Percent crystallinity values showed a gradual decrease throughout the experiment. incrassata by the fourth week of decay, followed by a slow decrease. Results showed an increase in crystallite width by M. Pellets were analyzed by x-ray diffraction using a θ-2θ scan and the resulting spectra were deconvoluted to determine average crystallite width and overall percent crystallinity. After removal from the jars, wood blocks were dried, analyzed for weight loss, ground into powder and pressed into pellets. Fungi were grown in modified soil block jars with spruce wood blocks for 2, 4, 6 and 8 weeks. Studies were conducted to determine changes over time in wood crystallinity generated by the brown rot fungus Meruliporia incrassata and the soft rot fungus Chaetomium elatum. Enhanced understanding of the mechanisms and effects of wood degradation through x-ray diffraction may improve knowledge of degradative processes and facilitate the development of more effective decay prevention measures. In wood, this process has been used to determine among other things the average width of the cellulose microcrystals, the percent of crystalline cellulose within the wood, and can be used to examine the changes in these parameters during degradation. Technol.X-ray diffraction (XRD) is based on the creation of an interference pattern by x-rays when they encounter a regularly spaced matrix. 33 816 (2010)ī Mallick, T N Tiwari, S Panigrahi and R C Behera Meas.

J C Bose Researches on Irritability of Plants (London: Longmans Green) (1913) It is expected that the present study may help to analyse the X-ray diffraction of fibre materials in general and natural fibres in particular. The smallest crystallite sizes observed in both parallel and perpendicular mounting are 18.78 and 30.78 Å respectively. The I max of cellulose-I has been observed along (002) and \((10\overline\). The effect of the fibre structure and its orientation due to different mounting have been investigated using X-ray diffraction technique. The diffraction pattern of the fibre is found out to be cellulose-I. pudica fibre has been extracted from the stem of the herb by sinking the stem in 10% NaOH solution for one week. pudica fibre using diffraction technique. So far as our knowledge is concerned there is no report on the X-ray structure of M. Because of its electro-active sensing nature, it has been found very interesting among physicists, chemists, biologists, material scientists and technologists. Sensitive plant ( Mimosa pudica Linn.) fibre is a natural fibre with electrically conductive property.
