Transcripts For CSPAN2 U.S. Policy Toward North Korea 20170922

The significant interests we see in todays event of course is attributable to the quality and reputation of our speakers and our panelists. It is also a topic that is foremost on the minds of policymakers and embassies in washington, what kinds of realistic Diplomatic Options do we have to prevent a Nuclear Catastrophe with north korea, and how do we evaluate these options. Today as japanese citizens unfortunately grow accustomed to Missile Warning sirens and text messages, it is worth remembering that a decade ago this month the second phase actions of the sixparty talks were jointly decided for implementing north korean denuclearization in exchange for diplomatic normalization and Economic Cooperation. This included dismantlement or disablement of north Korean Nuclear facilities, among other steps. A year later, however, the sixparty talks had all been collapsed. This was the last major Diplomatic Initiative to address the socalled north korea problem. So today we are fortunate to he

Nonlinear Photochromic Properties in a Perylene-Substituted Rhodamine Spirolactam

Researchers develop a novel design approach to achieve nonlinear photochromism using easy-to-synthesize rhodamine spirolactam derivatives Nonlinear photochromic compounds that utilize low-energy light have received significant attention. They result in enhanced contrast and spatial resolution in photochromic reactions and allow multiple photofunctions in single molecules. However, they require complex molecular design, which limits their wide applicability. Now, researchers have achieved nonlinear photochromism using low-energy light in an easily synthesized perylene-substituted rhodamine spirolactam derivative, offering a novel design approach for simpler photofunctional materials.
