The physiological and pathological processes in lungs indicated that ONOO- acted as an informative indicator for pulmonary functioning status with the corresponding dynamics, especially permissive hypercapnia. Herein, peroxynitrite (ONOO-) detection imaging living lung cells, imidazo-pyridin derived fluorescent probe IDPD-ONOO was developed. recognized to exhibit a fluorescence response at 490 nm excitation wavelength 355 nm. advantages of developed included practical linear range (0-100...
Iodide-based perovskites are severely limited in practical applications due to their low photoluminescence quantum yield (PLQY), tendency undergo phase separation, and severe PL quenching the solid state. Herein, a bilayer core-shell structured perovskite nanocomposite containing Br I (BINC), based on Förster resonance energy transfer (FRET), is prepared. In BINC structure, embedded silica titanium dioxide define Si-BINC Ti-BINC structures, respectively, serving as barrier between donor...
CsPbBr3/SiO2 heterostructures were synthesized by the hydrolysis reaction of a mixture CsPbBr3 nanocrystals (NCs) and (3-aminopropyl)triethoxysilane (APTS) in air. Compared with NCs, exhibit stronger photoluminescence (PL) intensity, longer lifetime PL (∼40.5 ns), higher PL-quantum yield (PLQY, ∼86%). The carrier dynamics was detected transient absorption (TA) spectrum. experimental results show that SiO2 passivates surface traps NCs enhances intensity. However, photoelectrochemical...

The damage problem of fused silica has always been one the bottlenecks limiting energy output high-power laser system. For optical components, ionization breakdown by is main factor causing damage, especially for plasma shock wave, which can cause large-scale fracture in silica. In this paper, experiment was induced nanosecond laser, and morphology thickness range 0.8-5.0 mm obtained under action 1-20 pulse. size decreases as material increases until greater than or equal to 1.4 mm. On basis...
The damage to the rear surface of fused silica under action high power laser is more severe than that incurred by front surface, which hinders improvement in energy device. For optical components, ionization breakdown a main factor causing damage, particularly with plasma shock waves, can cause large-scale fracture silica.

Abstract The morphology of totally inorganic metal halide perovskites has a certain influence on their optoelectronic properties. In this study, one-dimensional CsPbBr 3 nanorods (NRs) and nanowires (NWs) were arranged utilizing boiling injection strategy. By controlling the processing time, NRs with length roughly 63 nm NWs 300 obtained, it was found that grown from nanorods. Temperature-dependent photoluminescence (PL) measurements conducted NWs, exhibit more stable excitonic state at high...
Coastal regions in China have long been plagued by tropical cyclone (TC) disasters, and TC vulnerability function for disaster-bearing bodies is a widely used quantitative assessment method face of TCs. functions may vary across different due to geographical heterogeneity, hindering this from universal use.
