A phase III randomized-controlled, single-blind trial to improve quality of life with stereotactic body radiotherapy for patients with painful bone metastases (ROBOMET)

BMC Cancer, 2019
Background Bone metastases represent an important source of morbidity in cancer patients, mostly due to severe pain. Radiotherapy is an established symptomatic treatment for painful bone metastases, however, when conventional techniques are used, the ...

Iridium Corroles

Journal of the American Chemical Society, 2008
This work reports the synthesis and full characterization of 5,10,15-tris-pentafluorophenylcorrolato-iridium(III) bis-trimethylamine 1 and its octabromo derivative 2. The corrole is planar in both cases (the mean deviation from the plane is as low as 0.0371 A for 1 and 0.0325 A for 2), the UV-vis spectra display a split Soret band with a shoulder ...

Activated chemical bonds in nanoporous and amorphous iridium oxides favor low overpotential for oxygen evolution reaction

Nature Communications, 2022
To date, the search for active, selective, and stable electrocatalysts for the oxygen evolution reaction (OER) has not ceased and a detailed atomic-level design of the OER catalyst remains an outstanding (if not, compelling) problem. Considerable studies

Sol‐Gel‐Syntheses and Structural as well as Electrical Characterizations of Anatase‐ and Rutile‐Type Solid Solutions in the System IrO2−TiO2

ChemistryOpen, 2023
This paper describes solid solutions in the quasibinary oxide system iridium‐titanium IrO2−TiO2 with rutile and anatase crystal structures. Based on X‐ray diffraction evaluations using Rietveld refinements, changes of lattice parameters were determined ...

Needs assessment of gossamer structures in communications platform end-of-life disposal [PDF]

, 2013
The use of a gossamer structure is considered in application to end-of-life disposal of communications platforms. A wide-ranging survey of end-of-life disposal techniques and strategies is presented for comparison against a gossamer structure prior to a ...

Supported Iridium‐based Oxygen Evolution Reaction Electrocatalysts ‐ Recent Developments

ChemCatChem, 2022
The commercialization of acidic proton exchange membrane water electrolyzers (PEMWE) is heavily hindered by the price and scarcity of oxygen evolution reaction (OER) catalyst, i. e. iridium and its oxides.

Coordination engineering of iridium nanocluster bifunctional electrocatalyst for highly efficient and pH-universal overall water splitting

Nature Communications, 2020
Water electrolysis offers a promising energy conversion and storage technology for mitigating the global energy and environmental crisis, but there still lack highly efficient and pH-universal electrocatalysts to boost the sluggish kinetics for both ...
