Summary: Hybrid polysiloxanes and polysilsesquioxanes grafted with naturally occurring bioactive phytochemicals, eugenol and linalool, were synthesized and their structure and properties were investigated. The antibiofilm activities of the materials were assessed on glass plates coated with different types and contents of active groups using luminometry and fluorescence microscopy. The specific properties of the hybrid coatings, such as chemical structure, surface free energy, and adhesiveness, were correlated with bioactivity. The functionalized polysilsesquioxanes showed the most favorable anti-adhesive effects.

Summary: Researchers have developed a color conversion layer (CCL)-based, full-color, highly efficient micro-light emitting diode (mu LED) array to address the challenges of mass transfer yield in mu LED technology. By combining CCL with a color purity enhancement film, they achieved 7 μm x 7 μm subpixel fluorescent arrays with a color gamut of 95.34% in DCI-P3 and an overall 1588 PPI. This study provides a promising technique for fabricating higher pixel density-based next-generation display technology.

Summary: This study conducted constant moisture stress-accelerated degradation tests on silicone encapsulant with different thermal stresses, and predicted its real lumen decay and color shift lifetimes by integrating the accelerated lifetime model with the Gamma process model. The results showed that the degradation rate of silicone encapsulant is related to thermal stress, and the prediction accuracy varies when using lumen decay lifetime versus color shift degradation data.

Summary: This study presents the preparation of a new eternally alive adhesive using silicone pressure-sensitive adhesives with clinoptilolite. Neat and acid-modified clinoptilolite were used, and the effect of acid treatment on the adhesive properties of pressure-sensitive adhesive tapes was tested. The results demonstrated that the obtained tapes showed increased thermal resistance while maintaining good functional properties, suggesting promising implementation potential for self-adhesive materials where increased thermal resistance is required.

Summary: The addition of DCP and KH570 can significantly improve the tensile shear strength of the hot melt adhesive, while the addition of silane coupling agents with different functional groups has minimal impact on the performance. However, excessive silane coupling agent may reduce the tensile strength and shear peel strength of the material.

Summary: The relationship between adhesive joint properties and the amount of surfactant at the surface was studied in this research. It was found that as the amount of contaminant increased, the adhesive bond strength decreased and the failure mode changed from cohesive to adhesive. Numerical modeling supported the experimental results.

Summary: Hybrid structural electronics (HSE) combines printed electronics, conventional rigid electronics, and load-bearing supporting parts, such as flexible lighting elements with embedded LEDs. A two-step hybrid method was used to simulate the thermal behavior of surface-mounted LEDs, showing high accuracy in comparison to measurements. This provides a basis for designing structural LED elements and predicting their performance characteristics.

Summary: In this article, a new highly efficient Mn4+ ion-activated Li3La3W2O12 (LLWO) far-red emitting phosphor was synthesized and characterized. The LLWO:Mn4+ phosphors exhibited bright narrowband far-red emission peaking at 719 nm, which matched well with the absorption spectrum of phytochrome PFR. The phosphors could be efficiently excited by both ultraviolet and blue LED chips, and a LED device utilizing the LLWO:1.2%Mn4+ phosphor showed dual emission bands of blue and far-red.
