Improving Dose Calculations In Electron-beam Radiation Therapy
The finite range of electrons in tissue makes electron beams a useful radiation treatment modality for many tumour sites. However, the simplistic methods of dose calculation in current clinical use lack sufficient accuracy in many situations of clinical importance. This thesis rests on the premise …

Creation and modification of polymeric materials using electron beam radiation
This dissertation begins with a review of radiation chemistry and a number of important variables which can influence the chemistry occurring in irradiated polymeric materials. Following the literature review, four different studies involving the electron beam irradiation and subsequent …

Electron beam irradiation of polystyrene/poly(vinyl methyl ether) blends
The effects of electron beam radiation on the rheological behavior of a polystyrene/poly(vinyl methyl ether) blend as a function of absorbed dose, composition, and temperature, were investigated. The purpose of this research has been to modify the viscosity of polystyrene by studying the influences …

Time-resolved spectroscopic investigation of N2/H2 nanosecond pulsed discharges and EUV-induced low-temperature plasmas
… pulsed discharges (NPD) and a mono-energetic electron-beam radiation (EBR) source. The overarching goal is to separate driver-specific spectral fingerprints from shared low-pressure kinetics, and to identify spectroscopic diagnostics that are robust, quantitative, and deployable under …

Rheological and Mechanical behaviour of Block copolymers, Multigraft copolymers and Block copolymer Nanocomposites
… based TPEs are cross-linked in presence of electron beam (EB) radiation for developing materials with superior properties. The electron beam radiation has the ability to alter material parameters at molecular level for enhancing the macroscopic properties. The desirable physical and chemical …

Friction, wear and mechanical properties of electron beam modified PTFE-based rubber compounds
Die inhärenten elastomeren Eigenschaften von Gummiwerkstoffen sind im Vergleich zu Thermoplasten in vielen Spezialanwendungen vorteilhaft. Jedoch sind ihre schlechten Reibungs- und Verschleißeigenschaften ein wesentlicher Nachteil besonders bei tribologischen Anwendungen. In der vorliegenden Arbeit …
