Research-Industry Collaboration: Is it good to rely on setpoints derived through lab based research programs to characterize real world (industries) situations?

Reliability of research activities depends on many factors. It will vary from sector to sector. If the reliability is in question, what should be the best possible way of establishing a meaningful setpoint relationship between research and real world application?

Korea - Corrosion Research and Modelling - Advanced method for the development of an empirical model to predict time-dependent corrosion wastage

Advanced method for the development of an empirical model to predict time-dependent corrosion wastage

Abstract

In this paper, an advanced method for the development of an empirical model to predict time-dependent corrosion wastage is proposed. It is well recognised that the statistical scatter of corrosion wastage at any exposure time is generally very wide, and the reliability of a corrosion model thus relies on how accurately such scatter is measured. In the proposed method, the statistical scatter of corrosion wastage at any exposure time is analysed in a refined manner and formulated using the Weibull function. Both the shape and scale parameters of the Weibull function are determined as a function of time through the curve fitting of a corrosion measurement database. An application of the proposed method’s use in the development of an empirical model for the seawater ballast tank structures of aged ships is presented. Its ability to generate an empirical corrosion model is confirmed, thus making it possible to predict time-dependent corrosion wastage more accurately.

US - Networks of Diasporas in Engineering and Science (NODES) Fact Sheet; India - We CAN Control Corrosion in India is an example Science and Technology Diaspora Network

Article Source: Networks of Diasporas in Engineering and Science (NODES) Fact Sheet
Publication Date: July 2012

As President Obama has said, we will “harness the power of science to achieve our goals — to preserve our environment and protect our national security; to create the jobs of the future, and live longer, healthier lives.” Part of harnessing that power of science requires working closely with science diaspora networks that have the potential to be significant partners in development strategies and international cooperation efforts. In an age of increased mobility and connectivity, these knowledge diaspora networks include scientists, students, innovators and entrepreneurs, as well science policy experts that are working outside of their country of birth, speaking a common language and building partnerships. Scientific diasporas are an integral part of our “whole-of-society” science diplomacy strategy, helping to build knowledge-and innovation-based societies around the world and to spread scientific values such as meritocracy and transparency that support economic growth and democracy.


Networks of Diasporas in Engineering and Science or NODES, is a joint effort of the U.S. Department of State’s Office of the Science and Technology Adviser to the Secretary, the American Association for the Advancement of Science (AAAS) and the National Academy of Sciences to assist science diasporas in partnership with U.S. Government technical agencies, academia and science and technology focused non-government groups. Existing activities and networks will be leveraged to help diaspora groups identify and communicate with interested participants, understand how to influence effective policies and connect their talent with the needs of their countries of origin. NODES will highlight the contributions of science diasporas to the United States and to the development of their ancestral countries of origin through research, innovation and education partnerships. A yearly gathering at the AAAS annual meeting will serve as an anchor for mobilizing new constituencies, catalyzing new capacity-building activities and sharing resources in partnership with the International Diaspora Engagement Alliance (IdEA).

Abstract

The paper is devoted to studying the possibility of application of tributylamine (TBA) as volatile inhibitor of hydrogen sulfide corrosion (HSC) of steels. The influence of С(H2S), pH and temperatures on TBA protective action is studied as well. Amine adsorption on steel surface modified by sulfide has been investigated and TBA impact on its composition and structure has been reviewed using a number of electrochemical methods, ellipsometry and XPS. The contributions of corrosion products and inhibitor films to the total protective effect have been estimated on the basis of the developed method.

Highlights

► Tributylamine is studied as volatile inhibitor of steel H2S-corrosion. ► Amine adsorption on air oxidized and sulfide modified steel surface is considered. ► Change of surface layers composition under corrosion inhibition is detected using XPS. ► Method for estimating films contributions to the total protection is offered. ► Amine influence on sulfide film cracking is discussed using the developed method.

Republic of Korea - Corrosion Research - Effect of nitrite concentration on the corrosion behaviour of carbon steel pipelines in synthetic tap water

Effect of nitrite concentration on the corrosion behaviour of carbon steel pipelines in synthetic tap water

Abstract

This study examines the effect of the continuous decrease of the nitrite concentration on the corrosion properties of a carbon steel pipeline in deaerated synthetic tap water. Passive film, which is composed mainly of maghemite (γ-Fe2O3), was formed in synthetic tap water containing 200 ppm nitrite. A carbon steel pipeline in synthetic tap water containing 100 ppm nitrite was more susceptible to localised corrosion than that containing 50 ppm nitrite due to the effect of the small anode and large cathode area. Uniform corrosion dominates in synthetic tap water containing 50 ppm nitrite.

Highlights

► Corrosion resistance of the carbon steel pipeline was improved by adding nitrite. ► Passive film was formed in synthetic tap water containing 200 ppm nitrite. ► Localised corrosion dominates in synthetic tap water containing 100 ppm nitrite. ► Uniform corrosion dominates in synthetic tap water containing 50 ppm nitrite. ► To protect the pipelines, the minimum dosage of nitrite inhibitor is 200 ppm.
