An Investigation of Online and Face-to-Face Communication in General Chemistry

Autor: Gabriela Weaver, Kellie Green, Aliya Rahman, Erik Epp

Publikováno v: International Journal for the Scholarship of Teaching and Learning, Vol 3, Iss 1 (2009)

This exploratory study investigated an online office hour and a face-to-face recitation for similarities and differences. The online office hour and face-to-face recitation were a part of general chemistry courses taught at different universities. Th

Although H is nonpolar in the equilateral triangle equilibrium structure, symmetry breakdown due to centrifugal distortion causes a small dipole moment and hence rotational transitions. The spontaneous emission times are on the order of a few weeks f

Chemoenzymatic enantioselective synthesis of phenylglycine and phenylglycine amide by direct coupling of the Strecker synthesis with a nitrilase reaction

Autor: Erik Eppinger, Janosch Alexander David Gröning, Andreas Stolz

Publikováno v: Frontiers in Catalysis, Vol 2 (2022)

The conversion of rac-phenylglycinonitrile by different variants of the nitrilase from Pseudomonas fluorescens EBC191 (EC 3.5.5.1) was studied and the amounts and chiral composition of the formed phenylglycine and phenylglycine amide compared. Mutein

Comparative Analysis of the Conversion of Mandelonitrile and 2-Phenylpropionitrile by a Large Set of Variants Generated from a Nitrilase Originating from Pseudomonas fluorescens EBC191

Autor: Andreas Stolz, Erik Eppinger, Olga Sosedov, Christoph Kiziak

Publikováno v: Molecules, Vol 24, Iss 23, p 4232 (2019)

The arylacetonitrilase from the bacterium Pseudomonas fluorescens EBC191 has been intensively studied as a model to understand the molecular basis for the substrate-, reaction-, and enantioselectivity of nitrilases. The nitrilase converts various aro

Ge-stell and the Specters of the Spectrum

Autor: Erik Eppel

Publikováno v: Forum, Iss 07 (2008)

No more than a few hundred meters separate the site where Gugliemo Marconi first witnessed the extraordinary effects of Hertzian waves in 1895, and the site where armored vehicles crashed through barricades in order to put down a riot allegedly incit
