We conducted a pilot study using a passive radio-wave-based home monitor in individuals with Parkinson disease (PD) with a focus on gait, home activity, and time in bed. We enrolled 7 ambulatory individuals to have the device installed in the bedroom of their homes over 8 weeks and performed standard PD assessments at baseline. We evaluated the abi...
Yttria stabilized zirconia (3 mol% YSZ) ceramics were prepared by Flash-SPS, while allowing high heating rates up to 200 °C/s, which led to the extremely fast densification within a few seconds. The high heating rates had strong impact on sintering mechanisms, in terms of densification and grain growth. While the specimens ended with 5–15 vol% poro...
The present paper studies the material removal evolution, during Plasma Electrolytic Polishing (PeP), on model roughnesses prepared on 1050 aluminum alloy (AA), i.e. a quasi-pure aluminum, used as a model substrate. The results obtained in this study confirm the significance of the applied voltage on aluminum removal. In particular, the minimal vol...
This paper presents the broadband noise analysis of a Counter Rotating Open Rotor (CROR) configuration. The numerical study is based on a hybrid approach: a Large Eddy Simulation (LES) code solves the near-flow field of the CROR configuration and the near-to-far-field propagation is then predicted by a Ffowcs Williams-Hawkings analogy either based ...
SiC was densified by spark plasma sintering (SPS) and the effects of surface modification of the powder particles on its sintering behavior were investigated. The pressure and temperature conditions were set to 50 MPa and 2200 °C, respectively. Specific SPS experiments at a lower temperature (i.e. 1600 °C) was performed to analyze the efficiency of...
Electrospun scaffolds can find numerous applications, including biomedical; for example, tissue engineering. Poly-L-lactic acid is considered suitable for these applications, but its low-thermal stability and its poor mechanical properties limit this polymer use. The aim of this work is to obtain a modulation of the final scaffolds characteristics ...
The influence of anion specificity on the faradaic efficiency relative to aluminum oxidation during electrocoagulation has been reported. While with chaotrope anions, the faradaic efficiency is higher than 1, it is lower than 1 with kosmotrope anions. The origin of this distinction has been ascribed to the ability of anions to cause pitting through...
Actual requirements of the pharmaceutics industry for reliable, safe, long term storage of biopharmaceuticals imply the use of chemically inert glass vials. This can be achieved by applying a barrier coating on their internal surface. In the present work we investigate the hydrolytic resistance of amorphous alumina coatings applied by chemical vapo...
Even though ultrasonication is considered to be an effective method to disperse carbon nanotubes (CNTs), its devastating effects on the nanotubes are often neglected. Here, even mild ultrasonication is found to rapidly extract the inner single-wall CNTs (SWCNTs) from the outer shells of the double-wall CNTs (DWCNTs). As-synthesized DWCNTs are gentl...
Increasing the production of high-performance natural fibres that minimise their impact on the environment is a challenge that flax (Linum usitatissinum L.) cannot address alone. In flax traditional production territories, hemp (Cannabis sativa L.) can be a complementary source of high added value fibres if their yield of long line fibres can be ma...
