Light detectors made from perovskite crystals see in full colour Most pixels in cameras detect only red, green or blue light. A sensor made from perovskite materials absorbs all three, improving image brightness and resolution.

β€˜A funeral for our careers’: Trump’s science cuts spill onto Canadian turf Researchers in Canada prepare for turbulence in the wake of US funding changes β€” but there’s a silver lining.

Canadian academics are some of the Americas’ top research collaborators and receive funding from US agencies. As a result, they have not been spared from the funding cuts and job losses that are plaguing their US counterparts. #Academicsky πŸ§ͺ

What a week @egu.eu. Lots of interesting presentations and fantastic sunny hot weather in Vienna! Sadly, not enough schnitzels! Oh well, maybe next year. @sheared-sash.bsky.social

The return of the pre-EGU fieldtrip through the Austrian Bohemian Massif was a fantastic way to kickoff the conference week. Fantastic weather and fantastic organization made it very enjoyable!

It’s been a hot minute since my last #thinsectionthursday but here’s some things I’m working on these days… anyone else having issues with how2plot in MTEX 6.0? I’ve seen some solutions online.. think they’re working but it’s just so random how orientations get flipped without explicit scripting βš’οΈπŸ§ͺ

πŸ’₯ hot off the press and 4 years in the making! My PhD thesis in all its glory! 2 published papers, 1 nearly ready for submission, and an exciting project in the making, all find a home in the pages within. Super proud of my work at Njord w/ Luca Menegon, Kristina Dunkel, & @sheared-sash.bsky.social

Hey everyone,
Does anyone have a link to a website where you can search for conflict of interests among research collaborators? A few months ago (~Nov 2024), someone shared a link but I haven’t been able to find it or something similar with a google search. πŸ§ͺ βš’οΈ

(3) Repeated fragmentation and comminution in addition to fluid at the grain boundaries are required to facilitate viscous deformation

We find that
(1) Plagioclase in the damage zone of a lower-crustal pseudotachylyte deformed via pulverization-style fragmentation

(2) Liberated H2O as a result of the earthquake remained in grain boundary regions and facilitated neoblast growth and healing of fractures

Orientation map (IPFZ) of diopside that formed from the breakdown of omphacite, a high pressure mineral.

This is a map showing the orientation of diopside in a deformed symplectite. This used to be an omphacite, which tells us that the rock used to be at very high pressure (great depth). βš’οΈπŸ§ͺ

If you want to read more about how such symplectites nucleate and deform:
