Strain-induced crystallization II. Subsequent fibrillar-to-lamellar transformation Previously presented at the ACS Symposium on Fiber and Yarn Processing Philadelphia (April 9, 1975)
(Society of Plastics Engineers, Inc.Wiley Periodiocals, Inc., 1976-03)
Part II discusses numerous examples of a morphological fibrillar-to-lamellar transformation that has reportedly been observed in stretched polymers upon additional thermal treatment (or TIC), Stretched polymers containing ...
Adsorption of Nitrogen, Oxygen and Argon on Na-CeX Zeolites
(Kluwer Academic Publishers; Springer Science+Business Media, 2002-12)
Commercial type X zeolites (Linde 13X) are nitrogen selective. Oxygen is the less abundant component in air; hence oxygen selective sorbents are desired for air separation. Mixed Na-Ce type X zeolites containing different ...
Dissolution kinetics: Catalysis by strong acids
(Elsevier, 1981-07)
The dissolution of silicate minerals in mixtures of hydrofluoric acid and strong acids such as HCl is catalyzed by H+ ions adsorbed at the mineral surface. Studies of the catalyzed dissolution of kaolinite, quartz, potassium ...
Theoretical basis for the Dubinin-Radushkevitch (D-R) adsorption isotherm equation
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-09)
The Dubinin-Radushkevitch (D-R) equation, which was originally proposed as an empirical adaptation The Polanyi adsorption potential theory, has been the fundamental equation to quantitatively describe the adsorption gases ...

Current concepts of morphology of amorphous polymers-- II. Degree of local order and overall chain conformation
(Elsevier, 1979)
After a brief discussion on our earlier electron microscopyrresults of amorphous polymers and the results obtained by others in recent years from small angle neutron scattering and optical anisotropy measurements, it is ...
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. ...
