1960 - Metal Oxide Semiconductor (MOS) Transistor Demonstrated
John Atalla and Dawon Kahng fabricate working transistors and demonstrate the first successful MOS field-effect amplifier.

In 1959 M. M. (John) Atalla and Dawon Kahng at Bell Labs achieved the first successful insulated-gate field-effect transistor (FET), which had been long anticipated by Lilienfeld, Heil, Shockley and others (1926 Milestone) by overcoming the "surface states" that blocked electric fields from penetrating into the semiconductor material. Investigating thermally grown silicon-dioxide layers, they found these states could be markedly reduced at the interface between the silicon and its oxide in a sandwich comprising layers of metal (M - gate), oxide (O - insulation), and silicon (S – semiconductor) - thus the name MOSFET, popularly known as MOS. As their device was slow and addressed no pressing needs of the telephone system, it was not pursued further. In a 1961 memo, however, Kahng pointed out its potential "ease of fabrication and the possibility of application in integrated circuits." But researchers at Fairchild and RCA did recognize these advantages. In 1960 Karl Zaininger and Charles Meuller fabricated an MOS transistor at RCA and C.T. Sah of Fairchild built an MOS-controlled tetrode. Fred Heiman and Steven Hofstein followed in 1962 with an experimental 16-transistor integrated device at RCA.

LG Display has announced its development of a newspaper-size flexible e-paper. The 19-inch wide (250x400mm) flexible e-paper is almost as big as a page of A3 sized newspaper. The product is optimized for an e-newspaper and able to convey the feeling of reading an actual newspaper. Additionally, as the product measures 0.3 millimeters thin, the e-paper weighs just 130 grams despite its 19-inch size.

LG Display arranged TFT on metal foil rather than glass substrate, allowing the e-paper display to recover its original shape after being bent. The use of a metal foil substrate makes the e-paper both flexible and durable while maintaining display qualities. In particular, LG Display applied GIP (gate-in-panel) technology which integrates the gate driver IC onto the panel. This improves its flexibility by removing driver ICs which are attached to the side of panel and hinder the bending of the display.

Colloidal particles are used as elemental building blocks to construct biofunctional nanostructures. In particular, multidimensional periodic arrangements of colloidal particles such as planar arrays and spherical assemblies can be used in a wide range of biological fields. The spatial regularity of such structures at the submicron-scale gives rise to special features such as a photonic bandgap (PBG) and selective permeability, which cannot be achieved by single colloidal particles. Recent advances in microfluidics technologies enable the fabrication of designed microparticles of equal size and shape in a continuous manner. Such microparticles have great potential for use in high-throughput screening and immunoassays. In this article, we review the current state-of-the-art in regard to colloidal assemblies and microparticles prepared by microfluidics for biological applications. This review consists of five main sections: (1) surface modification methods, (2) two dimensional (2D) and (3) three dimensional (3D) colloidal assemblies, (4) confined regular structures, and (5) novel fabrication strategies for advanced colloidal assemblies. In each section, we discuss not only the fabrication routes for biofunctional materials but also the characteristics of the materials and their biological applications. Finally, we outline the future perspectives for biofunctional colloidal materials.




Janus microspheres composed of superhydrophobic and hydrophilic hemispherical surfaces were prepared using photocurable Pickering emulsion droplets. Upon placement at an air-water interface, an impregnable superhydrophobic barrier with high flexibility is formed. These microspheres have great potential in size-dependent semipermeable membranes, floating micromachines, and superhydrophobic coatings.

G37 coupe Desire Beauty Intensity
The story of G37 narrates everything that men desire.  G37 is the reconciliation of everything I yearn for. He runs with me on the road that I take.  He is my alter ego that gazes back at me so that I can go faster, stronger, and more fiercely.




New FX

Fx doesn't protrude the yearning of expression nor the forceful beauty of G37.  He may not be near but is trustful and dignified.  He is my strong spirit that is yet to emerge. The overall goal was to extract the unique shapes of Infinity's auto models.

The KAI Robot Control (KRC) Module was developed at the Korean Advanced Institute of Science and Technology (KAIST) under the supervision of Professor Jong Hwan Kim. Professor Jong Hwan Kim is commonly know as the founder of Robot Soccer, he was a driving force in the creation of the Federation of International Robosoccer Association, commonly known as FIRA.

The KRC is based around an Atmel ATMega128 mcu - this is a fast RISC micro with 128 kBytes of FLASH for User Programs. The KRC can be programmed in one of two ways. Supplied with the KRC is a Flow-Chart based GUI programming environment. This is excellent for beginners as it teaches the fundamentals of developing flowcharts - this highlights the decision making processes and sequential operation of any program. For advanced users the KRC can be programmed in Assembly Language or C. More info on programming the KRC can be found in the Programming Info section.
