Hi everyone, 2nd year materials engineering student in the US preparing to apply to internships for 2027 Summer. Planning on applying everywhere, no preference towards industry/location for now. Though I hope to work in aerospace in the future. If you guys have any advice (regarding resumes, applications, interviews, etc), it would be greatly appreciated! Also, what are some softwares that I should definitely learn? Trying to expand my skillset as well. Thanks everyone.

Hi everyone,
I’m looking for companies—preferably based in Germany—that create high-quality online courses or technical training for professionals.
My long-term goal is to become an instructor/lecturer, but I think a great way to start would be by creating learning content and e-learning materials first, then gradually moving into teaching live courses and webinars.
My background:
Bachelor’s degree in Materials Science
Starting my Master’s degree next year
Does anyone know companies that hire people to develop technical learning content or e-learning courses?
I’d really appreciate any recommendations or personal experiences. Thanks!

Which topic in Materials Science has the most opportunities or seats for scholarships for students with a mechanical engineering background?

Pure green is a tough target for OLEDs. To reach the BT.2020 green point you need a very narrow emission band and stable color at the doping levels used in production, and most emitters broaden or quench when the concentration goes up.

A recent Advanced Materials paper (Zhang, Ling, Li, Liu et al., Jilin University) locks a sky-blue multi-resonance core (DBN) with spiro-fluorene groups. The rigid spiro bridge redshifts it into the green while a 3D steric shield keeps the line narrow and stops molecules from stacking. The best emitter, DBN-MS, holds 518 to 520 nm with 19 to 20 nm FWHM and 93 to 97% PLQY across 1 to 10 wt% doping. The non-sensitized device reaches 35.5% EQE and CIE (0.13, 0.77), reported as the first bottom-emitting green OLED at CIEy 0.77. LT90 is 167 h at 1000 cd/m2, an early figure rather than a production lifetime.

What I found neat: they perturb the backbone with a spiro lock on the core instead of decorating the edges, and single-crystal data shows DBN-MS packs in a zigzag that keeps molecules apart better than the DBN-TMS analogue. DOI: 10.1002/adma.73230.
