Equilibrium-limited periodic separating reactors
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1987-08)
A new unit operation is presented that utilizes a rapid feed pressure swing cycle in a bed packed with catalyst and adsorbent to effect both reaction and separation. This hybrid device combines features of a cyclic-steady-state ...
Linear viscoelastic materials with environmental dependent properties
(Elsevier, 1971-02)
This study expands on the linear theory of thermo-viscoelasticity to include a larger group of materials and environmental effects. The development rests on the observation that for many materials the creep curve which ...
Vector-like fermion and standard Higgs production at hadron colliders
(Elsevier, 1990-04-09)
Vector-like fermions are characterized by large neutral current decay rates, in particular into Higgs bosons. If they exist, their clear signals at hadron colliders open a window to Higgs detection, especially to the ...
Optimal control problems with maximum functional
(American Institute of Aeronautics and Astronautics, 1991)
Stress - strain isotherms and thermoelastic properties of crosslinked amorphous polyoxyethylene in compression
(Elsevier, 1975-05)
Stress-strain isotherms at a number of temperatures in the range 45-85[deg]C have been determined for a compressed, amorphous polyoxyethylene network swollen with a constant amount of non-volatile diluent. The observed ...
The preparation and some reaction of F2PSPF2 and F2PC(CF3)2OPF2, and the synthesis of the bis-borane adduct of F2PSSPF2
(Elsevier, 1976)
The potentially bidentate fluorophosphine ligand F2PSPF2 can be prepared in 75% yield from the reaction of F2PBr and [(C4H9)3Sn]2S. On the basis of infrared and Raman spectra, the compound has been assigned a bent confirmation ...
Simulation and theory of abnormal grain growth--anisotropic grain boundary energies and mobilities
(Elsevier, 1989-04)
Abnormal grain growth has been studied by means of a computer-based Monte Carlo model. This model has previously been shown to reproduce many of the essential features of normal grain growth. The simulations presented in ...
Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
Application of resonance Raman spectrometry to the determination of vitamin b12
(Elsevier, 1975-05)
