We show that thin layers of EuO, a ferromagnetic insulator, can be achieved by topotactic reduction under titanium of a Eu2O3 film deposited on top of a graphene template. The reduction process leads to the formation of a 7-nm-thick EuO smooth layer, without noticeable structural changes in the underlying chemical vapor deposited graphene. The obtained EuO films exhibit ferromagnetism, with a Curie temperature that decreases with the initially deposited Eu2O3 layer thickness. By adjusting the thickness of the Eu2O3 layer below 7 nm, we promote the formation of EuO at the very graphene interface: the EuO/graphene heterostructure demonstrates the anomalous Hall effect (AHE), which is a fingerprint of proximity-induced spin polarization in graphene. The AHE signal moreover persists above Tc up to 350 K due to a robust super-paramagnetic phase in EuO. This original high-temperature magnetic phase is attributed to magnetic polarons in EuO: we propose that the high strain in our EuO films grown on graphene stabilizes the magnetic polarons up to room temperature. This effect is different from the case of bulk EuO in which polarons vanish in the vicinity of the Curie temperature Tc=69 K.

Recycled glass material is made from hundred percent recycled bottle glass and consume less energy than re-melt technology. It also uses no additives in the manufacturing process allowing the recycled glass material, in principal, to go back to the recycling stream after end-of-use, contributing to the circular economy with a low ecological impact. Previous research with low temperature fused recycled bottle glass was developed for the manufacturing of interior tiles and commissioned by an architectural practice for a new build which was based on sustainable principles. The research considered objective mechanical criteria such as flexural bending strength, stability and stain and scratch resistance. It also emphasized on aesthetic development such as colouring, translucency, texture and reproducibility. Continuing from previous research results the material is believed to behold properties in which it can be used for other architectural applications such as pavements, wall cladding, or even non-structural furniture. This is a relatively new architectural material of which there has been little publications in material specifications or processes for mechanical testing. The aim of this paper is to investigate the procedure for testing the recycled glass material for impact resistance, so it can be applied to pavements and other surfaces which are at risk of impact during service. A review of different impact test procedures for construction materials was undertaken, comparing methodologies and international standards applied to other materials such as natural stone, ceramics and glass. A new drop weight impact testing machine was designed and manufactured in-house to perform these tests. As a case study, samples of the recycled glass material were manufactured with two different thicknesses and tested. The impact energy was calculated theoretically, obtaining results with 5 and 10 Joules. The results on the material were subsequently discussed. Improvements on the p

The flow code ANSYS CFX has been used to calculate the flow around two model propellers, DTMB P4679 and DTMB P4718, operating with a 7.5 shaft inclination. Pressures on the face and back of the blades have been compared with measured values. The predictions agree well with measured average pressures and in the amplitude of the variations in pressure. Predictions of the phase of the pressure variations are not as good. The ANSYS CFX predictions also compare favourably with the predictions of panel methods, especially with regard to the amplitude of the pressure variations., Text in English; abstract in French and English.
