Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

open access: yesAdvanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Exploring Microstructure–Physical Property–Corrosion Response Relationship in Intermetallic Compounds of Al‐Cu Bimetallic Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Al‐Cu intermetallic compounds (IMCs) have a significant influence on the properties of Al‐Cu bimetallic interfaces formed in compound casting. This article provides a deeper understanding of microstructure, crystallography, thermal properties, hardness, and corrosion response of Al‐Cu IMCs with the goal of facilitating the optimization of the ...

X‐Ray Tomography Analysis of Damage Mechanisms in Metal Matrix Syntactic Foams During Compression

open access: yesAdvanced Engineering Materials, EarlyView.
In situ synchrotron X‐ray tomography is used to investigate the internal damage mechanisms of AlSi12 metal matrix syntactic foam with ceramic hollow spheres during compressive loading. It is concluded that a homogeneous distribution of the second‐phase filler material results in a sequential collapse in a localized region; this leads to controlled and ...

Micropleated Nanofibrous Filters for High‐Efficiency Submicron Aerosol Filtration: A Comparative Study with Chemical, Biological, Radiological, and Nuclear Gas Mask Filters

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents micropleated filters manufactured by needleless electrospinning. Nanofibers are deposited onto uniaxially pre‐stretched substrates that contract upon release, forming densely packed micropleats. This architecture increases effective surface area without enlarging the filter size, achieving quality factors comparable to those of ...

Effects of CeO2 on Bi2O3-rich Lead-free Sealing Glass Ceramics [PDF]

open access: yes, 2012
传统上,国内外电子与电器设备上的电热管常用的封接材料是含Pb微晶玻璃;但是,由于含Pb玻璃有毒,美日欧及我国等先后采取了相关措施,对封接材料的含Pb量作了严格法律的限制。因此,研制无Pb封接微晶玻璃具有十分重要的意义。本研究作为制备结构材料,对于Bi2O3原料的纯度要求不高,可提取自某些稀土尾矿,CeO2如能应用于封接用无Pb封接微晶玻璃,则对尾矿处理、稀土综合利用和轻稀土大量堆积等问题的解决有积极的作用,且加入少量CeO2可以有效提高封接玻璃与添加铈的合金的结合能力。 本研究在全面深入的调研的基础上 ...

Recycling of inorganic waste in monolithic and cellular glass-based materials for structural and functional applications [PDF]

open access: yes, 2016
The stabilization of inorganic waste of various nature and origin, in glasses, has been a key strategy for environmental protection for the last decades. When properly formulated, glasses may retain many inorganic contaminants permanently, but it must be
