TL;DR: In this paper, the effects of wide-range γ irradiation on polyurethane samples were examined through a series of analytical techniques, including scanning electron microscopy and dynamic mechanical thermal analysis.

TL;DR: A simple method to control the conductive network formation is presented, which can help to design PNCs with high electrical conductivity, and especially anisotropy.

TL;DR: In this article, the phase inversion of polyolefin elastomer (POE)/polypropylene (PP) blend was studied simultaneously by density functional theory and experiments, and the predicted nanoparticle size of POE nuclei is in general agreement with their experimental measurement.

TL;DR: In this article, a preparation method of a eucommia ulmoides gum elastomer, belonging to the field of elastic materials, was revealed, and the method comprises the following concrete steps of preparing the euCommia ulmides gum into a solution with certain concentration, and performing hydrogenation reaction at the temperature of 80-140 DEG C under the pressure of 20-50 bar for 1-8 hours, wherein the usage amount of a noble metal catalyst is 0.5-5%.

TL;DR: In this article, it was shown that if a bounded solution of a parabolic equation decays fast at a time, then the solution must vanish identically before that time, provided the coefficients of the equation satisfy appropriate conditions at infinity.
