Vardeny, Zeev Valentine | Evolution of excitons and polarons in polythiophene from femtoseconds to milliseconds | We have studied the photoexcitation dynamics in electrochemically polymerized polythiophene thin films using transient photomodulation spectroscopy measured from 100 fs to 20 ms in the spectral range from 0.25 to 2.2 eV, and by the novel technique of absorption-detected magnetic resonance (ADMR). ... | Femtoseconds; Milliseconds; Photoexcitation dynamics | 1992-07 |

Thomas, Kirk R.; Capecchi, Mario R. | High-fidelity gene targeting in embryonic stem cells by using sequence replacement vectors. | Mutations were targeted to the Hprt locus in murine embryonic stem cells by using sequence replacement vectors. When the vector was designed such that the mutated sequences were flanked on both sides by several kilobases of DNA homologous to the target locus, replacement of chromosomal sequences wit... | Drug Resistance; Gene Rearrangement; Gentamicins | 1992-07 |
