Organic–Inorganic Hybrid Indium Halide Perovskites with Near‐Unity Photoluminescence Quantum Yield

open access: yesAdvanced Materials Interfaces, EarlyView.
The intrinsic low photoluminescence quantum yield (PLQY) of organic–inorganic hybrid halide perovskites has limited their applications in optoelectronic devices. In this work, novel (PMA)₄InCl₇·0.5H₂O single crystals are developed and a PLQY of approximately 100% through optimized antimony ion (Sb3⁺) doping is achieved. The light‐emitting diodes (LEDs)

Confronting Catastrophic Risk: The International Obligation to Regulate Artificial Intelligence [PDF]

open access: yesMichigan Journal of International Law 2024
While artificial intelligence (AI) holds enormous promise, many experts in the field are warning that there is a non-trivial chance that the development of AI poses an existential threat to humanity. Existing regulatory initiative do not address this threat but merely instead focus on discrete AI-related risks such as consumer safety, cybersecurity ...

Locally internal stability of weakly elastic Bresse system [PDF]

open access: yesarXiv, 2012
In their paper "Stability to weak dissipative bresse system", Alabau et al. studied the exponential and polynomial stability of the Bresse system with one globally distributed dissipation law. Our goal is to extend their results, by taking into consideration the important case when the dissipation law is locally distributed and to improve the ...

How Strongly Should We Protect and Enforce International Law?, University of Chicago Law School Workshop, March 2006 [PDF]

open access: yes, 2006
Observers of international law are obsessed with trying to explain and predict why and when states comply with international law. Doing so, they have consistently overlooked a logically preceding, but no less important, question: To what extent should ...

Development of ZnO Buffer Layers for As‐Doped CdSeTe/CdTe Solar Cells with Efficiency Exceeding 20%

open access: yesAdvanced Materials Technologies, EarlyView.
Highly resistive ZnO has been used as the buffer layer in As‐doped CdSeTe/CdTe solar cells to achieve efficiencies higher than 20%. STEM images and EDX mapping show that the quality of the front interface is dependent on the ZnO deposition temperature. Unusually, chlorine is not observed at the front interface using EDX when the ZnO is deposited at 100

Challenges imposed by International Environmental Law to Classical International Law

open access: yesACDI: Anuario Colombiano de Derecho Internacional, 2010
The emergence of international environmental law has produced important challenges to the very foundations of public international law. Traditional concepts such as state sovereignty, subjects of international law, and the early perspectives of national ...

Power Law in Sparsified Deep Neural Networks [PDF]

open access: yesarXiv, 2018
The power law has been observed in the degree distributions of many biological neural networks. Sparse deep neural networks, which learn an economical representation from the data, resemble biological neural networks in many ways. In this paper, we study if these artificial networks also exhibit properties of the power law.
