The results of our study reveal non-thermal phase transition at both relativistic and ultrarelativistic energy. <br/> <br/>Page(s): 839-843 Sat, 28 Nov 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/6611 Title: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place" downloadurl="http://www.5iantlavalamp.com/"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="City" downloadurl="http://www.5iamas-microsoft-com:office:smarttags"> Crystal and molecular structure of 2-thiobenzylazobenzene (C₁₉H₁₆N₂S) </smarttagtype></smarttagtype> <br/> <br/>Authors: Karmakar, Sanjib; Patowary, K; Bhattacharjee, S K; Deka, B; Chakraborty, A <br/> <br/>Abstract: The title compound (I, W=X=Y=H, Z = CH2Ph) is a divalent organosulphur compound of the type Ar-S-Z belonging to the class of ortho mercaptoazo compounds. The azo group is moved away from the sulphenyl sulphur atom to attain the stable <i>trans</i> azo configuration. The sulphur atom has used hybrid orbitals (sp3) and not pure <i>p</i>-orbitals for the bond formation. The benzyl units attached to the sulphenyl sulphur and the 2-benylazo unit are moved away from each other for steric reason. The molecule is as a whole non-planar but N1 and N2 atoms are coplanar with the respective phenyl rings to which they are attached. The S1 atom is coplanar with the phenyl group to which it is attached. The dihedral angle between the mean planes passing through the atoms of the thiophenyl group and the benzyl group is 75(1)°. There is no intermolecular hydrogen bond and the molecule is stabilised by the network of Van der Waal's interaction in their crystalline assembly. <br/> <br/>Page(s): 863-866 Sat, 28 Nov 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/6610 Title: Alpha spectra and Yukawa potential as static part of the barrier <br/> <br/>Authors: Agrawal, S K <br/> <br/>Abstract: Yukawa potential has been applied as static part in the non - local <img src='/image/spc_char/alpha.gif'> -nucleus potential to calculate the relative intensities of the <img src='/image/spc_char/alpha.gif'> -spectra of some rare earth and heavy nuclei. The results are found to be in good agreement with the observed values. <br/> <br/>Page(s): 889-891 Sat, 28 Nov 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/6609 Title: Study of tetracene thin film transistors using La₂O₃ as gate insulator <br/> <br/>Authors: Sarma, R; Saikia, D <br/> <br/>Abstract: Tetracene organic field-effect transistors (OFET) have been fabricated and investigated with La₂O₃ as gate insulator. The fabricated organic thin film transistors exhibit <i>p</i>-type conductivity with field effect mobility 1.04×10^-4 cm²/V.s, ON-OFF ratio 3.465, sub-threshold swing 17.8 mV/decade and hole concentration 1.25×10¹⁹ cm^-3. The SEM and XRD analysis on the semiconductor film were have also been reported. <br/> <br/>Page(s): 876-879 Sat, 28 Nov 2009 22:58:59 GMT
