Modeling of immunosensors under nonequilibrium conditions : II. Experimental determination of performance characteristics
(Elsevier, 1991-08-01)
In an attempt to optimize immunosensors operating with an immobilized antibody as binding protein and an analyte-enzyme conjugate as signal generator that is significantly larger in molecular size than the analyte, in a ...
Synthesis of 4-Amino-1-([beta]-D-ribofuranosyl)pyrrolo[2,3-d]pyridazine; an entry into a novel series of adenosine analogs
(Elsevier, 1991)
The synthesis of a novel adenosine analog, 4-amino-1-([beta]-D-ribofuranosyl)pyrrolo[2,3-d]pyridazine, has been accomplished using pyrrole nucleoside precursors.
Preparation and characterization of maleimide-terminated poly(arylene ether sulfone) oligomers of various molecular weights
(Wiley Subscription Services, Inc., A Wiley Company, 1991-11-20)
A new variation in the bismaleimide (BMI) resin family, maleimide-terminated poly(oxy-1,4-phenylene sulfonyl-1,4-phenylene) oligomers, has been synthesized. The preparation of oligomers ( n = 1–12) is described in this ...
Low dimensional reaction kinetics and self-organization
(Elsevier, 1991-02)
Diffusion-limited reaction kinetics becomes anomalous not only for fractals, with their anomalous diffusion, but also for low-dimensional (one and two) and disperse media, where the random walk is compact. We focus on ...
Pathway of formation and catalase activity in a dioxo bridged Mn(IV) dimer.
(Elsevier, 1991-08)
Relativistically parameterized extended HÜckel calculations. 13. Energy bands for uranium compounds UB 2 , UB 4 , UC, UBC, and UPt 3
(John Wiley & Sons, Inc., 1991)
The extension of the relativistically parameterized extended HÜckel method REX to systems with translational symmetry is reviewed. This extension ( REXBAND ) is then applied to the description of the electronic structures ...
The major component of a large, intracellular proteinase accumulated by inhibitors is a complex of [alpha]2-macroglobulin and thrombin
(Elsevier, 1991-05-30)
A large, intracellular proteinase accumulated by inhibitors (PABI) was found in cultured mammalian cells as a large, multicatalytic proteinase with a greatly elevated concentration in the presence of small peptide proteinase ...
Ab initio characterization of several states of nitroxylium (NO 3 + ). Comparison of fragmentation energies of nitroxylium, nitroxyl (NO 3 ), and nitrate
(John Wiley & Sons, Inc., 1991-01)
Ab initio calculations have been performed at the self-consistent field (HF) level, and its perturbative extensions up to fourth-order (MPn), for several electronic states of nitroxylium (NO 3 + ) as well as for a large ...
Optical emission spectroscopy of electron-cyclotron-resonance-heated helium mirror plasmas
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-03)
In this experiment emission spectroscopy in the 3000–5000 Å range has been utilized to determine the electron temperature (15–60 eV) and ion density (2–5 x 10 11 cm −3 ) of helium plasmas produced by the Michigan mirror ...
A quantitative adhesion test for thin polymer films on silicon substrates
(Wiley Subscription Services, Inc., A Wiley Company, 1991-10-05)
The standard 90° peel test was modified in order to apply it to testing adhesion of thin polymer films to surfaces of silicon substrates, such as the silicon nitride passivation layer used in our solid-state chemical ...
