Disentangling types of lattice disorder impacting superconductivity in Sr2RuO4 by quantitative local probes

open access: yesAPL Materials, 2022
The unconventional superconductivity in Sr2RuO4 is infamously susceptible to suppression by small levels of disorder such that it has been most commonly studied in extremely high-purity bulk crystals.

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

open access: yesAdvanced 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.

Ruthenium-Based Sensors

open access: yesInorganics
In the periodic table of the elements, ruthenium occupies an excellent position, just below iron. And like iron, it possesses several oxidation states, with +2 and +3 being the most common.

Ruthenium-Mediated Regio- and Stereoselective Alkenylation of Pyridine

open access: yes, 2016
A novel alkenylation reaction of pyridine is developed. Heating a cationic ruthenium vinylidene complex [CpRu(CCHR)(PPh3)2]PF6 in pyridine at 100−125 °C for 24 h affords (E)-2-alkenylpyridine.

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

open access: yesAdvanced 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

Ruthenium-Catalyzed C–H Alkynylation of Aromatic Amides with Hypervalent Iodine–Alkyne Reagents

open access: yes, 2016
An efficient C–H activation method for the ortho alkynylation of aromatic N-methoxyamides with hypervalent iodine–alkyne reagent using a ruthenium catalyst is described. The reaction proceeds under mild reaction conditions with broad substrate scope.

Ruthenium-Catalyzed Transformation of Ethylene Glycol for Selective Hydrogen Gas Production in Water

open access: yes, 2023
We developed an efficient process for producing hydrogen gas from aqueous ethylene glycol (EG) at 90–160 °C over a ruthenium catalyst. We achieved a high yield of hydrogen gas (up to 3.0 n(H2)/n(EG)) and formic acid (85% yield) from ethylene glycol in ...

Non‐Additive Criteria Assessment in Sustainability Evaluation of High Entropy Alloys: A Toxicity‐Weighted Framework

open access: yesAdvanced Engineering Materials, EarlyView.
Sustainability assessment requires methodologies that appropriately distinguish between additive and non‐additive material properties. A toxicity‐weighted scoring system is developed and applied that accounts for the disproportionate influence of highly toxic constituents through nonlinear weighting functions, providing more realistic estimates than ...

Biological activity produced by ruthenium chloride on perfusion pressure, left ventricular pressure and heart failure using an isolated rat heart model [PDF]

open access: yesJournal of Krishna Institute of Medical Sciences University
Background: Several drugs have been used to treat heart failure, including digoxin, spironolactone, captopril, and valsartan; however, some of these drugs can produce different secondary effects.
