30-nano class Gallium Arsenide (GaAs) nano-transistor: comparative advantages in its performanceEasy manufacturing process: less than half the cost of commercializationIt is possible to receive and enjoy various multimedia contents such as music, movies, and other data, at speeds of several tens of Mbps using high-speed internet widely available in households. Studies on the improvement of communication speeds have been continuously conducted over the recent years.Professor Yoon-Ha Jeong and research team have successfully succeeded in developing 35-nano GaAs nano-transistors (metamorphic HEMT..
Ultra-fast flash light revealing mystery of atoms, into the world of attoseconds (10-18 second) Beyond the femtosecond (10-15 second) barrierFerroelectric RAM (FeRAM) is a type of non-volatile computer memory, similar to dynamic random access memory (DRAM) which can be found in majority of our computers. FeRAM uses a ferroelectric layer to achieve non-volatility and offers a number of advantages from lower power usage to faster writing speeds.Ferroelectrics such as PbTiO3 have usually two stable oppositely-polarized states without external electric fields, and the negatively-polarized state ca..
The invention of the scanning tunnel microscope (STM) opened the door to nanoworld, enabling humankind to actually touch and feel the individual atoms at the surface of a material. It has inspired a series of inventions such as the atomic force microscope (AFM), the lateral force microscope (LFM), the magnetic force microscope (MFM), etc. Recently, the scanning probe microscope (SPM), which encompasses all these inventions, has evolved into the millipede technology which has a potential to make competing data storage technologies obsolete. A common denominator of these exciting developments is..
It is well known that plants can fix carbon dioxide (CO2) into sugar. In plant cells, the chloroplast is responsible for fixing carbon dioxide into sugar. Thus chloroplasts as the factory for sugar production play essential roles not only for plants themselves but also for most of living organisms on Earth. However, chloroplasts are not just carbon dioxide fixing factory but also responsible for producing a large number of chemical compounds that are essential for plant growth and development. Interestingly, chloroplasts in plant cells are thought to be originated from ancestral cyanobacterium..
