A novel photocatalyst based on TiO2-PANI composite supported on small pieces of cork has been reported. It was prepared by simple impregnation method of the polyaniline (PANI)-modified TiO2 on cork. The TiO2-PANI/Cork catalyst shows the unique feature of floating on the water surface. The as-synthesized catalyst was characterized by X-ray diffraction (XRD), scanning electron micrograph (SEM), t...

Various techniques have been developed to infer the 3D relationship of reciprocal lattice vectors from electron diffraction patterns taken at different specimen orientations. Such relationship is subsequently applied in crystallographic analyses. Due to the transmitted nature of the electron beam, TEM images present 3D information averaged throughout the thickness of the specimen on each microg...

SPHIRE (SPARX for High-Resolution Electron Microscopy) is a novel open-source, user-friendly software suite for the semi-automated processing of single particle electron cryo-microscopy (cryo-EM) data. The protocol presented here describes in detail how to obtain a near-atomic resolution structure starting from cryo-EM micrograph movies by guiding users through all steps of the single particle ...

Peats are geotechnically problematic soil due to their high compressibility and low shear strength. Cement is widely used for the stabilization of peat by deep mixing method (DMM). This paper presents the results of the model study of compressibility property of peats stabilized with cement columns formed by DMM. The results of consolidation test, scanning electron micrographs (SEM) and energy ...

The fine architecture of skeletal muscle Z bands is considered in view of stereo electron microscopical evidence and current biochemical and immunological concepts, and a new Z-band model is proposed. This model is based on a looping, interlinking configuration, within the Z band, of strands which emanate from I-band (actin) filaments of adjacent sarcomeres. Two versions of the model seem prese...

In this paper, crystalline iron-nickel alloy nanostructures were successfully prepared from two cationic pyridinium derivatives as soft templates in solution. The crystal structure and micrograph of FeNi alloy nanostructures were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy, and the content was confirmed by energy-dispersive spectrometry....

The staining of thin sections of Osmium tetroxide (OsO4)-fixed biological materials with the lead hydroxide preparat ion of Watson (5) or with semisaturated solutions of lead subacetate (1) represents a considerable advance in electron microscope technique. The contrast of the image viewed in the electron microscope is so far enhanced that accurate focusing is now possible at appreciably higher...

Figure 2. High-power micrograph (original magnification, 600) of the appendix specimen shows mucosal cells with characteristic cytomegalovirus inclusions (arrow); note the “owl-eye” intranuclear inclusions and granular cytoplasmic inclusions. Figure 1. Low-power micrograph (original magnification, 40) of a longitudinal section of the appendix demonstrates mucosa ulcerated with a lymphohistiocyt...

Functional sensory hair cells in the inner ear have specialised microvilli — stereocilia — which are essential for hearing. The scanning electron micrograph at top shows the normal arrangement of stereocilia bundles on three outer hair cells in the inner ear of a three-day-old mouse. The stereocilia grow to form rows of graded height in a distinctive V-shaped bundle. Recent studies in mice have...

Instrumental analysis of vermicompost with the help of modern technologies provides essential information on its maturity, before it can be used for agricultural application. Nowadays, vermicompost is considered as a promising organic alternative to chemical fertilizers in agriculture and horticulture. The objectives of this review are to summarize the sophisticated instrumental techniques such...
