Key to recycling

~ Matheus A. Tunes ~ Leave a comment

From Montanuniversität Leoben: https://www.unileoben.ac.at/en/newsdetail/schluessel-zum-recycling For almost a century, commercial aluminum materials have been developed and optimized for high performance in specific applications within strict chemical confines of industrially established alloy classes. The requirements associated with sustainable lightweighting concepts call for new strategies that offer a broader property portfolio with a better trade-off between formability, achievable … Continue reading Key to recycling

On “alien technology” and materials science

~ Matheus A. Tunes ~ Leave a comment

We should be categorical here: the question if we are alone in the Universe remains yet unanswered. Nevertheless, several government bodies are now publicizing the issue with enormous coverage by the mass-media, and these facts has also motivated my attention to the problem from a scientific perspective. In a recent public report, the US intelligence … Continue reading On “alien technology” and materials science

Solar cycle 25 and space weather forecast

~ Matheus A. Tunes ~ Leave a comment

The coming months will test a new prediction that — contrary to most expectations — forecasts one of the strongest solar cycles on record. Sunspots are part of an 11-year up-and-down cycle observed since 1610, “one of the oldest data sets that humans have created,” says Dean Pesnell (NASA Goddard), a solar cycle expert. The sunspot … Continue reading Solar cycle 25 and space weather forecast

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

Aluminium alloy research could benefit manned space missions

~ Matheus A. Tunes ~ Leave a comment

Great news coverage of our article by Tim Oscroft! https://www.hud.ac.uk/news/2020/december/alloy-research-manned-space-missions-benefits/ Manned space missions in spacecraft made of aluminium that is light yet resistant to radiation could be a step nearer following research involving a world-leading facility at the University of Huddersfield. The MIAMI-2 – Microscopes and Ion Accelerators for Materials Investigations – facility has helped Dr Matheus Tunes investigate … Continue reading Aluminium alloy research could benefit manned space missions
