LOL...yep, like my parents, "gotta watch my Chinese and Korean soap drama NOW! Why computer slow today?" Then calls me and ask me to stop what I'm doing and go look at their computer immediately.

Not long ago, “Scientific basis for the efficient rare earth resources use and associated green separation", a major project initiated under the National 973 Program, was officially launched at Peking University.

The project is designed to study the key issues involving rare earth resources development and purification, including the performance and share-activity relationship of novel extractants, molecular design model, the composition, structure and surface state of typical rare earth ores and their impact on selection and decomposition, clean sorting and decomposition techniques, micro rare earth extraction process, interfacial thermodynamic equilibrium and kinetic mass transfer equations, and the migration of trace impurities in rare earth purification process, among others.

One of the missions defined for the project is work out a novel rare-earth extractant that enjoys enhanced indicators, compared with the current P507 model.

With a budget of RMB 85 million, the project will work on seven topics: molecular design, synthesis, and performance of efficient rare earth extractants; interfacial molecule/ion interactions in an extraction process; design and simulation of new extraction equipment; complex countercurrent extraction theory and green rare earth separation process; and scientific basis of rare earth anhydrous halides and high purification process.

Scientists in China’s 28th Antarctic expedition team installed an Antarctic Watch Telescope at the Kunlun Station that is 4,000 meters above sea level. The telescope is designed to automatically watch the hundreds of millions of stars within the Milky Way via satellite communication and remote control. It is also enabled to search for extrasolar planets

According to a briefing, China plans to install three Antarctic Watch Telescopes at the Kunlun Station. The first Antarctic Watch Telescope installed is developed by the CAS Nanjing Institute of Astronomical Optics & Technology, with its operation control and data system being developed by CAS National Astronomical Observatories.

With a primary mirror 68 cm across, and an effective aperture at 50 cm, the telescope works on a large view field catadioptric optical system, able to perform pointing, tracking, focusing and other functions. It is the largest optical telescope in the Antarctic.

The first Antarctic Watch Telescope is also equipped with the largest single-chip CCD camera in the world, enjoying 100 million pixels. It can in a single exposure cover 4.3 square degrees of sky, equivalent to 18 moons in size, for effective astronomical surveys.

The telescope also possesses a powerful computer system for real-time processing and analysis of the huge amounts of data generated by the CCD camera. It can effectively spot transient objects, including supernovae and optical counterpart objects stemmed from gamma ray bursts

Up to date, China Antarctic Astronomy Center and other institutions have installed at the Kunlun Station a range of observing equipment and facilities, including astronomical site selection oriented automatic observatory, small optical telescope arrays, the Fourier transform spectrum analyzer among others.

The Antarctic Watch Telescope will make an uninterrupted watch even in the long polar nights that will soon come in the Antarctic, becoming a unique ground telescope for astronomical study.

Thanks to its 5-year painstaking efforts, Laboratory of Solar Thermal Power Generation, part of Chinese Academy of Sciences Institute of Electrical Engineering, has recently rolled out the world's first solar thermal power plant simulator.

The simulator is made up of a computer and simulation programs. The simulation programs present a STAR-90 simulation platform, an operator’s interface, and modeling components. The modeling components are able to work on sunlight collection, heat absorbing, energy storage, and conventional power generation.

A full-fledged power station can be modeled by connecting a range of sub-models for mass, energy and information flows. The simulation system is built on a physical experimental solar thermal power station in Badaling, capable of a range of modeling missions, including heliostat field, thermal heat sink, multi-phased thermal storage, auxiliary boiler, water supply system, and on-site electrical/thermal control, allowing a full multiple-task operation.

In addition, the system can be added with parabolic trough solar collector module, air heat sink module, and a variety of heat storage modules, to simulate a trough power plant, or a solar Brayton cycle system.

The development will facilitate the commercial application of solar thermal power generation in China, playing an important role in preparing solar power generation solutions, process optimization, design, and training.

Researchers at CAS Space Science and Applied Research Center collected three-dimensional wind field, temperature, and sodium atom density data ranging from 80km to 105km using a vehicle mounted wind/temperature lidar developed by the Center from December 28 to 30, 2010. This is the first sodium layer wind/temperature laser radar in the world.

Researchers have worked out solutions to a range of key technologies, including saturated sodium fluorescence spectroscopy, laser frequency stabilization, laser frequency modulation, pulse laser amplification, and vehicle mounting platform.

They received in the mid-October 2009 fluorescent signals from the top layer of middle sodium layer in the laboratory.

Researchers completed the installation and commissioning of the vehicle mounted system at a space environment field observation station under the Chinese Academy of Space Environment Space Center in Langfang in December 2010.

On December 28, 2010, the vehicle mounted lidar system emitted laser in three directions, and received fluorescent signals from three 1-m telescopes, which produced three-dimensional wind fields and temperatures.

Not long ago, an optical network test laboratory, jointly established by Beijing University of Posts and Telecommunications (BUPT) and JDSU, was officially inaugurated. JDSU shared with BUPT advanced high-speed optical communication test platforms and solutions.

Both sides are optimistic about the business perspective of high-speed transmission technology at the level of 100G or higher. BUPT is currently working on the transmission technology heading for the level of 100G or higher.

JI Yuefeng, Director of BUPT Institute of Photonics and Optical Communications said at the inauguration ceremony that one has to work hard to tackle the key technologies that will establish a high-speed transmission network at the level of 100G or higher.

The Institute has been granted with government support for developing advanced modulation, reception, and transmission technologies.

The efforts have not only resulted in technological innovations, but also brought out talented people who are good at such innovation. He expects more collaboration with JDSU in the area of ultra-high speed optical fiber communication, especially joint tests. JDSU provides the lab the measuring instruments needed for field network tests at different stages.
