This study investigated the effect of nanosilver/water-in-kerosene emulsion on thermal and radiative characteristics and pollutant emissions of a liquid burner. The results were compared with the corresponding values resulted from neat kerosene. Light microscopic imaging was used to study microexplosion of the fuel droplets. Also, combining chemiluminescence technique and measurement of pollutant concentrations, a qualitative study was carried out to find out the effect of CO, CO2, water vapor, and intermediate soot particles on the flame emissivity coefficient. The results showed that the Brownian motion of silver nanoparticles and localized convection between nanoparticles and the adjacent fluids increased the evaporation rate of nanoemulsion droplets and the rate of their mixing with oxidizing air. Besides the nanoparticles effect, the secondary injection of nanoemulsion due to microexplosion of water droplets enhanced the mixing rate of nanoemulsion fuel and oxidizing air. Although absorption of heat by water content of nanoemulsion fuel decreased the flame temperature, the nanoemulsion fuel, compared with neat kerosene, enhanced the average radiation of flame by 23%. Further, the results indicated that although CO and CO2 did not change significantly in amount, NOx emission reduced as much as 23.7% when the nanosilver/water-in-kerosene emulsion, instead of neat kerosene, was used.

“…Until now, diverse response signals (e.g. electrochemistry, 47,48 fluorescence, 49 surface plasmon resonance optics 50 ) have been applied in thalassemia GSs. Among them, electrochemical detection has attracted wide attention due to its advantages of low cost, high sensitivity and fast response.…”

“…If they are not treated properly, they will pollute water resources and pose a hidden risk to biological health, so they should be treated before discharging wastewater. Take methylene blue as an example: methylene blue is a cationic thiazine dye, which is widely used in the fields of indicators and medicine due to its stable nature. , However, it is toxic to humans, and acute exposure to methylene blue in humans can lead to vomiting, hypotension, desquamation, and even hemolysis. It can also affect plant bodies and inhibit photosynthesis if covered on the surface of plants, so it is essential to treat the wastewater before it is discharged.…”

Compared with natural enzymes, nanozymes have advantages such as high stability, low cost, and a broad application prospect. However, due to the low catalytic activity of conventional nanozymes, synthesizing nanozymes with excellent enzyme-like activity will be long-term work. Herein, we synthesized single-atom nanozymes centered on Mn with N, P, and S doped (Mn-SAzyme) with enhanced peroxidase-like (POD-like) activity. We found that the presence of the Mn metal center significantly increased the POD-like activity of the nanozyme, exhibiting catalytic properties consistent with Michaelis–Menten kinetics. The POD-like activity was measured to be 17.48 U/mg, which was higher than that of the sample without the metal center. Using methylene blue (MB) as the organic dye model, the degradation efficiency of Mn-SAzyme could reach 90.1% within 300 min at pH 6.5, within the H2O2 concentration of 0.1 M and 25 mg/L of nanozyme dosage. Free radical quenching experiments and electron paramagnetic resonance tests showed that •O2 – and •OH were the key to degrading organic dyes. This work aims to explore more methods for synthesizing highly active nanozymes and successfully applying the synthesized nanozymes to the degradation of organic dyes.
