High-performance and cost-efficient electrocatalysts and electrodes are needed to improve the hydrogen evolution reaction (HER) for the hydrogen (H) generation in electrolysers, including microbial electrolysis cells (MECs). In this study, free-standing carbon nanofiber (CNF) films with supported cobalt phosphide nanoparticles have been prepared by means of an up-scalable electrospinning process followed by a thermal treatment under controlled conditions. The produced cobalt phosphide-supported CNF films show to be nanoporous (pore volume up to 0.

However, testing their effectiveness is essential for avoiding any environmental or adverse human health risk attributed to nanoparticle-based formulations, especially insecticides. Recently, organic nanoparticles of bifenthrin, a pyrethroid insecticide, were successfully synthesized by laser ablation of solids in liquid technique, with the most probable size of 5 nm.

This project was completed with the support of the Regional Health Agency (ARS) and aims to secure the medication circuit. The methodology for qualifying the computer system and production, the implementation of the medication circuit and the inter-site logistical organization are presented.

We assessed the immunogenicity of BNT162b2 (Pfizer/BioNTech) administered as a second dose in healthcare workers primed with ChAdOx1-S (Vaxzevria, AstraZeneca).
Methods: 197 healthcare workers were included in a monocentric observational study in Foch hospital, France, between June and July 2021.
Objectives: A strong COVID-19 vaccine campaign is needed to reach the herd immunity and reduce this pandemic infection.
Study Design: In the Foch Hospital, France, in February 2021, 451 healthcare workers were vaccinated by a first dose of AstraZeneca vaccine.
Methods: Adverse effects were reported to our pharmaco-vigilance circuit, by an online and anonymous questionnaire following the first weeks of the vaccinal campaign to healthcare workers.
