As novel quantum fluorescent materials, QDs have longer term photo-stability, narrower emission range, stronger intensity, and broader UV excitation spectra than that of normal fluorescent materials. Due to quantum dots' (QD) quantum scale effect, QDs of different sizes can emit fluorescence of different colors with the same excitation light, making them suitable bio-probes in multiplexed detection,...
A new conventional magnets tokamak HL-2M (Ip < 3 MA, Bt = 2.4 T, R = 1.78 m, a = 0.65 m) will be built in Sout hwestern Institute of Physics (SWIP). The Ohmic Heating (O H) power supply feeds the OH coil, which may provide about 220kA. In order to make full use of the flux swing of OH coi l, 4-quadrant converter will be adopted. Both positive and ne gative converters are 12-pulse thyristor bridge...
