      Dear Colleagues, Unsubscribe - Receiving email nano_indonesia@...
      This week you can learn about artificial leaves developed by researchers from North Carolina State University, the Air Force Research Laboratory and Chung-Ang University. The artificial leaves are composed of water-based gel infused with light-sensitive molecules - the researchers used plant chlorophyll in one of the experiments - coupled with electrodes coated by carbon materials, such as carbon nanotubes or graphite. The light-sensitive molecules get excited by the sun's rays and produce electricity, similar to plant molecules that get excited to synthesize sugars in order to grow. The findings prove the concept of making solar cells that more closely mimic how nature harnesses solar energy. The artificial leaves still have a relatively low efficiency so there is a long way to go before they can become a practical technology but the researchers believe that the concept of biologically inspired devices for generating electricity may in the future provide a real alternative to today’s solid-state technologies. The results have been published in the Journal of Materials Chemistry. Read this and the 7 other very interesting news below.

      Mimicking Nature, Water-Based 'Artificial Leaf' Produces Electricity
      A team led by a North Carolina State University researcher has shown that water-gel-based solar devices -- "artificial leaves" -- can act like solar cells to produce electricity.

      Measuring Atomic Memory with Nano Precision
      Researchers at IBM now know how long a single atom can "remember" its state.

      Nanotechnology Energy Generation using Sound
      Imagine cellular phones that can be charged during conversations and sound-insulating walls near highways that generate electricity from the sound of passing vehicles.

      Semiconductor could Turn Heat into Computing Power
      Computers might one day recycle part of their own waste heat, using a material being studied by researchers at Ohio State University. The material is a semiconductor called gallium manganese arsenide.

      New Ultracapacitor Recharges in under a Millisecond
      A new ultracapacitor or electric double-layer capacitor (DLC) design has been announced in the journal Science this week, and could pave the way for smaller and lighter portable electronics devices.

      Nanostructuring Technology creates Energy Efficient and Ultra-Small Displays
      University of Michigan scientists using AFOSR-funding have created the smallest pixels available that will enable LED, projected and wearable displays to be more energy efficient with more light manipulation possible and all on a display that may eventually be as small as a postage stamp.

      Growing Nanowires Horizontally Yields New Benefit: Nano-LEDs
      While refining their novel method for making nanoscale wires, chemists at the National Institute of Standards and Technology (NIST) discovered an unexpected bonus—a new way to create nanowires that produce light similar to that from light-emitting diodes (LEDs).

      The Horror of 80-hour Photomask Write Times
      If you think photomask write times are excessive now, just wait until the 20/22-nm node. At that point, the complexity of reticle enhancement techniques needed to make 193-nm wavelength lithography scanners write 22- or 20-nm features will require something like an 8X increase in write times from the 32-nm node for complex masks, according to Aki Fujimura, CEO of D2S Inc.
