A process to produce fibers from Poly(m-phenyleneisophthalamide)(PMIA) solution in an ionic liquid via wet-spinning technology are described. The spinning process was investigated on a small laboratory scale. Ionic liquid spinning solutions were first prepared for PMIA fibers, followed by wet spinning. In the course of this research, the physical properties of the PMIA fibers were estimated. We...

We investigate the non-adiabatic dynamics of spinning black hole binaries by using an analytical Hamiltonian completed with a radiation-reaction force, containing spin couplings, which matches the known rates of energy and angular momentum losses on quasi-circular orbits. We consider both a straightforward post-Newtonian-expanded Hamiltonian (including spin-dependent terms), and a version of th...

−A new method is introduced to build up organic/organic multilayer films composed of cationic poly(allylamine hydrochloride) (PAH) and negatively charged poly(sodium 4-styrenesulfonate) (PSS) by using the spinning process. The adsorption process is governed by both the viscous force induced by fast solvent elimination and the electrostatic interaction between oppositely charged species. On the ...
