The bus stop legacy… innovation + people power

How to Spread a Small Idea Into a Big Deal: Bus Stop Libraries

By Shlomo Maital
  I love public transportation, and ride Israel’s excellent trains and buses all the time.  Lately, at several bus stops, I noticed something rather strange.  There were improvised book shelves, and books on them.  Why? Who?  When? 
   I discovered the answer the other day. Here is the story.   Dr. Danny Shoshan, and Amit Matalon, of Technion’s Architecture Faculty, devised an experiment to see how the city and its residents interact.  They placed two sets of bookshelves at bus stops in a Haifa neighborhood.  They stocked them with books and monitored what happened over a 3-week period.  “A miracle took place,” Shoshan says. “People took over the role of stocking and returning the books”.  They then expanded the project to six more locations.  The same thing happened.  Technion students began to put their theses and textbooks on the shelves for sharing.  In religious Orthodox neighborhoods, residents put religious books and CD’s on the shelves.  
  “Our motivation for the project was art,” Shoshan says. “Public space is the place to bring Art!”  Similar “libraries” have been built in other Israeli cities – Tirat HaCarmel, Kfar Saba and even Tel Aviv.  Others will soon be added.  There have even been orders from abroad.  The Mayor of Kfar Saba notes, “with minimal investment and very very creative thinking, we can make municipal libraries available to the general public.”  
    Innovator – why not try this in your city?  Just put a few books on the bench at a bus stop.  See what happens.  Or in general:  Put something in a public place, that arouses curiosity, interaction and conversations.  This is what ‘art’ is truly meant to be.

Going public takes on a whole new meaning as researchers from Technion’s Faculty of Architecture and Town Planning establish ad hoc micro lending libraries at local bus stops. Dr Danny Shoshan, senior teaching associate at the Faculty, and Amit Matalon, final year architecture student, devised the public library as an art experiment in the urban landscape, to see how the city and its residents interact.

First, they placed two sets of bookshelves at bus shelters in the Ziv neighborhood of Haifa, near the Technion, stocked them with books and monitored what happened over a 3-week period. “After some time, a miracle took place,” says Shoshan. “People took over the role of stocking and returning the books.”

Next, the urban researchers expanded the project to six locations including the Technion campus. “We saw that Technion students began to put their theses and textbooks on the shelves for sharing,” Shoshan explains. “In the ultra-Orthodox section of the neighborhood, the residents brought religious books and even CDs with religious content.” Matalon says, “It’s important to note that our motivation for the project was Art. Public space is the place to bring Art.”

Shoshan and Matalon continue to check that the shelves remain stocked and observe different urban settings with diverse responses on the part of the citizens and the authorities. “The passive ‘viewer’ becomes involved in the process and turns into an active ‘user’ of this urban art form,” they note.

Similar libraries were built in Tirat HaCarmel, Kfar Saba and Tel Aviv. Other cities will soon be added. “We have also had orders from abroad,” Shoshan reveals. Mayor of Kfar Saba, Yehuda Ben Hemo, said, “With minimal investment and very, very creative thinking, we can make municipal libraries accessible to the general public.”

“This project is really going viral! It works, it’s successful, and it creates additional facilities within the existing urban framework,” Shoshan explains



Kfar Saba presents: Bus stop libraries

At this library there are no librarians urging visitors to be quiet, and no one will try to convince you to take “War and Peace”. At this Kfar Saba library you’ll mainly find noisy buses, a busy street and the smell of cigarette smoke – all fitting the first library in Israel located at a bus stop.

Several weeks ago the Kfar Saba Municipality set up libraries along Weizmann Street, on both sides of the road, in the least expected place. Shelves installed on the bus stops’ walls were filled with books in different languages, of various genres, including cookbooks and poetry collections.

Passengers may borrow a book while waiting for the bus, read it during the ride, and return it wherever they get off. Those who would like to finish reading the book may take it home and return it several days later.

“Residents here are deeply rooted and take an interest in culture,” says Kfar Saba Mayor Yehuda Ben-Hamo. “In order to meet the residents’ needs, we have launched an initiative making books more accessible to our residents and encouraging them to use public transportation as part of the agenda of a healthy and green city.”

The project was initiated by Daniel Shushan and Amir Matalon, a graduate of the Technion’s Faculty of Architecture, two urban artists who suggested the idea to the mayor with the aim of giving the city’s residents access to books.

Residents are invited to add their own books, the municipal library fills the shelves on a daily basis, and at this stage the municipality has decided not to keep records of those who borrow the books or check whether they are returned.

