Very High Third-Order Nonlinear Optical Activities of Intrazeolite PbS Quantum Dots

Hyun Sung Kim、Myoung Hee Lee、Nak Cheon Jeong 等 6 位作者2006-11-01Journal of the American Chemical Society

Zeolite-intercalated semiconductor quantum dots (QDs) have long been proposed to give very high third-order nonlinear optical (3NLO) responses. However, measurements of their 3NLO responses have not been possible due to the lack of methods to prepare optically transparent QD-incorporating zeolite films supported on op…

Effect of particle size on the structure and magnetic properties of La0.6Pb0.4MnO3 nanoparticles

T. Zhang、G. Li、Tian Qian 等 6 位作者2006-11-01Journal of Applied Physics

We studied the effect of particle size on the structure and magnetic properties of La0.6Pb0.4MnO3 compounds with particle diameters varying from 5to100nm. With decreasing particle size, the increase of the rhombohedral distortion narrows the bandwidth WO2p and hence results in the decrease of ferromagnetic transition…

Simultaneous Determination of Protein Backbone Structure and Dynamics from Residual Dipolar Couplings

Guillaume Bouvignies、Phineus R. L. Markwick、Rafael Brüschweiler 等 4 位作者2006-11-01Journal of the American Chemical Society

Determination of protein structure classically results in a single average configuration that takes no account of conformational fluctuation. Dynamics are, however, inherently linked to structure and crucial to our understanding of biological function. In this study we have used analytical descriptions of dynamic aver…
