A simple method for phosphate (Pi) detection is established by developing an off–on fluorescence probe of europium-adjusted carbon dots (CDs), which has been successfully applied to the Pi in very complicated matrixes such as artificial wetlands system.
In this paper, a nanosized porous metal–organic framework, Fe-MIL-88NH2, was facilely prepared with uniform octahedral shape by the addition of acetic acid, and for first time demonstrated to possess intrinsic peroxidase-like activity. Kinetic analysis electron spin resonance measurements indicated that catalytic behavior consistent typical Michaelis–Menten kinetics follows ping-pong mechanism. As novel peroxidase mimic material, Fe-MIL-88NH2 shows advantages high efficiency, ultrahigh...

The photo-Fenton reaction is a promising method to treat organic contaminants in water. In this paper, Fenton reagent enhanced by microwave electrodeless ultraviolet (MWEUV/Fenton) was proposed for advanced treatment of nonbiodegradable substance pesticide-containing biotreated wastewater. MWEUV lamp found be more effective chemical oxygen demand (COD) removal than commercial mercury lamps the process. pseudo-first order kinetic model can well describe COD from wastewater MWEUV/Fenton, and...
Abstract A high‐level reverse intersystem crossing (HL‐RISC, T 2 → S 1 0 + hν ) process has recently been discovered as a promising route for achieving highly efficient organic light‐emitting diodes (OLEDs), but the prerequisites occurrence of HL‐RISC in rubrene is still vague and reported external quantum efficiencies (EQEs) rubrene‐doped OLEDs are typically limited to several percent. Herein, using fingerprint magneto‐electroluminescence tools, it found that energy confinement high‐lying...
Using the fingerprint magneto-electroluminescence trace, we observe a fascinating high-level reverse intersystem crossing (HL-RISC) in rubrene-doped organic light-emitting diodes (OLEDs). This HL-RISC is achieved from high-lying triplet states (T2,rub) transferred host by Dexter energy transfer to lowest singlet (S1,rub) rubrene. Although decreases with bias current, it increases lowering temperature. contrary temperature-dependent RISC conventional thermally activated delayed fluorescence,...
Tricomponent exciplex-based organic light-emitting diodes (TE-OLEDs) with high- and low-energy exciplexes have recently gained much attentions because of their already-reported high external quantum efficiency (EQE) exciplex-to-exciplex energy transfer (EE-ET) is considered as an important factor to influence the device performance. However, few works provide evidence prove this EE-ET process due lack absorption band exciplexes. Herein, channel from a high-energy exciplex donor (EXED)...
Abstract Although high‐efficiency host‐sensitizer‐TBRb‐based organic light‐emitting diodes (HST‐OLEDs) are widely reported, the reasons for their high performances still vague because important role of hot exciton in TBRb emitter (T 2, ) has not been recognized previously. Herein, a maximum external quantum efficiency (EQE) 24.9% is obtained from HST‐OLED by co‐doping Ir(ppy) 3 sensitizer and into CBP host. Such remarkable mainly attributed to efficient utilization T via cascade Dexter...
Twenty-two coumarins and twenty-six flavonoids were quantitated in fingered citron different growth periods. Limettin was the top coumarin, diosmin highest flavonoid, followed by hesperidin. Antioxidant evaluation DPPH, ABTS, FRAP indicated extracts of three periods all showed good antioxidant activity, which positively correlated with concentration extracts. The oxidative stress model RAW264.7 cells from effectively reduced contents NO, MDA, ROS increased activity SOD, thereby alleviating...
With the constantly escalating demand for safe food packaging, utilization of biodegradable polysaccharide-based nanocomposite films is being explored as an alternative to traditional petrochemical polymer (polyvinyl alcohol, polybutylene succinate, etc.). Polysaccharide-based have excellent mechanical properties, water vapor transmission rates, and other physical characteristics. Films can fulfill numerous demands fruit packaging in daily life. Additionally, they be loaded with various...
Pyrophosphate ion (PPi) is crucial in varieties of biological processes and industrial applications, thus it very important how to recognize with high selectivity.
