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 ...

Isotope ratio mass spectrometry

The Analyst, 2009
Isotope Ratio Mass Spectrometry (IRMS) is a specialized technique used to provide information about the geographic, chemical, and biological origins of substances. The ability to determine the source of an organic substance stems from the relative isotopic abundances of the elements which comprise the material.

Testing gravity with Extreme-Mass-Ratio Inspirals


Extreme-mass-ratio inspirals consist of binary systems of compact objects, with orders of magnitude differences in their masses, in the regime where the dynamics are driven by gravitational wave emission. The unique nature of extreme-mass-ratio inspirals

Mass ratios of the light quarks

Physical Review Letters, 1992
We derive a consistent set of light quark mass ratios which are compatible with the available constraints of chiral symmetry treated to next-to-leading order. Also required as input is resonance saturation of a set of low-energy amplitudes, in particular for the pion and kaon electromagnetic mass difference.
