1. Short Pulses in Engineered Nonlinear Media
Sammanfattning : Short optical pulses and engineered nonlinear media is a powerful combination. Mode locked pulses exhibit high peak powers and short pulse duration and the engineered ferro-electric KTiOPO4 facilitates several different nonlinear processes. LÄS MER
2. Pulsed Electric Field Food Treatment and Low Frequency Bioelectromagnetics
Sammanfattning : This thesis is divided in two parts, both of which address the interaction between biological cells (especially cell membranes) and electromagnetic fields. The first part deals with the application of intense pulsed electric fields (PEF) in foods. It is intended to be a non-thermal method to inactivate microorganisms. LÄS MER
3. Pulsed Electric Field Treatment of Plant Tissue
Sammanfattning : A pulsed electric field (PEF) is a newly emerged non-thermal food processing technology which has characteristic effects on the cell membrane. PEF processing involves subjecting food to short, repeated pulses of a high electric field between an anode and a cathode. LÄS MER
4. Electropermeabilization in Experimental Tumour Treatment: Dosimetry and Tissue Effects
Sammanfattning : Short, electric high-voltage pulses can be used to transiently increase the permeability of cell membranes without significant loss of cell viability. During this period of time, extracellular and normally non-permeant, molecules are accessed the cytoplasm and the cell nucleus. LÄS MER
5. Effects of Pulsed Electric Fields on Plant Tissue
Sammanfattning : The interaction between biological cells and external electric fields has been of interest by scientists for several decades. Exposure of the cells to electric fields leads to various kinds of biophysical and biochemical responses. These responses can be used to characterize cell properties and/or to manipulate cell characteristics. LÄS MER
