Always great to have an article online: link.springer.com/article/10.1... Fun work, together with my co-authors. And many thanks to @tuwien.at for providing open access support! #AcademicSky
Decontamination potential of radioactively contaminated wounds with purified clinoptilolite-tuff - Journal of Radioanalytical and Nuclear Chemistry
Purified clinoptilolite-tuff (PCT) has successfully been tested for application in a PCT-doped wound dressing for use in radiolytically contaminated environments. Initial quantitative studies of the capacity of PCT for SrCl2 utilizing 85Sr radiotracered material and CsCl utilizing 134Cs radiotracered material in both aqueous (AQ) and physiological (artificial wound fluid exudate; AWFE) media show that Cs+ capacities for PCT differ slightly (AQ: 1.60 ± 0.05 mmol/g vs. AWFE: 307 1.37 ± 0.07 mmol/g) while Sr2+ capacities are not significantly different (AQ: 0.43 ± 0.01 mmol/g vs. AWFE: 0.41 ± 0.03 mmol/g). Additionally, preliminary qualitative information relating to the selectivity of PCT for Sr2+ and Cs+ vs. Ca2+ has been obtained from these studies. Finally, experiments show the enhanced uptake of radio-Cs and radio-Sr by PCT-doped wound dressings compared to state-of-the-art alternatives.

Not the best of days today. But then late tonight I get this:

"We are pleased to inform you that your manuscript... has been accepted for publication..."

Nice one :-)

Quite happy that we published this article on Tell Brak and its pottery with Archaeological and Anthropological Sciences! It's open access, too: rdcu.be/ezsNo
Many thanks to my co-authors P. Fragnoli @oeai.bsky.social , R. Crocco and F. Balossi Restelli, it was great!

Every publication I read quickly becomes this rabbit hole of more and more information. Luckly, the term has ended and I'm done with grading, so there's time to take a dive 😆 #AcademicSky

Bei Großeinsätzen wie jetzt in Graz kommt es schnell zu Gerüchten und Spekulationen - umso wichtiger ist, darauf zu achten, was gesicherte Information ist. Und im Zweifelsfall lieber weniger als mehr zu teilen. Wer Informationen der Polizei sucht, findet diese bei @polizeistmk.bsky.social #graz1006

Spending half a day to get that one sentence in my publication right. Next day, I write two full pages... Funny how unrelated word count and effort are :-P #AcademicSky #AcademicChatter

Since we’re all talking about it I want to blow up a real female space pioneer, Mae Jemison, an actual astronaut. She’s a graduate of Stanford and Cornel Medical School, served in the peace corps, started an educational nonprofit, and worked for the CDC researching vaccines. That’s a woman in space

Always such a pleasure to have your PhD students show off their great work. Well done Helmut Muckenhuber, presenting his work on a software to calculate the retention of Cr(tmhd)3 in neutron activation. #AcademicSky #MARCconference

FPÖ-Mediensprecher Hafenecker: “Die Zwangsfinanzierung des ORF kann es in dieser Form nicht weiter geben. … Wir werden die Presseförderung neu aufstellen. Und wenn Medien ständig die Inserate kritisieren, werden Sie merken, wie es ohne Inserate ist. Das wird dann auch den STANDARD treffen.”

Ich bin Wissenschaftlerin & Mutter. Eine Kombination, die unvereinbar scheint. Dennoch gehen viele Frauen diesen Weg, der oft sehr hart und einsam sein kann. Es ist mir daher ein Anliegen, das Netzwerk Mutterschaft & Wissenschaft zu bewerben, von Rahel More & Astrid Wirth @univie.ac.at koordiniert