“At first we asked ourselves how long it would last,” says Ossi, a city resident. “But then we decided to get rid of the negative thoughts because this is a good thing which has proved itself after only one week. At the beginning of the week the shelf was full of books, throughout the week they disappeared, and suddenly there are new books.”

Haredi get High-tech – a positive process in education.

Technion launches engineering program for ultra-Orthodox sector



30 Nov 2011
Graduates will earn a bachelor’s degree along with an accredited surveyor’s license and a guaranteed job.

“I wanted to find a way to earn a living,” says Judah (not his real name), a 30-year-old ultra-Orthodox father of three who is studying civil engineering at theTechnion-Israel Institute of Technology in Haifa.
This may sound like a simple and obvious desire. But ultra-Orthodox (“haredi”) schoolboys receive an education focused solely on Jewish holy texts. Therefore, thousands of able-bodied young men are ill-equipped for the job market and have few options aside from fulltime Torah study.
In this bleak situation, the Technion saw the potential for a win-win proposition, says Prof. Arnon Bentur, dean of civil and environmental engineering. “There is a need for professionals in technological fields, and the haredi population needs jobs. We can train them to have marketable skills for a workplace that needs them.”  (More than 25 percent of Israel’s first-year schoolchildren are ultra-Orthodox.)
Several years ago, the prestigious institute began offering an 18-month pre-academic crash course to haredi men to get their core science and math skills up to speed. Graduates who qualify can then go on to regular programs at the Technion, as Judah did. “I wasn’t sure what I was getting into, but I found I loved math, physics and science,” he says, estimating that he began at a sixth-grade level. Now he’s in his last year of undergrad studies and wants to continue on for a master’s degree.
However, his family is unhappy with his path because it necessitated not only leaving the study hall but also moving out of the ultra-Orthodox community into the more secular Haifa region. Understandably, few haredi men are willing to do so, and that limits severely the number of potential students in the program. And that’s why this fall, the institute has launched a new 15-month pre-academic course in the haredi enclave of Bnei Brak outside Tel Aviv.
Studying where they live
“We concluded that if we want to turn around the situation, the place where they study should be close to where they live, because for cultural and family reasons it’s difficult to get them away from their communities,” says Bentur. “Even just going to study in an academic institution is breaking a barrier for them, and it’s much harder if they have to move.”
The Technion’s Faculty of Civil and Environmental Engineering set up its new program at the Haredi College in Bnei Brak, a venture of the Israel Council on Higher Education that provides classrooms and administrative infrastructure to bring outside academic programs to the ultra-Orthodox world. Some of the classes will be taught via remote learning.
The three-year degree program following the pre-academic course is based on a unique partnership with the Israeli Mapping Center, a government institution. Graduates will earn a Technion bachelor’s degree in mapping and geoinformation along with an accredited surveyor’s license and the guarantee of a job with the Israeli Mapping Center. This marks the first time an applied engineering degree is being offered through the Haredi College, and it’s especially significant since the Technion is consistently ranked among the world’s leading science and technology universities.
Though the existing pre-academic program has shown that haredi men can learn core subjects quickly and successfully, not all of the 90 or so participants in the new pre-academic course will get high enough scores for acceptance into the three-year program in January 2013. “We hope for 25 to make it to Technion standards, and the rest could go on to other [college] programs,” says Bentur, who adds that ultra-Orthodox students “know how to learn and put a value on education.”
Student recruiting is done through the unit for ultra-Orthodox projects of theJoint Distribution Committee-Israel, as well as the Haredi College. The Technion is working toward raising sufficient scholarship money so that participants can have tuition covered as well as basic living expenses for their families as they earn their degree. “By following these core studies with education for a profession, we will boost Israel’s technological sector,” Bentur says.
Program organizers also expect that once they enter the workforce, graduates will serve as role models demonstrating that there need not be a contradiction between participation in the workforce and the ultra-Orthodox way of life.

