Cover Picture Nanohybrids Composed of Quantum Dots and Cytochrome P450 as Photocatalysts (Angew. Chem. Int. Ed. 32006)код для вставкиСкачать
Cover Picture Binil Itty Ipe and Christof M. Niemeyer* Sunlight does chemistry in nanohybrids composed of CdS quantum dots (QDs) and enzyme P450BSb. The hybrids, which are self-assembled through electrostatic interactions between the negatively charged QDs and the positively charged His6marked P450, produce hydroxyl and superoxide radicals upon irradiation. In their Communication on page 504 ff., B. I. Ipe and C. M. Niemeyer report that these reactive oxygen species activate P450 to catalyze the monooxygenation of myristic acid. (Graphic prepared by P. Alhorn, B. Ipe, and K. Rabe.) Tandem Transformations In their Minireview on page 354 ff., J.-A. Ma and H.-C. Guo discuss the latest developments in catalytic asymmetric tandem transformations initiated by conjugate additions to construct complex molecules with several stereogenic centers. Superheavy Elements The heaviest artificially generated elements lie in the area of the transactinides. Experimental and theoretical work aimed at understanding these superheavy elements is reported by M. Sch6del in his Review on page 368 ff. Electrocatalysis The properties of a water/Pd(111) interface change as a function of the applied potential. In their Communication on page 402 ff., M. Neurock and J.-S. Filhol analyze this problem through ab initio methods.
