Single and multiple random walks on random lattices: Excitation trapping and annihilation simulations
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-02)
Random walk simulations of exciton trapping and annihilation on binary and ternary lattices are presented. Single walker visitation efficiencies for ordered and random binary lattices are compared. Interacting multiple ...
Space-and time-resolved diffusion-limited binary reaction kinetics in capillaries: experimental observation of segregation, anomalous exponents, and depletion zone
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-12)
An experimental investigation of one-dimensional, diffusion-limited A+B→C chemical reactions is reported. The persistence of reactant segregation and the formation of a depletion zone is observed and expressed in terms of ...
Exciton percolation. II: Naphthalene 1B2u supertransfer
(Elsevier, 1977-05)
The exciton percolation theory has been tested for the migration of the lowest singlet exciton in our model organic alloy system at low temperature (2 K): binary isotopic mixed crystals of naphthalene (C10H8--C10D8), with ...
Simultaneous enzymatic/electrochemical determination of glucose and L -glutamine in hybridoma media by flow-injection analysis.
(Wiley Subscription Services, Inc., A Wiley Company, 1993-04-25)
A split-stream flow-injection analysis system is described for simultaneous determination of glucose and L -glutamine in serum-free hybridoma bioprocesses media. Amperometric measurement of glucose is based on anodic ...
Percolation and cluster distribution. II. layers, variable-range interactions, and exciton cluster model
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1978-09)
Monte Carlo simulations for the site percolation problem are presented for lattices up to 64 x 10 6 sites. We investigate for the square lattice the variable-range percolation problem, where distinct trends with bond-length ...
Kinetics of phase changes in large molecular clusters
(Springer-Verlag, 1991-03)
A method has been devised to study the kinetics of phase changes in an unfamiliar regime of extreme undercooling and rate of transformation. We show how electron diffraction can monitor the time evolution of phase changes ...
Spectroscopic and optically detected magnetic resonance studies of PO2- in potassium chloride. II. Magnetic resonance analysis
(Elsevier, 1979-07-15)
The optically detected magnetic resonance (ODMR) spectrum of phosphorus activated potassium chloride crystals obtained at 2 K in zero and weak applied external magnetic fields is reported and analyzed. A theoretical fit ...
Dynamics of energy transport in ternary molecular solids. II. Time evolution of naphthalene fluorescence
(Elsevier, 1983-07-15)
The spectrally resolved time-evolution of free and trapped singlet excitons was obtained at liquid-helium temperature for ternary crystals of perdeuteronaphthalene/naphthalene/betamethylnaphthalene (host/guest/supertrap). ...
