Jarosite formation in deep Antarctic ice provides a window into acidic, water-limited weathering on Mars

 
Formation of the mineral of jarosite (hydrated iron potassium sulfate) at great depths in Antarctic glaciers has been identified for the first time.
This result was also obtained thanks to the analysis of the powders with XANES, with SYNCROTRON RADIATION, and confirms the hypothesis according to which the sediments rich in jarosite identified on the surface of Mars by NASA's Rover Opportunity, would be linked to the presence of large ice caps that covered part of the red planet in the ancient geological past.

Identificata per la prima volta la formazione del minerale di jarosite (solfato idrato di ferro e potassio) a grandi profondità nei ghiacciai Antartici.
Questo risultato è stato ottenuto anche grazie all'analisi delle polveri con le XANES, con RADIAZIONE DI SINCROTRONE, e conferma l’ipotesi secondo la quale i sedimenti ricchi di jarosite individuati sulla superficie di Marte dal Rover Opportunity della NASA, sarebbero legati alla presenza di grandi calotte di ghiaccio che hanno coperto parte del pianeta rosso nell’antico passato geologico.

The Nobel Prize in chemistry to John B. Goodenough

 


In the first raw from left to rigth: Takeshi Egami, Antonio Bianconi, John Goodenough, Charles P. Slichter.

Today Oct 9, 2019 the scientific community of Superstripes is very happy for the announcement of the Nobel Prize in chemistry, to John B. Goodenough.
We all congratulate with John for the discovery of Lithium batteries but we all think that : "John finally won the prize" since he made so many other beautiful discoveries in the science of quantum materials.
John B. Goodenough with Alex K. Muller [nobel Laureate] and Lev Gor'kov [Ugo Fano Gold Medal] has partecipated at the first Stripes conference (held in 1996) and at many following Stripes and Superstripes conferences where he presented the key role of pseudo Jahn Teller polaron stripes and for new of phase segregation in perovskite high Tc superconductors.

The picture was taken at the Sripes conference held in Rome in 2004
