xR2H2 - The portable x-ray diffraction and fluorescence analyser powered by Green H2

Last crawled date: 1 year, 10 months ago

The portable X-Ray Diffraction and Fluorescence analyser powered by green H2 (xR2H2) is a scientific instrument for field high precision and efficient analysis of materials. The majority of field researchers in areas such as mineralogy, geology, biology, biomineralogy, physics, geociencies, paleontology, archeology and many others [1,2,3], have a high demand for portable, affordable, and long-lasting scientific instruments for fast and reliable analysis of samples recently collected.
As most of these researches are promoted in remote areas the decrease in the impact on local nature and characteristics demand controlled human interference and eco friendly instruments. Most batteries nowadays are hazardous to the environment, and the use of alternative power sources such as solar, and hydrogen are not only interesting but also highly desired. Solar photovoltaics can hardly generate the power density necessary to power a sufficiently brillant x-ray source, so hydrogen becomes the most interesting green power alternative.
Other than the electric power, this project also proposes two repurposing of byproducts of the electricity generation. The heat that would be originally lost can be redirected in a cogeneration configuration [4,5] to perform an in situ heating experiment in the sample. Also the water generated can be partially or fully stored and controlled redirected to the sample position in a in situ wet/moisture experiment.
