Cycloaddition of vinyl aziridines with unsaturated substrates. A novel rearrangement of an unsaturated nitro compound.
(Elsevier, 1981)
Vinylaziridine undergoes reaction with electrophilic acetylenes and olefins to produce 7-membered azepine derivatives. With [beta]-nitro-styrene however, a novel rearrangement occurs, presumably via an ene reaction to ...
Energy‐Efficient Oil–Water Separation of Biomimetic Copper Membrane with Multiscale Hierarchical Dendritic Structures
(Wiley Periodicals, Inc., 2017-09)
Probing the temperature sensitivity of induction time in latent cure epoxy resins
(John Wiley & Sons, Ltd, 2013-10)
Two dynamic viscosity datasets for epoxy resins cured at temperatures between 100 and 150 °C were re‐analyzed to compare the interpretation of gel times and activation energies using two mathematical models. © 2012 Society ...
Characterization of nucleic acid higher order structure by gas-phase H/D exchange in a quadrupole-FT-ICR mass spectrometer
(Wiley Subscription Services, Inc., A Wiley Company, 2009-04)
Nucleic acid higher order structure is of intense interest in antisense and antigene strategies toward novel chemotherapeutic agents. Understanding how structural characteristics affect solution-phase properties is essential ...
Revisiting the Response Mechanism of Polymeric Membrane Based Heparin Electrodes
(WILEY‐VCH Verlag, 2012-01)
Potentiometric membrane electrodes that respond to heparin and other polyanions were introduced in the early 1990s. Herein, the mechanism of polymer membrane electrode type heparin sensors is revisited. The extraction/diffusion ...
Thermodynamics of iron sulfides I. Heat capacity and thermodynamic properties of Fe9S10 at temperatures from 5 K to 740 K
(Elsevier, 1991-03)
Measurements of the heat capacity of Fe9S10 over the temperature range 5 K to 740 K reveal a first-order structural transition at 495 K and two higher-order transitions with maxima at 534 K and 591 K. The last two are of ...
Studies on the synthesis and structure of cordycepin monophosphate
(Elsevier, 1963)
Cordycepin monophosphate has been synthesized by two methods. One of these was chemical and involved treatment of cordycepin with cyanoethyl phosphate in the presence of N,N'-dicyclohexylcarbodiimide with subsequent alkaline ...
Phosphoproteins from calf-thymus nuclei: Studies on the method of isolation
(Elsevier, 1969-11-11)
Multiple frequency EPR studies on three forms of oxidized cytochrome c oxidase
(Elsevier, 1983-10-17)
Bovine heart mitochondrial cytochrome c oxidase (cytochrome aa3) (EC 1.9.3.1) has been demonstrated to occur in several forms when the redox centers in the protein are thought to be fully oxidized. We report here the results ...
