Europeans spend between 80% to 90% of their time indoors, for example at home, school, office, and other public buildings. Besides, due to energy-saving measures in buildings, natural ventilation is reduced leading to the accumulation of indoor air pollutants. Consequently, indoor air ... Read More

Increasing energy demands in society have led to intensive fossil fuel usage, resulting in increasing carbon dioxide (CO2) emissions, one of the most significant greenhouse gases and major contributors to global warming. Considerable efforts have been made towards CO2 capture, storage, ... Read More

Nowadays, surge protection devices are widely used in electrical grids to suppress over voltages during transient conditions caused by voltage surges and to prevent damages of industrial or household devices. The working principle is based on the initiation of an arc with a burning ... Read More

Used for welding, cutting, deposition by projection, for the treatement of waste, or in analysis for ICP torches, for the synthesis of high purity silica or for the manufacture of nanometric powders or nanoparticules, thermal plasmas are fundamental in processing of materials and in ... Read More

Linear Induction Motor (LIM) has been identified as a key element for electromagnetic launching technology. The stator part of the motor when energized induces a linearly moving magnetic field which consequently produces a thrust force on the rotor part of the motor. Thus it accelerates ... Read More

Chipmakers widely use the plasma-enhanced chemical vapour deposition (PECVD) technique for depositing thin dielectric or conducting films on wafers. The primary objective for a deposition process is to have a good flow and species uniformity on the wafer. Typically, a carefully designed ... Read More

In the manufacturing of high voltage electrical equipment, an important step to guarantee a right dielectric design can be carried out through the prediction of a possible occurrence of the corona effect or, in the worst case, of dielectric breakdown, preferably in early stages. For this ... Read More

Exciting plasma in inductive mode is attractive due to the high electron density and the absence of ion interaction with the reactor walls. However, any real system excites plasma at low power in capacitive mode with strong interaction with the walls. The transition from one mode to the ... Read More

At University College London, Applied Analytical Chemistry MSc course, we have used COMSOL Multiphysics as an alternative to laboratory-based student research projects. Use of computational modelling enabled students to complete their research work remotely while gaining experience in ... Read More

Molecules of deuterium in particular rotational and vibrational states are involved in non-equilibrium chemical reactions in tokamak or in neutral beam injector to produce negative ion D-. These molecules are produced in a complex plasma phase where electrons, ions (positive and ... Read More
