Corrosion is a material deterioration process due to chemical interactions with surrounding environment. Metallic components of amphibious vehicles are exposed to aggressive species such as chlorine in marine environment. These components must be coated or well protected to inhibit corrosion. Peeling and cracked paint on the surfaces of the vehicle hulls may result in undesired chemical interactions on damaged areas. Cathodic protection application with sacrificial anodes is an effective solution to corrosion of steel components in direct contact with seawater. The scope of this study covers investigation of corrosion kinetics for selected steel types and determination of appropriate cathodic protection system for steel components of amphibious vehicles. Steel samples were subjected to accelerated corrosion tests in artificial seawater. Electrochemical data were obtained by potentiostatic test techniques. The data were then introduced to COMSOL Multiphysics modeling software as input parameters for cathodic protection simulation. Potential and current density distributions in seawater were evaluated to design the cathodic protection system. In order to enhance homogenous protection performance, VDFULILFLDODQRGHV¶dimension, quantity and positions were optimized.


Metal Oxides Supported Cobalt nanoparticles: Active Electrocatalysts for Oxygen Evolution Reaction
Önal, Ahmet Muhtar; Akbayrak, Merve (2021-08-01)
Besides precious metal oxides, non-noble metal oxides are found to be promising materials especially, in the alkaline medium for OER. In this work, Co/MO 2 (M = Ti, Zr, and Ce) catalysts were synthesized with- out using any harsh steps such as pyrolization, annealing, calcination, and carbonization. Cobalt nanopar- ticles with ∼2.6 nm particle size were loaded on metal oxides by simple impregnation and reduction method. Considering the low onset and overpotential values, low Tafel slopes, high exchange curr...
Isotropic-Kinematic Cyclic Hardening Characteristics of Plate Steels
Shakeri, Ashkan (Springer Science and Business Media LLC, 2017-03-01)
Cyclic hardening of metals is considered as one of the most important features that affects extremely the hysteresis behavior of steel structures. One approach to study this characteristic is dividing it into two components, including isotropic hardening and kinematic hardening, and defining any of these components for any type of metals by calibrated data obtained from experiments. However, the lack of these calibrated data on metals, restricts this approach. Therefore, in this paper the isotropic and kine...
Enantioselective michael addition of 1-nitropropane to nitroolefins with 2-aminodmap and quinine based bifunctional organocatalysts
Kanberoğlu, Esra; Tanyeli, Cihangir; Department of Chemistry (2015)
1,3-dinitro compounds are key materials in the synthesis of a variety of important fine chemicals. Moreover, they are reduced to 1,3-diamines which are starting materials of biologically active compounds, agrochemicals and pharmaceuticals. In this study, ((2S,3S)-1,3-dinitropentan-2-yl)benzene was synthesized via the Michael addition of 1-nitropropane to trans-β-nitrostyrene in the presence of chiral bifunctional 2-aminoDMAP and quinine based organocatalysts. In the first part of study, reaction conditions ...
Non-fickian moisture absorption in polymers coated with a thin nanocomposite layer

Moisture absorption in polymers and polymeric composites is well known to lead to significant degradation in mechanical properties. Most epoxy based composites may absorb 2 to 5 wt.% moisture when they are subjected to humid environments. Moisture absorption in polymers has been often characterized with Fickian or various non-Fickian models to describe the time-dependent absorption phenomena. Previous experiments have shown that dispersing moderate amounts of nanoclay in an epoxy resin can: (i) reduce the t...
Atmospheric global dust cycle and iron inputs to the ocean
Mahowald, NM; Baker, AR; Bergametti, G; Brooks, N; Duce, RA; Jickells, TD; Kubilay, N; Prospero, JM; Tegen, I (American Geophysical Union (AGU), 2005-12-30)
Since iron is an important micronutrient, deposition of iron in mineral aerosols can impact the carbon cycle and atmospheric CO2. This paper reviews our current understanding of the global dust cycle and identifies future research needs. The global distribution of desert dust is estimated from a combination of observations of dust from in situ concentration, optical depth, and deposition data; observations from satellite; and global atmospheric models. The anthropogenically influenced portion of atmospheric...
