Abstract

Heat‐activated second harmonic generation (SHG) switching materials are gaining interest for their ability to switch between SHG on and off states, offering potential in optoelectronic applications. The novel nonlinear optical (NLO) switch, (C5H6NO)+(CH3SO3)− (4‐hydroxypyridinium methylsulfonate, 4HPMS), is a near‐room‐temperature thermal driven material with a strong SHG response (3.3 × KDP), making it one of the most potent heat‐stimulated NLO switches. It offers excellent contrast of 13 and a high laser‐induced damage threshold (2.5 × KDP), with reversibility > 5 cycles. At 73 °C, 4HPMS transitions from the noncentrosymmetric Pna21 room temperature phase (RTP) to the centrosymmetric P21/c phase, caused by the rotation of the (C5H6NO)+ and (CH3SO3)− due to partially thermal breaking of intermolecular hydrogen bonds. The reverse phase change exhibits a large 50 °C thermal hysteresis. Density functional theory (DFT) calculations show that (C5H6NO)+ primarily dictates both the SHG coefficient (dij) and birefringence (▵n(Zeiss) = 0.216 vs ▵n(cal.) = 0.202 at 546 nm; Δn(Immersion) = 0.210 vs ▵n(cal.) = 0.198 at 589.3 nm), while the band gap (Eg) is influenced synergistically by (C5H6NO)+ and (CH3SO3)−. Additionally, 4HPMS‐RTP also exhibits mechanochromism upon grinding as well as an aggregation‐enhanced emission in a mixture of acetone and water. [ABSTRACT FROM AUTHOR]

7. Crumb Rubber in Alkaline Activated Clay Roof Tiles at Low Temperature

Author

Abstract

The continuous increase in vehicle uptake escalates the number of rubber tyre waste to avoid landfilling and stockpiling. The present research focused on the sustainable use of crumb rubber in clay roof tiles. Tile samples were fabricated by heating the compacted mixtures at 50°C for 72 h, followed by increasing the temperature to 200°C for 24 h. Clay, crumb rubber, NaOH, and Na2SiO3 with a 10% alkaline activator were adopted. The weight of the crumb rubber was 0.5%, 1%, 1.5%, 2%, and 2.5%. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses to study the phases and microstructures of the samples. The present study found that the optimum crumb rubber concentration was 0.5%, and 1% satisfied the standard requirement for the roof tiles.

23. Remarkable Second Harmonic Generation Response in (C 5 H 6 NO) + (CH 3 SO 3 ) - : Unraveling the Role of Hydrogen Bond in Thermal Driven Nonlinear Optical Switch.

Abstract

Heat-activated second harmonic generation (SHG) switching materials are gaining interest for their ability to switch between SHG on and off states, offering potential in optoelectronic applications. The novel nonlinear optical (NLO) switch, (C 5 H 6 NO) + (CH 3 SO 3 ) - (4-hydroxypyridinium methylsulfonate, 4HPMS), is a near-room-temperature thermal driven material with a strong SHG response (3.3 × KDP), making it one of the most potent heat-stimulated NLO switches. It offers excellent contrast of 13 and a high laser-induced damage threshold (2.5 × KDP), with reversibility > 5 cycles. At 73 °C, 4HPMS transitions from the noncentrosymmetric Pna2 1 room temperature phase (RTP) to the centrosymmetric P2 1 /c phase, caused by the rotation of the (C 5 H 6 NO) + and (CH 3 SO 3 ) - due to partially thermal breaking of intermolecular hydrogen bonds. The reverse phase change exhibits a large 50 °C thermal hysteresis. Density functional theory (DFT) calculations show that (C 5 H 6 NO) + primarily dictates both the SHG coefficient (d ij ) and birefringence (▵n (Zeiss) = 0.216 vs ▵n (cal.) = 0.202 at 546 nm; Δn (Immersion) = 0.210 vs ▵n (cal.) = 0.198 at 589.3 nm), while the band gap (E g ) is influenced synergistically by (C 5 H 6 NO) + and (CH 3 SO 3 ) - . Additionally, 4HPMS-RTP also exhibits mechanochromism upon grinding as well as an aggregation-enhanced emission in a mixture of acetone and water., (© 2024 Wiley-VCH GmbH.)