Cornell – Technion – Together in Vision

Cornell, Technion share innovation and ‘land grant’ vision

Albert Einstein, center, visits The Technion in 1923. During his visit, he planted a now-famous first palm tree that still stands in front of the old Technion building in Hadar.
It should not be a surprise that Cornell and The Technion — Israel Institute of Technology have formed a partnership to propose building a new campus in New York City focused on technology, innovation and commercialization. A web of collaborative research and a shared mission have been connecting them for at least two decades.
“They are two institutions that are land-grant to the world,” said Carol Epstein ’61, a member of the Cornell University Council who also sits on the International Board of Governors of the Technion and the National Board of Directors of the American Technion Society. Epstein cited President David Skorton’s 2007 State of the University address: “We are … dedicated to applying the fruits of our research and teaching to help solve the world’s problems.”
As New York’s land-grant university, Cornell was created to advance the state’s agriculture and technology as well as to teach and make contributions in all fields of knowledge, and it has evolved into world leader in research and high-tech innovation. Technion, founded in 1912 by a group that included Albert Einstein, was created to train engineers to support the anticipated state of Israel. Its graduates helped to build the county’s infrastructure and started the high-tech industries that today make Israel a modern country with the greatest concentration of high-tech startup companies anywhere outside of Silicon Valley. More than 70 percent of the country’s founders and managers of high-tech industries are Technion graduates.
And like Cornell, Technion looks beyond borders. In its mission statement, it is “dedicated to the creation of knowledge and the development of human capital and leadership, for the advancement of the State of Israel and all humanity.”
With the creation of the Bruce Rappaport Faculty of Medicine in 1969, the Technion joined Cornell as one of a select group of institutions incorporating both engineering education and a medical school. Its campus is also on a hill, overlooking Haifa, where the view of the Mediterranean rivals Cornell’s vista of Cayuga Lake. In the city below such high-tech giants as Microsoft and Google have set up shop, hoping to take advantage of Technion research and recruit its students.
Shared research
Cornell and Technion faculty have been cross-pollinating for years, especially in engineering. Joseph Halpern, professor and chair of computer science, has been collaborating for more than 20 years with Yoram Moses, his first Ph.D. student and now a professor of computer science at Technion. In 1984, the two wrote a seminal paper about how two people — or two computer network nodes — could communicate and know for sure that their messages had been received. The paper earned them the Gödel Prize and the Dijkstra Prize, two of the most prestigious honors in computer science, and it has been cited more than 1,000 times. They have written a book on the topic and continue to issue joint papers.
Halpern can think of at least eight or nine other faculty members in his department alone who work with Technion researchers. It’s not because anyone told them to do this, he added. “People collaborate with others who share their interests,” he said. “[Technion] is strong in areas we’re interested in.” Personal visits back and forth are common, he noted, with travel often paid for by the US-Israel Binational Science Foundation (BSF), created in 1972 by the two governments to encourage collaboration between their researchers.
When you find those common interests, the collaborator may not even be in your own discipline. Frank Wise, professor of applied and engineering physics, has been working for years with Efrat Lifshitz, professor of chemistry at Technion, on nanocrystal materials that promise more efficient solar cells. “Her synthesis capability is more general and more informed than ours,” Wise explains. “She makes it, we calculate and measure.” They visit each other in alternate years, again with BSF funding.
Robert Kleinberg, assistant professor of computer science, has worked with Ron Lavi, senior lecturer in the Faculty of Industrial Engineering and Management at Technion, since 2003, when the two were in graduate school in California. They were at different schools, but became “conference buddies” because they shared an interest in the application of computer science to economics. Lavi visits Ithaca about once a year and Kleinberg travels to Haifa. In between they burn up bandwidth on Skype. The parallels between Cornell and Technion, Kleinberg said, “are personified in two people.”
An “ancillary benefit” of the collaboration, Kleinberg noted, was persuading Lavi’s star master’s student, Sigal Oren, to come to Cornell for her Ph.D. “She’s written some very provocative and newsworthy papers,” he said. “A good catch.”
Exchanging students and teachers
Other Technion grads have enrolled at Cornell, not surprising because they have already been selected for high academic standards. Andy Ruina, professor of mechanical and aerospace engineering, recalls a student who came with a recommendation almost biblical in tone: “To Yuvall Katzman metal is like clay, something to be formed into any shape you like.” After building some spectacular apparatus for Ruina, Katzman went on to a highly successful career as an inventor in Israel.
Technion has, understandably, special expertise in the management of water resources. Professors in Cornell’s School of Civil and Environmental Engineering (CEE) report ongoing collaborations with their counterparts at CEE-Technion. Hillel Rubin, professor emeritus of environmental, water and agriculture engineering at Technion and a specialist in the remediation of contaminated groundwater, was Mary Upson Visiting Professor at Cornell in 2003-04, working with Christine Shoemaker, the Joseph P. Ripley Professor of Engineering, to publish three papers on groundwater contamination.
Cornell faculty are just as likely to teach in Israel. Zygmunt Haas, professor of electrical and computer engineering, has just settled in for two semesters in the electrical engineering department at the Technion, at the invitation of the department chair, teaching a course in his specialty, wireless networks. An administrator at Technion can quickly reel off the names of 15 Technion faculty members, past and present, who have studied or taught at Cornell.
Cornell President David Skorton also has had Technion connections. He and Technion President Peretz Lavie developed a good relationship when Skorton led an American Jewish Committee Project Interchange tour of Israel with other university presidents in the summer of 2010. “Peretz and I hit if off, and then we reconnected over the NYC Tech Campus proposal,” Skorton said. In addition, he said, “Some years ago, when I was at the University of Iowa, I had the chance to visit the Technion and to establish a relationship with a late member of the Technion faculty, Sam Sideman [who led the Technion’s biomedical engineering department], and with Dr. Rafi Beyar, currently CEO and director general of the Rambam Health Care Campus in Haifa.”
MacArthur “genius award” winner Michal Lipson, associate professor of electrical and computer engineering and one of four current Cornell faculty members who are Technion graduates, finds yet another similarity between the two institutions: Both are somewhat isolated geographically. This helps explain their creativity, she suggested. “You don’t feel like you need to do what everybody else is doing.”
For Lipson, partnership in the New York City venture makes perfect sense. “I’m delighted to hear this news, as Technion is a second home to me,” she said. “Technion and Cornell are two world-class institutions, which house the world’s best scientists. This partnership stands for a very strong collaboration.”

