Classical and Bayesian Inference for the Two-Parameter Chen Distribution with Random Censored Data

open access: yesAxioms
This study explores classical and Bayesian estimation for the two-parameter Chen distribution with randomly censored data, where censoring times follow an independent two-parameter Chen distribution with separate shape and scale parameters.

Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

Ionic Liquid (IL) Compatibilization of Macropore‐Infused Nanocomposite Emulsion Thermosets (MINETs) for Structural Ion Transport

open access: yesAdvanced Materials Interfaces, EarlyView.
Macropore‐infused nanocomposite emulsion thermosets (MINETs) offer tunable multifunctionality due to their incorporation of structural resin, functional nanoparticles, and working fluid stabilized by surfactant. Here we show that if ionic liquid working fluids are introduced, structural capacitive (conductive particles) or separator (insulating ...

Bilayered PEDOT:PSS–Collagen Scaffolds as Functional Architectures for Tissue Engineering

open access: yesAdvanced Materials Interfaces, EarlyView.
A bilayered scaffold integrates collagen and PEDOT:PSS as distinct yet interconnected 3D matrices, preserving their fibrillar and conductive characteristics. Spatial compartmentalization enables independent tailoring of each domain while maintaining mechanical stability and compatibility with electrochemical monitoring, providing a multifunctional ...

Conformal Coating and Transfer of 2D Nanomaterials via Dynamic Interface Engineering

open access: yesAdvanced Materials Interfaces, EarlyView.
This review discusses conformal coating and transfer of two‐dimensional (2D) nanomaterials with a focus on dynamic interface engineering. By actively regulating nanosheet transport and interfacial contact during film formation, recent dynamic coating strategies overcome the limitations of conventional passive approaches and enable geometry‐adaptive ...

The Development of a 3D-Printed Compliant System for the Orientation of Payloads on Small Satellites: Material Characterization and Finite Element Analysis of 3D-Printed Polyetherketoneketone (PEKK)

open access: yesAerospace
This article focuses on the development of a 3D-printed 2-degree-of-freedom (DOF) joint for the payloads’ orientation on small satellites. This system is a compliant mechanism, meaning that this monolithic system composed of cross-axis flexural pivots ...
