Influence of a Porous Corrosion Product Layer on the Corrosion Phenomenon of Carbon Steel Pipelines

M. Mohamed-Saïd [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Assessing the severity of the internal corrosion of structures is of paramount importance in the oil & gas industry. Modelling and simulation of this process proved to be key techniques to understand its mechanism and the main factors influencing its severity [1-4]. Considerable ... En savoir plus

Efficient Heat Management Technique for Electronic Display Device

U. Shukla[1], and D. Gupta[1]
[1] Department of Materials and Metallurgical Engineering, Indian Institute of Technology Kanpur, Uttar Pradesh, India

One of the major challenges faced by the semiconductor industry is that electronic circuits produce a lot of heat energy during their operation. And with the current scenario where the gates are packed so much close together, then the problem of heat generation has become extremely ... En savoir plus
