Antioxidative Activity ofChitosan, Chitooligosaccharidesand Their Derivatives
Chitin is a naturally abundant mucopolysaccharide distributed in the shell of crustaceans, in the cuticle of insects, and also in the cell wall of some fungi and microorganisms. Chitin consists of 2-acetamido-2-deoxy-(1-4)-β-d-glucopyranose residues (N-acetyl-d-glucosamine units) that has intra-and intermolecular hydr…
The Use of Various Typesof NMR and IR Spectroscopyfor Structural Characterizationof Chitin and Chitosan
Oligomers and polymers of chitin and chitosan are homo-polymers or hetero-polymers of two monosaccharides [β-(1-4)-2-acetamido-2-deoxy-d-glucose (GlcNAc); and β-(1-4)-2-amino-2-deoxy-dglucose (GlcN)], which are joined by glycosidic linkages. Oligosaccharides are generally dened as carbohydrate polymers containing a fe…
Chitosan Scaffolds forBone Regeneration
The chitins and chitosans of various origins and some of their derivatives obtained by chemical or enzymatic means are today protagonists in the scenario of wound healing, tissue engineering, and gene therapy, thanks to their outstanding properties. Basic information on these polysaccharides, relevant to the title top…

Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Pu…
Electrostatic Propertiesof Chitosan
Chitosan is a natural polysaccharide possessing biocompatible and biodegradable (Muzzarelli 1997, Muzzarelli and Muzzarelli 2002) properties. It has received great attention from researchers due to its wide application in medical and pharmaceutical elds. Its favorable intrinsic properties and highly abundant natural r…
Chemical Modificationsof Chitosan Intended forBiomedical Applications
Chitosan, α (1-4) 2-amino 2-deoxy β-d glucan, possess structural characteristics similar to glycosaminoglycans. This polycationic biopolymer is generally obtained by alkaline deacetylation of chitin, which is the main component of the exoskeleton of crustaceans, such as shrimps (Muzzarelli 1973). Chitosan displays int…
Mechanism and Applicationof Chitin/Chitosan and TheirDerivatives in Plant Protection
Although chitin was isolated by Braconnot in 1811 for the rst time from the cell walls of mushrooms, and chitosan was found in 1894 by Hoppe-Seyler, they remained unused biological resources for more than 100 years. However, interest in these abundant carbohydrates increased rapidly from the 1960s. The enormous increa…
Chitin/Chitosanand Derivatives forWastewater Treatment
Water is a scarce resource. Only 0.03% of the world’s water reserves are available for human activities. Population growth and industrial boom have increased the demand for water, while supply has remained constant. Moreover, inappropriate water management has reduced the amount of available resources (Allegre et al.…
X-Ray Diffraction Studiesof Chitin, Chitosan, and Their Derivatives
Scattering is a powerful analytical method that can be used to determine the structure and dynamics of a range of “soft” materials like colloids, polymers, proteins, etc., using x-rays, neutrons, electrons, or visible light. X-ray crystallography (also called x-ray diffraction) is the most straightforward method of de…
Role of interface reaction on resistive switching of Metal/a-TiO2/Al\n RRAM devices
For the clear understanding of the role of interface reaction between top\nmetal electrode and titanium oxide layer, we investigated the effects of\nvarious top metals on the resistive switching in Metal/a-TiO2/Al devices. The\ntop Al device with the highest oxygen affinity showed the best memory\nperformance, which i…
A Variational Deduction of Second Gradient Poroelasticity II: An Application to the Consolidation Problem
The second gradient model of poromechanics, introduced in Part I, is here linearized in the neighborhood of a prestressed reference configuration to be applied to the one-dimensional consolidation problem originally considered by Terzaghi and Biot. Second gradient models allow for the description of boundary layer eff…
Heapable Sequences and Subsequences
Let us call a sequence of numbers heapable if they can be sequentially inserted to form a binary tree with the heap property, where each insertion subsequent to the first occurs at a leaf of the tree, i.e. below a previously placed number. In this paper we consider a variety of problems related to heapable sequences a…
Electrode Placement and the Fabrication of Sub-100-nm Nanopore Arrays
The anodization of aluminum films grown on silicon substrates under controlled\nconditions is used to fabricate porous alumina arrays. Such porous arrays are used as\nsensors or lithography masks for fabrication of sub-100-nm nanodot arrays. The selfassembly\nof these pores into ordered arrays is determined by anodiza…
Preparation, characterisation and diffusion studies ofpolypyrrole, poly(1,6-di(N-pyrrolyl)hexane) and poly(N-dodecylpyrrole)
Polypyrrole and its derivatives are important conductive polymers with potential applications in energy storage and electrochromic displays. Their performance depends on the polymer morphology and the diffusion rates of mobile ions in the solid polymers. We report the diffusion coefficients of various dopant counter-a…

Transport Properties of Nanocomposites
Transport Properties of Nanocomposites were studied in this work. A Monte\nCarlo technique was used to model the percolation behavior of fibers in a\nnanocomposite. Once the percolation threshold was found, the effect of fiber dimensions\non the percolation threshold in the presence and absence of polymer particles wa…
