Flattening Energy Puddles for Enhanced Charge Transport in Wrinkled WSe2

Small, EarlyView.
Strain‐inducing wrinkles in 1L‐WSe2 create carrier‐trapping energy puddles. Trioctylphosphine selenide (TOPSe) selectively passivates Se vacancies at these wrinkle sites, while steric hindrance suppresses basal‐plane reaction. Comprehensive suite of space‐resolved spectroscopic techniques reveals reduced nonradiative recombination, longer exciton ...

Transition of Ion Diffusion Mechanism in BaZr0.1Ce0.7Y0.1Yb0.1O3‐δ Electrolyte Under Real Operating Conditions

Small Methods, EarlyView.
Ion diffusion in the benchmark BZCYYb electrolyte is revealed to dynamically transition under realistic PCFC operating conditions. As temperature decreases, the electrolyte shifts from oxygen‐ion to proton‐dominant conduction via grain‐boundary hydrogenation and in situ hydration, even without external humidification.

Effects of yttrium on microstructure and mechanical properties of Mg-6Al magnesium alloy [PDF]

China Foundry, 2010
Since Y has a great solid solubility in magnesium alloys, it helps enhancing the heat-resistant property of magnesium alloys. The effects of Y on microstructures and mechanical properties of Mg-6Al alloy have been studied in this work.

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

Environmental Toxicology, EarlyView.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

Demonstration of a diamond anvil cell platform at the Linac Coherent Light Source: capabilities and outlook

Journal of Synchrotron Radiation, EarlyView.
A setup for fielding high‐pressure samples contained in diamond anvil cells (DACs) at the LCLS X‐ray free electron laser is described and example powder X‐ray diffraction data are presented. Future prospects for experimental capabilities in DACs enabled by the LCLS, such as short pulse laser interactions and multiple pulse modes, are discussed.A novel ...

Sharper, smaller, brighter: enhanced optical performance at the X06DA‐PXIII beamline after the SLS 2.0 upgrade

Journal of Synchrotron Radiation, EarlyView.
The X06DA‐PXIII beamline at the Swiss Light Source, operating since 2008 and contributing to over 2650 crystal structures, has been fully rebuilt to harness the reduced emittance and improved performance of the SLS 2.0 storage ring. Its new optical design, featuring a toroidal mirror close to the source, horizontal 1:2 focusing, and a Kirkpatrick–Baez ...
