Crystallisation of yttrium and other trivalent metal cations of similar radius with racemic N,N'-2-methylpiperazinebis(methylene phosphonic acid) gives a small pore bisphosphonate metal-organic framework solid displaying coordinative and hydrogen bonding and permanent porosity.

Two cases of acute rupture of the knee joint are reported after the intra-articular injection of radioactive yttrium 90. It is suggested that this may be a complication of intra-articular radioactive injections.

Control of spin waves in a ferrite thin film via interfacial spin scattering was demonstrated. The experiments used a 4.6  μm-thick yttrium iron garnet (YIG) film strip with a 20-nm thick Pt capping layer. A dc current pulse was applied to the Pt layer and produced a spin current across the Pt thickness. As the spin current scatters off the YIG surface, it can either amplify or attenuate spin-w...

There is an ever-expanding body of clinically oriented literature that demonstrates the efficacy of photorejuvenation as a means of enhancing the appearance of skin. From traditional fully ablative laser resurfacing to nonablative laser therapy to fractionated photothermolysis, there is substantial evidence of efficacy, including a number of randomized, controlled trials. There have also been s...

In ferromagnets, magnons may condense into a single quantum state. Analogous to superconductors, this quantum state may support transport without dissipation. Recent works suggest that longitudinal spin transport through a thin-film ferromagnet is an example of spin superfluidity. Although intriguing, this tantalizing picture ignores long-range dipole interactions; here, we demonstrate that suc...

A simple way to detect and remove trace amounts of WO4(2-) ions from an aqueous solution was demonstrated by their light-harvesting ability and selective excitation energy transfer to a Tb-doped layered yttrium hydroxynitrate matrix.

Selective internal radiation therapy (SIRT) using 90-yttrium is a local therapy for unresectable liver malignancies. Non-targeted 90-yttrium diversion via a patent hepatic falciform artery (HFA) is seen as risk for periprocedural complications. Therefore, this study aimed to evaluate the impact of a patent HFA on SIRT. 606 patients with SIRT between 2006 and 2012 were evaluated retrospectively....

The morphology and electronic structure of Pd clusters grown on oxidized yttrium surfaces are investigated by scanning tunneling microscopy and ultraviolet photoelectron spectroscopy. The hydrogen sorption mediated by the Pd clusters is determined from the optically monitored switching kinetics of the underlying yttrium film. A strong thickness dependence of the hydrogen uptake is found. The el...
