the mössbauer spectra of nanoferrite materials such as ni0.25mn0.75fe2o4, co0.5mn0.5fe2o4 and ni0.4co0.6fe2o4 have been reported and the above materials were prepared by sol-gel combustion method using metal nitrates as source material and polyvinyl alcohol(pva) as agglomeration reducing agent. as the structural, thermal and magnetic properties (vsm) of the above ferrites have been published al...

In this research zinc sulfide (ZnS) nanoparticles and nanocomposites powders were prepared by chemical precipitation method using zinc acetate and various sulfur sources. The ZnS nanoparticles were characterized by X-ray diffraction, scanning electron microscopy, ultraviolet-visible and fourier transform infra-red. The structure of nanoparticles was studied using X-ray diffraction pattern. The ...

ZnAlFe1−xSmxO4 (x = 0, 0.02, 0.04, 0.06, 0.08) spinel ferrites were successfully obtained for the first time via a sol–gel autocombustion technique using citric acid as combustion/chelating agent. These materials then employed photocatalysts degradation of Evans Blue, considered herein model organic pollutant. The XRD and FTIR analysis confirmed achievement pure ferrite structures all materials...

Despite the low cost, safety and high theoretical capacity of metallic zinc, zinc anodes face chronic problems, including dendrites, corrosion side reactions in aqueous zinc-ion batteries (ZIBs). Herein, a nitrogen-doped carbon nanoparticle coating layer derived from discarded cigarette filters is constructed to suppress parasitic dendrite growth. The dense isolates water anode, effectively inh...

Background: Bacterial resistance to the commonly used antibacterial agents is an increasing challenge in the medicine, and a major problem for the health care systems; the control of  their spread  is a constant challenge for the hospitals. Objectives: In this study, we have investigated the antimicrobial activity of the Zinc Oxide nanoparticles against clinical sample; Yersinia intermedia bact...
