Xylan has a wide application in different types of fields specifically in coating of pipelines and drug delivery systems. Xylan was extracted from cheap agricultural wastes such as sugarcane bagasse, corncobs, ricehulls, wheat husks by alkaline method. The presence of xylan was confirmed by identifying the functional groups by Fourier Transform Infrared Spectroscopy. The concentration of glucose was analyzed quantitatively by phenol sulphuric acid assay. It was found tha tminimum concentration of glucose was observed as present in the commercial xylan. The extracted xylan was characterized using Scanning Electron Microscopy to determine the morphology. The aim of the study is to compare the efficiency of extraction among various agro- wastes. This study reveals that maximum production of xylan was obtained in sugarcane bagasse when compared with corncobs, rice hulls and wheat husks. The maximum xylan recovery of 67.5% was found from sugarcane bagasse

Analysis of physical evidence in police investigations by electron optical techniques has been performed in several laboratories in recent years. These studies have evolved in stages from exploratory evaluation of the viability of first SEM and then EDA analyses of samples, to extensive programs investigating certain classes of evidence materials, to detailed cataloging of the features and the results of large numbers of individual analyses within a class, to the ultimate test of the techniques, application in criminal investigations. During these studies, the following different general characteristics of the analyses emerged - analyses dependent upon the topography, those dependent upon the composition, and those dependent upon both composition and topography. In the experiences in our investigations (l-3), the number of analyses requiring some information from chemical composition were far greater than originally expected.

Aim and Objective: Formation of the gallbladder stones is a common disease and a major health problem. The present study aimed to identify the structures of the most common types of gallbladder stones using X-ray spectroscopic techniques, which provide information about the process of stone formation. Material and Method: Phase and elemental compositions of pure cholesterol and mixed gallstones removed from gallbladders of patients were studied using energy-dispersive X-ray spectroscopy combined with scanning electron microscopy analysis and X-ray diffraction. Results: The crystal structures of gallstones which coincide with standard patterns were confirmed by X-ray diffraction. Plate-like cholesterol crystals with laminar shaped and thin layered structures were clearly observed for gallstone of pure cholesterol by scanning electron microscopy; it also revealed different morphologies from mixed cholesterol stones. Elemental analysis of pure cholesterol and mixed gallstones using energy-dispersive X-ray spectroscopy confirmed the different formation processes of the different types of gallstones. Conclusion: The method of fast and reliable X-ray spectroscopic techniques has numerous advantages over the traditional chemical analysis and other analytical techniques. The results also revealed that the X-ray spectroscopy technique is a promising technique that can aid in understanding the pathogenesis of gallstone disease.

AbstractIn this work, weddellite and sylvite crystals are identified for the first time on the involucral bracts and petals of Xeranthemum annuum and Xeranthemum cylindraceum using scanning electron microscopy coupled with energy dispersive spectrometric (SEM-EDS) analysis. Well-developed crystals of weddellite (CaC2O4·2H2O) occur in the form of a tetragonal bipyramid (hhl), rarely in combination of a bipyramid and tetragonal prism (h00). Indumentum of involucral bracts of X. cylindraceum consists of nonglandular and glandular trichomes. Sylvite (KCl) crystals are observed only on the petal surface of X. cylindraceum. The crystals of sylvite occur in the form of perfect cubes (hexahedrons), but some crystals are deformed, i.e., partially elongated. Taxonomic significance of investigated microcharacters as well as the use of SEM-EDS analysis in taxonomic studies of plants are discussed.
