The Atlantis massif is a domal submarine seamount close to the mid-Atlantic Ridge at 30 °N. Close to the crest of the Massif, the Lost City hydrothermal field (LCHF) has been active for at least 120,000 years, venting fluids with a temperature of 40-90 °C. 5 km north of Lost City, a temperature profile has been measured in IODP Hole 1309D, with a near-conductive thermal gradient of ~100 °C/km ...

The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes place. The temperature of the material during the reaction is one of the most influencing parameter and has to ...

The application of pulsed electric fields (PEF) is well known in the food industry as an advanced technology for mass transfer improvement. A new potential adaptation area of PEF could be extracting a valuable antioxidant called polyphenol from wet olive pomace (WOP) which is a by-product of olive oil production. The modelling includes the PEF effects on the WOP which is flowing through a ...

In clean coal technologies, improving energy conversion efficiency is one of the most important directions. Compared to traditional subcritical power plants, pressure-increased supercritical power plants improve the plant energy efficiency from 35% up to 45%. This work presents a study of the thermodynamic behaviour of the water cycle in coal-fired boilers in response to the changes in energy ...

The subsurface thermal structure in presence of groundwater recharge/discharge has been obtained by applying the Robin type boundary condition at the earth’s surface. The Robin type boundary condition involves the effect air temperatures at the surface which are taken as exponentially varying with time and the initial condition which is taken as exponential function of depth. The numerical ...

In this work, a piezoelectric tactile sensor will be designed and simulated using COMSOL Multiphysics®. The sensor is designed in order to assess the pressure exerted on the human body while the robotic surgery is performed. The sensor consists of a rigid and compliant cylindrical element. A circular PDMS (Polydimethylsiloxane) film is sandwiched between the rigid cylinder and the base plate to ...

Numerical simulation can be advantageously employed to predict the main cell features (e.g., the reaction rate distribution on the electrodes, the cell voltage, or the electrolyte temperature) in order to optimize the design and operational conditions of the process. In this poster, we describe two complementary computational approaches applied to a molten salt electro-refiner for ...

The rotary kiln process is a commonly practiced method in the industry for producing sponge iron using coal. In the industry, there have been recent reports of premature failures of certain air tubes in a rotary kiln. Most of those cases have concentrated on those air tubes which run into the kiln around the middle portion of the kiln. This research work aims at identifying the probable cause of ...

An affordable and user friendly digital stethoscope with wireless connectivity is envisioned as an extremely useful tool for heart patients. Our design couples the acoustic pressure from normal stethoscope to a smartphone microphone in an enclosure that is then digitized and sent to doctor for diagnosis.

Plasmonic metallic nanostructures have been demonstrated an effective way to enhance the light emission efficiency in LEDs. Here, we propose a design of white LEDs that combining dielectric silicon nanopillar array in the color-converting layer. By investigating theoretically the guided mode caused by the nanopillar array-waveguide system, we demonstrate that the silicon nanopillar arrays enable ...
