🚨New Preprint: "Angular Resolution Enhancement of Electron Backscatter Diffraction Patterns" by @bmatb.expmicromech.com and @tbizh95.bsky.social

arxiv.org/abs/2509.23039
Figure from the paper which shows that you can get an angular improvement in the EBSD pattern by using a super resolution method, above what is expected from simply counting longer.
But that is actually probably fair. A2 is IELTS band ~3.5-4, and the very first time I took an IELTS test (age 17) I was already in band 7 (B2-C1), and then after 11 years in Canada I'm at band 8.5 (C2).

(And certain classmates judge me harshly for using Duolingo. Sure...)
Tried to sign up for a French class and took a placement test, hoping I can skip the very basics. Was initially happy that I "have A2 level", then found out that pretty much everyone who can say simple and complete sentences is placed into A2 classes.
If only there is a tool to auto-update the line number references in a response to review comments document. Maybe LaTeX can do it?
Meet the paper which I wrote in half a day (1st draft), and then almost didn't want to continue on...

🚨📜: "Practical Considerations for Crystallographic and Microstructure Mapping With Direct Electron Detector-Based Electron Backscatter Diffraction" by @tbizh95.bsky.social, Ruth Birch, Graeme Francolini, Ebru Karakurt, @bmatb.expmicromech.com in Microscopy and Microanalysis doi.org/10.1093/mam/...
Graphical abstract showing the experimental overview, and a brief overview of the results from the paper.
On behalf of @expmicromech.com - the latest version of AstroEBSD is released, adding the newly developed AstroECP tool to our toolbox (see our preprint announcement). Also we (finally) tidied up the readme files, added descriptions of new features over the years, and created a change log.
Happy about this - the biggest collaboration project in my PhD :) and collaboration is indeed the spirit throughout the course.

Never thought this dataset could lead us here. As someone must have said, there are still so many information in these pats that one could look into and extract info...

🚨New #PrePrint - "Characterization of WSe2 films using reflection Kikuchi diffraction in the scanning electron microscope and multivariate statistical analyses" @tbizh95.bsky.social, J Holzer, T Vystavěl, M Kolíbal, E Paiva de Araújo, C. Stephens & @bmatb.expmicromech.com

arxiv.org/abs/2506.22575
Graphical abstract - showing the experimental set up for the analysis of WSe2 films, the data clustering method, analysis of the diffraction patterns, and diffraction patterns from one, two and three layer WSe2 films
Switching from direct electron detection to direct photon detection, at least for an hour.

So we recently installed a new TFS Apreo 2 S microscope at UBC - and it has a TruePix direct electron detector for electron backscatter diffraction analysis.

In only 1 week, we are already getting some very fun data (here from Ni - 2 mill pts in < 30 mins). 🧪🔬

🚨New #ArXiv #PrePrint:

"Comparison of Kikuchi Diffraction Geometries in Scanning Electron Microscope" by
@tbizh95.bsky.social, Lukas Berners, Jakub Holzer, @bmatb.expmicromech.com

Exploring on- and off-axis TKD, EBSD and RKD geometries for crystallographic analysis

arxiv.org/abs/2411.13018
Figure 2 from the paper that shows: 

"Experimental stages and typical raw, background corrected Kikuchi patterns from the four diffraction geometries. Indexed patterns with pattern centre and selected bands overlaid are also shown."
(one way to ask for help with writing an abstract)

Wouldn't it be more fitting to simulate spot patterns using a "dotnet" language than a snake language 😂
UPass is now $46 per month, good for buses, MRT... in metro Vancouver.
Deutschland ticket is $49 per month, good for buses, MRT, local trains... across Germany. Barring the annoying delays of DB these days, it's really a great deal.
Solid beverage choice for us diffraction people?
Workday students is such a downgrade from the super user-friendly UBC SSC..........
