular weights.

As more SiO2 and Si are transported to their locations, they nucleate and grow. While the SiO2 deposits form a powder sample, the Si particles form nanowires with diameters of about 10 nm that grow in the direction of the gas flow. As the Si nanowires grow, they spontaneously interlock with each other to form a free-standing membrane material. Scanning electron microscope images show a highly porous, woven structure, whose pores can potentially be filled with other functional materials for novel applications. Tests also showed that the FTS-SiNWsP material had very good optical transmittance and could bend repeatedly without cracking.

To demonstrate how these woven silicon nanowires can be used to create high-performance battery electrodes, the researchers grew graphene on the outside of the silicon nanowires in a core-shell design. The graphene also filled the gaps of the woven silicon nanowire material, completely encasing the material. After fabricating coin-cell Li-ion batteries using a FTS-SiNWsP@graphene film as the anode and Li as the cathode, the researchers showed that these batteries have very good performance, performing close to their theoretical capacity and maintaining a capacity of more than 1000 mAh/g after 100 cycles.

The FTS-SiNWsP material has the potential for many applications in addition to battery electrodes, such as flexible solar cells, wearable computers, paper displays, and supercapacitors. In the future, the researchers plan to build on this synthesis method to develop silicon nanowire paper materials to meet these emerging technological demands.

Next, we plan to carry out the application research of the silicon paper material in solar cells, Wang said.

中国新航母上电磁弹射:世界最大功率超电容交付

junshi.xilu.com
2013-09-15

手机充电仅需2秒钟、储能式轻轨列车充电仅需20馀秒钟就能满足正常运用,这就是超级电容的神奇功能。如今,中国已牢牢占据这一世界前沿技术的高地。

9月12日,记者从中国南车株机公司了解到,公司旗下宁波南车新能源科技有限公司自主研制的世界最大功率超级电容单体(7500F)成功实现了批量生产,首批5000只7500F超级电容产品已交付用户。

世界最大功率超电容单体交付
Delivery of the world's largest supercapacitor


  何为超级电容?中国工程院院士、中国南车株机公司专家委员会主任刘友梅告诉记者,通俗地讲就是第三代储能装置,第一代为机械式储能,如飞轮、发条等;第二代为化学式储能,如铅酸蓄电池、镍氢电池、锂电池等;而第三代就是以超级电容为代表的物理式储能装置。

  “充电次数10000次以内、充电时间长达数小时、存在爆炸与污染环境的风险”VS“100万次、数十秒、无污染以及爆炸风险”。

  中国南车株机公司技术中心副总监、宁波超级电容研究所所长阮殿波用一组对比形象地展示了超级电容较之传统化学能电池的优势。

  这种产品其应用范围有哪些?据阮殿波透露,其可广泛运用于消费电子、轨道交通、城市公交系统、国防与航天、起重机械势能回收、发电与智能电网等领域。

  阮殿波举例说,比如目前港口的起重吊机,其一次吊起上百吨的货柜要消耗大量的电能,而其在落下时的能量基本被电阻装置等消耗掉,如果采用超级电容进行势能转换电能的回收,约可实现高达80%的电能回收再利用,其绿色、节能、环保的成效相当突出。

  正是鉴于超级电容卓越的绿色、节能、环保优势,近年来,韩国、美国、日本等国就超级电容已开展了大量研究工作,目前全球已有十几家超级电容器生产商,可以提供多种类的超级电容产品。

  我国从上世纪90年代开始研制超级电容,近年来以中国南车为代表的企业在超级电容的结构设计、材料制备、器件加工、系统集成等领域取得了系列发明和创新,并拥有自主知识产权,突破了若干制约超级电容技术发展的关键瓶颈,打破了国外技术封锁,使我国成为世界上少数具有大功率超级电容研发能力的国家。

  阮殿波告诉记者,正是得益于我国在超级电容研制领域的突破,为我国下游相关领域产品的创新及运用提供了“芯”的保障,比如中国南车株机公司去年下线的世界首台储能式轻轨列车,其就装有上千个3000F的超级电容单体,其一次充电20馀秒后,可运行3公里以上,并能在运行中将制动能转化成电能循环利用,实现城区内的绿色、智能出行。

  目前,国内多个城市正与中国南车株机公司开展沟通与交流,开发运用以超级电容为主动力源的100%低地板有轨电车、城市公交车辆等绿色智能产品。

  鉴于超级电容的应用价值,由中国南车株机公司牵头,中国科学院青岛生物能源与过程研究所、中国工程物理研究院化工材料研究所、南京理工大学等单位共同参与的“高比能、低成本的新型超级电容器关键技术研究”,作为高性能化学储能电池及示范电站关键技术研究主题项目的子课题,参与国家“863”计划。

Chinese researchers find low cost method to produce ethylene from ethanol
Meghan Sapp | August 5, 2013

http://www.biofuelsdigest.com

In China, researchers from Tianjin University Research and Development Center for Petrochemical Technology found that one particular device has the potential to make a highly pure ethylene product from ethanol with high efficiency and low cost. The device, called a fluidized bed reactor, works by suspending the chemicals needed to make ethylene inside the walls of a chamber. Newly produced ethylene exits through a pipe, while the rest of the material remains to continue production

Ethanol from corn and other plants could become the sustainable, raw material for a huge variety of products, from plastic packaging to detergents to synthetic rubber, that are currently petroleum-based. This was the conclusion of an article published in the ACS journal Industrial & Engineering Chemistry Research.

Yingzhe Yu and colleagues point out that a chemical called ethylene, now produced from petroleum, is one of the most important raw materials for everyday products. Ethylene is used to make hundreds of products, including polyethylene, the world’s most widely used plastic. Scientists have been seeking sustainable alternatives to petroleum for making ethylene, and Yu’s team reviewed progress in the field.

They found that one particular device has the potential to make a highly pure ethylene product from ethanol with high efficiency and low cost. The device, called a fluidized bed reactor, works by suspending the chemicals needed to make ethylene inside the walls of a chamber. Newly produced ethylene exits through a pipe, while the rest of the material remains to continue production. Yu’s team discusses progress toward commercial use of such devices, noting that there would be “great significance” for promoting economic development.

Abstract

This article is an up-to-date review of the literature available on the subject of ethanol to ethylene. The process of ethanol to ethylene has broad development prospects. Compared with the process of petroleum to ethylene, ethanol dehydration to ethylene is economically feasible. Researchers have been redirecting their interest to the ethylene production process, catalysts, and reaction mechanisms.

A fluidized bed reactor, together with a wear-resistant, efficient, and stable catalyst will be the focus of future research that includes a deep understanding of the large-scale activated alumina catalyst and the molecular sieve catalyst used, and will promote the development of the ethanol dehydration to ethylene process and provide strong support for the market competiveness of the process.

TAIPEI, Taiwan -- The Chinatrust Charity Foundation (中國信託慈善基金會) yesterday announced its collaboration with the China National Committee for the Wellbeing of the Youth (CNCWY, 中國關心下一代委員會) and mainland China's Ministry of Civil Affairs' Foundation for the Next Generation (中國社會福利基金會關心下一代基金) in establishing education demonstration zones in mainland China.

Known for its annual “Light Up a Light” fundraisers and programs with an aim to fight poverty in disadvantaged Taiwanese families, Chinatrust will be expanding its charity programs to the other side of the Taiwan Strait, looking to improve the educational resources for children living in China's less-developed regions.

The three organizations aim to establish 30 demonstration zones in China over the next six years, not only to improve the environment of local schools in impoverished areas, but also to raise the standards of teachers employed at the targeted institutions.

Ku Hsiu-lien (顧秀蓮), head of the CNCWY, presented Chinatrust Chairman Jeffrey Koo Jr. with a “Special Contribution Award,”acknowledging his past efforts in assisting disadvantaged children and families.

The two Chinese organizations held a charity fundraiser last Wednesday, with Chinatrust Vice Chairman Thomas KS Chen (陳國世), Kuomintang Vice Chairman Chiang Pin-kung (江丙坤), soccer star Luis Figo and former Real Madrid team members attending.

Hmong (苗族) children from Fenghuang County, Hunan Province performed traditional tribal dances at the fundraiser to express their gratitude to the CNCWY and the Foundation for the Next Generation.

Chen bid for Chinese artist Chen Guang-wen's (陳廣文) painting on Koo's behalf in the hope of encouraging the guests to begin bidding in order to help Chinese students in need.

“I hope the Real Madrid team members will be able to travel to China in the future and give free soccer lessons for the disadvantaged students,” said Chen.

Robots May Revolutionize China's Electronics Manufacturing - WSJ.com

A new worker's revolution is rising in China and it doesn't involve humans.

With soaring wages and an aging population, electronics factory managers say the day is approaching when robotic workers will replace people on the Chinese factory floor.

A new wave of industrial robots is in development, ranging from high-end humanoid machines with vision, touch and even learning capabilities, to low-cost robots vying to undercut China's minimum wage.

Over the next five years these technologies will transform China's factories, executives say, and also fill a growing labor shortage as the country's youth become increasingly unwilling to perform manual labor. How the transformation plays out will also go a long way in deciding how much of the electronics supply chain remains in China.

It's not just traditional robot makers like Zurich-based ABB GroupABBN.VX +0.46% and Germany's Kuka AG KU2.XE +1.82% pushing forward. Electronics suppliers in Asia such as Delta Electronics Inc. 2308.TW +0.69% and Foxconn Technology Group2354.TW +0.65% are also seeking to build a better robot, along with smaller players like Denmark's Universal Robots A/S.

But some industry executives caution that China's automation shift will likely take years and there are plenty of challenges, including the high price of advanced robots, continuing technical limitations and even the lack of flexibility that comes with bringing robots into the factory.

"If your orders decrease, you can lay off workers," said Tim Li, senior vice president of Taiwanese PC contract manufacturer Quanta Computer Inc. "You can't lay off robots."

One of the newest companies in this field, Taiwanese firm Delta, has long made power adapters for brands like Apple Inc., AAPL -0.31% but last year it began a more ambitious project: to build robots cheap enough to replace human workers in China's electronics factories.

"It's clear that automation is the future trend in China, but the big question is how to bring down the costs for robots," said Delta Chairman Yancey Hai in an interview. "We believe we can do that because we manufacture two-thirds of the components ourselves."

Delta is testing a one-armed, four-jointed robot that can move objects, join components and complete similar tasks. By 2016, Delta hopes to sell a version for as little as $10,000, which would be less than half the cost of current mainstream robots.

That price is also cheaper than the salary of a Chinese worker, and the robot can work around the clock.

Delta believes it can achieve the low price through cost advantages at its Taiwan facility, in-house component production and a shorter target life span for its robot.

Outside Taiwan, there are also more futuristic robots in the works designed to be easily reprogrammable and smart enough to work alongside humans without risk of injury. For instance, ABB's concept humanoid robot has two 7-jointed arms that perform precise tasks and halt when touched by a person.

These robots are more expensive than factory workers, but the cost gap is shrinking, with China's wages rising by a double-digit percentage annually.

The advancements in robotics has led to hopes that electronics firms will bring some manufacturing back to the U.S. But industry followers say electronics assembly is likely to stay in China even as automation becomes easier because the larger component supply chain is in the country.

To be sure, robots have long been technically capable of the tasks required for final assembly: placing components on circuit boards, affixing circuit boards into casings, screwing together the casings and cleaning off the devices.

But human hands are still considerably cheaper for such jobs in China. People are also better at switching tasks than a robot, which requires reprogramming.

There are also logistical obstacles to automation.

Because of the short sales cycle of electronic devices, products are only in production for around 9 to 18 months, with production settings requiring change afterward, said ABB China Senior Vice President Chun-yuan Gu.

"There's a fast ramp up and a fast ramp down, and that is the key challenge," he said.

Even Foxconn, the industry's loudest proponent of automation, continues to rely on city-sized factories where more than 1.1 million workers do the bulk of the assembly of iPhones and other devices by hand. Foxconn originally planned to install 1 million robotic arms in its factories by 2014, but executives said it would take much longer to reach that target.

Automation would help companies like Foxconn that are continually beset by criticism over worker conditions. Indeed, Pegatron Corp., 4938.TW +1.50% another Apple supplier that makes iPhones, was recently accused by New York-based nonprofit organization China Labor Watch for alleged labor rights violations.

The Taiwanese company is focusing its automation efforts on the most dangerous and laborious tasks, said Chief Financial Officer Charles Lin.

Pegatron has invested around $100 million in the past year to automate production of electronic device casings, which involves harsh chemicals.

Quanta, the world's largest PC contract manufacturer, expects to make a massive automation shift in "the next two years or so" as labor costs rise, said Chief Financial Officer Elton Yang.

For robot makers like Kuka, that spells opportunity.

"Twenty percent of our business is in China and we see that rising," said Kuka Chief Executive Till Reuter. He said Kuka is investing in a new Chinese factory that can churn out at least 5,000 more robots a year from 1,500 to 2,000 currently.

Universal Robots and ABB also said they're boosting their China investment, and with good cause: China's industrial robot shipments will rise to 35,000 units in 2015 from 26,000 in 2012, the largest increase of any country, according to estimates from the International Federation of Robotics. While robots are used in many different types of factories in China, analysts and robotics companies point out growing demand to automate the electronics supply chain is giving demand a decided boost.

Kuka's Mr. Reuter says it's easy to see how robots can give factories a helping hand. "We have industrial robots…which we work 24 hours a day, seven days a week for seven to 10 years," he said.
