Role of Minimum Adhesive Wear Particle Size in Third-Body Layer Properties

Jean-François Molinari, Son-Jonathan Pham-Ba

We employ a novel discrete element method (DEM) force formulation to simulate adhesive wear and assess the effects of material and loading parameters on the properties of the third-body layer (TBL) formed during sliding motion. The study emphasizes the rol ...

Modified full-face snorkel masks as reusable personal protective equipment for hospital personnel

Patrick Gerber, Mélanie Thérèse Marie Hannebelle, Nitin Arora

Here we adapt and evaluate a full-face snorkel mask for use as personal protective equipment (PPE) for health care workers, who lack appropriate alternatives during the COVID-19 crisis in the spring of 2020. The design (referred to as Pneumask) consists of ...

Reusability of filtering facepiece respirators after decontamination through drying and germicidal UV irradiation

Véronique Michaud, David Vernez, Guillaume Suarez, Kiattisak Batsungnoen

Introduction During pandemics, such as the SARS-CoV-2, filtering facepiece respirators plays an essential role in protecting healthcare personnel. The recycling of respirators is possible in case of critical shortage, but it raises the question of the effe ...

Planar micro-direct methanol fuel cell prototyped by rapid powder blasting

Martinus Gijs, Meng Shen, Ludovic Dovat

We present a planar micro-direct methanol fuel cell (μ−DMFC) fabricated by rapid prototyping powder blasting technology. Using an elastomeric mask, we pattern two parallel microfluidic channels in glass. The anode and cathode of the fuel cell are formed by ...

Fabrication of microfluidic mixers with varying topography in glass using the powder blasting process

Martinus Gijs, Abdeljalil Sayah, Virendra Kumar Parashar

The powder-blasting method is used to fabricate structures with a three-dimensional topography in glass using elastomeric masks. The relation between the mask opening width and the erosion depth is exploited to fabricate microstructures with varying depth ...
