Polyaramides, such as Kevlar, are of great technological importance for their extraordinary mechanical performance. As fibers, they used in personal safety, reinforcement tires and ropes, further material composites that require extreme stability. However, the properties polymer depend on environmental conditions. Specifically, elevated temperatures and/or irradiation with UV light seriously affect its toughness. Classical approaches to protect polyaramide fibers from these external factors...
Graphene is an attractive material for its physicochemical properties, but many applications only chemically synthesized forms such as graphene oxide (GO) and reduced (rGO) can be produced in sufficient amounts. If considered electrode material, the intrinsic defects of GO or rGO may have negative influence on conductivity electrochemical properties. Such are commonly oxidized sites that offer possibility to functionalized with other materials order improve performance. In this work, we...
This paper describes the design, implementation and validation of a sensitive integral technology solution for endotoxin detection. The unified portable platform is based on electrochemical detection endotoxins using synthetic peptide immobilized thin-film biosensor. work covers fabrication an optimized sensor, biofunctionalization protocol design measuring signalling elements (a microfluidic chamber potentiostat-galvanostat), framed ad hoc this specific application. use technologies to...
In this paper, the implementation and characterization of a hand-held simple biosensor for in-situ endotoxin determination are described. The integrated developed here is based on electrochemical detection using polymyxin B as bioreceptor immobilized onto gold electrodes via self-assembled monolayer. cyclic voltammetry, impedance spectroscopy, atomic force microscopy were used to characterize performance properties throughout functionalization process. addition, comparative analysis behavior...
Abstract. In this paper an electrochemical endotoxin biosensor consisting of immobilized lipopolysaccharide (LPS) ligand, polymyxin B (PmB), is presented. Several parameters involved both in the device fabrication and detection process were analyzed to optimize ligand immobilization interaction between PmB LPS, aiming at increasing sensitivity sensor. Different pre-treatment procedures as well functionalization methods studied evaluated. The use a SAM (self-assembled monolayer) immobilize...
Abstract A combination of atomic layer deposition and photolithography is applied to fabricate interdigitated electrodes aluminum‐doped zinc oxide embedded in polyethylene terephthalate substrates. Various designs with different gap widths ratios are realized important characteristics the electrodes, including thickness, surface roughness, electrical properties ZnO:Al 2 O 3 studied. Oxygen plasma etch embed a methodology which breakthrough toward ultimately thin devices fabrication....
Reflective surfaces are one of the key elements solar plants to concentrate energy in receivers thermal electricity plants. Polymeric substrates being considered as an alternative widely used glass mirrors due their intrinsic and processing advantages, but optimizing both reflectance physical stability polymeric still poses technological difficulties. In this work, have been functionalized with ceramic thin-films by atomic layer deposition. The characterization optimization parameters...
Electrochemical Impedance Spectroscopy (EIS) studies of two different ionogels (IOs) are performed using gold interdigitated electrodes (Au-IDEs). Poly(N-isopropylacrylamide) (pNIPAAM) is polymerized in the presence ionic liquids (ILs), ethyl-3-methylimidazolium ethyl sulfate [C2mIm][EtSO2] (1) or trihexyltetradecyl-phosphonium dicyanamide [P6,6,6,14][DCA] (2). The Nyquist diagrams IOs reflect significant differences due to their polarity and porosity dissimilarities. This fact supported...
