Dear #microplastic community. I do not know if you heard of this survey, feel free to participate to this πŸ‡©πŸ‡ͺ initiative. It is important for those analysing βš—οΈ plastic within #solid #matrices.

Methodological differences in the analysis of plastics in solid matrices

How much time and resources do you spend analyzing #plastics in solid matrices? Have you ever wondered if there are more efficient or less expensive #methods that work just as well? We want to find out β€” with your help!

Join us at https://rptu.de/s/solidm

With this survey, we want to assess the time, personnel, and material requirements of your methods to identify best practices.

Your expertise makes all the difference!

#rstats πŸ“¦ #OpenSpecy 1.0 is now out on CRAN with tons of new features including better handling of spectral data, particle analysis, and an #AI classification algorithm πŸ₯³

Check out our new man pages at http://wincowger.com/OpenSpecy-package/ for all the details. A polished #Shiny app is available here for review: https://wincowger.shinyapps.io/reviewer_app/

Shout out to @wincowger and everybody else involved in this massive team effort.

Analyze, Process, Identify, and Share Raman and (FT)IR Spectra

Raman and (FT)IR spectral analysis tool for plastic particles and other environmental samples (Cowger et al. 2021, <doi:10.1021/acs.analchem.1c00123>). With read_any(), Open Specy provides a single function for reading individual, batch, or map spectral data files like .asp, .csv, .jdx, .spc, .spa, .0, and .zip. process_spec() simplifies processing spectra, including smoothing, baseline correction, range restriction and flattening, intensity conversions, wavenumber alignment, and min-max normalization. Spectra can be identified in batch using an onboard reference library (Cowger et al. 2020, <doi:10.1177/0003702820929064>) using match_spec(). A Shiny app is available via run_app() or online at <https://openanalysis.org/openspecy/>.

Just learned about diamond #openaccess today, a community-driven publication model free of charge for both authors and readers. #openscience all the way!

Can you recommend any indexed journals in #soil and #environmental science, analytical #chemistry, or #plasticpollution research supporting πŸ’Ž OA?

@DOAJ lists a few but not too many. And there is this compilation of German πŸ’Ž OA journals: https://pub.uni-bielefeld.de/record/2963331. What about @scipost?
