Polymer-derived ceramics (PDCs) exhibit excellent properties and are compatible with many shaping techniques due to the liquid character of the preceramic polymers (PCPs). Furthermore, their properties are adjustable by modifying the precursor composition ...
The growing needs for human healthcare have driven the development of wearable devices for monitoring the health status of an individual. Polymers represent a promising platform for such devices due to their ability to form an intimate contact between soft ...
The Centre Beaubourg of Paris, now known as the Centre National d'Art et de Culture Georges Pompidou, conceived by Piano+Rogers Architects and Ove Arup & Partners, between 1971 and 1977, represents one of the rare synthesis of the architectural, constructi ...
The purpose of this project is to fabricate a mould etched by KOH for PDC casting and produce the fist PDC using this method. Casting for PDC is a known process, it has been done with PDMS moulds created from Si masters. Si moulds have also been fabricated ...
Permeability of fibrous microstructures is a key material property for predicting the mold fill times and resin flow path during composite manufacturing. In this work, we report an efficient approach to predict the permeability of 3D microstructures from d ...
Polymer-derived ceramics are known for their resistance to high temperatures and harsh environments as well as property tunability and compatibility with various shaping techniques. We demonstrate here a new hierarchical micro-manufacturing process combini ...
Additive manufacturing offers the opportunity to produce complex geometries from novel alloys with improved properties. Adapting conventional alloys to the process-specific properties can facilitate rapid implementation of these materials in industrial pra ...
This paper proposes a novel technique for the design of miniaturized Ka-band filters based on locally resonant metamaterials (LRMs), which are fabricated monolithically using lost wax casting. We implement ultra-small metamaterial filters by exploiting a n ...
Rapid solidification of Al-Cu droplets of eutectic composition was carried out using Impulse Atomization (a type of drop tube). Two distinct morphologies were observed: an irregular undulated eutectic assumed to form during recalescence, followed by a regu ...
Laser surface remelting at various velocities has been employed to study the selection of microstructures of high-purity Fe-C-Si alloys containing nominally 3.2 to 4.2 wt.% C and 1 to 3 wt.% Si. The microstructure of the remelted region consisted of metast ...
