Red‐to‐Near‐Infrared Electroluminescence and Low‐Threshold Amplified Spontaneous Emission from Solution‐Processable Fluorescent Diketopyrrolopyrrole Derivatives

ChemPhotoChem, EarlyView.
The photophysical, electroluminescence, and amplified spontaneous emission properties of two solution‐processable fluorescent diketopyrrolopyrrole derivatives are examined in details. The results demonstrate that this type of organic near‐infrared light‐emitting materials are extremely promising for organic light‐emitting diodes and organic ...

Linear Discontinuity Sharpening for Highly Resolved and Robust Magnetohydrodynamics Simulations

International Journal for Numerical Methods in Fluids, EarlyView.
This study applies a reconstruction scheme, “hybrid MUSCL–THINC” for finite volume methods developed by Chiu et al., to magnetohydrodynamics (MHD) simulations. Furthermore, the robustness is improved by a modification that deactivates an artificial compression by THINC depending on the non‐linearity of MHD discontinuities.

The Astronomy Education Research Charter

Astronomy Education Review, 2009
The Astronomy Education Research Charter is a statement from members of the astronomy education research community. It was originally discussed at the 2007 Astronomy Education Research Symposium. A report of the symposium and a call for public participation in its creation was published in this journal (Price et al. 2008, Astronomy Education Review, 6,

Van der Waals heterojunctions with negative differential transconductance for broadband photodetection, multi‐valued logic, and artificial neuron

InfoMat, EarlyView.
This work explores a combination of two ultra‐thin materials, indium selenide (InSe) and black phosphorus (BP), to create a highly efficient electronic device. This device exhibits negative differential transconductance (NDT), which is useful for developing low‐power, high‐speed logic circuits and neuromorphic (brain‐inspired) computing.

Using Data Science in High School Astronomy [PDF]

arXiv
Astronomy datasets can be challenging to use for high school astronomy classes. Data science education pedagogy can be leveraged to create astronomy activities in which students interrogate data, create visuals, and use statistical thinking to construct astronomy knowledge.
