2019-5-25 · This study proposes a simple and novel synthesis route for rhoohedral single crystals (<2 μm) of magnesite. This synthesis can be summarized by two main sequential reactions: (1) aqueous carbonation of synthetic brucite (Mg(OH)2) by injection of CO2 in a highly alkaline medium (2 m NaOH) at aient temperature (∼20 °C), leading to precipitation of platy-compacted aggregates of dypingite

Biography. Biography: Luca Pezzato Abstract. Plasma Electrolytic Oxidation (PEO) is a very promising process that can enhance the corrosion and wear resistance by producing a relatively thick, dense and hard oxide ceramic coating on light alloys. The corrosion and wear behaviour of the treated samples strongly depends on some process parameters: current density, voltage, treatment time and

This paper represents an experimental study about the effect of curves related to thermosyphons and heat pipes with different active fluids and inclination angle at the thermal efficiency. The nanofluid utilized in this work is an aqueous soluble of Al 2 O 3 nanoparticles with 35 nm diameter in pure water. The test saturation level of nanoparticles is 0%, 1%, and 3%wt.
The present work investigates a narrow range of secondary dendrite arm spacing (SDAS), in an as-cast A356 alloy with and without copper (Cu) additions. Cu was added to the base A356 alloy melt to reach the target concentration of 0.5 and 1 wt.%. Samples were selected from 3 different positions within the cast plate, offering 30, 35, and 40 μm SDAS variants.
ETH researchers have recently been able to monitor the corrosion of bioresorbable magnesium alloys at the nanoscale over a time scale of a few seconds to many hours. This is an important step towards accurately predicting how fast implants are resorbed by the body to enable the development of tailored materials for temporary implant appliions.
