Reversible Coordination Modes in Piperazine‐Based Ru(II)‐p‐Cymene Acylthiourea Complexes: Modulating DNA Groove Binding for Selective Antimelanoma Activity

open access: yesChemMedChem, Volume 21, Issue 16, 27 August 2026.
Piperazine‐based monodentate and S,N‐bidentate Ru(II)‐p‐cymene complexes were synthesized through distinct coordination strategies and evaluated for antimelanoma activity. Among the investigated compounds, the S,N‐bidentate complex 2b exhibited significantly enhanced cytotoxicity (IC50 = 6.1 ± 0.8 ) against melanoma cells, particularly the A375 cell ...

Rapid solidification of immiscible alloys

Journal of Magnetism and Magnetic Materials, 2003
Abstract Immiscible alloys have been rapidly solidified for the preparation of granular materials with giant magnetoresistance properties. Au-based (Au–Co and Au–Fe) and Cu-based (Cu–Co and Cu–Fe) systems have been investigated. Single supersaturated solid solution has been obtained for Au–Fe, whereas three FCC solid solutions with different Co ...

Liquid immiscible alloys

Materials Science and Engineering Reports, 1995
Abstract The microstructure formation, during casting, of alloys being immiscible in the liquid state such as copperlead or aluminium-lead has gained renewed scientific and technical interest during the last fifteen years. Especially, a new experimental tool, research under reduced gravity conditions, was able to cast new, unexpected results and ...

Microgravity Solidification of Immiscible Alloys

open access: yesMRS Proceedings, 1998
AbstractThis paper covers findings obtained from the microgravity directional solidification of immiscible aluminum-indium alloys during the Life and Microgravity Spacelab Mission in 1996. Three alloys, one of monotectic composition and two alloys containing an excess of indium above the monotectic (i.e., hypermonotectic compositions) were solidified ...

Continuous Solidification of Immiscible Alloys and Microstructure Control

Microgravity Science and Technology, 2018
Immiscible alloys have aroused considerable interest in last few decades due to their excellent physical and mechanical characteristics as well as potential industrial applications. Up to date, plenty of researches have been carried out to investigate the solidification of immiscible alloys on the ground or in space and great progress has been made. It

Microstructure Evolution in Rapidly Solidified Immiscible Alloys

open access: yesMaterials Science Forum, 2006
We prepared Al-Bi alloys with our new aerogel counter gravity casting facility and Al-Pb alloys by simple mould casting with variable cooling rates. By counter gravity casting, it is possible to have directional solidification with flat isotherms and without forced melt flow during the casting process. Both methods allow studying the nucleation rate in

Structural morphologies of Cu–Sn–Bi immiscible alloys with varied compositions

open access: yesJournal of Alloys and Compounds, 2012
The macroscopic morphology of Cu-Sn-Bi immiscible alloys with compositions varying from hypomonotectic, monotectic to hypermonotectic alloys was experimentally investigated by conventional casting method.

Solidification in immiscible alloys

Advances in Space Research, 1993
Abstract Low-gravity processing of immiscible alloys is usually associated with an attempt to prevent sedimentation of the higher density liquid phase in order to form a dispersed microstructure. However, there are many factors in addition to gravity level which can influence the structures produced.

Mechanically driven alloying of immiscible elements

Physical Review Letters, 1992
We report on the formation by mechanical alloying of fcc solid solution of Fe and Cu, which are immiscible. Intense codeformation of Cu with Fe and other high-melting bcc metals generates small fragments with tip radii of the order 1 nm such that capillary pressures force the atoms on these fragments to dissolve.

A nanoglass alloying immiscible Fe and Cu at the nanoscale

Nanoscale, 2015
Synthesized from ultrafine particles with a bottom-up approach, nanoglasses are of particular importance in pursuing unique properties. From different kinds of nanoglasses with immiscible metals, nanoglass alloys are created, which may open an avenue to an entirely new world of solid solutions.
