Characterization of defect density states in MoOx for c-Si solar cell applications

Layers of MoOx have been deposited by thermal evaporation followed by post-deposition annealing (PDA). The density of states (DOS) distributions of the MoOx films were extracted deconvoluting the absorption spectra, measured by a phothermal deflection spectroscopy setup, including the small polaron contribution. Results revealed a sub-band defect distribution centered 1.1 eV below the conduction band; the amplitude of this distribution was found to increase with PDA temperature and film thickness.

Resistive switching of anodic TiO2-based Memristors

2018

In recent years, memristors have attracted great attention owing to their simple fabrication process, high scalability, good compatibility with the CMOS technology, high switching speed, low power consumption and low cost for next-generation non-volatile memory technology [1]. The basic cell structure of a memristor is an insulator sandwiched between two metal electrodes. Among the materials being studied for memristors fabrication, binary metal oxides, such as TiO2, are most favourable because of their simple constituents, compatible with CMOS processes, and resistive to thermal/chemical damages. Anodizing is a an electrochemical low cost process carried out at room temperature to grow oxi…

Adherence issues related to sublingual immunotherapy as perceived by allergists.

Silvia Scurati1, Franco Frati1, Gianni Passalacqua2, Paola Puccinelli1, Cecile Hilaire1, Cristoforo Incorvaia3, Italian Study Group on SLIT Compliance 1Scientific and Medical Department, Stallergenes, Milan, Italy; 2Allergy and Respiratory Diseases, Department of Internal Medicine, Genoa; 3Allergy/Pulmonary Rehabilitation, ICP Hospital, Milan, ItalyObjectives: Sublingual immunotherapy (SLIT) is a viable alternative to subcutaneous immunotherapy to treat allergic rhinitis and asthma, and is widely used in clinical practice in many European countries. The clinical efficacy of SLIT has been established in a number of clinical trials and meta-analyses. However, because SLIT is self-administered…

Visual and Hearing Impairment Are Associated With Delirium in Hospitalized Patients: Results of a Multisite Prevalence Study

2021

Objective: Sensory deficits are important risk factors for delirium but have been investigated in single-center studies and single clinical settings. This multicenter study aims to evaluate the association between hearing and visual impairment or bi-sensory impairment (visual and hearing impairment) and delirium. Design: Cross-sectional study nested in the 2017 "Delirium Day" project. Setting and participants: Patients 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes, and hospices in Italy. Methods: Delirium was assessed with the 4AT (a short tool for delirium assessment) and sensory deficits with a clinical evaluation. …
