A retrospective cohort study was conducted to evaluate the long-term visual outcomes of patients treated with ruthenium plaque brachytherapy for posterior choroidal melanoma. The study included 219 patients treated between January 2013 and December 2015. The article describes a case of treatment failure in an unidentified patient who underwent four years of ruthenium treatment for posterior choroidal melanoma. The specific details of the patient's age, sex, route of administration, and dosage were not provided. [Extracted from the article]

The article reports on scientific findings related to chemistry and physics. Physicist John Delaney has collaborated with other physicists, chemists, and conservators to probe famous artwork using spectroscopy, noting insights he gained into the artworks. Condensed matter physicists have discovered that nearly all common, everyday materials likely have topological properties. Engineers from the University of Minnesota have discovered magnetic properties of ruthenium.

The article discusses nuclear waste storage research on the role that ruthenium plays in preventing naturally-occurring hazardous nuclear material in Earth's crust, including radioactive caesium-13, from escaping into the atmosphere, referencing an article coauthored by scientist Evan Groopman in the "Proceedings of the National Academy of Sciences."

The NEMO 3 experiment is devoted to the search for decay and measurement of decay. Half-lives of the decay have been measured with high accuracy for 7 kg of 100Mo, , and for 1 kg of 82Se, . After analysis of data corresponding to 693 days, no evidence for decay was found. The obtained half-life lower limits at 90% C.L. for decay are for 100Mo and for 82Se. The double beta decay of 100Mo to the excited and states of 100Ru is also being studied with NEMO 3. [Copyright &y& Elsevier]

The article reports that the growing demand for cellular phones and flat-screen televisions is depleting globals supplies of metals such as bismuth, ruthenium, and indium, and raising supply prices exponentially. Comments from Rüdiger Kühr of the United Nations University in Tokyo, Japan regarding a global e-waste initiative are presented.

The article presents a study on electrons, conducted by Alexander Föhlsich and colleagues at the University of Hamburg, Germany. The study was published in the vol. 436 of the journal "Nature." The study reports that electrons can hop between atoms in a mere 320 quintillionths of a second. The researchers used a core-hole clock to time electrons as they zipped from a sulphur atom to an adjacent ruthenium metal surface. The researchers fired X-rays at the sulphur, causing an electron near the atom's centre to become excited and jump, leaving behind an empty "core-hole" in its place. They found it in a nearby ruthenium atom, meaning that it had gone across in a bit less time than it took to fill the core-hole.

The article focuses on platinum group metals (PGMs) and their properties. According to the author, PGMs, which include iridium, osmium, palladium, platinum, rhodium, and ruthenium, are among the rarest mineral commodities in the Earth's crust. PGMs are primarily used as catalytic converters that clean harmful exhaust from vehicle engines. They are also used in the chemical industry as catalysts in the production of nitric acid and in the petroleum refining industry.

The article reports on the promising potentials of ruthenium-based complexes as less toxic alternatives for metal-based anticancer cisplatin and other analogues that are still heavily employed in chemotherapy.

The article offers information on two studies which proved how organometallic nanoarchitectures could be used as nonlinear optical (NLO) switches. In the first study, cubic NLO properties of a heterobimetallic iron-ruthenium alkynyl complex was reversibly switched in solution between three different NLO states. The other study showed how a derivative complex with a pendant ethynyl group can be photochemically grafted onto a hydrogenated silicon surface.

Focuses on antiferro-magnetically coupled media, a hard disk drive design by IBM which involves the sprinkling of ruthenium on magnetic disks to increase their storage capacity.
