Lessons from Preah Vihear: Thailand, Cambodia, and the Nature of Low-Intensity Border Conflicts

open access: yesJournal of Current Southeast Asian Affairs, 2011
In 1962, the International Court of Justice ruled that the Preah Vihear temple lies within Cambodian territory. The status of the 4.6 km² of land surrounding the temple, however, remained unclear.

Tunable‐Threshold UV Dosimetry With Programmable Luminescent Tags via Oxygen‐Mediated Room‐Temperature Phosphorescence

open access: yesAdvanced Materials Technologies, EarlyView.
A fully organic UV threshold dosimeter is developed by exploiting the oxygen‐sensitive room‐temperature phosphorescence of a purely organic emitter in a polymer matrix. Upon reaching a specific cumulative UV dose, photochemical oxygen depletion triggers a sharp, high‐contrast emission.

Quality of Different Scales in an Online Survey in Mexico and Colombia

open access: yesJournal of Politics in Latin America, 2015
The formulation of theories and hypotheses is done at the level of concepts. These concepts are often tested by operationalizing them using survey questions.

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress

open access: yesAdvanced Materials Technologies, EarlyView.
Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

White Light Emission and Energy Transfer in Mixed‐Metal Europium/Terbium/Thulium Formate Metal–Organic Frameworks: Effect of Lanthanum Dilution

open access: yesAdvanced Optical Materials, EarlyView.
A series of Eu3+, Tb3+, Tm3+ and La3+ formate‐based (mixed)metal‐organic frameworks were synthesized and investigated for energy transfer and white‐light emission. Efficient Tb3+→Eu3+ transfer enabled tuneable luminescence, while Tm3+ incorporation afforded near‐white emission.

MANGO‐“Fruitcage”: A Conditional Photocage Utilizing a Fluorescence Light‐Up Aptamer

open access: yesAdvanced Optical Materials, EarlyView.
Fruitcaging ‐ a proof of concept study of a conditional photocage (Thiazol‐Orange) activated upon binding to the fluorescence light up aptamer (Mango). The prolongation of the excited state lifetime explains the redirection of the reactive pathway toward photocleavage and provides a sensitive spectroscopic readout.

On–Off Switchable Micromotors for Use in Steerable Microvehicles

open access: yesAdvanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,