Nanocrystals Polarised

Nanocrystals cheaper to catch Solar Power

Technion researchers polarize a nanometric-sized crystal by changing the composition of surrounding molecules. In the future, this could improve efficiency of 3G solar photovoltaic cells.

Technion researchers from the Sara and Moshe Zisapel Nano-Electronics Center successfully polarized a nanocrystal by changing the composition of the molecules surrounding it. This finding was just published in the prestigious scientific journal, Nature Materials.
Doctoral student, Nir Yaacobi-Gross, under the supervision of the head of the Zisapel Center, Prof. Nir Tessler, exchanged some of the molecules attached to the surface of the nanometric-sized crystal with different molecules whose chemical or atomic group anchoring them to the crystal’s surface was different. The researchers discovered that the lack of uniformity in the molecular covering caused the crystal to partially polarize. The research group led by Prof. Asher Schmidt of the Schulich Faculty of Chemistry also contributed to understanding the molecule-crystal connection process. 
As the paper shows, this discovery will likely have far-reaching consequences in as far as significantly improving the efficiency of solar cells. These are 3G photovoltaic cells that are being intensively developed around the world due to their relatively low cost (and therefore, their suitability for mass production). The solar cells used today are mostly silicon based and are expensive both in terms of production costs and in the energy required to manufacture them. The discovery by the Technion researchers changes the ability of nanocrystals to receive or give electrons to material surrounding it, which essentially means that they have changed the crystal’s characteristics.

 “Nano crystals of different materials are used to develop new light sources and solar cells.”

 “Nano crystals of different materials are used to develop new light sources and solar cells,” explains Prof. Tessler. “The nanocrystal is produced in a solution, is about 2-8 nanometers in diameter and covered by an organic molecule that stabilizes it and allows the nanocrystal to be dissolved in the proper fluids. In this case the solution is actually an ink containing opto-electronic materials and hence today there is a lot of activity going on around the world designed to integrate these materials in the field of printed electronics that will produce sheets of lights or sheets of solar cells.”
The researchers emphasize that in order to enable the integration of these new materials in opto-electronic devices, it is important to achieve control over their characteristics so as to be able to relate to them as building blocks to be used in engineering an advanced device.
In the early stages of the research in the Zisapel Center, it was found that organic molecules could be used to move the relative location of the particle’s level of energy. What surprised the researchers at this stage was the fact that the most important factor in this move was the atom found at the end of the molecule, which connects to the nanocrystal. The researchers showed that not only can the energy levels of the nanocrystal be moved relative to materials or to other nanocrystals, but that it was possible to change areas of this tiny crystal (approximately 4 nanometers in size) relative to other areas. “This study showed that we had a crystal that is inorganic but surrounded by organic molecules such that it constitutes an entity that is a hybrid of organic and inorganic material,” stresses Prof. Tessler. This distinction requires a change in the theoretical approaches that analyze these crystals and ignore their organic part (the organic molecules attached to them), mostly because “it just contributes to creating a solution.”

