President Trump signs Memorandum on Space Policy Directive

~ Matheus A. Tunes ~ Leave a comment

Section 1. Policy. The ability to use space nuclear power and propulsion (SNPP) systems safely, securely, and sustainably is vital to maintaining and advancing United States dominance and strategic leadership in space. SNPP systems include radioisotope power systems (RPSs) and fission reactors used for power or propulsion in spacecraft, rovers, and other surface elements. SNPP … Continue reading President Trump signs Memorandum on Space Policy Directive

Detecting Li within electron microscopes is a deep challenge…

~ Matheus A. Tunes ~ Leave a comment

Low-energy characteristic X-rays (physicists like the term 'soft X-rays' =]...) are problematic to detect and quantify using existing Energy Dispersive X-ray (EDX) spectroscopy techniques. For example, within Mg-Li alloys, proper detection of Li remains a significant challenge. Very interesting work on instrumentation of EDX coupled with scanning electron microscopy (SEM) has now addressed to this … Continue reading Detecting Li within electron microscopes is a deep challenge…
