Plasmons in Li under compression.
Matsuoka T, Ibañez-Azpiroz J, Hiraoka N, Fukui H, Bergara A. Matsuoka T, et al. J Phys Condens Matter. 2019 May 8;31(18):185501. doi: 10.1088/1361-648X/ab0528. Epub 2019 Feb 7. J Phys Condens Matter. 2019. PMID: 30731441
The plasmon peak width ([Formula: see text]) versus momentum transfer (q) curve of bcc-Li below 6.5 GPa keeps similar parabola-like shape. Above 8.4 GPa, where Li is in fcc, it changes from that of bcc-Li and has a convex shape....

The significance of Q-methodology as an innovative method for the investigation of affective variables in second language acquisition.
Li X. Li X. Front Psychol. 2022 Aug 18;13:995660. doi: 10.3389/fpsyg.2022.995660. eCollection 2022. Front Psychol. 2022. PMID: 36059765 Free PMC article. Review.
Q methodology can hopefully be capable of representing the dynamicity and complexity of the affective variables language learners experience in the interactive network of classroom learning. Thus, it is expected that innovative research methods such as the Q methodo
