Multi-resistant pathogens are one of the main challenges in health care as resistance genes vastly spread globally. One of the major causes for the dissemination of nosocomial infections is the contamination of medical devices. However, the common au

The electron density is one of the most important parameters to characterise the properties of plasma. Among several other methods microwave interferometry is a well known technique. Two approaches at different fre-quencies are given to show the appl

Summary form only given. The lifetime of fluorescent lamps is typically restricted by the lifetime of their electrodes. During normal operation, the work function lowering emitter material (primarily Ba) is released from the cathode due to evaporatio

A pulsed microwave (MW) plasma was maintained in a waveguide with an ignition pin. Images of the MW discharge were recorded during ignition in ambient air with millisecond time resolution and correlated with measurements of absorbed MW power. This wo
