1. On the Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on Bis-triazine-bipyridine (BTBP) ligands
Abstract : Used nuclear fuel is dangerous for mankind and her environment for a long time. If however, the minor actinides together with uranium and plutonium could be transmuted, i.e. transformed, into more shortlived or stable isotopes the volume of the waste could be significantly reduced together with a reduction in the radiotoxicity.

2. Computational Analysis of Molecular Recognition Involving the Ribosome and a Voltage Gated K+ Channel
Abstract : Over the last few decades, computer simulation techniques have been established as an essential tool for understanding biochemical processes. This thesis deals mainly with the application of free energy calculations to ribosomal complexes and a cardiac ion channel. READ MORE

3. Multiple Functions of Glutathione Transferases : A Study on Enzymatic Function, Regulatory Role and Distribution in Mouse and Man
Abstract : To cope with various endogenous toxin and xenobiotics nature has equipped the organisms with a proper protection system. Glutathione transferases (GSTs) are important components of the cellular defense against oxidative stress. These proteins appear to be suited for different tasks. READ MORE

4. Development and application of new chiral -amino alcohols in synthesis and catalysis : Use of 2-azanorboryl-3-methanols as common intermediates in synthesis and catalysis
Abstract : The development and application of unnatural amino alcohols,prepared via hetero-Diels-Alder reactions,in synthesis and catalysis is described.The studies are concerned with the [i]scope of the hetero-Diels-Alder reaction and preparation of important intermediates in the synthesis of antiviral agents,[ii ]application of amino alcohols in the ruthenium transfer hydrogenation of ketones,[iii ]use of similar precursors in the in situ generation of oxazaborolidines for reduction of ketones,and [iv] development and application of new chiral auxiliaries for dialkylzinc additions to activated imines, respectively.

5. Energy and Electron Transfer in Porphyrin-Based Donor--Bridge--Acceptor Systems
Abstract : The photophysical properties of supramolecular donor--bridge--acceptor systems have been investigated by spectroscopic and quantum mechanical methods. The systems consist of porphyrin donor and acceptor moieties linked by bridging chromophores of varying excitation energy, and are shown to be geometrically well-defined in terms of length and rotational conformation.
