Summary: Effective utilization of sunlight for chemical reactions is crucial for addressing energy and environmental issues. Current efforts in the development of semiconductor photocatalysts focus on UV and visible light responsiveness, while near infrared and infrared light, which account for about 50% of solar energy, is often wasted due to insufficient photon energy for band gap excitation. However, antimony doping into SnO2 induces strong absorption in the NIR region, enabling conversion of absorbed light energy to heat through the interaction between hot electrons and phonons. This concept highlights the potential of ATO nanocrystals for photothermal enhancement of liquid-phase oxidation reactions.

Summary: The Bi/Sn-doped aluminosilicate glass samples were prepared by a melting-quenching method, and their near-infrared (NIR) emission properties were investigated. It was found that all samples exhibited an ultra-broadband NIR emission ranging from 950 nm to 1600 nm under 480 nm excitation, covering the entire low-loss window of fiber. The NIR emission spectrum showed a maximum emission peak at around 1206 nm with a full width at half maximum (FWHM) of approximately 220 nm. Additionally, the NIR emission intensity strongly depended on the composition of the glass, which could be optimized by adjusting the glass composition. The study proposed that Bi/Sn-doped aluminosilicate glass has great potential to be a new type of core fiber material and applied in optical fiber amplifiers (OFAs) due to its excellent performance in ultra-broadband NIR emission.

Summary: Light in the near-infrared (NIR) spectral region is increasingly used in bioapplications due to its deeper penetration in biological tissues. Lanthanide-doped luminescent nanoparticles with excitation and/or emission in the NIR range are gaining attention for noninvasive biological applications, offering unique optical properties such as large Stokes shift, sharp luminescence emissions, long lifetimes, and photostability. Advanced strategies for enhancing the luminescence brightness of these nanoparticles have been introduced, along with a review of their superior biophotonic applications in high-resolution imaging, single-nanoparticle-level detection, and tissue-penetrating diagnostics and therapeutics.

Summary: The raw materials ratio of magnesium oxychloride (MOC) cement was optimized using the response surface method (RSM) to improve its mechanical properties. The compressive strength of MOC cement was analyzed by single-factor tests, and the optimal ratio was determined to be 7.56:1:13.51 for MgO:MgCl2:H2O. Experimental results showed a 6.29% increase in compressive strength compared to the predicted values, with factors contributing to the high strength explained using X-ray diffraction and scanning electron microscopy.
