Hybrid Composite for Orthopedic Applications surface free energy values, obtained from melting temperature dependence on lamellar thickness, also are found to decrease similarly and agree approximately with the kinetic surface free energy values.disrupt 发表于 2025-3-31 09:31:57
Xing Yan Tan,Hao Wang,Tae Gyu Kimrder of the repeating structure so that a second order Bragg diffraction was observed. When this occurred, the original ℓ. became obscured. In some materials (nylon-11) the changes in long period may have occurred by a different mechanism. The observance of abrupt changes in the long period by an am他日关税重重 发表于 2025-3-31 16:14:59

A. J. Russell,C. P. Bowers,A. J. Mossn linear polyethylene relaxations which are barely detected or undetected in specimens which have been slowly cooled. The acceptance of the 3 relaxation as a secondary relaxation of linear polyethylene is of considerable conceptual significance since it eliminates a long standing paradox presented bMicrogram 发表于 2025-4-1 01:24:53
Jean-Jacques Barrau,Serge Laroze,Daniel Gay.. The experimental data indicate that the dependence of zero shear viscosity on (S.). is substantially greater for LDPE than for linear polymers. The apparent flow activation energy at zero shear is found to be about 12 kcal/mole for all whole LDPE samples of differing LCB characteristics studied i
