Nitric acid etching studies of compositional heterogeneity in mixed-crystal polyethylene single crystals
(John Wiley & Sons, Inc., 1983-11)
No Abstract.
Characterization of a hybrid flame/arc excitation source using monodisperse aerosol introduction
(Elsevier, 1983)
A hybrid flame/arc excitation source together with a monodisperse droplet generator is used to inject solute particles into selected regions of the arc plasma. With astigmatic image transfer and a 0.5 [mu]s time constant ...
Thermodynamics, handmaiden to science and technology
(Kluwer Academic Publishers; Akadémiai Kiadó ; Springer Science+Business Media, 1983-05)
Generally, the only items of reference data with real economic impact are—except in a few instances—the basic values from which the standard enthalpy increment of reactions and the Gibbs energy of formation of the substances ...
One possible explanation for the α* relation in non-crystalline materials
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1983-10)
Synthesis of cyclic and polymeric derivatives of 1,2-dithiol-o-carborane
(Elsevier, 1983-01-18)
Cyclic compounds containing two symmetrically placed 1,2-dicarbaclosododecaboranyl or two 7,8-dicarbaundecaborate(10) moieties have been synthesized. The bridges between the carborane cages are S---S or S---CH2---CH2---S ...
Mixing of phases in non-crystalline materials: Application to carbon
(Elsevier, 1983-09-01)
The atomic structure of non-crystalline solids is described by the correlation function. When more than one phase is present, the simple addition of the correlation functions for the various phases in proportion to their ...
The stability of SiO-based ceramics containing ZRO2 and other oxides
(Elsevier, 1983)
Calculations of thermochemical equilibria, using the program SOLGASMIX, have defined the conditions and compositions of SiO-based ceramics in which stable ZrO2 particles can be obtained. The results are compared with ...
Pyrrolopyrimidine nucleosides 19. A total synthesis of the nucleoside antibiotic cadeguomycin [2-amino-7-([beta]-d-ribofuranosyl)-pyrrolo[2,3-]pyrimidin-4-one-5-carboxylic acid]
(Elsevier, 1983)
A total synthesis of 2-amino-7-([beta]-D-ribofuranosyl)pyrrolo[2,3-]pyrimidin-4-one-5-carboxylic acid has been accomplished and confirms the previous structural assignment for the nucleoside antibiotic cadeguomycin.
A further investigation of the stannic chloride-catalyzed condensation reaction of 1-hexene and 1,2,3,5-tetra-O-acyl-[beta]--ribofuranoses
(Elsevier, 1983-04-16)
The reaction of 1-hexene with either 1-O-acetyl-2,3,5-tri-O-benzoyl-[beta]--ribofuranose (5b) or 1,2,3,5-tetra-O-acetyl-[beta]--ribofuranose (5a) in the presence of stannic chloride leads to the formation of a complex ...
Effects of shearing conditions on crystalline orientation and relaxation in polyethylene
(Society of Plastics Engineers, Inc.Wiley Periodiocals, Inc., 1983-02)
The effects of shearing conditions (i.e., shear temperature and shear rate) on the degree of orientation of polyethylene (Marlex 6006) and to what extent the induced orientation could be relaxed were examined in this study. ...
