Dineodymium(III) ditungstate(VI), Nd2W2O9
Single crystals of monoclinic Nd2W2O9 were obtained by growth from tungsten borate flux in an atmosphere of air. The crystal structure consists of chains of distorted [WO6] octaÂhedra that run along the c axis of the structure, and of [NdO9] polyhedra that are connected via common faces and common edges to form a three-dimensional framework
The lanthanum(III) molybdate(VI) La4Mo7O27
Crystals of the orthoÂrhomÂbic phase La4Mo7O27 (lanthanum molybdenum oxide) were obtained from a non-stoichiometric melt in the pseudo-ternary system La2O3–MoO3–B2O3. In the crystal structure, distorted square-antiÂprismatic [LaO8] and monocapped square-antiÂprismatic [LaO9] polyhedra are connected via common edges and faces into chains along [010]. These chains are arranged in layers that alternate with layers of [MoO4] and [MoO5] polyhedra parallel to (001). In the molybdate layers, a distorted [MoO5] trigonal bipyramid is axially connected to two [MoO4] tetraÂhedra, forming a [Mo3O11] unit
Tract-based spatial statistics to assess the neuroprotective effect of early erythropoietin on white matter development in preterm infants
In a randomized double-blind placebo-controlled trial, O'Gorman et al. show that administration of erythropoietin within the first 42 hours after preterm birth improves white matter development in preterm infants. Improvements are seen in the corpus callosum, the anterior and posterior limbs of the internal capsule, and the corticospinal tract bilaterall