 “Nano crystals of different materials are used to develop new light sources and solar cells,” explains Prof. Tessler. “The nanocrystal is produced in a solution, is about 2-8 nanometers in diameter and covered by an organic molecule that stabilizes it and allows the nanocrystal to be dissolved in the proper fluids. In this case the solution is actually an ink containing opto-electronic materials and hence today there is a lot of activity going on around the world designed to integrate these materials in the field of printed electronics that will produce sheets of lights or sheets of solar cells.”
The researchers emphasize that in order to enable the integration of these new materials in opto-electronic devices, it is important to achieve control over their characteristics so as to be able to relate to them as building blocks to be used in engineering an advanced device.
In the early stages of the research in the Zisapel Center, it was found that organic molecules could be used to move the relative location of the particle’s level of energy. What surprised the researchers at this stage was the fact that the most important factor in this move was the atom found at the end of the molecule, which connects to the nanocrystal. The researchers showed that not only can the energy levels of the nanocrystal be moved relative to materials or to other nanocrystals, but that it was possible to change areas of this tiny crystal (approximately 4 nanometers in size) relative to other areas. “This study showed that we had a crystal that is inorganic but surrounded by organic molecules such that it constitutes an entity that is a hybrid of organic and inorganic material,” stresses Prof. Tessler. This distinction requires a change in the theoretical approaches that analyze these crystals and ignore their organic part (the organic molecules attached to them), mostly because “it just contributes to creating a solution.”

Israel Science Reaches for the Sun



GTEP ~ the Energy Core

Prof. Gideon Grader, director of the Grand Technion Energy Program (GTEP), was chosen to lead the Center of Excellence in Alternative Energies, as announced by the Council of Higher Education at the end of June 2011. This initiative, the fourth center to be named in the I-CORE (Israeli Centers of Research Excellence) framework, will incorporates 36 researchers at Technion, Weizmann Institute of Science, and Ben-Gurion University of the Negev (BGU).

GTEP together with Weizmann and BGU, combined efforts in a proposal for advanced research into solar fuels. This includes biomass generation; hydrogen production by water splitting; photo conversion of CO2 to CO; biomass conversion to ethanol and biodiesel; biomass gasification and catalytic fuel generation from H2, CO, CO2 and methanol.

The center, chosen by an international committee, is slated to enlist at least nine new researchers in the coming three years. Three new members, returning to Israel from Harvard and University of Michigan, will be recruited to Technion’s Faculty of Biology and Schulich Faculty of Chemistry this year.

New ways to Charge Solar Cells

Technion Researchers Find New Way to Charge Solar Cell Materials

Newswise — Solar power must become more efficient and less expensive to compete with energy produced by fossil fuels. Silicon-based solar cells are the dominant technology in the field, but the widespread adoption of these cells has been slowed by their high costs. Solar cells that use inorganic nanocrystals or “quantum dots” could be a cheaper alternative, but they are generally less efficient at turning solar energy into electricity.
Technion-Israel Institute of Technology researchers have now found a new way to generate an electrical field inside the quantum dots, making them more suitable for building an energy-efficient nanocrystal solar cell.
In their report in the October 9 issue of Nature Materials, Professor Nir Tessler (of the Zisapel Nano-Electronics Center in the Technion Department of Electrical Engineering) and colleagues describe how they “tuned” the electrical properties of quantum dots before testing their capabilities in a model solar cell.
Nanocrystal or quantum dots “are promising materials for low-cost and high efficiency solar cells” due to their unusual electronic properties, Tessler said. For instance, the size of a quantum dot is uniquely correlated to its light absorption, so changing a dot’s size can maximize its ability to harvest light within a solar cell.
To live up to their promise, however, the dots must share electrons efficiently-a feat that has been difficult to control. The Technion study offers a new way to bring an electrical charge to the dots-each about one-millionth the size of the period at the end of this sentence.
Tessler and colleagues were able to generate strong electrical fields within the dots by capping them with two different organic molecules. The chemical groups that attach the molecules to the dots’ surface generate the electrical field, they show.
Tessler said the findings give researchers one more method of controlling the building blocks of nanoelectronics. The dots are produced in an optoelectronic “ink” solution, he noted, which could make them suitable for future applications in “the field of printed electronics that will produce sheets of light or sheets of solar cells.”
The researchers hope to combine these findings along with their previous experiments that mix different kinds of nanocrystals, to discover whether combining the two methods might lead to even more efficient energy production.
The Technion-Israel Institute of Technology is consistently ranked among the world’s leading science and technology universities. Home to three of Israel’s five winners of the Nobel Prize in science, the Technion commands a worldwide reputation for its pioneering work in computer science, nanotechnology, biotechnology, energy, water-resource management, medicine, drug development, and aerospace. Headquartered in New York City, the American Technion Society (ATS) promotes scientific and technological research and education at the Technion.
