The influence of sugar-phosphate backbone on the stacking interaction in the adenine…thymine base-pair dimer (A…T)2 has been studied using the density functional theoretic method and the dispersion-corrected density functional BLYP-D3 and the triple-zeta quality basis set def2-TZVP. In the absence of the sugar-phosphate backbone, several stacked conform-ers were obtained with a small difference in their stabilization energy values (-20 to -25 kcal/mol). However, the presence of the sugar-phosphate back-bone limits the movement of the two A…T units, and yet the stacking interaction remains significant (-19.4 kcal/mol). Despite the constraints imposed by the backbone, the dimer (A…T)2 is found to retain its favourable geometry. The influence of sodium ions on the geometry and the interaction energy is found to be negligible.Keywords

It is shown by ab initio calculations using secondorder Møller-Plesset perturbation theory and 6-31g, aug-cc-pVDZ and aug-cc-pVTZ basis sets and coupled cluster singles, doubles and perturbative triples method with the 6-31g basis set, that it is possible to stabilize the cage structure of the smallest fullerene C20 by encapsulating small cations like H+ and He2+. While the latter stabilizes the cage structure by charge transfer, the former prefers to form a covalent linkage with the carbon atoms.Keywords

It is difficult to believe that Charusita Chakravarty is no more. Born in Cambridge, Massachusetts, USA on 5 May 1964 as the only daughter of the economists Sukhamoy and Lalita Chakravarty, Charu grew up in a liberal academic environment in Delhi. She chose to give up her American citizenship and become Indian when she was in her twenties.Full Text

One of the things that we learn in our early childhood is numbers: 1, 2, 3,… in our mother tongue. Subsequently, we learn the difference between zero and nonzero, about smaller and larger numbers, and about integers and non-integers. Much later we learn about negative numbers, and rational and irrational numbers. As Indians, we are proud of our Bhaskaracharya of ancient times and Srinivasa Ramanujan of recent times. Kanigel declared the latter to be the man who knew infinity.Full Text

Now that the Government of India has decided to set up the Higher Education Commission of India (HECI), it is time to look at the challenges ahead.
The University Grants Commission (UGC) will cease to exist. All India Council of Technical Education (AICTE) and the National Council for Teacher Education (NCTE) will continue to function. National Assessment and Accreditation Council (NAAC) will continue too.

I was excited when I was asked to review this volume of the Annual Review of Physical Chemistry (ARPC) because I could read the articles by active practitioners on current topics in physical chemistry. With the growing literature, one could no longer pretend to be up on things even in one’s own domain of science. ARPC gives you the pulse of physical chemistry as it is practised, covering a wide spectrum (pun intended), from molecules to materials, living as well as non-living. The approach could be ab-initio or phenomenological, bottomup or top-down.Full Text
