Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Evolutionary Timescale of the DAV G117-B15A: The Most Stable Optical Clock Known [PDF]
, 2000 We observe G117-B15A, the most precise optical clock known, to measure the rate of change of the main pulsation period of this blue-edge DAV white dwarf.

Digital Astronomy in Education
International Journal of Online and Biomedical Engineering (iJOE), 2007 What causes seasons? Why day and night durations are so different with seasons? Why the position of the full moon seems directed to the south in summer while it seems directed to the north in winter? It is the purpose of this computer simulation to provide an interactive application, programmed in Java language to explore the issues related to the ...

High‐Entropy Magnetism of Murunskite
Advanced Functional Materials, EarlyView.The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

Al1‐xScxN‐Based Ferroelectric Domain‐Wall Memristors
Advanced Functional Materials, EarlyView.(a) Conductive atomic force microscopy (CAFM) image of the initial state bidomain structure of the Al0.85Sc0.15N (a) showing an enhanced conductivity of the head‐to‐head domain boundary. (b) CAFM image of the same area after application of several −65 V, 1 s voltage pulses showing lower conductivity of the generated tail‐to‐tail domain walls.

Advanced Functional Materials, EarlyView.By integrating machine learning into flux‐regulated crystallization (FRC), accurate prediction of solvent evaporation rates in real time, improving crystallization control and reducing crystal growth variability by over threefold, is achieved. This enhances the reproducibility and quality of perovskite single crystals, leading to reproducible ...
