Sulfamethoxazole (SMX) is a common antibiotic that considered an emerging pollutant of water bodies, as it toxic for various aquatic species. TiO2-based photocatalysis promising method SMX degradation in water. In this work, TiO2/zeolite (Z-45 loaded with TiO2 labeled TZ and ZSM-5 TZSM) composites were prepared by mechanical mixing liquid impregnation methods, the photocatalytic performance these (200 mg·L−1) was investigated toward (30 under UV light (365 nm). The pseudo-first-order...
TiO2 nanoparticle-based dye-sensitized solar cells (DSSCs) were modified by depositing a layer of long-persistent phosphor, SrAl2O4:Eu2+,Dy3+, on top the nanoparticle to prepare working electrodes DSSCs. SrAl2O4:Eu2+,Dy3+ red-shifted short UV wavelengths into main absorption range dye commonly used in The also acted as light-scattering reduce loss visible light. Incident photon current conversion efficiency measurements showed that application such phosphor materials enhanced...
Perovskite solar cells (PSCs) with a standard sandwich structure suffer from optical transmission losses due to the substrate and its active layers. Developing strategies for compensating in light harvesting is of significant importance achieving further enhancement device efficiencies. In this work, down-conversion effect carbon quantum dots (CQDs) was employed convert UV fraction incident into visible light. For this, thin films poly(methyl methacrylate) embedded (CQD@PMMA) were deposited...
To date, Ag-based nanomaterials have demonstrated a high potential to overcome antibiotic resistance issues. However, bare Ag are prone agglomeration in the biological environment, which results loss of antibacterial activity over time. Furthermore, it is still challenging collect small-sized right after synthesis process. In this study, spherical-shaped nanoparticles (NPs) (~6–10 nm) were attached on surface cetyltrimethylammonium bromide (CTAB)-loaded mesoporous silica (MSNs) (~100–110...
Synthesizing monodisperse afterglow microparticles (MPs) is crucial for creating photonic crystal (PC) platforms with multiple optical states optoelectronics.

Photodynamic and photothermal therapies are promising treatments for cancer, dermatological, ophthalmological conditions. However, photodynamic therapy (PDT) is less effective in oxygen-deficient tumor environments. Combining PDT with (PTT) can enhance oxygen supply treatment efficacy. Inorganic PTT agents pose toxicity risks, limiting their clinical use despite high performance. In this study, we developed a novel nanomedicine integrating an all-organic agent organic photosensitizer,...

Laser conversion of metal-organic frameworks (MOFs) has recently emerged as a fast and low-energy consumptive approach to create scalable MOF derivatives for catalysis, energy, optics. However, due the virtually unlimited structures tunable laser parameters, results their interaction are unpredictable poorly controlled.

Solar cells have been developed as a highly efficient source of alternative energy, collecting photons from sunlight and turning them into electricity. On the other hand, ultraviolet (UV) radiation has substantial impact on solar by damaging their active layers and, result, lowering efficiency. Potential solutions include blocking UV light (which can reduce power output cells) or converting visible using down-conversion optical materials. In this work, we propose novel hydrophobic coating...
