Substrate Interactions during the Biodegradation of Benzene, Toluene, Ethylbenze, and Xylene (BTEX) Hydrocarbons by the Fungus Cladophialophora sp. Strain T1

, 2002
The soil fungus Cladophialophora sp. strain T1 (= ATCC MYA-2335) was capable of growth on a model water-soluble fraction of gasoline that contained all six BTEX components (benzene, toluene, ethylbenzene, and the xylene isomers).

Enantioselective Synthesis of a New Class of Stable and Functionalized Cyclopentadienes via CuH‐Catalysis

Angewandte Chemie, EarlyView.
Cyclopentadienes (CpHs) are fundamental building blocks with widespread applications in chemistry. However, their inherent acidity and isomeric instability have long limited access to chiral variants in an asymmetric fashion. Here, we introduce a CuH‐catalyzed asymmetric transformation that provides an unprecedented entry into a new class of ...

Fluorinated hydrocarbons as MRI contrast agents

Proceedings of the 15th Annual International Conference of the IEEE Engineering in Medicine and Biology Societ, 2005
MRI contrast agents have been widely used to enhance tumor detection and improve tumor image quality. Particulate MRI contrast agents using conventional proton magnetic resonance imaging have met with limited success. Herein, we report a process to microencapsulate fluorinated hydrocarbons in a biocompatible protein shell and their efficacy as ...
