This paper reports the continuous reductive amination of different molecules, including biomass-related compounds, over carbon-supported FeNi nanoparticles obtained on the basis of inexpensive and abundant metal precursors and cellulose. A biorefinery case study for the preparation of pyrrolidones via acid-catalyzed hydrolysis of glucose followed by reductive amination of the obtained levulinic...

Some FeNi-Ag granular films of composition Fe ld%.w‘h8z.2z (sample A) and Fe7.62Ni16.4Ag75.98 (B) were prepared by using rf magnetron sputtering, gnd once deposited were rapidly annealed at 600, 650, and 750 “C. All samples displayed giant magnetoresistance. The zero-field-cooled and field-cooled processes evidence the segregation of ferromagnetic particles with a broad size distribution. The t...

Synthesis of noble-metal-free electrocatalysts for green hydrogen production is crucial to overcoming the energy demand modern society. One most competitive and alternative evolution reaction (HER) molybdenum disulfide (MoS2)-based composites. Herein, it shown that MoS2 nanosheets grow on FeNi@N-doped graphene nanoparticles/N-doped carbon matrix (FeNi@NG/NCM@MoS2), using hydrothermal method. Fe...

this paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. among common magnetic nanoparticles, magnetite (fe3o4) and maghemite (g-fe203) are popular candidates because of their biocompatibility. natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...

In this work the structure, magnetic properties and of magnetocaloric effect large batches FeNi nanoparticles were studied for selected compositions close to invar. Nanoparticles synthesized by method electric explosion wire using various technological parameters ensuring difference in their dispersion parameters. The main variable parameter was degree overheating material. use different condit...

in this work firstly fe2o3 nanoparticles were synthesized via a simple chemical method. properties of the product were examined by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and fourier transform infrared (ft-ir) spectroscopy. vibrating sample magnetometer (vsm) shows nanoparticles exhibit ferromagnetic behavior. to continue some of the 2-naphthol condensed 1,3-oxazinon...

FeNi/V nanomultilayered films with different V layer thicknesses were synthesized by magnetron sputtering. By adjusting the thickness of the V layer, different interfacial compressive stress were imposed on FeNi layers and the effect of interfacial stress on martensitic transformation of the FeNi film was investigated. Without insertion of V layers, the FeNi film exhibits a face-centered cubic ...

Multilayered [FeNi (100 nm)/Cu (3 nm)]5/Cu (500 nm)/[Cu nm)/[FeNi nm)]5 structures were used as sensitive elements of the magnetoimpedance (MI) sensor prototype for model experiments detection magnetic particles in blood vessel. Non-ferromagnetic cylindrical polymer rod with a small inclusion was sample mimicking thrombus The made epoxy resin an composite containing 30% weight fraction commerci...
