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.

Implementing the Astronomy Education Research [PDF]

Highlights of Astronomy, 2005
I think there is nothing like the study of astronomy to capture the imaginations of our students, to make them understand phenomena, and to introduce them to the fundamental ideas and methods of science and mathematics. In my presentation, I will examine my research on effective teaching and learning of astronomy at the elementary school level, and how

Flux‐Regulated Crystallization of Perovskites Using Machine Learning‐Predicted Solvent Evaporation Rates for X‐Ray Detectors

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 ...

Rare‐Earth Ion Intercalation in Graphene via Thermal and Electrostatic Control

Advanced Materials, EarlyView.
Europium ions reversibly intercalate into the van der Waals gap of bilayer graphene when heat and electrostatic gate act together, switching the stacking order and electronic response on demand. Real‐time transport, simulations, and device tests expose a hidden 2D Eu sheet and its temperature‐tuned diffusion, showing a versatile electrochemical route ...

Advances in Topological Thermoelectrics: Harnessing Quantum Materials for Energy Applications

Advanced Materials, EarlyView.
Topological materials offer a novel platform for thermoelectric energy conversion through unique band features, including band inversion, linear Dirac bands, surface states, and Berry curvature. These quantum characteristics enable enhanced longitudinal and transverse thermoelectric effects, establishing topological thermoelectrics as a promising ...

Pre-service astronomy education of teachers [PDF]

Highlights of Astronomy, 2005
There is little research on elementary/secondary teacher preparation. Few teachers are called upon to teach astronomy specifically, or their astronomy teaching is peripheral to their main interest (e.g., general science at lower levels or physics at higher levels).

Airbrushing: A Novel Method for Preparation of High‐Emissivity Black Coating for Infrared Measurements

Advanced Materials Interfaces, EarlyView.
This study showcases the airbrush method, a novel coating technique for the preparation of thin black paint coatings for infrared camera measurements. Using the method, coatings with an emissivity of 0.95, and as thin as 3 µm can be prepared. The method is affordable, non‐destructive, and can be prepared onto a wide range of substrates while ...

Geometrically Confined Strain Engineering of MoS2 via Quasi‐Van Der Waals Recrystallization of Gold Nanopillars

Advanced Science, EarlyView.
Geometrically confined quasi‐van der Waals (qvdW) recrystallization of patterned gold induces localized tensile strain in monolayer MoS2, enhancing its optoelectronic performance. The strain, induced during annealing after hBN encapsulation, leads to a 65‐fold increase in photoluminescence and a two‐order magnitude boost in mobility, offering a ...
