In this work, we report synthesis and characterization of Bi2O3 nanoparticles loaded on mesoporous MCM-41 nanoparticles by a simple solid-state dispersion (SSD) method. Monoclinic bismuth oxide nanoparticles were prepared by polyacrylamide gel method and used as loading materials on the prepared mesoporous MCM-41 as a supporting material. Fourier transform infrared spectroscopy (FT-IR), X-ray p...

A major revolution for electron microscopy in the past decade is the introduction of aberration correction, which enables one to increase both the spatial resolution and the energy resolution to the optical limit. Aberration correction has contributed significantly to the imaging at low operating voltages. This is crucial for carbon-based nanomaterials which are sensitive to electron irradiatio...

Particle detection in very noisy and low contrast images is an active field of research in image processing. In this article, a method is proposed for the efficient detection and sizing of subsurface spherical particles, which is used for the processing of softly fused Au nanoparticles. Transmission Electron Microscopy is used for imaging the nanoparticles, and the proposed algorithm has been t...

Si/Si0.97C0.03 superlattices grown on Si~001! substrates by Sb surfactant assisted molecular beam epitaxy are characterized by in situ reflection high energy electron diffraction ~RHEED!, atomic force microscopy, transmission electron microscopy ~TEM!, and high resolution x-ray diffraction. The RHEED shows that, in the absence of Sb, the growth front roughens during Si0.97C0.03 growth and smoot...

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 nanoparticles (SCMNPs) with 3-aminopropyl triethoxysilane gave aminopropyl-modified magnetite nanoparticles (AmpSCMNPs). Then, Schiff base condensation  of AmpSCMNPs with acet...

The influence of the particle size on magnetic behaviors of nickeloxide nanoparticles (NiO NPs) was reported. NiO NPs with a uniform particlesize were synthesized via a facile sol-gel method, and various sizes of NiO NPs(11, to 49 nm) were achieved by calcination at various temperatures (400, to 700°C). X-ray diffraction (XRD) analysis revealed that increasing the calcinationtemperature increas...

Green biosynthesis of silver - functionalized multiwalled carbon nanotube (Ag/FMWCNT) nanohybride from silver nitrate solution using water extract of Satureja hortensis L as reducing agent and FMWCNT as anchoring agent at room condition was succesfully carried out. Water-soluble organics present in the plant materials were mainly responsible for the reduction of silver ions to nano-sized Ag par...

In this study, we present a new technique called correlative atomic force and transmission electron microscopy (correlative AFM/TEM) in which a targeted region of a sample can be observed under AFM and TEM. The ultimate goal of developing this new technique is to provide a technical platform to expand the fields of AFM application to complex biological systems such as cell extracts. Recent adva...

Importance of transmission electron microscopy (TEM) in the carbon nanomaterials research is discussed. Carbon, is perhaps, the only element which has an infinite number of allotropes. Some of them can appear very similar. For example, carbon nanofibers and multiwalled carbon nanotubes looks similar when observed with scanning electron microscopy. It is almost impossible to distinguish between ...
