Large volume changes (∼300%) during cycling and low electronic conductivity of silicon (Si) always lead to the failure of the Si anode for lithium-ion batteries. In this paper, we report a facile method to fabricate Si/Ti3SiC2 composites by one-step sand-

Scanning Electron Microscopy: Preparation and Imaging for SEM
2012Scanning electron microscopy (SEM) has been almost universally applied for the surface examination and characterization of both natural and man-made objects. Although an invasive technique, developments in electron microscopy over the years has given the microscopist a much clearer choice in how invasive the technique will be.

Study of the morphology of the polyacetylene by scanning electron microscopy (SEM)
Synthetic Metals, 2001The microscopic morphology of polyacetylene (PA) film has shown a number of criteria that allow to define the optimal conditions of polyacetylene synthesis of a highly fibrillar morphology, these are : Aging time and aging of temperature, temperature of polymerization, pressure of acetylene, concentration of catalyst, molar ratio and electron donors.

This chapter describes laboratory protocols for TEM and SEM approaches allowing the examination of the dental hard tissues' constituents at the ultrastructural level. TEM has the highest resolution power to examine the cellular and extracellular matrix ultrastructure inside a given sample, detecting the presence, location, and quantification of ...

A protocol for isolation and visualization of yeast nuclei by scanning electron microscopy (SEM)
Nature Protocols, 2007This protocol details methods for the isolation of yeast nuclei from budding yeast (Saccharomyces cerevisiae) and fission yeast (Schizosaccharomyces pombe), immuno-gold labeling of proteins and visualization by field emission scanning electron microscopy (FESEM). This involves the removal of the yeast cell wall and isolation of the nucleus from within,

Scanning electron microscopy (SEM) of some Setaria species (Filarioidea, Nematoda)
Zeitschrift f�r Parasitenkunde, 1977Some Setaria spp., such as S. digitata, S. marshalli, S. marshalli pandei, S. equina and S. labiatopapillosa were studied by scanning electron microscopy at the critical points in the anterior and posterior parts of the adult worms. The amphids, Deirids, find transverse striations of the cuticle and phasmidial pare, as well as the transverse bands ...

Determination of the biocompatibility of biomaterials by scanning electron microscopy (SEM)
2008Scanning electron microscopy is an excellent method to determine the biocompatibility of biomaterials. With the possibility of showing the surface of biomaterials and measuring the surface properties of the material of interest like surface roughness, fins on bone implants or homogeneity of surface layers this method has also the potential to show the ...
