Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Separation and Pre-Concentration of Cu(II) Ions by a Synthesized Ion-Imprinted Polymer

Adsorption Science & Technology, 2012
A new ion-imprinted polymer (IIP) was prepared by the copolymerization of vinylpyridine as the monomer, ethylene glycol dimethacrylate as the cross-linker and benzoyl peroxide as the initiator in the presence of a Cu(II)–salen complex.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Encapsulation of tricopper cluster in a synthetic cryptand enables facile redox processes from Cu(I)Cu(I)Cu(I) to Cu(II)Cu(II)Cu(II) states

, 2020
One-pot reaction of tris(2-aminoethyl)amine (TREN), [Cu(I)(MeCN)(4)]PF(6), and paraformaldehyde affords a mixed-valent [TREN(4)Cu(II)Cu(I)Cu(I)(μ(3)-OH)](PF(6))(3) complex. The macrocyclic azacryptand TREN(4) contains four TREN motifs, three of which provide a bowl-shape binding pocket for the [Cu(3)(μ(3)-OH)](3+) core.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Hyperfine structure and isotope shift of neutral and singly ionized copper using Fourier transform spectroscopy

Results in Physics
The hyperfine structure (HFS) constants and isotope shifts (ISs) for some Cu I and Cu II levels were determined by fitting Fourier transform (FT) spectra from the US National Solar Observatory.

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Cu(II) Ion-Selective Electrodes Based on Cu(II) Complex with Cyclized Salophen

Zeitschrift für Naturforschung B, 2003
Several versions of Cu(II) ion selective electrodes (ISE), based on cyclized N,N'-bis(salicylidene)-o-phenylenediamine (salophen) complexes with Cu(II), were fabricated for determination of Cu(II) in aqueous solutions. The response of the ISE was optimized by variation of membrane composition and evaluation of various experimental conditions.
