This document presents a study on using an electroactive polymer and a green inhibitor from orange fruit waste to prevent corrosion of mild steel in seawater. The study aims to analyze corrosion of mild steel electrodes using open circuit potential and electrochemical impedance spectroscopy techniques. Literature research found that polypyrrole has shown potential but varying success as a corrosion inhibitor. Orange fruit waste and ascorbic acid have also shown promise as green inhibitors. The expected results are that open circuit potential graphs will show increased protection over time, and Nyquist, Bode, and phase plots will identify resistive elements indicating reduced corrosion rates. The study seeks to determine if the proposed green inhibitor performs better than the electroactive polymer at inhibiting corrosion in deepwater
Nanoparticles Methods for Nanoparticles Synthesis Overviewijtsrd
Nanoparticles exist in several different morphologies such as spheres, cylinders, platelets, tubes etc. The word nanoparticles are used to describe a particle with size in the range of 1nm to 100nm, at least in one of the three possible dimensions. In this size range, the physical, chemical and biological properties of the nanoparticles changes in fundamental ways from the properties of both individual atoms molecules and of the corresponding bulk materials. The enormous diversity of the nanoparticles arising from their wide chemical nature, shape and morphologies, the medium in which the particles are present, the state of dispersion of the particles and most importantly, the numerous possible surface modifications the nanoparticles can be subjected to make this an important active field of science now a days.

Synthesis and characterization of zno thin films deposited by chemical bath t...eSAT Journals
Abstract ZnO thin films have been deposited on silica glass substrate using the chemical bath deposition technique. The precursors used were zinc chloride and aqueous ammonia. The solution was stirred continuously with the help of a magnetic stirrer at a bath temperature of 70 oC and a deposition time of 70 minutes. The elemental composition and the surface morphology were studied using energy dispersive and scanning electron microscopy. The band gap was 2.72, 2.66, 2.60 eV for as-deposited, annealed at 200 oC and 300 oC respectively. There was a red shift in the band gap energy as the annealing temperature was increased. This might be due to an improvement in the crystallinity of the ZnO thin films. Index Terms: Zinc oxide, chemical bath, band gap, annealing
The document summarizes the synthesis and characterization of ZnO thin films deposited by chemical bath deposition technique. ZnO thin films were deposited on silica glass substrates in a chemical bath containing zinc chloride and ammonia at 70°C for 70 minutes. Elemental composition analysis using EDAX confirmed the formation of ZnO. SEM images showed the films had a nanorod morphology. The band gap was determined to be 2.72 eV for the as-deposited film and decreased to 2.66 eV and 2.60 eV for films annealed at 200°C and 300°C, respectively, due to improved crystallinity.

Title: ALD Technology – Introduction, History & Principles
Abstract: This tutorial keynote will introduce atomic layer deposition (ALD) – a variant of chemical vapor deposition - and fundamental principles and concepts related it from a generic viewpoint applicable to any ALD process and reactor. The early history and current usage of ALD are briefly overviewed: who made the first experiments, when, and why? How has the view on the history of ALD evolved? Where is ALD now used, by whom, and why? ALD relies on repeated chemical adsorption steps from gas phase to surface. The status of understanding the adsorption steps of ALD films will be presented and discussed using mainly the archetype trimethylaluminium-water ALD process as example and 3D conformality modelling as additional vehicle. Plenty of links to further sources of information will be included in this keynote presentation.

Mild steel a low carbon steel is an affordable engineering material used for many purposes in various environments including mild acidic environment with some precautions. The corrosion behaviour of mild steel MS in 0.5 M H2SO4 and 0.5 M HCl, in the temperature range 303–323 K without and with the inhibitor N 3,4 dimethoxyphenyl methyleneamino 4 hydroxy benzamide DMHB , was investigated using Potentiodynamic polarization and Electrochemical impedance spectroscopy EIS techniques supplementing with surface characterization study using scanning electron microscope SEM and atomic force spectroscopy AFM . Experimental observations were found to be in agreement with Density functional theory DFT calculations. The inhibition efficiency increases with increase in DMHB concentration and showed maximum inhibition efficiency of 86 in 0.5 M H2SO4 and 81 in 0.5 M HCl, respectively, at concentration of 3 × 10 3 M at 303 K. The inhibition efficiency of DMHB obtained relatively at its lower concentration 3 × 10 3 M compared to other reported related compounds confirms its potential towards corrosion inhibition.
