Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

open access: yesAdvanced Functional Materials, EarlyView.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

Terracotta Pipes with Triangular Engravings [PDF]

open access: yes, 2014
The discovery of two smoking pipes from seventeenth-century contexts in Buenos Aires, Argentina, is used to suggest the presence in colonial times of a new set of stylistic norms derived from African traditions that are expressed at a regional scale not ...

Strong ferroelectric and luminescence properties of 0–3 type 0.8BaTiO3–0.2CaTiO3:Pr3+ composite ceramics prepared by cold sintering process

open access: yesJournal of Advanced Ceramics
0–3 type ferroelectric–phosphor composite ceramics cannot be prepared by the traditional solid-state sintering (SSS) method due to the strong chemical reaction between ferroelectrics and phosphors during high-temperature sintering.

High performance of La-doped Y2O3 transparent ceramics

open access: yesJournal of Advanced Ceramics, 2020
As an optical material, Y2O3 transparent ceramics are desirable for application as laser host materials. However, it is difficult to sinter and dense of Y2O3 hinders the preparation of high-quality optical ceramics via traditional processes. In this work,

Fluoride‐Free Adhesives for Low Surface Energy Fluorinated Substrates

open access: yesAdvanced Functional Materials, EarlyView.
A universal, fluoride‐free adhesive achieves a record 4.91 MPa bond strength on PTFE by leveraging amine/amide dipole–dipole interactions, without fluorinated components. This sustainable strategy overcomes the environmental and performance limits of PFAS‐based adhesives, enabling robust, eco‐conscious bonding across diverse materials.

Water Absorption Properties of Cement Pastes: Experimental and Modelling Inspections [PDF]

open access: yes, 2018
An intermingled fractal units’ model is shown in order to simulate pore microstructures as pore fraction and pore size distribution. This model is aimed at predicting capillary water absorption coefficient and sorptivity values in cement pastes.
