Boron-modified polysilylcarbodi-imides as precursors for Si–B–C–N ceramics: Synthesis, plastic-forming and high-temperature behavior
(John Wiley & Sons, Ltd., 1998-10)
The synthesis, by two different reaction pathways, of boron-modified polysilylcarbodi-imides of general type {B[C 2 H 4 Si(R)NCN] 3 } n (R 14=singly bonded organic ligand) and the plastic-forming and the thermal behavior ...
Topological studies of spinach 22 kDa protein of Photosystem II
(Elsevier, 1994-12-30)
An intrinsic 22 kDa polypeptide is associated with the O2-evolving Photosystem II core complex in a variety of green plants, although it does not appear to be required for O2 evolution. Digestion of thylakoid membranes and ...
The sampling properties of some distance geometry algorithms applied to unconstrained polypeptide chains: A study of 1830 independently computed conformations
(Wiley Subscription Services, Inc., A Wiley Company, 1990-10)
In this paper we study the statistical geometry of ensembles of poly(L-alanine) conformations computed by several different distance geometry algorithms. Since basic theory only permits us to predict the statistical ...
Studies on the kinetics and mechanism of reduction of flavodoxin from Peptostreptococcus elsdenii by sodium dithionite
(Elsevier, 1973-07-05)
1. 1. The reactions of the oxidised and semiquinone forms of Peptostreptococcus elsdenii flavodoxin with sodium dithionite have been studied by stopped flow spectrophotometry. At low ionic strength where comproportionation ...

Role of conformational dynamics in sequence-specific autoantibody•ssDNA recognition
(Wiley Subscription Services, Inc., A Wiley Company, 2007-04-05)
11F8 is a sequence-specific monoclonal anti-ssDNA autoantibody isolated from a lupus prone mouse that forms pathogenic complexes with ssDNA, resulting in kidney damage. Prior studies show that specificity is mediated by a ...
Entropy and heat capacity of europium(III) bromide from 5 to 340 K
(Elsevier, 1975-07)
The heat capacity of a polycrystalline sample of EuBr3 has been measured from 5 to 340 K and found to be without transitions in this region. Values of the thermodynamic functions Cp(T), {So(T) - So(5 K)}, and {Ho(T) - Ho(5 ...
Progress in Practice: Exploring the Cooperative and Collaborative Dimensions of Group Learning
(Springer-Verlag; Springer-Verlag New York, Inc., 1996-03)
We all participate in a variety of groups as part of our daily lives, from families to social and work communities. As chemists, we are part of our college departments, our professional societies, our research groups, and ...
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 ...
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 ...
