In this work, the modeling of an industrial scale, single tube, packed bed reactor for steam reforming (SR) application, typically used to provide hydrogen for ammonia synthesis, is discussed. The tightly coupled mass, energy, and momentum equations used to describe the system have been ... En savoir plus
Pulsed Electric Field (PEF) technology is gaining much attention in the food industry, as it offers unique advantages in terms of food safety, preservation of the organoleptic and nutrients properties, and low energetic requirements. Winemaking processes, in particular, can greatly ... En savoir plus
In this paper a specific version of radiation collecting troughs is investigated. The trough arrangement has a shape which is a combination of a circular arc and adjacent parabolic curve pieces based on a paper by Tripanagnostopoulos [1]. An absorbing tube can be placed at varying ... En savoir plus
There is an increasing demand for aerosol devices from E-cigarettes to drug delivery devices with precise dosage. [1][2] The aim of this article is to investigate a Poly-Si micro heater in a vapor generator device. In order to calculate the amount of vapor production, temperature ... En savoir plus
The monocrystalline semiconductor nanowires (NWs) attract great interest as they reveal new properties that differs from the ones of the bulk equivalents. In addition to small size (10-100 nm diameter), one of their advantages is extremely high surface to volume ratio. This determines ... En savoir plus
Residual Gas Analyzers (RGA) are often used to measure background gases and contaminations in vacuum systems. An ionizer is used to ionize gas molecules and these ions are accelerated and focused by an electrical field from the ion source to form an ion beam. The ions can be ... En savoir plus
The versatility of the 3D printing technology has allowed developing originally structured catalysts for interesting reactions, for instance, the 0.5wt.%Fe/SiC monoliths for the treatment of industrial wastewater. These monolithic structures, manufactured by Robocasting, have ... En savoir plus
Three-dimensional (3D) printed 0.52 wt.% Fe/SiC monoliths with interconnected channels, fabricated by direct ink printing or Robocasting, are feasible and robust catalysts for the hydroxylation of phenol to dihydroxybenzenes using hydrogen peroxide as oxidant in aqueous media [1]. ...

Industrial catalytic processes require tailored catalysts with an optimized performance to reduce energy consumption and waste products. Besides an optimum temperature, pressure, and composition, the distribution of active material can be seen as a valuable additional design variable. ... En savoir plus
Laser-Induced Forward Transfer (LIFT) is a direct-write technique for transferring small volumes (even picolitres) of material through laser irradiation. The characteristics of this material can be in a wide range of viscosities and can respond to different rheological behaviors, from ... En savoir plus
