Ocean color is hard to be observed as the solar radiation on the ocean surface is only about 30% of the total radiation after being attenuated by the atmosphere, and only visible light can be transmitted to the water. Besides, water column exhibits a depth-exponential decay signal at different rates at each wavelength. Therefore, imaging spectrometers, with broad spectrum and high spectral and spatial resolution, are required.
Recently, researchers from the Institute of Solid State Physics, Hefei Institutes of physical science, Chinese Academy of Sciences revealed the mechanism of the far/near-field and angular radiation distribution of the dipole-multipole (D-M) coupling system.
For every fusion facility around the world, it is striving for steady state fusion reaction with operation period as long as possible. However, it is not easy. Many challenges stand in the way. Reliable divertor scenario with high power handling capability is key among that.
Recently, researchers developed high-performance solar thermal copper sulfide photothermal ink and photothermal film. The team was led by Prof. WANG Zhenyang from the Institute of Solid State Physics, Hefei Institutes of physical science, Chinese Academy of Sciences.
ITER, one of the most ambitious energy projects in the world today, had its the first correction coil BCC/4 lowered into place on Oct.21.
