H. E. Ali I Al-Naimi, Minister of Petroleum and Mineral Resources and Chairman of the KAUST Board of Trustees, announced on February 16 that the Board of Trustees has appointed Professor Jean-Lou Chameau as the next President of KAUST. Professor Chameau, President of the California Institute of Technology (CalTech), will become the second President of KAUST later this year.

You are in a shopping mall and your toddler suddenly wanders off. Searching frantically, you soon find him in a neighboring shop, but the minutes he was lost felt like hours. This type of ordeal inspired parent and faculty member Atif Shamim to explore a possible solution. The Integrated Microwaves Packaging Antennas & Circuits Technology (IMPACT) Lab at KAUST, part of the Computer, Electrical, and Mathematical Sciences and Engineering Division, has developed a prototype device that is low-cost, wearable, and capable of tracking minors and other people or objects with high accuracy both indoors and outdoors through the use of an internet-enabled phone or other computing gadget. Led by Dr. Atif Shamim, Assistant Professor of Electrical Engineering, the team, including students Rana Bilal and Fahad Farooqui and postdoctoral fellow Dr. Hammad Cheema, is using a new inkjet-printing technology to develop a paper-based, wearable tag. The choice of paper over traditional substrates seems unconventional, but it offers a new paradigm of inkjet-printed electronics. The paper is lightweight, flexible, biodegradable, and comes from a renewable source, and with TRACKING SUCCESS | Continued on p5

Exploring the Beauty of Patterns in Lipid Monolayers “Patterns are beautiful,” says Sahraoui Chaieb, Associate Professor of Mechanical Engineering and Materials Science and Engineering in the Division of Physical Science and Engineering. His research and experimental laboratory work at KAUST on lipid molecules forming patterns was published in the February 7 issue of the high-impact journal Soft Matter, and was also featured on the cover.

Professor Jean Fréchet, second from left, is presented with a gift from KAUST Leadership at a reception honoring his being awarded the Japan Prize.
Professor Fréchet Honored at Reception Professor Jean Fréchet, Vice President of Research, who was named co-recipient of the 2013 Japan Prize, was honored recently with a university reception to mark this outstanding accomplishment. The prize acknowledges original and outstanding achievements in science and technology which “advance the frontiers of knowledge and serve the cause of peace and prosperity for mankind.” KAUST President Choon Fong Shih said, “We have gathered to show how thrilled we are for Jean. We all recognize that he is multi-talented and continues to add tremendously to KAUST’s efforts in scientific advancement and technological innovation.” Prof. Shih said Prof. Fréchet’s accomplishments were lauded by several Nobel Laureates who sent their congratulations upon hearing of the prize. Prof. Shih, Provost Stefan Catsicas, and Executive Vice President of Administration and Finance Nadhmi Al-Nasr presented Prof. Fréchet with a limited edition reprint of the Kitab alDiryaq, a scientific work rich in calligraphy and illustration from the Golden Age of Islamic Civilization.

TRACKING SUCCESS | Continued from p1 the right tweaking, it can be made hydrophilic or hydrophobic, opaque or almost transparent, delicate or strong, coarse or smooth.
Prof. Atif Shamim shows off his small, paper-based, inkjet-printed, low-cost tracking tag.
“The other major factor favoring paper is its extremely low cost, as it is approximately ten times cheaper than a plastic film,” says Prof. Shamim. Another distinct advantage of this technology involves its transition from prototype to mass-scale production, where electronics can be printed roll-to-roll and reel-to-reel with speeds of up to 30 meters per second. “This means that eventually we will be able to print low-cost and flexible electronics like newspapers and magazines with very fast turnover times,” Prof. Shamim adds. Until recently, inkjet-printed electronics on paper were difficult to produce due to the poor conductivities of the nanoparticle inks. The latest developments in materials science have improved these conductivities and made the inks comparable to bulk metals. This has triggered an interest in printing electronics on unconventional substrates such as plastics, glass, leather, and paper, enabling countless possible applications of this technology. For example, the wearable tracking tag can be used not only for minors but also for tracking the elderly and family pets. In addition, the تابع استكشاف أمناط الدهون أحادية الطبقة
