Although the hardware on imaging has a significant development in the past decades, the dynamic range of light we can reproduce is still quite limited compared to that of the real world. Particularly, people are often troubled when taking a photograph by that: a picture is under or over-exposed. T.....

It had been a very long dream in polymer science to synthesize long multi-block heteropolymer chains with an ordered sequence and controllable block lengths. Using ionic or living free radical polymerization, one can prepare copolymers with few blocks, such as diblock and triblock copolymers. The .....
