Simultaneous Enhancement of Mechanical and Dielectric Performance of Polypropylene Composites by Introducing an External Elastic Crystal

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A hierarchical crystalline structure for recyclable polypropylene insulation in high‐voltage cables is presented. This architecture integrates rigid isotactic polypropylene spherulites with an elastic crystalline network to balance load‐bearing capacity and ductility.

The Weibull-Gamma Distribution: Properties and Applications

open access: yesEntropy, 2019
A new member of the Weibull-generated (Weibull-G) family of distributions—namely the Weibull-gamma distribution—is proposed. This four-parameter distribution can provide great flexibility in modeling different data distribution shapes.

Linear‐Nonlinear‐Linear Sandwich‐Structured Polymer Composites With Metal‐Organic Framework (MOF)‐Enhanced Insulating Layers and Horizontally Oriented Nanotube‐Filled Polarization Layer for High Energy Storage Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A linear‐nonlinear‐linear (LNL) sandwich dielectric film was rationally designed for high energy storage. Its outer linear layers are MOF (ZIF‐8)‐enhanced PEI composites (EZ), and the middle nonlinear layer is an electrospun‐hot‐pressed P(VDF‐HFP)/TNTs composite (PT) with horizontally oriented TNTs.

Evaluation of three methods for estimating the Weibull distribution parameters of Chinese pine (Pinus tabulaeformis )

open access: yesJournal of Forest Science, 2008
Weibull distribution was used to fit tree diameter data collected from 86 sample plots located in Chinese pine stand in Beijing. To estimate the Weibull distribution parameters, three methods [namely maximum likelihood estimation method (MLE), method of ...

Glycerol‐Modified Biphasic Silicone Gel for Synergistic Thermal Transport and Dielectric Reliability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A surfactant‐free glycerol‐modified biphasic silicone gel establishes metastable liquid interfaces that simultaneously enhance phonon transport and induce deep traps (1.28 eV), enabling synergistic electrothermal performance of enhanced thermal conductivity (+33.3%), thermal diffusivity (+48.3%), and DC breakdown strength (+57.6%) with suppressed space

Integrated modeling of the sports and reliability data: Implications of the probabilistic model and deep learning approaches

open access: yesAlexandria Engineering Journal
In this paper, we consider the evolution of a new probability distribution called the exponential flexible Weibull distribution. The proposed exponential flexible Weibull distribution is obtained by combining the flexible Weibull extension with the ...
