Chemistry of alkoxide precursors

Abstract: In view of the increasing applications of metal alkoxides as precursors for ceramics, the physicochemical aspects of successive steps in the S-S-G process are being intensively investigated by sophisticated techniques like NMR (1H as well as multinuclear), SAXS, SANS, XANES, EXAFS and CRAMPS. Besides lower temperatures of sintering, the main advantage of the S-S-G process is the intimacy of mixing at the molecular level, resulting in the homogeneity of the final desired product. The formation of new bonds in mixtures of alkoxides has been confirmed by the isolation of polymetallic alkoxides, in which variations in the coordination environment of the central metal atom offer attractive possibilities for differing networks in ceramics with the same composition. The physicochemical properties of alkoxides have been explained on the basis of inductive and steric effects, degree of association, volatility as well as alcoholysis and hydrolysis reactions. These have been finally correlated with structural elucidation, which is being pursued much more vigorously during the past 1–2 years.

Chapter 3 The Archaean and Proterozoic history of Peninsular India: tectonic framework for Precambrian sedimentary basins in India

Abstract: The Precambrian geological history of Peninsular India covers nearly 3.0 Ga. The Peninsula is an assembly of five different cratonic nuclei known as the Aravalli–Bundelkhand, Eastern Dharwar, Western Dharwar, Bastar and Singhbhum cratons along with the Southern Granulite Province. Final amalgamation of these elements occurred either by the end of the Archaean (2.5 Ga) or by the end of the Palaeoproterozoic ( c. 1.6 Ga). Each of these nuclei contains one or more sedimentary basins (or metasedimentary basins) of Proterozoic age. This chapter provides an overview of each of the cratons and a brief description of the Precambrian sedimentary basins in India that form the focus of the remainder of this book. In our view, it appears that basin formation and subsequent closure can be grossly constrained to three separate intervals that also broadly correspond to the assembly and disaggregation of the supercontinents Columbia, Rodinia and Gondwana. The oldest Purana-I basins developed during the 2.5–1.6 Ga interval, Purana-II basins formed during the 1.6–1.0 Ga interval and the Purana-III basins formed during the Neoproterozoic–Cambrian interval.

A new analysis of fractional fish farm model associated with Mittag-Leffler-type kernel

Abstract: In this paper, we analyze the dynamical behavior of fish farm model related to Atangana–Baleanu derivative of arbitrary order. The model is constituted with the group of nonlinear differential equa...

Measurement Of Charge Multiplicity Asymmetry Correlations In High-energy Nucleus-nucleus Collisions At Snn =200 Gev

Abstract: A study is reported of the same-and opposite-sign charge-dependent azimuthal correlations with respect to the event plane in Au+ Au collisions at root(S)(NN) = 200 GeV. The charge multiplicity asymmetries between the up/down and left/right hemispheres relative to the event plane are utilized. The contributions from statistical fluctuations and detector effects were subtracted from the (co-) variance of the observed charge multiplicity asymmetries. In the mid-to most-central collisions, the same- (opposite-) sign pairs are preferentially emitted in back-to-back (aligned on the same-side) directions. The charge separation across the event plane, measured by the difference, Delta, between the like-and unlike-sign up/down-left/right correlations, is largest near the event plane. The difference is found to be proportional to the event-by-event final-state particle ellipticity (via the observed second order harmonic nu(obs)(2)), where Delta = [ 1.3 +/- 1.4( stat)(-1.0)(+4.0)(syst)] x 10(-5) + [3.2 +/- 0.2(stat)(- 0.3)(+0.4)(syst)] x 10(-3)v(2)(obs) for 20- 40% Au + Au collisions. The implications for the proposed chiral magnetic effect are discussed.
