Simultaneous Toughening and Strengthening of Ductile Polymer by Rigid Polymeric Fillers: The Role of Interfacial Entanglement.

The modification of thermoplastic polymers is frequently impeded by the inherent contradiction between their toughness and strength. In this study, an effective strategy to significantly improve the mechanical properties of ductile polymers by simply adding a complimentary rigid polymer is introduced. This work uses a semi-crystalline polymer aliphatic polyketone (POK) as the matrix material and a small quantity of polymethyl methacrylate (PMMA) as the rigid polymer, through establishing molecular chain entanglements at the interface to produce POK/PMMA blends with exceptional mechanical property.

Stretchable Primary-Blue Color-Conversion Layer: Crystallization of Phase-Engineered Perovskite Nanocrystals in an Organic Matrix.

Although the use of ultraviolet (UV) light-emitting diode backlight with red, green, and blue color-conversion layers (CCLs) in displays simplifies the manufacturing process and improves display uniformity, research on blue CCLs remains limited and has been mostly reported in the sky-blue region (> 470 nm), which is insufficient to satisfy the Rec. 2020 color standard. As halide perovskites offer a high extinction coefficient, color purity, and photoluminescence quantum yield (PLQY), they become highly competitive color-converting materials for CCLs.

Novel contribution to the taxonomy and molecular phylogeny of scuticociliates (Protozoa): Resolving the non-monophyly of the genus Paranophrys Thompson and Berger, 1965 and the establishment of the genus Anteparanophrys n. gen.

During a field survey of parasitic ciliates diversity in South Korea, a scuticociliate was found in a water sample collected during scuba diving. At first glance, the species looks similar to members of the genus Paranophrys especially P. magna but they differ mainly in the body size and the number of somatic kineties.
