The instability of lead halide perovskites (LHPs) has tremendously hindered their practical applications. Although some examples on encapsulating LHPs into a SiO2 shell have been reported, these SiO2-coated still suffer from limited stability. Herein, MAPbBr3 (MA = CH3NH3+) nanoparticles encapsulated in double hydrophobic shells organic functionalized and poly(vinylidene fluoride) (MAPbBr3@SiO2/PVDF) are successfully synthesized by infiltrating the precursor solution hollow siliceous...
The peroxide number of edible oil relates to its quality. classical determination methods for the are still unsatisfactory due their complexity and poor reproducibility in analytical process incapability field rapid detection. In this study, a novel wavelength-shift-based visual method has been developed using halide perovskite nanocrystals (CsPbBr3 NCs). analysis, sample underwent redox reactions with part oleylammonium iodide (OLAM-I) advance. Then, halogen exchange occurred between added...
The defect-tolerant nature of lead halide perovskites renders outstanding luminescence by simple space-confined growth in nanopores. fluorescence turn-on and wavelength-shift phenomena could be found the formation methylammonium tribromide (MAPbBr3) nanocrystals hollow SiO2 nanospheres triggered reaction between methylamine (MA) gas HPbBr3/PbBr2@SiO2 nanospheres. enhanced intensity is linear with MA concentration range 1.0-95 ppm a limit detection (LOD) 70 ppb (S/N = 3). In addition, maximum...
Abstract The detriments of intrinsic silanol groups in mesoporous silica to the photoluminescence (PL) lead halide perovskite nanocrystals (LHP NCs) confined template have never been determined and clearly elucidated. Here, we disclose that silanol‐induced Cs + Br − deficiencies prompt generation traps CsPb 2 5 impurities. temperature‐dependent PL spectra verify higher energetic barrier trap states CsPbBr 3 NCs silanol‐rich silica. Femtosecond transient absorption reveal trapped state...
The tea plant (Camellia sinensis) is rich in polyphenolic compounds. Particularly, flavan-3-ols and proanthocyanidins (PAs) are essential for the flavor disease-resistance property of leaves. fifth subgroup R2R3-MYB transcription factors comprises primary activators PA biosynthesis. This study showed that 5 R2R3-MYBs plants contained at least nine genes belonging to TT2, MYB5, MYBPA types. Tannin-rich an expansion number compared with other dicotyledonous monocot plants. MYBPA-type were...
Abstract Temperature sensing based on fluorescent semiconductor nanocrystals has recently received immense attention. Enhancing the trap‐facilitated thermal quenching of fluorescence should be an effective approach to achieve high sensitivity for temperature sensing. Compared with conventional nanocrystals, defect‐tolerant feature lead halide perovskite (LHP NCs) endows them density defects. Here, hollow mesoporous silica ( h ‐SiO 2 ) template‐assisted ligand‐free synthesis and halogen...

In this study, monodisperse, uniform, and spherical covalent organic frameworks (COFs) were synthesized using 1,3,5-tris (4-aminophenyl) benzene 1,3,5-tricarboxaldehyde at room temperature. Post-modification of 6-aminocaproic acid on the COFs yielded carboxyl-modified (COFs-COOH).
