High photocatalytic yield in the non-oxidative coupling of methane using a Pd-TiO nanomembrane gas flow-through reactor.

The photocatalytic non-oxidative coupling of methane (NOCM) is a highly challenging and sustainable reaction to produce H and C hydrocarbons under ambient conditions using sunlight. However, there is a lack of knowledge, particularly on how to achieve high photocatalytic yield in continuous-flow reactors. To address this, we have developed a novel flow-through photocatalytic reactor for NOCM as an alternative to the conventionally used batch reactors.

The Role of Substrate Surface Geometry in the Photo-Electrochemical Behaviour of Supported TiO Nanotube Arrays: A Study Using Electrochemical Impedance Spectroscopy (EIS).

Highly ordered TiO nanotube (NT) arrays grown on Ti mesh and Ti foil were successfully prepared by a controlled anodic oxidation process and tested for water photo-electrolysis. Electrochemical impedance spectroscopy (EIS), combined with other electrochemical techniques (cyclic voltammetry and chronoamperometry) in tests performed in the dark and under illumination conditions, was used to correlate the photoactivity to the specific charge transfer resistances associated with a 3D (mesh) or 2D (foil) geometry of the support. The peculiar structure of the nanotubes in the mesh (with better light absorption and faster electron transport along the nanotubes) strongly impacts the catalytic performances under illumination.

Ultrasound Findings of Delayed-Onset Muscle Soreness.

The purpose of this series was to retrospectively characterize the ultrasound findings of delayed-onset muscle soreness (DOMS). The Institutional Review Board approved our study, and informed consent was waived. A retrospective search of radiology reports using the key phrase "delayed-onset muscle soreness" and key word "DOMS" from 2001 to 2015 and teaching files was completed to identify cases.

Tumors and Tumor-like Abnormalities of the Midfoot and Forefoot.

The differential diagnosis for a midfoot or forefoot mass or mass-like abnormality includes several common benign and malignant pathologies. Evaluation with imaging can often provide a diagnosis, or at least several likely etiologies, and guide management. Determining if a mass is cystic or solid with ultrasound or MRI can limit the differential diagnosis.

Dilemmas in distinguishing between tumor and the posttraumatic lesion with surgical or pathologic correlation.

This article discusses the most common diagnostic dilemmas when trying to distinguish between tumor and sports injury or other trauma. Bone tumors frequently occur in the same young active patients who experience sports injuries. If the pain persists longer than expected, imaging studies should be obtained to prevent a delay in diagnosis or an inappropriate arthroscopy.
