Among the techniques of electron microscopy, scanning electron microscopy (SEM) represents a high-performance method of investigating structures and devices in the domain of nanometer dimensions. This paper is a synthesis of the possible applications of SEM in the investigation of the nanometer domain, nanomaterials and nanotechnologies. It includes the results of the authors’ research work as ...

In the scanning electron microscope (SEM), specially designed microrobots can act as a flexible assembly facility for hybrid microsystems, as probing devices for in-situ tests on IC structures or just as a helpful teleoperated tool for the SEM operator when examining samples. Several flexible microrobots of this kind have been developed and tested. Driven by piezoactuators, these few cubic cent...

The availability of atomically resolved imaging modalities enables an unprecedented view into the local structural states of materials, which manifest themselves by deviations from the fundamental assumptions of periodicity and symmetry. Consequently, approaches that aim to extract these local structural states from atomic imaging data with minimal assumptions regarding the average crystallogra...

A scanning electron microscopy (SEM) and transmission electron microscopy (TEM) study was made of lesions from acute, experimentally induced cases of jaagsiekte. In the SEM study tumour cells were easily identified by the abundant microvilli on their peripheral surface. The SEM study gave further insight into the development of lesions and the spatial relationship of cells involved in jaagsiekt...

Despite being an excellent tool for investigating ultrastructure, scanning electron microscopy (SEM) is less frequently used than transmission electron microscopy for microbes such as viruses or bacteria. Here we describe rapid methods that allow SEM imaging of fully hydrated, unfixed microbes without using conventional sample preparation methods. We demonstrate improved ultrastructural preserv...

The nanomaterials have important application in different field of science such as biology and pharmacology, which draws the attention of biologists towards this field of study more than before. As the worldwide mortality rate is high due to the pathogens and especially because of the bacteria associated Aeromonas and the antibacterial effect of metal nanoparticles is well known for ce...

The aim of this work was to study the potential application edible films obtained by complex coacervation promoted electrostatic interactions between positively charged chitosan (CH) 3% (w/w) and negatively whey protein isolate (WPI) (w/w). Preliminary assays turbidimetry were made in order find optimal CH-to-WPI mass ratio for coacervation. maximum turbidity CH:WPI 0.1:1 dispersions CH/WPI (bo...

The characterization of materials supports their development and in particular of superconductors, for their technological applications. Scanning electron microscopy (SEM) is one of these characterization techniques, whose data is used to estimate the properties, determine the shortcomings and hence improve the material. The phenomenon of superconductivity initially develops within the grain an...

The electroless deposition method was used to prepare Ni-based nanocomposite coatings, this approach represents an alternate way of having coatings on the different substrates. Most previous literatures subject and work deals with a study effect process conditions and, Bath composition microstructure at macroscale Ni-Al2O3 composite coatings. Though, step structure bath are little, present aims...

A photocatalyst comprised of Ag nanoparticles dispersed on an anatase matrix has been prepared using a simple hydrothermal method without additional thermal treatment. The material was characterized scanning electron microscopy (SEM), X-ray diffraction (XRD), high-resolution transmission (HRTEM), UV-Vis spectroscopy, and N2 adsorption–desorption isotherms. catalyst activity evaluated by photoca...
