NHC‐Copper(I)‐Mediated Functionalization of White Phosphorus

open access: yesAngewandte Chemie, EarlyView.
White phosphorus is functionalized by N‐heterocyclic carbene supported copper(I) complexes through redox‐neutral steps. Treatment of the resulting complexes with electrophiles releases the ligands from the metal center as asymmetrically substituted organophosphorus butterfly compounds.

Enhancement of strength mechanical and corrosion resistance of 7055 alloy with minor Sc and Y addition

open access: yesMaterials Research Express, 2021
A new type of 7055-Y-Sc alloy with high strength and corrosion resistance was prepared. Eutectic Al _3 Y particles with sizes in the range of 500–600 nm were found in the as-cast structure of the 7055-Y-Sc alloys.

Kinetics Study of Yttrium Leaching from Zircon Tailings Using Sulfuric Acid

open access: yesIndonesian Journal of Chemistry, 2023
From the analysis of zircon tailings using X-Ray Fluorescence (XRF), Yttrium is a rare earth element (REE) with the highest concentration compared to other REEs. The purpose of this study is to determine the best kinetic model for describing how sulfuric

Engineering of Crystal and Domain Structures in Epitaxial Y:HfO2 Thin Films by YSZ Substrate Miscut

open access: yesAdvanced Science, EarlyView.
We investigate how YSZ substrate miscut influences crystal structure and domain formation in epitaxial Y‐doped HfO2 thin films. Using magnetron sputtering, high‐resolution X‐ray diffraction, atomic‐resolution scanning transmission electron microscopy, and first‐principles calculations, we systematically examine the characteristics of thickness‐ and ...

Effects of yttrium on the microstructure, texture, and magnetic properties of non-oriented 6.5 wt% Si steel sheets by a rolling process

open access: yesMaterials Research Express, 2021
Non-oriented 6.5 wt% Si steel thin sheets with three different yttrium (Y) contents (0, 0.012, and 0.03 wt%) were prepared by hot rolling, warm rolling, intermediate annealing, cold rolling and final annealing processes.

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

open access: yesAdvanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

High‐Pressure Synthesis of Quantum‐Stabilised Manganese Superhydride MnH7

open access: yesAngewandte Chemie, EarlyView.
Superhydrides are a rarity in transition metal hosts. Through high‐pressure, high‐temperature diamond anvil cell studies, the most hydrogen‐rich transition metal hydride, MnH7${\rm MnH}_7$ has been synthesised. Density functional theory calculations demonstrate that zero‐point energy stabilises the crystalline structure that MnH7${\rm MnH}_7$ adopts ...

Sheet‐Size‐Dependent Mosaicity of 2D Phyllosilicate Membranes

open access: yesAdvanced Science, EarlyView.
This study explores how the size of 2D vermiculite sheets affects the structure of laminar membranes. High‐resolution x‐ray diffraction reveals how sheet size governs structural disorder and crystallinity. These changes directly impact ion permeability.
