Microbiologically influenced corrosion (MIC) is known to be a dangerous process in ship tanks due to its rapid and yet unpredictable occurrence, leading to extremely fast local corrosion, possibly jeopardizing the structural integrity, in a relatively short time. This project focuses on a fundamental understanding of MIC processes in ship...

The optical microscope onboard the Phoenix spacecraft has returned color images (4 ?m pixel?1) of soils that were delivered to and held on various substrates. A preliminary taxonomy of Phoenix soil particles, based on color, size, and shape, identifies the following particle types [generic names in brackets]: (1) reddish fines, mostly unresolved...

This thesis describes method development in TEM-related techniques and their application to the study of nanoprecipitates and low-dimensional structures. The work is divided into two parts. • The first part is focused on the structures of nanoprecipitates found in Al-Co, Al-Ni and Al-Fe-Zr alloys. • The second part describes the effect of...

A combined use of fluorescence and light microscopy is a powerful approach to further increase our understanding in biological systems of structure-function relations at cellular and sub-cellular levels. The power of fluorescence microscopy (FM) is to spectrally resolve and visualize individual proteins with endogenous or immuno- fluorescent...

This paper shows the benefit of using transmitted light microscopy together with a Z-scanning software in fractographical analyses of glass. The strength of glass is largely dependent on processes that happen at the microscale. In this research, 52 plates were fractured in a biaxial tensile test. These were divided into five categories according...

Cancer is one of the most well-known groups of diseases that finds its cause in cells having chromosomal aberrations. How and why these aberrations can occur is one of the most important questions asked in modern molecular biology. In the last decades it has become clear that gene regulation in the nucleus, where the chromosomes reside, is...

While fluorescence microscope systems remains an essential tool in modern biology and medical work, no compact instrumentation has been developed for the rapid calibration of such systems. Almost invariably results are presented in terms of the [AU], "arbitrary units". To remedy this situation we have developed a small, portable instrument - the...

Based upon a collection of compact LEDs (light-emitting diodes) and a compact photodiode, we have developed a calibration tool for fluorescence microscopes that are used as digital imaging devices. The entire device (excluding a USB connector) measures 25 mm x 80 mm x 12 mm. Virtually all commonly-used fluorophores can be simulated with one of...

In the present thesis the combination of real-time electricalmeasurements on nano-sampleswith simultaneous examination by transmission electron microscope (TEM) is discussed. Application of an electrical current may lead to changes in the samples thus the possibility to correlate such changes with the corresponding I-V measurements is very...

Cathodoluminescence (CL), the excitation of light by an electron beam, has gained attention as an analysis tool for investigating the optical response of a structure, at a resolution that approaches that in electron microscopy, in the nanometer range. However, the application possibilities are limited because the use of transparent substrates,...

Aberrations, scattering and absorption degrade the performance light-sheet fluorescence microscopes (LSFM). An adaptive optics system to correct for these artefacts and to optimize the light-sheet illumination is presented. This system allows a higher axial resolution to be recovered over the field-of-view of the detection objective. It is...

In the last decades, many research teams working at Terahertz frequencies focused their efforts on surpassing the diffraction limit. Numerous techniques have been investigated, combining methods existing at optic wavelength with THz system such as Time Domain Spectroscopy. The actual development led on one side to a resolution as high as ?/3000...

We performed terahertz near-field experiments on single rectangular holes with various lengths grown on an electro-optic crystal substrate with ?/100 resolution. We find that the near-field amplitude becomes proportionally larger as the rectangle becomes narrower, strongly suggesting that a constant energy passes through even for a very narrow...

Electromigration is a process in which a metallic contact line is thinned by passing a current through it; which occurs due to a gradual displacement of atoms, ultimately leading to destruction of the wire. Despite the active investigations on electromigration for over fifty years, until now there is no general theory of the process and many...
