High performance transparent polymeric materials are of great interests in many fields including automotive and electronics. Conventional transparent plastics like polycarbonate (PC) and poly(methyl methacrylate) (PMMA) possess relatively unsatisfactory mechanical performance, while high performance polymeric systems like solid-state drawn high-density polyethylene (HDPE) typically have an opaque appearance, limiting applications where both mechanical and optical properties are required. In this study, we successfully combined high transparency and high strength in HDPE films by carefully controlling processing parameters

Particle‐like magnetic textures with nanometric sizes, such as skyrmions, are potentially suitable for designing high‐efficiency information bits in future spintronics devices. In general, the Dzyaloshinskii–Moriya interactions and dipolar interactions are the dominant factors for generating nonlinear spin configurations. However, to stabilize the topological skyrmions, an external magnetic field is usually required. In this study, the spontaneous emergence of skyrmions is directly observed, together with the unique successive topological domain evolution during the spin reorientation transition in a neodymium–cobalt (NdCo5) rare‐earth magnet. On decreasing the temperature, nanometric skyrmion lattices evolve into enclosed in‐plane domains (EIPDs) similar to mini bar‐magnets with size below 120 nm. The internal magnetization rotates with magnetic anisotropy, demonstrating the ability to manipulate the mini bar‐magnets. The nanoscale EIPD lattices remain robust over the wide temperature range of 241–167 K, indicating the possibility of high‐density in‐plane magnetic information storage. The generation of spontaneous magnetic skyrmions and the successive domain transformation in the traditional NdCo5 rare‐earth magnet may prompt application exploration for topological magnetic spin textures with novel physical mechanisms in versatile magnets.

Advanced composite materials reinforced with high performance fibers like carbon, glass, aramid or ultra-high molecular weight polyethylene are widely used as lightweight materials in the fields of automotive, aerospace, sports and protection. However, nearly always these composites are opaque and/or they absorb light, which greatly limits their application in areas where high optical

This article focuses on the two-party static game between market supervisory organization and peer-to-peer (P2P) lending platform. Considering 4 game modes with both “strong supervision” and “weak supervision” of market supervisory organization and “compliance management” and “noncompliance management” of P2P lending platform, the paper establishes a static game model between P2P lending platform and market supervisory organization and solves the market equilibrium solutions. Based on income, cost, disguised cost, and fine of P2P lending platform and income, cost, and reward of market supervisory organization, it discusses conditional strategies that P2P lending platform selects “compliance management” or “noncompliance management” and that market supervisory organization selects “strong supervision” or “weak supervision,” respectively. Furthermore, the relevant influencing factors are analyzed which come from 18 P2P lending platforms in Guangdong Province of China, and the conclusions were in good agreement with the actual market. The research has scientific guiding significance.
