Synergistic contagions are common in natural and social systems, with network topology playing a crucial role in shaping these dynamics. Despite extensive researches, a comprehensive understanding of how specific structural features influence synergistic contagions, especially their phase transitions, remains lacking. This study demonstrates that the spectral approach can serve as a high-precision analytical tool to describe the impact of network structure, particularly degree heterogeneity and degree correlations, on synergistic contagions.

Despite its importance, the mechanisms underlying the sealing capacity remain poorly understood, and their quantitative evaluation is rarely explored. This study starts from the influence of gas transport channels, and summarizes the key factors that affect sealing capability.

In this study, we designed and synthesized two photosensitive modules, with naphthalene-modified triphenylamine derivative (NA-TPA) as the donor unit and methylated-viologen-modified benzothiadiazole derivative (DPBT) as the acceptor unit, which can self-assemble into a two-dimensional supramolecular organic framework (SOF) through encapsulation-enhanced donor-acceptor interaction with cucurbit[8]uril (CB[8]) in water. The donor-acceptor SOF can not only self-assemble into two-dimensional nanosheet morphology in water but also exhibit excellent luminescence enhancement performance.

Traditional cross-linking, composites, or microencapsulation methods for preparation of form stable PCMs usually sacrifice part of the phase change enthalpy and recyclability. Based on the basic polymer viscoelasticity and crystallization theories, here, a kind of novel recyclable polymeric PCM is developed by simple solution mixing ultrahigh molecular weight of polyethylene oxide (UHMWPEO) with its chemical identical oligomer polyethylene glycol (PEG).

However, the high viscosity and long relaxation time greatly complicate processing. In industry, solvents, like decalin and paraffin oil, usually disentangle the physical networks and promote final drawability.

Crystallization of polymers from entangled melts generally leads to the formation of semicrystalline materials with a nanoscopic morphology consisting of stacks of alternating crystalline and amorphous layers. The factors controlling the thickness of the crystalline layers are well studied; however, there is no quantitative understanding of the thickness of the amorphous layers. We elucidate the effect of entanglements on the semicrystalline morphology by the use of a series of model blends of high-molecular-weight polymers with unentangled oligomers leading to a reduced entanglement density in the melt as characterized by rheological measurements.
