Electrochemical Behavior of Al/Mg Alloys Immobilized in a Magnesium Potassium Phosphate Cement-Based Mortar.

Portland cement is extensively used for the conditioning of radioactive waste. However, its high alkalinity is a serious obstacle to the stabilization of waste containing aluminum metal since aluminum is oxidized by the pore solution with the production of dihydrogen. This work investigates the potential of an alternative binder, magnesium potassium phosphate (MKP) cement, for the stabilization of Al-Mg alloys comprising 2 to 4.

Hybrid Fluoro-Based Polymers/Graphite Foil for H/Natural Gas Separation.

Membrane technologies and materials development appear crucial for the hydrogen/natural gas separation in the impending transition to the hydrogen economy. Transporting hydrogen through the existing natural gas network could result less expensive than a brand-new pipe system. Currently, many studies are focused on the development of novel structured materials for gas separation applications, including the combination of various kind of additives in polymeric matrix.

Self-reported smell and taste recovery in coronavirus disease 2019 patients: a one-year prospective study.

Purpose: The aim of the present study was to estimate the 1 year prevalence and recovery rate of self-reported chemosensory dysfunction in a series of subjects with previous mild-to-moderate symptomatic COVID-19.

Methods: Prospective study based on the SNOT-22, item "sense of smell or taste" and additional outcomes.

Results: 268/315 patients (85.

Surgical resection of oral cancer: en-bloc versus discontinuous approach.

Objectives: In the past literature agreed on treating oral carcinomas, using an "en-bloc" resection (EBR) but recently minimally invasive transoral surgery has spread as the preferable treatment for selected cases. This latter technique, which is performed with a discontinuous resection (DR), allows for a satisfactory postoperative quality of life (QoL) maintaining good survival rates.

Materials And Methods: In this study, we analyzed data about 147 surgically treated patients with oral cancer involving tongue and floor of the mouth.
