Title: Self-regulating chemo-mechano-chemical systems

Abstract

A chemo-mechano-chemical (C.sub.1-M-C.sub.2) system includes a base supporting an actuatable structure, said structure comprising a functionalized portion and being embedded in an environmentally responsive gel capable of volume change in response to an environmental stimulus; a first fluid layer disposed over the base and in contact with the actuatable structure, said first fluid layer comprising the environmentally responsive gel; and a second fluid layer in contact with the actuatable structure, wherein the layers are positioned such that the functionalized portion is in contact with the second layer in a first relaxed state and in contact with the first layer in a second actuated state and wherein the functionalized portion interacts with at least one of the layers to provide a chemical or physical response.

  • A magnet levitation self-regulating system is described comprising monotypic magnetic devices combined together by rigid nonmagnetic couplers; said magnetic device comprising two cylindrical parts extended along a cylinder generatrix: a. an iron core having a symmetrical C-shaped cross section and an air gap between its core shoes; and b. a permanent magnet having a rectangular cross-section disposed in said air gap; wherein all the iron cores of said magnetic devices are fixed on a common foundation by a first plurality of rigid nonmagnetic couplers and formed a stator assembly; all the permanent magnets of said magnetic devices are connected togethermore » by a second plurality of rigid non-magnetic couplers and form a levitator assembly; said permanent magnets of said levitator generate an original magnetic field and magnetize the stator cores; said stator cores create a secondary magnetic field; both said original and secondary magnetic fields create a magnetic levitation force that provides a stable hovering of said levitator in a resulting magnetic field of said system.« less
  • The central theme of this project is that the reaction, transport and mechanical processes affect each other so strongly that basin diagenesis takes on a qualitatively different behavior than what would be predicted by the analysis of the individual processes separately.
  • The central theme of this project is that the reaction, transport and mechanical (RTM) processes affect each other so strongly that basin diagenesis takes on a qualitatively different behavior than what would be predicted by the analysis of the individual processes separately. In Figs. 1 and 2 we see schematic basin cross-sections that emphasize a few of the diagenetic phenomena arising from the strong coupling of RTM processes. Basin diagenesis allows for a great richness of phenomena (Fig. 1) including the genesis of a (formation localized) basal seal, dynamic transbasinal top seal, fault related side seals, episodic fluid release andmore » smaller scale compartmentation within and adjacent to the basin-scale overpressured compartment and also (Fig. 2) fingered reaction fronts and upwardly migrating petroleum and auto-localized petroleum (through petroleum-induced porosity preservation). The phenomena of Figs. 1 and 2 arise through feedback loops in the RTM process network.« less
