Four new heteroleptic iridium(III) complexes in the family Ir(dfppz)(2)((NN)-N-boolean AND), where Hdfppz = 1-(2,4-difluorophenyl)-1H-pyrazole and (NN)-N-boolean AND = 6-phenyl-2,2'-bipyridine (1), 4,4'-(di-tert-butyl)-6-phenyl-2,2'-bipyridine (2), 4, ...
Packing constraints and precise placement of functional groups are the reason that organic molecules in the crystalline state often display unusual physical or chemical properties not observed in solution. Here we report a single-crystal-to-single-crystal ...
In bulk composite materials, interfaces between adjacent materials can be neglected when evaluating the individual functional properties on the macroscopic scale. However, in nanostructured materials, what is described as an interfacial region can be a sig ...
New red sesquioxide phosphor, Eu(3+)doped (Y0.5La0.5)(2)O-3, was synthesized in the form of nanocrystalline powder with excellent structural ordering in cubic bixbyite-type, and with nanoparticle sizes ranging between 10 and 20 nm. Photoluminescence measur ...
We report on the results of directional point-contact Andreev-reflection (PCAR) measurements in Ba(Fe1-x Co (x) )(2)As-2 single crystals and epitaxial c-axis oriented films with x=0.08 as well as in Ca(Fe1-x Co (x) )(2)As-2 single crystals with x=0.06. The ...
Centimeter-sized single crystals of Ba2LaFeNb4O15 were grown from a high-temperature solution by using LiBO2 flux and a sealed platinum assembly. The obtained single crystals display the same physical properties as their ceramic counterparts. A frequency-d ...
Cerium(III) and cerium(IV) both form formate complexes. However, the species in aqueous solution and the solid-state structures are surprisingly different. Ce(III) shows only mononuclear complexes in aqueous solution, whereas Ce(IV) forms a stable hexanucl ...
An efficient method for modelling a polytypic family is presented with the example of cimetidine in the form C polymorph. The method exploits the (3 + 1)-dimensional superspace model, which is a powerful tool for the description, prediction and understandi ...
The new homoleptic ate U(III) siloxide [K(18c6)][U(OSi(O tBu)3)4] 2 was prepared in 69% yield by reduction of [U(OSi(OtBu)3)4] 3 with KC 8. The reaction of the neutral U(III) siloxide complex [U(OSi(O tBu)3)2(μ-OSi(OtBu) 3)]2 1 with adamantyl azide leads t ...
One of the most crucial steps in the development of oxide dispersion strengthened (ODS) reduced activation ferritic (RAF) steels is the engineering of their microstructure, which includes control of the type and size of oxide nanoparticles. In this work, ...
