Recent Corrosion Inhibitors for Pure Lead (Pb) in 1M Acetic Acid Solution | Chapter 1 | Chemical and Materials Sciences: Developments and Innovations Vol. 7

Lead (Pb) undergoes rapid corrosion in the presence of acetic acid. Inhibited acetic acid is used during this study to prevent corrosion of pure lead (Pb). Brilliant cresyl blue (BCB), Mordant orange 37 (MO) and Crystal violet (CV) are used as effective corrosion inhibitors.  The behavior of lead in 1 M acetic acid solution in case of the presence and absence of the selected dyes has been investigated, using weight loss measurements, open-circuit potential measurements and potentiodynamic polarization measurements techniques. The inhibition efficiency was increased with an increase in inhibitor concentration. Polarization measurements reveal that BCB has a maximum value of IE was 73% at 1x10^-1 %. From the results, it is found that all techniques are in good agreement and the values of inhibition efficiency are dependent upon the concentration and chemical structure of dyes. The study concluded that the investigated dyes were good corrosion inhibitors for pure lead in 1 M acetic acid solution. The lead corrosion inhibition efficiency of the investigation dyes in 1M acetic follows the order: BCB dye> MO dye > CV dye.

Molecular Sociology: Integrating Philosophy of Science, Psychology and Community | Chapter 2 | Research Trends and Challenges in Medical Science Vol. 6

 In an effort by the author to derive a new branch of sociology, this chapter introduced a new definition, "Molecular Sociology." The consequence of the author's numerous publications led him to think of molecular sociology as a new branch of sociology. These studies have extensively examined human behavioural initiatives and motives that can not be readily described according to current theories. We have taken into account that human behaviour is a dynamic phenomenon and can not be imposed in one frame. We have shown through many studies that molecular sociology contains molecular modifications that can be linked to violent behaviours. Exposure to heavy metals, particularly lead (pb), can lead to aggressive behaviour and the induction of negative perception that may result in jailing. Deficiency of vitamin D can lead to changes and deviations in medical and social terms. The deficiency or insufficiency of vitamin D was substantially associated with depression and addiction. We have also shown that infection with pathogens such as latent toxoplasmosis can lead to changes in perception and involvement in a wide range of violent acts. Currently, the COVID-19 pandemic has provided clear examples of how illness can affect social life. Taken together, we conclude that it is time to speak about molecular sociology as a new branch of sociology to be well framed and thoroughly investigated in the future.
