Hydrogen‐Bond Mediated Structural Evolution and Mechano‐Optical Anisotropy During Drying and Uniaxial Stretching of Poly(Vinyl Alcohol) Films: Effect of Molecular Weight

open access: yesPolymer Engineering &Science, Volume 66, Issue 1, Page 172-189, January 2026.
Morphological Evolution in stretched PVA films. ABSTRACT This study presents a systematic investigation of the structural and mechano‐optical evolution of 88% hydrolyzed poly(vinyl alcohol) (PVA) films from solution casting to uniaxial stretching. The effects of molecular weight, drying conditions, and deformation temperature were examined using real ...

Chemical strengthening of float glasses: Effect of composition and structure

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Two silicate float glasses were considered in the present work: a typical clear soda lime silicate glass and a soda magnesia silicate glass. Both materials underwent chemical strengthening in KNO3, and a different behavior was pointed out in terms of potassium penetration and corresponding surface compression.

Unexpected Sign Inversion of the Circular Dichroism and Circularly Polarized Luminescence Response of Chiral Copolymer Thin Films by Tuning the Thickness and Annealing Conditions

open access: yesChemPhotoChem, Volume 9, Issue 12, December 13, 2025.
Copolymer thin films with induced supramolecular chirality show promise for chiroptical optoelectronic applications. Sign changes of the strong circular dichroism and circularly polarized luminescence (CPL) of such films are demonstrated by tuning their film thickness and annealing conditions.

THE PHOTOELASTICITY OF RHOMBIC SYNGONY CRYSTALS

open access: yesЕлектроніка та інформаційні технології
The Rb2SO4 crystals were synthesized by slow evaporation of room-temperature aqueous solution of pure rubidium sulfate salts that had been recrystallized many times. The solution temperature was 310 K, controlled by a thermostat with an accuracy of 0.5 K.

A dynamic tactile sensor on photoelastic effect

open access: yes, 2006
Certain photoelastic materials exhibit birefringent characteristics at a very low level of strain. This property of material may be suitable for dynamic or wave propagation studies, which can be exploited for designing tactile sensors.
