Preparation of Mullite Fiber Reinforced Mullite Composites

IOP Conference Series: Materials Science and Engineering, 2019
Abstract In this paper, mullite fiber reinforced mullite composites were prepared by stitched structural perform, the silica sol and alumina sol. In order to improve the compatibility of mullite fiber and silica sol matrix, interface coating was made by infiltration. The composites were prepared by the method of liquid phase infiltration,

Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

Journal of Applied Polymer Science, EarlyView.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,

Investigation of Microscopic Nonmetallic Inclusions in Powder Metallurgical High‐Speed Steels

steel research international, EarlyView.
Methods for inclusion analysis are evaluated for suitability. Various powder metallurgical steels in different processing states are characterized. SEM/EDS data are further analyzed using analytical and statistical approaches. A thermodynamic method for determining inclusion phase composition is tested.

Ceramic Raw Materials and Technological Choices in Iron Age Tyre (Lebanon): A Multiproxy, Fabric‐Based Approach

Archaeometry, EarlyView.
ABSTRACT This study presents a systematically integrated, multiproxy characterisation of Iron Age ceramics from Tyre (Lebanon). Ninety‐nine ceramic samples from stratified Iron Age contexts on Tyre's Acropolis, together with a small Late Bronze Age and raw‐clay reference set, were analysed using petrography, microfossil identification, X‐ray ...
