In this work, a new hybrid organometallic-inorganic hybrid nanomaterial was prepared by immobilization of acetyl ferrocene on the surface of magnetite nanoparticles.Covalent grafting of silica coated magnetite Hatchets nanoparticles (SCMNPs) with 3-aminopropyl triethoxysilane gave aminopropyl-modified magnetite nanoparticles (AmpSCMNPs).Then, Schif
Objective: This article aims to explore the role and responsibility of physicians in the era of social media; the authors take as an example of the current pandemic of Coronavirus disease 2019 (COVID-19).Also, we highlight how social media impact the way populations trust and follow the recommendations of the governments.Methods: We identified rele
Since the weak fault characteristics of mechanical equipment are often difficult to extract in strong background noise, stochastic resonance (SR) is widely used to extract the weak fault characteristics, which is able to utilize the noise to amplify weak fault characteristics.Although classical bistable stochastic resonance (CBSR) can enhance the w
Herein, we discuss the in situ measurement of the electron temperature in the ionosphere/plasmasphere by means of DC Langmuir probes.Major instruments which have been reported are a conventional DC Langmuir probe, whose probe voltage is swept; a pulsed probe, PROTEIN WATER TROPICAL LIMON which uses pulsed bias voltage; a rectification probe, which
Subject to investigate a work is the analysis of franchising as a specific form of international trade that follows a growing trend.This stems from the Vacuum Wheel very essence of franchising, which provides an opportunity for entrepreneurs with insufficient experience to start their own entrepreneurial venture, and over time gain satisfactory mar
