Two-dimensional zeolites: current status and perspectives.

A plurality of co-operative and complementary software programs are implemented in a web-enabled high speed computer system to remotely monitor, manage and modify the operational and functional parameters of a plurality of implanted medical devices (IMDs). The system utilizes virtual electrophysiologist module (VEM), chronic monitoring module (CMM) and prescription program module (PPM) programs to effect specific therapeutic and diagnostic methods for managing the IMDs, remotely on a conditions and real-time basis. The modules enable remote and continuous monitoring, management and maintenance of the IMDs by identifying critical medical events, determining optimal clinical settings and upgrading performance parameters based on prescriptive data. The modules are implemented in a data center having high-speed computers operating in a web-enabled environment. The modules and the IMDs communicate through wireless communications system via a programmer or an interface medical unit (IMD).

Zeolite ZSM-57 and catalysis therewith

Light olefins are converted to heavier hydrocarbon products, e.g., those boiling in the gasoline, distillate and/or lube range, over zeolite MCM-22 catalyst.

Process for converting olefins to higher hydrocarbons

A catalytic process is provided for converting C 2 to C 12 aliphatic hydrocarbons to aromatics by contacting them under conversion conditions with a crystalline zeolite catalyst having a Constraint Index of about 1 to 12 and containing gallium. Preferably, the zeolite is a low acidity zeolite. In certain embodiments, gallium is inserted into the zeolite framework. Gallium can also be deposited, exchanged or impregnated into the zeolite.
