Investigations of Non-thermal Microwave Effects Using Hybrid Conventional/microwave Heating Calorimetry
A hybrid calorimeter is described whereby the test specimen may be heated using either hot air and/or microwave radiation. Thus it is possible to study phase transitions of materials under conditions ranging from purely conventional heating to pure microwave heating or mixtures thereof. Measurements using silver iodide showed that its phase change from the low temperature β-phase to the high te...
متن کاملStructure-property relations in crystalline L-leucine obtained from calorimetry, X-rays, neutron and Raman scattering.
We have studied the amino acid L-leucine (LEU) using inelastic neutron scattering, X-rays and neutron diffraction, calorimetry and Raman scattering as a function of temperature, focusing on the relationship between the local dynamics of the NH(3), CH(3), CH(2) and CO(2) moieties and the molecular structure of LEU. Calorimetric and diffraction data evidenced two novel phase transitions at about ...
متن کاملBimodal Imaging Using Neutrons and X-rays
Experiments that combines the information from two different radiation sources can provide more information than experiments using single radiation sources. This claim was confirmed using the bimodal installation at the thermal neutron imaging beamline NEUTRA at Paul Scherrer Institut. This installation is equipped with a 60-320kV X-ray source and is used for mid-sized samples. The combination ...
متن کاملDiffractive imaging using partially coherent x rays.
The measured spatial coherence characteristics of the illumination used in a diffractive imaging experiment are incorporated in an algorithm that reconstructs the complex transmission function of an object from experimental x-ray diffraction data using 1.4 keV x rays. Conventional coherent diffractive imaging, which assumes full spatial coherence, is a limiting case of our approach. Even in cas...
متن کاملBiometric identification using knee X-rays
Identification of people often makes use of unique features of the face, fingerprints and retina. Beyond this, a similar identifying process can be applied to internal parts of the body that are not visible to the unaided eye. Here we show that knee X-rays can be used for the identification of individual persons. The image analysis method is based on the wnd-charm algorithm, which has been foun...
