Sand, mould, pattern and matrix
, 2013 Il s’agit ici de reconsidérer des données concernant un procédé de fonte au sable filmé au Maroc il y a plus d’une dizaine d’années. Partant du double constat de la rareté des traces historiques laissées par cette technique et de sa relative rétivité à une analyse technologique classique en anthropologie filmique (en raison du constant changement d ...

Advanced Materials Technologies, EarlyView.Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

Thermo-Insulating Moulding Sand for thin Walled Castings
Archives of Metallurgy and Materials, 2014 Abstract In paper the selection of the composition and determination of main properties of novel moulding sand was described. The mail goal was to create moulding sand characterized by high thermal insulating properties in relations with low specific weight. This type of moulding sand will find application in thin walled castings with complex geometry,

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion
Advanced Materials Technologies, EarlyView.This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off
