Abstract:
... Silicon-containing arylacetylene resins with rigid conjugated structures in the main chain often exhibit poor processability. A strategy of improving the processability by destroying the molecular structure symmetry using side aromatic groups was proposed, and the effects of the side groups was further explored. Two novel structural resins with side aromatic phenyl and phenylacetylene groups (PODS ...

Abstract:
... Although the individual one- and two-dimensional (1D and 2D) carbon nanostructures possess extremely high thermal conductivity, their macroscopic assemblies do not efficiently utilize it due to the larger interfacial contact thermal resistance. To improve the overall performance, the key is the interfacial structure design to provide sufficient pathways for phonon transport with a limited sacrific ...

Abstract:
... Poly(lactic acid) (PLA) could be a promising replacement for nondegradable polymers, only if it is toughened. However, the current technique of toughening PLA generally requires additional components or post-treatment, and the conflicts among toughness, strength, and transparency are still to be overcome. Herein, by employing a novel compressing–releasing (CCR) process, we fabricated supertough, u ...

Abstract:

We experimentally show that the thermal conductance across confined solid-solution crystalline thin films between parent materials does not necessarily lead to an increase in thermal resistances across the thin-film geometries with increasing film thicknesses, which is counterintuitive to the notion that adding a material serves to increase the total thermal resistance. Confined thin epitaxial Ca₀ ...
