Luminescent coordination nanoparticles

Water-soluble lanthanide-containing coordination nanoparticles with a size around 4-5 nm were prepared by the growth confinement of the Tb-2(bdc)(3)(H2O)(4) three-dimensional network using an organic polymer; the terbium- and the europium-based objects pre ...

Development of Ruthenium Antitumor Drugs that Overcome Multidrug Resistance Mechanisms

Paul Joseph Dyson, Wee Han Ang, Andrew Douglas Phillips, Claudine Scolaro, Gianni Sava

Organometallic ruthenium(II) complexes of the general formula [Ru(η6-p-cymene)Cl2(L)] and [Ru(η6-p-cymene)Cl(L)2][BPh4] with modified phenoxazine- and anthracene-based multidrug resistanc ...

Investigation of atomic-layer-deposited ruthenium nanocrystal growth on SiO2 and Al2O3 films

Wei Chen, Min Zhang

The growth of ruthenium (Ru) nanocrystals on the SiO2 and Al2O3 films has been investigated using atomic layer deposition (ALD) method, indicating that much higher density Ru nanocrystals are grown on the Al2O3 film compared with the SiO2 film. Ru nanocrys ...
