Degradation mechanism

natural fiber for the construction of hybrid bio-composites. In the current research project, a thorough analysis of the use of soy-PF resin for the creation of composites reinforced with jute was conducted. A novel and practical cutlery material was created after the mechanical properties were evaluated and optimized. In order to study the value addition of these newly proposed biocomposite materials as an ecological alternative in terms of natural resources versus synthetic resources, variables such as hardness, cytotoxicity, and degrading qualities of composites were also explored.

In the present study, for the first time, photodegradation of lindane compared with adsorption technique in water environment using synthesized TiO2-NPs was investigated. Some effective parameters for lindane removal by photocatalyst were systematically optimized. The mechanism of lindane removal using TiO2-NPs is also suggested on the basis of degradation kinetic and the change in surface charge.

The article reports upon the preparation and characterization of organo-functionalized NieAl layered double hydroxide (LDH)-polystyrene (PS) nanocomposites. Initially, pristine NieAl LDH was synthesized via the co-precipitation technique and was subsequently treated using sodium dodecyl sulfate to obtain organo-functionalized NieAl LDH (ONieAl LDH).

The research describes in the most general way the system of public non-business units in the field of culture and sports in Ho Chi Minh City; assess the achieved results, difficulties and problems facing units in the process of implementing financial institutions. Some difficulties and problems that the units are facing are: not being assigned full autonomy, only financial autonomy; degraded material foundations cannot afford to invest in new construction, renovation or repair by themselves; subject to fierce competition from private service providers.

Procedures for chitin nanofiber or nanocrystal extraction from Crustaceans modify the chitin structure significantly, through surface deacetylation, surface oxidation and/or molar mass degradation. Here, very mild conditions were used to disintegrate chitin fibril bundles and isolate low protein content individualized chitin nanofibers, and prepare nanostructured high-strength chitin membranes.

The aim of the work "Stochastic service life prediction of RC girders subjected to chloride induced corrosion – Shear limit state" presented in this thesis is service life prediction of corroded reinforced concrete girders, which forms an important part of durability design. The scope of this work is limited to shear limit state considering the chloride induced corrosion of reinforcement as the degradation mechanism. The review of literature shows that the service life estimation of reinforced concrete bridges exposed to marine environment is an active area of research.

A major objective of the research presented here is to develop a link between the two approaches by establishing the relationship between the bridge component condition and the capacity and serviceability limits of the structure. A comprehensive review of literature identified methods of predictive modelling of bridge component condition change using different approaches. The review also indicated that a key to the proposed linkage is considering specific degradation mechanisms in predicting bridge deterioration.
