North Korea: Fading Totalitarianism in the "Hermit Kingdom" [PDF]
North Korea is perceived by many as one of the most totalitarian societies of modern time. But in the wake of the economic collapse of the 1990s, North Korean totalitarianism has grappled with new conditions.

Transparent Perovskite Light‐Emitting Diodes with Conductive Oxide Top Electrodes
Advanced Materials, EarlyView.Transparent perovskite light‐emitting diodes (TrPeLEDs) enable simultaneous display and transparency, expanding application possibilities. Using a metal oxide buffer layer and pulsed laser deposition, TrPeLEDs with diverse compositions and architectures are demonstrated.

North Korea and the Politics of Visual Representation [PDF]
Within international discourses on security, North Korea is often associated with risk and danger, emanating paradoxically from what can be called its strengths-particularly military strength, as embodied by its missile and nuclear programs-and its ...

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics
Advanced Materials, EarlyView.Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

How South Korean Means Support North Korean Ends: Crossed Purposes in Inter-Korean Economic Cooperation [PDF]
North and South Korea share the same political and strategic aim of integration and eventual unification of Korea, although they remain divided in their understanding of what should be the specific nature of the unified Korea.

Counterion‐Controlled Photocatalytic Doping of Organic Semiconductors
Advanced Materials, EarlyView.Counterion size is shown to actively control photocatalytic doping in organic semiconductors. Small anions suppress aggregation of acridinium photocatalysts, enhance electron transfer, and dramatically increase doping efficiency. This simple strategy enables conductivities up to 2000 S cm−1 in benchmark polymers, revealing counterions as a powerful yet

Famine in North Korea Redux? [PDF]
In the 1990s, 600,000 to 1 million North Koreans, or about 3 to 5 percent of the precrisis population, perished in one of the worst famines of the 20th century.North Korea is once again poised on the brink of famine. Although the renewed provision of aid

Advanced Materials, EarlyView.This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

The Hermit Kingdom’s Quest for Nuclear Weapons
Politikon, 2004 North Korea’s disclosure in October 2002 of its nuclear program based on uranium enrichment and its withdrawal from the Non-Proliferation Treaty (NPT) in January 2003, have led to an acute international crisis.
