Cost-effective dye-sensitized solar cells based on rutile-phase three-dimensional TiO hierarchical nanostructures.

Specifically engineered three-dimensional (3D) and 1D morphologies are expected to play significant roles in the development of next-generation dye-sensitized solar cells. In this study, using a hydrothermal approach without a surfactant or template, we attempted to synthesize a 3D hierarchical rutile titanium dioxide (TiO ) architecture by varying the growth temperature and time. X-ray diffraction patterns of the synthesized TiO correlated well with rutile TiO .

Age-dependent neurological phenotypes in a mouse model of PRRT2-related diseases.

Paroxysmal kinesigenic dyskinesia is an episodic movement disorder caused by dominant mutations in the proline-rich transmembrane protein PRRT2, with onset in childhood and typically with improvement or resolution by middle age. Mutations in the same gene may also cause benign infantile seizures, which begin in the first year of life and typically remit by the age of 2 years. Many details of PRRT2 function at the synapse, and the effects of mutations on neuronal excitability in the pathophysiology of epilepsy and dyskinesia, have emerged through the work of several groups over the last decade.

A non-invasive protocol for the determination of lumbar spine mobility.

OBJECTIVE: This article presents a non-invasive protocol for the determination of lumbar spine mobility and compares intersegmental lumbar spinal mobility data from 45 subjects using both radiographic (invasive) and videographic (non-invasive) techniques. DESIGN: Non-linear mathematical models were developed to transfer skin marker coordinates into corresponding vertebral body positions. BACKGROUND: To relate skin surface motion with that of the underlying vertebrae and to enhance the reliability of using the non-invasive technique relied on a model of transformation.
