[Refractive surgery for hyperopia].
Delbarre M, Le HM, Boucenna W, Froussart-Maille F. Delbarre M, et al. J Fr Ophtalmol. 2021 May;44(5):723-729. doi: 10.1016/j.jfo.2020.11.008. Epub 2021 Apr 6. J Fr Ophtalmol. 2021. PMID: 33836914 Review. French.
The anatomical peculiarities of the hyperopic eye (small corneal diameter, short axial length, narrow anterior chamber or large kappa angle) make refractive surgery for hyperopia a considerable challenge. Large optical ablation zones now allow correction of h …

Structure-rheology relationship in monoolein liquid crystals.
Mistry S, Fuhrmann PL, de Vries A, Karshafian R, Rousseau D. Mistry S, et al. J Colloid Interface Sci. 2023 Jan 15;630(Pt B):878-887. doi: 10.1016/j.jcis.2022.10.115. Epub 2022 Nov 1. J Colloid Interface Sci. 2023. PMID: 36356453
Our hypotheses were: (a) liquid crystal symmetry dominates yielding and large deformation, and (b) strain rate frequency superposition (SRFS) may be used to determine mesophase long and short relaxation times. EXPERIMENTS: Liquid crystal microstructure and rheology …

Convergent-beam electron diffraction.
Tanaka M, Tsuda K. Tanaka M, et al. J Electron Microsc (Tokyo). 2011;60 Suppl 1:S245-67. doi: 10.1093/jmicro/dfr038. J Electron Microsc (Tokyo). 2011. PMID: 21844594
The symmetry determination of one-dimensionally incommensurate crystals and quasicrystals is explained. The large-angle CBED technique, which is indispensable for lattice defect and lattice strain analysis, is also described. A real procedure for lattice s …

Twist-angle-controlled neutral exciton annihilation in WS(2) homostructures.
Xu L, Duan W, Liu Y, Wang J, Zhao Y, Li H, Liu H, Liu D. Xu L, et al. Nanoscale. 2022 Apr 7;14(14):5537-5544. doi: 10.1039/d2nr00195k. Nanoscale. 2022. PMID: 35343557
Here, we develop a non-destructive way to control EEA in WS(2) homostructures by changing the interlayer twist angle, and systematically study the effect of interlayer twist angle on EEA, using fluorescence lifetime imaging measurement (FLIM) technology. Due to the …

External Electromagnet FPCB Micromirror for Large Angle Laser Scanning.
Periyasamy KGK, Tan VJ, He S, Kourtzanidis N. Periyasamy KGK, et al. Micromachines (Basel). 2019 Sep 30;10(10):667. doi: 10.3390/mi10100667. Micromachines (Basel). 2019. PMID: 31575067 Free PMC article.
., (1) it reduces the overall width beyond the mirror plate, and (2) increases the maximum rotation angle. The micromirror has two external electromagnets underneath an FPCB structure (two torsion beams and a middle seat) with two moving PM discs attached to the back and a …

Recent advances in experimental design and data analysis to characterize prokaryotic motility.
Dubay MM, Acres J, Riekeles M, Nadeau JL. Dubay MM, et al. J Microbiol Methods. 2023 Jan;204:106658. doi: 10.1016/j.mimet.2022.106658. Epub 2022 Dec 15. J Microbiol Methods. 2023. PMID: 36529156 Free article. Review.
Swimming, the first type of motility described in bacteria, still remains largely unquantified. Light microscopy has enabled qualitative characterization of swimming patterns seen in different strains, such as run and tumble, run-reverse-flick, run and slow, stop an …

Helical Locomotion in Yield Stress Fluids.
Nazari F, Shoele K, Mohammadigoushki H. Nazari F, et al. Phys Rev Lett. 2023 Mar 17;130(11):114002. doi: 10.1103/PhysRevLett.130.114002. Phys Rev Lett. 2023. PMID: 37001094
In the first stage, the swimmer must overcome the material's yield strain to generate rotational motion. However, exceeding the first threshold is not sufficient for locomotion. ...Once locomotion is underway in the third stage, the yield stress retards swimming at small p …
