More Progresses forHIRFL-CSR


LanzhouHIRFL-CSR observed on October 7, 2007a beam storage intensity exceeding the design indicator, a top international record for both highest energy and beam intensity.


HIRFL-CSR is an extension of HIRFL, built with an investment worth RMB 293.5 million. It is scheduled to be completed in five years. It mainly works on radioactive beam physics, including drip lines, properties of nuclear matters under high temperature and high density, high ionized Z physics, and high quality heavy particle beams/radioactive beams. Chinese researchers have harvested a number of internationally advanced findings in the said four areas, which makes China an important part of heavy particle study in the world. Meanwhile, the construction of the project has spurred up the development of associated high technologies for accelerator, super vacuum, and electronic cooling. 


Started in December 1999, the project is consisted of a number of sub-systems, including injection beam line, major ring (CSRm), beam splitter, experimental ring, experimental detecting device, and transformation of original devices and facilities of HIRFL. Upon its completion, the HIRFL-CSR will become an advanced device comparable to other world class devices, such as GSI in Germany, GANIL in France, and RIKEN in Japan. The large science project will also provide advanced experimental facilities for China’s basic researches in the area of nuclear physics, hadron physics, atomic physics, and high energy and density physics, benefiting a range of applied areas, including heavy particle radioactive material, heavy particle based cancer treatment, and space radiation study.


More Progresses for HTSC Study


In collaboration with a study team headed by P.C. Dai of Oak Ridge National Laboratory, a research team, led by WEN Haihu of State Key Laboratory for Superconductivity, CAS Institute of Physics and Center for Condensed Matter, has made important progresses in understanding the high-temperature superconductor mechanism of PrLaCeCuO, and unveiled a linkage between spin fluctuation and high-temperature superconducting. The finding was published in a recent issue of the Proceedings of the National Academy of Sciences.


The team led by WEN Haihu has been working on the subject for some years, with a number of laudable results. For example, it has found that some high-temperature superconductors possess Fermi arc, which means they will leave a new energy gap on the surface of Fermi arc in a superconducting state. Its size reflects the scale of superconducting energy. This model has been reconfirmed by other technical means, and has become a hot spot for research. In the study, researchers selected a mixed superconductor of PrLaCeCuO. They obtained high quality superconducting data in the broad temperature area, and accurately worked out the evolution of condensed energy in the magnetic field. At the same time, its US collaborators have observed a resonance peak in a neutron scattering experiment, and found that it has a magnetic field suppression identical to the variation of condensed energy in the magnetic field. The condensed energy and resonance peak would simultaneously disappear, when the magnetic field was higher than the critical magnetic field. Instead, an antiferromagnetic ordering would appear. These findings have confirmed the fact that there is a close relationship between HTSC and magnetic intensity. In addition, researchers also found that the competition between superconducting and antiferromagnetic ordering would result in two different basic states. These findings will improve people’s understanding of HTSC.


China First Monoclonal Targeting Drug for Liver Cancer


Iodine[131I] Metuximab, China’s first proprietary monoclonal antibody targeting drug granted with a national class I new drug certificate two year ago, has been put into clinical application in both Shanghai and Guangzhou. 


In July and August 2007, Shanghai No. 10 People’s Hospital and Guangzhou PLA 458 Hospital has used the new therapy to treat advanced primary liver cancers. According to a briefing, the previous clinical trials have shown that the new therapy produces a fine therapeutic effect. In the clinical application, doctors directly inject the drug into the arteries that feed blood to liver cancers via a tube, which produces a strong kill to the cancerous cells. Doctors found that the therapy can easily lead to relieved symptoms, such as pains, fever, and abnormal body temperature. Doctors told reporters that population-based studies are needed in order to further confirm the therapeutic effects of the new therapy.


Conducting Hollow Spheres of Polyaniline


Researchers at the Center of Molecular Sciences, part of the Institute of Chemistry under the Chinese Academy of Sciences, have recently achieved new progresses in developing multifunctional conducting hollow spheres of polyaniline. The finding was published in the recent issue of journal Advanced Materials as a cover story.


Based on the template-free synthesis approach developed by the Institute, researchers rolled out conductive and superhydrophobic rambutan-like hollow spheres of polyaniline, through self-assembly, using perfluorooctane sulfonic acid as a dopant, soft template, and superhydrophobic agent at the same time. The results show that the approach used is not only simple, but also that the hollow spheres have a large specific area and exhibit physical properties that are required for many applications in nanotechnology. It enhances the stability of conductivity of polyaniline, while protecting the biological materials inside from being contaminated, or damaged.  The novel hollow spheres are of broad application perspectives in numerous areas, including energy-loss free transmission, micro reactor, and controllable separation and release.


Relaxor Ferroelectric Study


Shanghai Institute of Applied Physics under the Chinese Academy of Sciences, in collaboration with National Synchrotron Radiation Lab, part of the University of Science and Technology of China, and CAS Shanghai Institute of Ceramics, has made important progresses in understanding the spatial structures of relaxor ferroelectric materials, using synchrotron radiation approach. Researchers found that the reorientation of PNR polarization is important for forming the macro polarization of relaxor ferroelectric body. The finding was published in a recent issue of Applied Physics Letters.


Researchers with Shanghai Institute of Applied Physics have for the first time observed the X ray scattering images reflecting the phase change of relaxor ferroelectric body, and obtained important parameters on PNR scale, using home made high temperature and pressure unit, and enhanced experimental devices. The experiment was made at NSRL in Hefei. Shanghai Institute of Applied Physics provided the PMN-PT monocrystalline materials. Experimental results show that in a zero electric field, PNR distributes in an oval shape, with a long and short axis respectively of 17nm and 10nm. The external electric field in the axial direction (100) is able to redirect the long axis of PNR. The reorientations mainly occur along the diagonal (1±1±1). PNR polarization and associated reorientation is important for forming the macro polarization of relaxor ferroelectric body.

Nanocarrier Cross Brain Barrier


Targeting nanocarrier drug and its application in treating cerebral diseases, a basic research project, has been established and entered the implementation phase. JIANG Xinguo, a research fellow at the Fudan University School of Pharmacy, said that the research will aim at four major brain diseases: brain tumors, cerebral infarction, dementia, and Parkinson's disease. Chinese scientists will develop novel, safe, and efficient targeting nanocarrier drugs to improve the effectiveness of cerebral disease treatment and accuracy of diagnosis, using modern nanotechnology, pharmaceutical techniques, and molecular biology.
