Studies on the cellulose-binding domains adsorption to cellulose.
Cellulose-binding domains (CBD) are modular peptides, present in many glycanases, which anchor these enzymes to the substrate. In this work, the effect of CBD adsorption on the surface properties of a model cellulose, Whatman CF11, was studied. The methods applied include inverse gas chromatography (IGC), ESCA, X-ray diffraction, and scanning electron microscopy (SEM). The CBD partition affinit...
متن کاملstudies on nano barium strontium titanate/cellulose derivatives composites
studies were carried out on the preparation and properties of the composites made from cellulose acetate butyrate and cellulose acetate propionate with various amounts of barium strontium titanate nano-particle. the nano-particles of barium strontium titanate (bst) with formulation of ba0.77sr0.23tio3 were made by sol-gel method and their purity and particle size were analyzed by x-ray diffract...
متن کاملStudies on Sarcina ventriculi. III. Localization of cellulose.
Suringar (1866) and Smit (1930) reported that cell packets of Sarcina ventriculi exhibited a positive cellulose reaction (stained red to purple) when suspended in an aqueous solution containing ZnC12, 12, and KI. These workers believed that cellulose was localized in the cell wall. On the other hand, Delaporte (1957) could not obtain this color reaction and reported that examination of S. ventr...
متن کاملStudies of Electrospun Cellulose Acetate Nanofibrous Membranes
The objective of this work was to study the feasibility of preparing cellulose acetate (CA) nanofibrous membranes by electrospinning with single solvent and their potential applying as affinity membrane. CA solutions in dichloromethane (DCM), formic acid, acetic acid and trifluoroacetic acid (TFA) were electrospun into nonwoven fiber membranes, respectively. The scanning electron microscope (SE...
متن کاملInterfacial Studies of Cellulose Whisker Polymer Nanocomposites
The molecular deformation of cotton cellulose whisker/epoxy resin (CW/EP) and tunicate whisker/poly(vinyl) acetate (TW/PVAc) composites were investigated using Raman spectroscopy. A shift in the 1095 cm Raman peak position is recorded for samples deformed in both tension and compression, which corresponds to the molecular deformation of the cellulose chains within the whiskers. Cyclic molecular...
