Deciphering the interactions between single arm dislocation sources and coherent twin boundary in nickel bi-crystal
The introduction of a well-controlled population of coherent twin boundaries (CTBs) is an attractive route to improve the strength ductility product in face centered cubic (FCC) metals. However, the elementary mechanisms controlling the interaction between ...
NATURE RESEARCH2021Global maps of travel time to healthcare facilities
Access to healthcare is a requirement for human well-being that is constrained, in part, by the allocation of healthcare resources relative to the geographically dispersed human population(1-3). Quantifying access to care globally is challenging due to the ...
2020Proton-transfer-induced 3D/2D hybrid perovskites suppress ion migration and reduce luminance overshoot
Mohammad Khaja Nazeeruddin, Emad Oveisi, Hobeom Kim
Perovskite light-emitting diodes (PeLEDs) based on three-dimensional (3D) polycrystalline perovskites suffer from ion migration, which causes overshoot of luminance over time during operation and reduces its operational lifetime. Here, we demonstrate 3D/2D ...
2020The Long View Exploring Product Lifetime Extension
Less than nine months into 2017, more resources than our planet produces over the whole year were consumed globally, marked by Earth Overshoot Day. Short use and fast replacement of products increasingly dictates consumption patterns in many regions. As fa ...
