Requirements Basic understanding of corrosion processes (anodic and cathodic reactions, corrosion current) Basic understanding of corrosion electrochemistry Basic understanding of electrical concepts such as voltage, current and resistance Description In this course, we will take a practical approach to understanding and using electrochemical impedance spectroscopy (EIS) for corrosion measurement and analysis. We will begin by covering the basics of EIS, discussing essential concepts like impedance, alternating current signals, and corrosion surface phenomena, all aimed at making EIS accessible and straightforward for everyone, and we will finish with a practical example of fitting a complex EIS spectrum.In Section 1, we will learn about the fundamentals of corrosion and impedance in electrochemical systems, building the foundation for understanding how and why EIS is applied to corrosion studies. In Section 2 we will look at how the processes occurring on the surface impact on the EIS responses, considering key factors like polarization resistance, double layer capacitance, and the impact of surface coatings on the EIS response.In Section 3, we will focus on practical considerations for measuring EIS spectra. We will discuss critical topics such as the selection of signal amplitude, the measurement frequency range, and the importance of stationarity to obtain reliable results. Finally, in Section 4, we will learn how to interpret EIS spectra using equivalent circuit models, exploring characteristic responses and fitting techniques to extract valuable information from the data.By the end of the course, we will have the knowledge and skills needed to confidently measure, model, and interpret EIS data for effective corrosion analysis.

How are we measuring circular dichroism and introduction various parameters. Circular dichroism of proteins Circular dichroism of DNA Additional learning on Ramachandran plot of proteins Requirements No previous skills are required Enthusiasm to learn biology and techniques related to biology, biochemistry and organic chemistry Description The major issues with the courses on spectroscopy are inclusion of too much instrumentation, electronics, mathematical calculations, and very less discussion on data analysis. This course on UV-Visible spectroscopy and circular dichroism spectroscopy for the students is for the students who want to learn the basic aspects and the data analysis by using so many examples. This course will be teaching about two major and important techniques related to biology and organic chemistry that is UV visible spectroscopy and circular dichroism spectroscopy. It is a perfect introductory course for the students which starts its journey with discussion on basic concept of visible spectroscopy and it tells you about how different organic molecules with double bonds, with conjugated systems, and with lone pairs are interacting with light. Then it starts discussing about different examples of UV visible spectroscopy data analysis with the help of graphs. In the third section, it talks about circular dichroism by starting with types of light and what is actually circular dichroism. Then it tells you how we are measuring CD, circular dichroism, what is ellipticity, basic formulas, basic discussion of fundamentals, and basic mathematics of CD. Then it goes on and talks about circular dichroism of proteins by taking 3 to 4 examples. Then finally, the third section ends with circular dichroism of DNA.

Clinical MR Spectroscopy: Techniques and Applications English | 274 pages | ISBN: 052186898X | PDF | 9 Mb In vivo magnetic resonance spectrosopy (MRS) is increasingly being used in the clinical setting, particularly for neurological disorders. Clinical MR Spectroscopy - Techniques and Applications explains both the underlying physical prin[beeep]les of MRS and provides a perceptive review of clinical MRS applications. Topics covered include an introduction to MRS physics, information content of spectra from different organ systems, spectral analysis methods, recommended protocols and localization techniques, and normal age- and region-related spectral variations in the brain. Clinical applications in the brain are discussed for brain tumors, hypoxic and ischemic injury, infectious, inflammatory and demyelinating diseases, epilepsy, neurodegenerative disorders, trauma and metabolic diseases. Outside of the brain, techniques and applications are discussed for MRS in the musculosketal system, breast and prostate. Written by leading MRS experts, this is an invaluable guide for anyone interested in in vivo MRS, including radiologists, neurologists, neurosurgeons, oncologists and medical researchers.
