Multi-Pitch Liquid Crystal Filters with Single Layer Polymer Template.
Zhu Z, Gao Y, Lu J. Zhu Z, et al. Polymers (Basel). 2021 Jul 30;13(15):2521. doi: 10.3390/polym13152521. Polymers (Basel). 2021. PMID: 34372123 Free PMC article.
Multi-reflective peak and bandwidth scalable liquid crystal (LC) filters were investigated. By refilling a cholesteric LC (CLC) whose chiral pitch is different to the target template into a blue phase LC (BPLC) template, a multi-reflective peak single layer LC filte …

Changing Liquid Crystal Helical Pitch with a Reversible Rotaxane Switch.
Chen S, Katsonis N, Leigh DA, Patanapongpibul M, Ryabchun A, Zhang L. Chen S, et al. Angew Chem Int Ed Engl. 2024 Apr 24;63(18):e202401291. doi: 10.1002/anie.202401291. Epub 2024 Mar 26. Angew Chem Int Ed Engl. 2024. PMID: 38445723
Here we demonstrate that the dynamic change in the expression of the chirality of a rotaxane can be transduced into a change in pitch of a soft matter system. Shuttling the position of the macrocycle from far-away-from to close-to a point-chiral center on the rotaxane axle …

Polyethylene glycol regulates the pitch and liquid crystal behavior of cellulose nanocrystal-based photonic crystals.
Qi Y, Wang S, Sun J, Song J, Li H, Guo J. Qi Y, et al. Int J Biol Macromol. 2024 Mar;260(Pt 1):129544. doi: 10.1016/j.ijbiomac.2024.129544. Epub 2024 Jan 18. Int J Biol Macromol. 2024. PMID: 38244739
One of the most important development directions of photonic crystals is the diversification of colors, usually by adjusting the pitch. However, few researchers notice the effect of polymer molecular weight and content on pitch regulation and the interaction between …

Pitch Gradation by Ion-Dragging Effect in Polymer-Stabilized Cholesteric Liquid Crystal Reflector Device.
Hu X, Zeng W, Zhang X, Wang K, Liao X, Jiang X, Jiang XF, Jin M, Shui L, Zhou G. Hu X, et al. Polymers (Basel). 2020 Jan 4;12(1):96. doi: 10.3390/polym12010096. Polymers (Basel). 2020. PMID: 31947917 Free PMC article.
An IR reflector based on polymer-stabilized cholesteric liquid crystal (PSCLC) can selectively tune IR light reflection for smart window application. ...Consequently, a frozen pitch gradient by such an in-situ-electric-field-assisted dynamic ion-dragging effect lead …

Temperature-independent pitch invariance in cholesteric liquid crystal.
Shim KS, Heo JU, Jo SI, Lee YJ, Kim HR, Kim JH, Yu CJ. Shim KS, et al. Opt Express. 2014 Jun 30;22(13):15467-72. doi: 10.1364/OE.22.015467. Opt Express. 2014. PMID: 24977806 Free article.
We report a pitch invariance in cholesteric liquid crystals (CLCs) independent of temperature by mixing two chiral dopants. One dopant tends to shorten the helical pitch of the CLC, but the other makes the pitch longer, with increasing temperatures. .. …

Reduced Maximum Pitch Elevation Predicts Silent Aspiration of Small Liquid Volumes in Stroke Patients.
Rajappa AT, Soriano KR, Ziemer C, Troche MS, Malandraki JB, Malandraki GA. Rajappa AT, et al. Front Neurol. 2017 Aug 25;8:436. doi: 10.3389/fneur.2017.00436. eCollection 2017. Front Neurol. 2017. PMID: 28890708 Free PMC article.
BACKGROUND AND PURPOSE: Preliminary evidence has shown that reduced ability to maximally raise vocal pitch correlates with the occurrence of aspiration (i.e., airway invasion by food or liquid). ...CONCLUSION: In stroke patients (<1 month poststroke), reduced max …
