Neodymium enriched TiO2 anatase-brookite powders were prepared by unconventional method via using pressurized hot fluids for TiO2 crystallization and purification. The photocatalysts were tested in the CH3OH photocatalytic decomposition and they were characterized with respect to the textural (nitrogen adsorption), structural (XRD, XPS, and Raman spectroscopies), chemical (XRF), and optical (DR...

Tracheal squamous cell carcinoma detected early in a high-risk patient has been treated twice with local neodymium-yttrium aluminium garnet laser therapy with good result so far. Ongoing bronchoscopic monitoring continues.

We present luminescent liquid-crystalline neodymium(III) complexes that contain three β-diketonate ligands and a mesogenic 1,10-phenanthroline ligand. Mesomorphism, including a nematic phase--very rare in lanthanide systems--is driven by the highly anisometric phenanthroline.

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...

The recent interest in the anticoagulant action of heparin has led us to seek a substance which might be similar in action but less expensive and simpler to administer. The anticoagulant effect of various rare earths given intravenously has been studied in lower animals (1, 2, 3). As far back as 1920, Esnault and Brou (4), and Grenet and Drouin (5) injected rare earths in 40 to 100 mgm. doses i...
