On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions
Advanced Materials, EarlyView.We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.

A Frequency-selective Filter for Short-Length Time Series [PDF]
An effective and easy-to-implement frequency filter is designed by convolving a Hamming window with the ideal rectangular filter response function. Three other filters, Hodrick-Prescott, Baxter-King, and Christiano-Fitzgerald, are critically reviewed ...

Development of Laterally Graded X‐Ray Multilayer Optics
Advanced Materials Technologies, EarlyView.This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

Resistive Heating for Inducing Localized Crystal Growth in Organic Thin Film Devices
Advanced Materials Technologies, EarlyView.Rubrene thin films are promising for organic optoelectronics due to high hole mobility. However, uncontrolled crystallization and grain boundaries from standard thermal processing hinder lateral device scalability. This work presents femtosecond‐laser micromachining and patterned resistive heating to induce localized, deterministic crystallization ...
