چکیده تحقیقات در این پروژه به دو بخش، پیش بینی بازدارنده های خوردگی و مدل سازی مکانیسم واکنش تقسیم می شوند. در قسمت اول، درصد بازدارندگی مشتقات ایمیدازول در سطح فولاد نرم در محیط هیدروکلرید اسید را مورد مطالعه قرار گرفت. خوردگی، تخریب فلزات توسط واکنش های شیمیایی و الکتروشیمیایی تحت تاثیر محیط اطراف می باشد. بنابراین، جنبه های گوناگونی باید برای محافظت ویا کاهش این فرآیند به کار برده شود. در م...

This review explores the question whether chemometrics methods enhance the performance of electroanalytical methods. Electroanalysis has long benefited from the well-established techniques such as potentiometric titrations, polarography and voltammetry, and the more novel ones such as electronic tongues and noses, which have enlarged the scope of applications. The electroanalytical methods have...

What we mean with chemometrics is closely connected to what we want from it, our idealized view of chemistry, data, statistics, models, and what not. Personally, I have a fairly clear opinion of what I mean with, and what I want chemometrics to be. Of course, this view is based on my experience in academic and industrial chemistry, and I shall here try to explain these views, and the chemical a...
