Role of Infrared Spectroscopy in Coal Analysis—An Investigation  [PDF]
Manoj Balachandran
American Journal of Analytical Chemistry (AJAC) , 2014, DOI: 10.4236/ajac.2014.56044
Abstract: Fourier transform infrared (FT-IR) spectroscopy is a widely used analytical technique for determining the different functional groups of a coal structure. This method, being able to reveal carbo-hydrogenated structures (aromatic and aliphatic) and heteroatomic functions (mainly oxygenated), as well as to detect the presence of minerals, is currently one of the most powerful techniques for coal characterization and thus is of paramount importance in the various utilization procedures of coal (industrial combustion, coke production processes, etc.). FT-IR study shows the presence of aliphatic -CH, -CH2 and -CH3 groups, aliphatic C-O-C stretching associated with -OH and -NH stretching vibrations and HCC rocking. It is conjectured that, the two-stage leaching using HNO3 followed by HF remarkably reduced the ash content as well as the minerals including Al, Si and Ca. The solubilization of samples with buffered EDTA could not eliminate the minerals in coal. The silicate and kaolinite bands showed a systematic lowering on EDTA and carboxylic acid treatment. The fungal leaching was most beneficial for aromatic molecules with different degrees of substitution. The intensity of bands due to carbonyl groups was increased, when treated with fungi, whereas that due to oxygen functional groups showed a reverse trend. The mineral bands due to silicates also decreased in intensity, on post treatment with fungal culture.
Changing Wisdom of Metallic Alloys Development  [PDF]
Manoj Gupta
Materials Sciences and Applications (MSA) , 2018, DOI: 10.4236/msa.2018.913074
Abstract: Metallic alloys have been instrumental through the ages in shaping the progress of human civilization. The development of the alloys from ancient to present time initiated from accidents to through the use of well-defined scientific principles. This article provides a snapshot of the alloys development from ancient to present time and the likely future direction.
Electroplating: Applications in the Semiconductor Industry  [PDF]
Jivaan Kishore Jhothiraman, Rajesh Balachandran
Advances in Chemical Engineering and Science (ACES) , 2019, DOI: 10.4236/aces.2019.92018
Abstract: There is a lot of research that has been done on electroplating of metals depending on the type of application. In this chapter, the importance of this technique to the semiconductor industry is discussed in detail from an experimental as well as a modeling standpoint. In particular, the effect of solution variables i.e. chloride, accelerator, suppressor on copper electrodeposition is discussed. This knowledge is applied to achieve a defect-free, bottom-up metal/copper fill that eventually, is one of the most critical processes in this billion-dollar industry.
Cultures of Protest in Transnational Contexts: Indian Seamen Abroad, 1885-1945
Gopalan Balachandran
Transforming Cultures , 2008,
Abstract: This paper offers a preliminary exploration of contexts and forms of protest and defiance of authority by Indian seafarers employed on ocean-going steam vessels over six decades to the end of World War II. Though relatively small in numbers and apparently untypical in many respects of a ‘modern’ industrial workforce, the study of Indian seafarers can shed interesting light on several wider aspects of Indian labour history. The transnational and trans-cultural context of employment of Indian seamen also helps illuminate their subjectivities, knowledges, and agencies in ways that are obscured in more insular histories, while their encounters with bosses and others in authority invite us to re-examine pervasive notions of cultural difference–‘owned’ as well as attributed. This paper is not about union-led protests, nor about ‘everyday’ forms of resistance. It dwells instead on a potentially vast and apparently uncharted middle ground of collective resistance by ships’ crews. Such resistance, perhaps simmering for weeks at sea, came to head at key moments, usually upon arrival at a foreign port, close to sailing, or when seamen were being transferred from one vessel to another. It could involve, besides the seamen themselves and their ships’ officers, a swathe of state agencies including local authorities, the police, and the judiciary, though rarely if ever, unions of local seamen. On the evidence here, the culture of work and protest of Indian seamen appears to have been informed by a certain rationality–a certain careful weighing of costs, benefits, and opportunities for engagement and disengagement, including through protest–that is altogether at odds with characteristic representations of Calcutta jute workers and British maritime workers enduring similar circumstances or facing similar ‘choices’. At the same time this culture was open to modern, secular, and transnational solidarities grounded in universalist values. Paradoxes of this nature demand a sustained effort to recover and re-interpret the complex but immensely creative subjectivities that Indian workers and seafarers (and needless to add other Asian, African, and Caribbean workers and seamen) developed and articulated within the fluid and liminal spaces they inhabited.
