Microstructure, Phase Composition, and Mechanical Properties of Intermetallic Ni-Al-Cr Material Produced by Dual-Wire Electron-Beam Additive Manufacturing

open access: yesMetals
Electron-beam additive manufacturing is one of the most promising methods for creating complex metal parts and structures. Additive manufacturing has already gained wide acceptance in the creation of various constructions from aluminum, copper, titanium,

Beyond Fundamental Building Blocks: Plasticity in Structurally Complex Crystals [PDF]

open access: yesarXiv
Intermetallics, which encompass a wide range of compounds, often exhibit similar or closely related crystal structures, resulting in various intermetallic systems with structurally derivative phases. This study examines the hypothesis that deformation behavior can be transferred from fundamental building blocks to structurally related phases using the ...

Endohedral Coordination of Bulky Substrates in Metalloenzyme‐like Organometallic Nanotubes

open access: yesChemistry – A European Journal, Accepted Article.
Artificial receptors inspired by metalloenzymes share three key properties: a structurally flexible cavity, substrate binding via metal–ligand coordination, and metal‐based redox activity. Herein, we report an organometallic nanotube with such features based on our supramolecular pillarplex platform, with eight CuI centers integrated in its cavitand ...

Li16Sr6Ge6N, Li16Sr6Ge6.5 and related lithium alkaline‐earth metal tetrelides: Alternative filling of voids by nitride or tetrelide ions

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 648, Issue 23, December 13, 2022., 2022
Abstract Large black single crystals with a metallic luster of Li16Sr6Ge6N and several other representatives of the series Li16Ae6Tt6N and Li16Ae6Tt6.5 (Ae=Ca, Sr; Tt=Si, Ge, Sn, Pb) were grown from mixtures of the respective elements with addition of binary alkaline‐earth metal nitrides or lithium nitride in the case of the nitrides. For the synthesis

Molecular Rectangles Featuring Two Parallel NCN‐Coordinated Platinum Units: Enhancing Near‐Infrared Emission Through Excimer Formation

open access: yesChemistry – A European Journal, EarlyView.
Macro‐cycling into the near‐infrared: By incorporating two cyclometallated Pt(II) units into opposite sides of a molecular rectangle, the formation of near‐infrared‐emitting excited states that span the two units is promoted in solution, compared to the corresponding, acyclic, tweezer‐like complexes. A degree of molecular reorganization is nevertheless

Peculiarities of niobium-based superconducting alloys in the light of crystal chemistry: A brief survey [PDF]

open access: yesarXiv
In this survey, we focus on Nb-based binary intermetallic compounds, which have been widely used over the last 40 years to develop a range of superconducting applications, including non-standard engineering solutions in the design of large magnets.

Single Atom Sites in Ga‐Ni Supported Catalytically Active Liquid Metal Solutions (SCALMS) for Selective Ethylene Oligomerization

open access: yesChemPhysChem, EarlyView.
Supported catalytically active liquid metal solutions (SCALMS) based on liquid gallium‐nickel (Ga−Ni) alloys have demonstrated high catalytic activity and stability in the selective oligomerization of ethylene. In this study of novel Ga−Ni SCALMS, catalytic, spectroscopic, microscopic, and computational methods provide a unique and first insight into ...
