The Press council

This study analyses the role of the Press Council as a champion and guard of free speech. It discusses the extent to which the Council succeeded in achieving its statutory objective of preserving the freedom of the press and maintaining and improving the standards of newspapers and news agencies. It also examines the inherent and in-built weaknesses of the Council and suggests ways and means for restructuring and enlarging its functions.

Blue, Green and Orange-Red Light Emitting Polymers: Synthesis, Characterization and Prospects of Applications in Optoelectronic Devices

Light emitting polymers (LEPs) are considered as the second generation of conducting polymers. A Prototype LEP device based on electroluminescence emission of poly(p-phenylenevinylene) (PPV) was first assembled in 1990. LEPs have progressed tremendously over the past 20 years. The development of new LEP derivatives are important because polymer light emitting diodes (PLEDs) can be used for the manufacture of next-generation displays and other optoelectronic applications such as lasers, photovoltaic cells and sensors. Under this circumstance, it is important to understand thermal, structural, morphological, electrochemical and photophysical characteristics of luminescent polymers. In this thesis the author synthesizes a series of light emitting polymers that can emit three primary colors (RGB) with high efficiency

“Right to Privacy and Freedom of Press - Conflicts and Challenges”

India is a signatory to the United Nations Declaration of Human Rights 1948 and the International Covenant on Civil and Political 1966, the two major International instruments, building the foundations of the major democracies and the constitutions of the world. Both these instruments give an independent and upper position to right to privacy compared to right to freedom of speech and expression. The freedom of press finds its place under this right to freedom of speech and expression. Both these rights are the two opposite faces of the same coin. Therefore, without the right of privacy finding an equal place in Indian law compared to right to freedom of speech and expression, the working of democracy would be severely handicapped and violations against citizens rights will be on the rise It was this problem in law and need to bring a balance between these two conflicting rights that induced me to undertake this venture. This heavy burden to bring in a mechanism to balance these two rights culminated in me to undertake this thesis titled “Right to Privacy and Freedom of Press – Conflicts and Challenges

Lignin recovery, Biochar Production and Decolourisation of Coir pith Black Liquor

Coir pith black liquor obtained as a dark brown filtrate from oxidative delignification needs to be decolourised before releasing to open environment. From this liquor industrially valuable lignin was recovered using acid precipitation method. ‘Biochar’ was produced by slow pyrolysis of coir pith at 500oC and 600oC. Water holding capacity and pH of the biochar were estimated. CHNS analysis was carried out to identify the nutrient profile. Structural characterization was done using FTIR and SEM Studies. Biochar produced at 600oC was found to be more suitable for decolourisation of the coir pith black liquor. FTIR analysis indicated peak changes while SEM analysis indicated surface area and porosity changes. Biochar decolourisation experiments were carried out on crude coir pith black liquor and also on lignin recovered coir pith black liquor.
